# 3 Requirements

Before installing Forms and Reports Services, ensure that your computer meets the requirements described in this chapter.

This chapter contains the following sections:

- System Requirements

- Windows System Files (wsf.exe)

- Ports

- Operating System User

- Environment Variables

- The Hosts File

- Network Topics

- Prerequisite Checks Performed by the Installer

## 3.1 System Requirements

Table 3-1 lists the system requirements for installing Forms and Reports Services.

The installer checks many of these requirements at the start of the installation and displays a warning if any of the requirements is not met.

You can also run the system checks performed by the installer by running the `setup.exe` command. The `setup.exe` command is on the Forms and Reports Services CD-ROM (Disk 1) or DVD-ROM (in the `orawinfrs` directory).

CD-ROM (assumes E: is the CD-ROM drive):

    E:\> setup.exe -executeSysPrereqs

DVD-ROM (assumes E: is the DVD-ROM drive):

    E:\> cd orawinfrs
    E:\orawinfrs> setup.exe -executeSysPrereqs

The results are displayed on the screen as well as written to a log file. For more information on the types of checks performed, see Section 3.8, "Prerequisite Checks Performed by the Installer".

Table 3-1 System Requirements

Item | Requirement | Checked by the Installer
--- | --- | ---
Operating system | Microsoft Windows 2000 with Service Pack 3 or later Microsoft Windows Server 2003 (32-bit) with Service Pack 1 Microsoft Windows XP is supported only for these two types: - J2EE and Web Cache middle tier without Oracle Application Server Infrastructure - J2EE and Web Cache middle tier running on Windows XP, using services from an OracleAS Infrastructure running on a different (non-XP) platform - OracleAS Developer Kits You can install other Forms and Reports Services installation types on Windows XP (the installer displays a warning, but lets you continue), but they are not supported on Windows XP. If you are running Windows XP with Service Pack 2, see Document ID 280874.1 on the OracleMetaLink site (`http://metalink.oracle.com`.). Note: Forms and Reports Services is not supported on Windows operating systems that include Terminal Services. For example, Windows 2000 with Terminal Services is not supported. | Yes
Network | You can install Forms and Reports Services on a computer that is connected to a network, or on a standalone computer (not connected to the network). If you are installing Forms and Reports Services on a standalone computer, you can connect the computer to a network after installation. You have to perform some configuration tasks when you connect it to the network; see the Oracle Application Server Administrator's Guide for details. Note: The Reports default broadcast discovery mechanism requires the host machine to be inside a network. If the host machine is not in a network (that is, it is a standalone machine), then the in-built broadcast mechanism does not work. As a result, you cannot use OracleAS Reports Services. Specifically, Oracle Reports clients cannot discover and communicate with Reports Server(s). Note that the definition of a "network" does not include a Virtual Private Network (VPN). That is, even if the host machine is connected to the network through VPN, Oracle Reports clients cannot discover and communicate with Reports Server(s). Therefore, if your installation is on a standalone (non-networked) host machine or you are connected to a network through VPN, turn off the Reports out-of-the-box broadcast mechanism, and turn on the Reports naming service support for discovery instead. For information on turning on the naming service, see the Oracle Application Server Reports Services Publishing Reports to the Web manual. | No
IP | You can install Forms and Reports Services on a computer that uses static IP or DHCP-based IP. | No
Processor Speed | 300 MHz Intel Pentium processor | Yes
Memory | The memory requirements provided for the various installation types represent enough physical memory to install and run Forms and Reports Services. However, for most production sites, you should configure at least 1 GB of physical memory. For sites with substantial traffic, increasing the amount of memory further may improve your performance. For Java applications, either increase the maximum heap allocated to the OC4J processes, or configure additional OC4J processes to utilize this memory. See the Oracle Application Server Performance Guide for details. In determining the optimal amount of memory for your installation, the best practice is to load test your site. Resource requirements can vary substantially for different applications and different usage patterns. In addition, some operating system utilities for monitoring memory can overstate memory usage (partially due to the representation of shared memory). The preferred method for determining memory requirements is to monitor the improvement in performance resulting from the addition of physical memory in your load test. Refer to your platform vendor documentation for information on configuring memory and processor resources for testing purposes. Forms and Reports Services: 1GB If you do not meet the memory requirements, the installer displays a warning. The installer lets you dismiss the warning and continue because you may configure some but not all components and thus require less memory. However, you should test your site to ensure that you do have sufficient memory. | Yes
Disk space | 800 MB | No
Space in TEMP directory | 55 MB | Yes
Total Pagefile size (Virtual Memory) | 1.5 GB To view and change the total pagefile size (virtual memory): Windows 2000: Select Start > Settings > Control Panel > System. Select the Advanced tab. Click Performance Options. Click Change to review and change the virtual memory setting. | Yes
Monitor | 256 color display | Yes
Supported browsers | For the most current list of supported browsers, check the OracleMetaLink site (`http://metalink.oracle.com`). The following browsers are supported: Microsoft Internet Explorer 5.5, 6.0 and higher On Windows XP with SP2, use the Microsoft Internet Explorer 6.0.2900.2180.xpsp_sp2_rtm.040803-2158. This is the version packaged with SP2. Netscape 7.1, 7.2 Mozilla 1.5, Mozilla 1.7. You can download Mozilla from `http://www.mozilla.org`. Note that Firefox, the standalone Mozilla browser, is currently not certified. But check the OracleMetaLink site (`http://metalink.oracle.com`) for the most current list of certified browsers. Safari 1.2 (on Apple Macintosh computers) Adobe Acrobat Forms applications require a JVM running within a browser. The following browsers and JVM combinations are currently supported: Microsoft Internet Explorer 6.0 and higher with native JVM or JInitiator 1.3.1.13 and higher Netscape 4.7x, 7.0x and higher with JInitiator 1.3.1.13 and higher or Sun Java Plugin 1.4.1 and higher More browsers and JVMs will be certified over time. For the latest information on which browsers and JVMs are certified for Forms, check Oracle Technology Network (OTN): (`http://otn.oracle.com/products/forms/htdocs/10g/clientsod_forms10g.html`) | No

Tips for Reducing/Fine Tuning Memory Usage

If you need to reduce memory consumption:

- After installation, use Oracle Enterprise Manager to stop services not used. This reduces the memory usage. For details, see the Oracle Application Server Administrator's Guide.

- For OracleAS Reports Services, you can control the JVM heap size by specifying small values using the `REPORTS_JVM_OPTIONS` environment variable.

  For Reports Engine, the JVM options are specified in the `server_name``.conf` file in the `jvmoptions` attribute of the `engine` element. If specified, the JVM options set in `server_name``.conf` override the value of the `REPORTS_JVM_OPTIONS` environment variable. If not specified in `server_name``.conf`, Oracle Reports uses the JVM options specified by the `REPORTS_JVM_OPTIONS` environment variable. For Reports Server, you can use the command line to specify the JVM options. For details about JVM option support, see the Oracle Application Server Reports Services Publishing Reports to the Web manual.

## 3.2 Windows System Files (wsf.exe)

Note: Perform this procedure only if prompted by the installer.

Forms and Reports Services requires minimum versions of some system files in the Windows system directory (typically `C:\Windows\system32` or `C:\Winnt\system32`). When you run the installer for Forms and Reports Services, the installer checks the Windows system files on your computer. If it finds old versions of these files, and the files are in use by other processes, then it prompts you to exit the installer and run `wsf.exe` to install the latest Windows system files. (If it finds old versions of the files, but the files are not in use by other processes, then it just replaces the files and you do not have to run `wsf.exe`.)

`wsf.exe` is located in the same directory as the installer.

To run `wsf.exe`, which you need to do only if prompted by the installer, perform these steps:

1. Start `wsf.exe`, which starts Oracle Universal Installer to install the Windows system files.

   CD-ROM (assumes E: is the CD-ROM drive):

       E:\> wsf.exe

   DVD-ROM (assumes E: is the DVD-ROM drive):

       E:\> cd application_server
       E:\> wsf.exe

2. Follow the screens in the installer:

   Table 3-2 Screens for Installing Windows System Files

   | Screen | Action
   --- | --- | ---
   1. | Welcome | Click Next.
   2. | Specify File Locations | Destination Name: Enter a name for the Oracle home for wsf. Destination Path: Enter any full path. The installer installs the files in the proper system directories, regardless of the value you enter in this field. Click Next.
   3. | Warning: System Reboot Required | If you see this screen, the installer restarts your computer automatically at the end of this installation to complete the Windows system files installation. Save and close applications (other than this installer) that you have running on your computer. Click Next.
   4. | Summary | Click Next to start installing the Windows system files.
   5. | End of Installation | Click Exit to exit the installer.

3. If the installer displayed the Warning: System Reboot Required screen during installation, the installer now restarts your computer. If not, restart your computer before continuing.

## 3.3 Ports

Many Oracle Application Server components, such as Oracle HTTP Server, OracleAS Web Cache, and Oracle Enterprise Manager 10g, use ports. You can have the installer assign default port numbers, or use port numbers that you specify.

- Section 3.3.1, "About Ephemeral Ports"

- Section 3.3.2, "Checking If a Port Is in Use"

- Section 3.3.3, "Using Default Port Numbers"

- Section 3.3.4, "Using Custom Port Numbers (the Static Ports Feature)"

### 3.3.1 About Ephemeral Ports

Problem: Components Cannot Start Up Because of Conflicts with Ephemeral Ports

On rare occasions, Oracle Application Server processes are unable to start because required ports are not available. Processes may fail to start or report that they are unable to bind to ports. The behavior may be transient in that if you try to restart the affected process later, it does start successfully.

The cause of this problem is that by default, Oracle Application Server uses a number of ports that fall into the range of ephemeral ports. Ephemeral ports are usually used on the client ends of client/server TCP/IP connections. Because client processes usually are unconcerned with the port value used on the client side of the connection, all TCP/IP implementations enable clients to defer to the operating system the choice of the port value to use for the client side. The operating system selects a port from the ephemeral port range for each client connection of this type.

On the other hand, server processes (for example, Oracle Application Server processes) cannot use ephemeral ports. They must use fixed port values so that clients can always connect to the same server port to communicate with the server.

Port conflicts with ephemeral ports arise when an Oracle Application Server process is configured to use a port in the ephemeral port range. The Oracle Application Server process tries to start up, but discovers that the port that it needs is already in use by a client process (the client received the ephemeral port assignment from the operating system). This client can be any process on the computer capable of communicating through TCP/IP. The Oracle Application Server process fails to start up when the port that it needs is unavailable.

This problem occurs relatively more frequently on Microsoft Windows than on other operating systems because by default Windows uses a small range of ports for ephemeral client connections.

Ephemeral Port Range

The ephemeral port range on Microsoft Windows is ports `1024` through `5000`, inclusive.

Only the upper end of this range is adjustable in Windows. In most other operating systems, the ephemeral range by default is much larger, and the lower and upper bounds of the range are adjustable.

Several Application Server processes, including Oracle HTTP Server, OracleAS Web Cache, Oracle Enterprise Manager 10g Application Server Control, and OC4J, use ports in the ephemeral port range. These processes cannot start up if the ports that they need are already in use by clients.

Avoiding Conflicts with Ephemeral Ports

To avoid conflicts with ephemeral ports, you have these options:

- Install Forms and Reports Services using `staticports.ini` so that Forms and Reports Services components do not use ports within the ephemeral range. In the `staticports.ini` file, use port numbers below 1024 or above 5000.

  See Section 3.3.4, "Using Custom Port Numbers (the Static Ports Feature)" for details.

- If you have already installed Forms and Reports Services, you can reconfigure the components to use ports below 1024 or above 5000. See the Oracle Application Server Administrator's Guide to learn to change the current ports used by Application Server processes.

- (This option can be done post-installation.) Modify the ephemeral port range on your computer. Use this option only if you cannot use any of the alternatives above. This option is the least preferred because it makes changes to the Windows registry, and it affects all products that you run on your computer.

  This option moves the ephemeral port range to a new location. Before making the change, you must verify that none of the products you are using (Oracle or non-Oracle) on your computer use non-ephemeral ports within the ephemeral port range. If any products do so, you must relocate them to the new ReservedPorts range (see below), above the new ephemeral range, or below port `1024`.

  To implement this option, perform these steps:

  - Raise the upper bound of the ephemeral port range to expand the size of the range.

    Set the `MaxUserPort` value in the registry to at least `13000`, but no higher than `65534`. `MaxUserPort` is the upper bound of the ephemeral port range.

    For steps, see Microsoft Knowledge Base article 196271: `http://support.microsoft.com/default.aspx?scid=kb;[LN];196271`.

  - Reserve a portion of the newly expanded ephemeral port range for use by Oracle Application Server.

    Set the ReservedPorts value in the registry so that ports `1024` through `8000` are reserved for Oracle Application Server. The reserved range incorporates the range of ports normally used by Oracle Application Server.

    For steps, see Microsoft Knowledge Base article 812873: `http://support.microsoft.com/default.aspx?scid=kb;[LN];812873`.

  - Restart your computer for the changes to take effect.

  After performing the steps, you end up with the following: ports from `1024` through `8000` are reserved for Oracle Application Server, and ports `8001` through `13000` are the new ephemeral port range (assuming you set the `MaxUserPort` to `13000`). The reserved range incorporates the range of ports normally used by Oracle Application Server, and the ephemeral range has the same size as the original.

### 3.3.2 Checking If a Port Is in Use

To check if a port is being used, run the `netstat` command as follows:

    C:\> netstat -an | find "portnum"

Note that you need double-quotes around the port number.

### 3.3.3 Using Default Port Numbers

If you want to use the default port numbers for components, you do not have to do anything. Ensure that at least one port is available in the port range for each component. If the installer is unable to find a free port in the range, the installation fails.

Note the following points:

- The installer assigns the default ports to components only if the ports are not in use by other applications. If the default port is in use, the installer tries other ports in the port number range for the component. For example, the default non-SSL port for Oracle HTTP Server for the middle tier is port `80`. If this port is in use by another application, the installer assigns a port in the `7777 - 7877` range.

- The default ports for Oracle HTTP Server depend on the installation type (Table 3-3). The middle tier gets ports `80` and `443` because it is where you would deploy your applications. Users would send requests to the middle tier's Oracle HTTP Server/OracleAS Web Cache to access the applications.

  In Table 3-3, the values in parenthesis indicate the ports that the installer tries to assign to Oracle HTTP Server if the default port is already in use.

  Table 3-3 Default Ports for Oracle HTTP Server

  Installation Type | Default Non-SSL Port | Default SSL Port
  --- | --- | ---
  OracleAS Infrastructure | 7777 (7777 - 7877) | 4443 (4443 - 4543)
  Middle tier | 80 (7777 - 7877) | 443 (4443 - 4543)

- The installer no longer checks the `services` file to determine if a port is in use. In earlier releases, the installer would not assign a port number if the port number was listed in the file.

  The `services` file is located in the `C:\``%SystemRoot%``\system32\drivers\etc` directory, where `%SystemRoot%` is `winnt` on Windows 2000, and `windows` on Windows XP and Windows 2003.

### 3.3.4 Using Custom Port Numbers (the Static Ports Feature)

To instruct the installer to assign custom port numbers for components:

1. Create a file containing the component names and port numbers. Section 3.3.4.1, "Format of the staticports.ini File" describes the file format. This file is typically called `staticports.ini`, but you can name it anything you want.

2. In the installer, on the Specify Port Configuration Options screen, select Manual and enter the complete path to the `staticports.ini` file.

   If you do not specify the complete path to the file, the installer will not be able to find the file. The installer then assigns default ports for all the components, and it does this without displaying any warning.

Difference from Previous Release: In Release 10g (9.0.4), you used command-line options to specify the `staticports.ini` file. In this release, you specify the file in the new Specify Port Configuration Options screen.

#### 3.3.4.1 Format of the staticports.ini File

The `staticports.ini` file has the following format. Replace `port_num` with the port number that you want to use for the component.

    # J2EE and Web Cache
    Oracle HTTP Server port = port_num
    Oracle HTTP Server Listen port = port_num
    Oracle HTTP Server SSL port = port_num
    Oracle HTTP Server Listen (SSL) port = port_num
    Oracle HTTP Server Diagnostic port = port_num
    Java Object Cache port = port_num
    DCM Java Object Cache port = port_num
    DCM Discovery port = port_num
    Oracle Notification Server Request port = port_num
    Oracle Notification Server Local port = port_num
    Oracle Notification Server Remote port = port_num
    Application Server Control port = port_num
    Application Server Control RMI port = port_num
    Oracle Management Agent port = port_num
    Web Cache HTTP Listen port = port_num
    Web Cache HTTP Listen (SSL) port = port_num
    Web Cache Administration port = port_num
    Web Cache Invalidation port = port_num
    Web Cache Statistics port = port_num
    Log Loader port = port_num
    ASG port = port_num

    # Business Intelligence and Forms
    Reports Services SQL*Net port = port_num
    Reports Services discoveryService port = port_num
    Reports Services bridge port = port_num

    # Infrastructure
    Oracle Internet Directory port = port_num
    Oracle Internet Directory (SSL) port = port_num
    Oracle Certificate Authority SSL Server Authentication port = port_num
    Oracle Certificate Authority SSL Mutual Authentication port = port_num
    Ultra Search HTTP port number = port_num

The easiest way to create the file is to use the `staticports.ini` file on the CD-ROM (Disk 1) or DVD-ROM as a template:

1. Copy the `staticports.ini` file from the CD-ROM or DVD-ROM to your hard disk.

   Table 3-4 Location of the staticports.ini File on CD-ROM and DVD-ROM

   Media | Location of staticports.ini File (assumes E: is your CD-ROM or DVD-ROM drive)
   --- | ---
   CD-ROM | Disk 1: `E:\stage\Response\staticports.ini`
   DVD-ROM | `E:\application_server\stage\Response\staticports.ini`

2. Edit the local copy (the file on the hard disk) to include the required port numbers.

   You do not need to specify port numbers for all components in the `staticports.ini` file. If a component is not listed in the file, the installer uses the default port number for that component.

   The following example sets the Application Server Control port and some OracleAS Web Cache ports. For components not specified, the installer assigns the default port numbers.

       Application Server Control port = 2000
       Web Cache Administration port = 2001
       Web Cache Invalidation port = 2002
       Web Cache Statistics port = 2003

   When installation is complete, you can check the `portlist.ini` file to see the assigned ports.

Notes on Choosing Port Numbers: Port numbers cannot be greater than `65535`. If you plan to set port numbers for Oracle HTTP Server and OracleAS Web Cache, be sure you read Section 3.3.4.3, "Ports for Oracle HTTP Server and OracleAS Web Cache".

The installer verifies that the ports specified in the file are available by checking the memory. This means that it can only detect ports that are being used by running processes. It does not look in configuration files to determine which ports an application is using.

If the installer detects that a specified port is not available, it displays an alert. The installer does not assign a port that is not available. To fix this:

1. Edit the `staticports.ini` file to specify a different port, or shut down the application using the port.

2. Click Retry. The installer rereads the `staticports.ini` file and verifies the entries in the file again.

Using portlist.ini as the staticports.ini File

The `staticports.ini` file uses the same format as the `portlist.ini` file, which is created after a Forms and Reports Services installation. If you have installed Forms and Reports Services and want to use the same port numbers in another installation, use the `portlist.ini` file from the first installation as the `staticports.ini` file for subsequent installations.

Note: In `staticports.ini`, the `Oracle Management Agent port` line corresponds to the `Enterprise Manager Agent port` line in `portlist.ini`.

#### 3.3.4.2 Error Conditions That Cause the Installer to Use Default Ports Instead of Specified Ports

Check the `staticports.ini` file carefully because a mistake can cause the installer to use default ports without displaying any warning. Here are some things that you should check:

- If you specify the same port for more than one component, the installer uses the specified port for the first component, but for the other components, it uses the components' default ports. The installer does not warn you if you have specified the same port for multiple components.

- If you have syntax errors in the `staticports.ini` file (for example, if you omitted the `=` character for a line), the installer ignores the line. For the components specified on such lines, the installer assigns the default ports. The installer does not display a warning for lines with syntax errors.

- If you misspell a component name, the installer assigns the default port for the component. Names of components in the file are case-sensitive. The installer does not display a warning for lines with unrecognized names.

- If you specify a non-numeric value for the port number, the installer ignores the line and assigns the default port number for the component. It does this without displaying any warning.

- If you specify a relative path to the `staticports.ini` file, the installer will not find the file. The installer continues without displaying a warning and assigns default ports to all components. You must specify a complete path to the `staticports.ini` file.

#### 3.3.4.3 Ports for Oracle HTTP Server and OracleAS Web Cache

In the `httpd.conf` file for Oracle HTTP Server, the `Port` and the `Listen` directives specify the ports used by OracleAS Web Cache and Oracle HTTP Server. The correct lines in the `staticports.ini` file for setting these ports depend on the components that you are configuring.

Ensure that you understand the following when setting ports for these components.

If You Are Configuring OracleAS Web Cache and Oracle HTTP Server

1. Set the port for OracleAS Web Cache.

   OracleAS Web Cache uses the port specified by the `Port` directive (Figure 3-1). To set this port, use this line in the `staticports.ini` file:

       Web Cache HTTP Listen port = port_number

   To configure the SSL port for OracleAS Web Cache, use the following line:

       Web Cache HTTP Listen (SSL) port = port_number

   You cannot set the port number using the `Oracle HTTP Server port` line in this case. If the `staticports.ini` file contains both the `Oracle HTTP Server port` and the `Web Cache HTTP Listen port` lines, the `Oracle HTTP Server port` line is ignored. For example, if you have these lines in `staticports.ini`:

       Web Cache HTTP Listen port = 7979
       Oracle HTTP Server port = 8080

   the `Port` directive is set to `7979`.

2. Set the port for Oracle HTTP Server.

   Oracle HTTP Server uses the port specified by the `Listen` directive. To set this port, use this line in the `staticports.ini` file:

       Oracle HTTP Server Listen port = port_number

   To configure the SSL Listen port, use the following line:

       Oracle HTTP Server Listen (SSL) port = port_number

Figure 3-1 Configuring Both OracleAS Web Cache and Oracle HTTP Server

Description of "Figure 3-1 Configuring Both OracleAS Web Cache and Oracle HTTP Server"

If You Are Configuring Oracle HTTP Server Only (no OracleAS Web Cache)

If you are configuring Oracle HTTP Server only, then Oracle HTTP Server uses both `Port` and `Listen` directives (Figure 3-2). In this case, you must set both directives to use the same port number.

To set these ports, use the `Oracle HTTP Server port` and `Oracle HTTP Server Listen port` lines in the `staticports.ini` file. For example:

    Oracle HTTP Server port = 8080
    Oracle HTTP Server Listen port = 8080

To set the SSL version of these ports, use the following lines. As in the non-SSL version, the port numbers must be the same.

    Oracle HTTP Server SSL port = 443
    Oracle HTTP Server Listen (SSL) port = 443

If you also specify the Web Cache lines in `staticports.ini`, they are ignored because you are not configuring OracleAS Web Cache.

Description of "Figure 3-2 Configuring Only Oracle HTTP Server"

## 3.4 Operating System User

The operating system user performing the installation must belong to the Administrators group. Perform the following steps to check if the operating system user belongs to the Administrators group.

To check if a user belongs to the administrators group:

1. Display the Computer Management dialog box.

   Windows 2000 / Windows XP: Right-click My Computer on the desktop, and click Manage.

   Windows 2003: Right-click the local computer icon on the desktop, and click Manage.

2. On the left side, expand Local Users and Groups, and select Users.

3. On the right side, right-click the user and click Properties to display the Properties dialog box.

4. Select the Member Of tab.

If you are not a member of the Administrators group, get an administrator to add you to the group or log in as a user who is a member of the Administrators group.

## 3.5 Environment Variables

The operating system user who installs Forms and Reports Services must set (or unset) the environment variables listed in Table 3-5.

Table 3-5 Environment Variable Summary

Environment variable | Set or Unset
--- | ---
ORACLE_HOME and ORACLE_SID | Does not matter (the installer unsets these two environment variables).
PATH | Must not be longer than 1023 characters.
TNS_ADMIN | Must not be set.
TEMP | Optional. If unset, defaults to `C:\temp`.

### 3.5.1 Setting Environment Variables

To set environment variables in Windows:

1. Display the System control panel.

   Windows 2000: Select Start > Settings > Control Panel > System.

   Windows 2003: Select Start > Control Panel> System.

   Windows XP: Select Start > Control Panel, and then double-click System.

2. Click the Advanced tab.

3. Click Environment Variables.

4. To change the value of a variable, select the variable and click Edit.

### 3.5.2 ORACLE_HOME and ORACLE_SID

The installer unsets the `ORACLE_HOME` and `ORACLE_SID` environment variables when you start the installer regardless of whether these environment variables were set or unset.

### 3.5.3 PATH and CLASSPATH

The PATH environment variable cannot be longer than 1023 characters. Otherwise, the installation may fail.

### 3.5.4 TEMP

During installation, the installer needs to write temporary files to a temporary directory. By default, the temporary directory is `C:\temp`.

If you want the installer to use a directory other than `C:\temp`, set the `TEMP` environment variable to the full path of an alternate directory. This directory must meet the requirements listed in Table 3-1.

If you do not set this environment variable, and the default directory does not have enough space, then the installer displays an error message that says the environment variable is not set. You can either set the environment variable to point to a different directory or free up enough space in the default directory. In either case, you have to restart the installation.

## 3.6 The Hosts File

The hosts file for Windows is located at `%WINDIR%` `\system32\drivers\etc\`, where %WINDIR% specifies the Windows operating system directory. Typically, it is `C:\WINDOWS` for Windows 2003, and `C:\WINNT` for Windows 2000.

The contents of the `%WINDIR%\system32\drivers\etc\hosts` file affect the location of the default Oracle Identity Management realm and the host name for Oracle Application Server Single Sign-On.

The installer provides alternative methods for you to enter the values that you want without editing the `hosts` file. For more information, see the Oracle Application Server Installation Guide.

## 3.7 Network Topics

Typically, the computer on which you want to install Forms and Reports Services is connected to the network, has local storage to contain the Forms and Reports Services installation, has a display monitor, and has a CD-ROM or DVD-ROM drive.

This section describes the procedure to install Forms and Reports Services on computers that do not meet the typical scenario. It covers the following cases:

- Installing on DHCP Computers

- Installing on Multihomed (Multi-IP) Computers

- Installing on Computers With Multiple Aliases

- Installing on Non-Networked Computers

- Installing on Static IP Computers That You Want to Disconnect from the Network Later

- Installing a Loopback Adapter

- Copying CD-ROMs or DVD-ROM to Hard Drive, and Installing from the Hard Drive

- Installing from a Remote CD-ROM or DVD-ROM Drive

- Installing on Remote Computers

### 3.7.1 Installing on DHCP Computers

Note this limitation when running Forms and Reports Services on DHCP computers: Forms and Reports Services instances on DHCP computers cannot communicate with instances running on other computers. All the instances that need to communicate with each other must run on the same computer. There are no limitations on clients; clients from other computers can access instances running on the DHCP computer, as long as the client computer can resolve the DHCP computer on the network.

Before installing Forms and Reports Services on a DHCP computer, perform these steps:

1. Install a loopback adapter on the DHCP computer.

   When you install a loopback adapter, the loopback adapter assigns a local IP for your computer. Having a loopback adapter and a local IP address means that you do not have to run the `chgiphost` script after installation each time the IP address changes (due to DHCP).

   Which Is the Primary Network Adapter?

   Windows considers loopback adapters as a type of network adapter. After installing a loopback adapter on your computer, you have at least two network adapters on your computer: your network adapter and the loopback adapter.

   Windows must use the loopback adapter as the primary adapter. The primary adapter is determined by the order in which you installed the adapters:

   - On Windows 2000, the primary adapter is the last adapter installed. You can just install the loopback adapter. However, if you install additional network adapters after installing the loopback adapter, deinstall the loopback adapter and reinstall it.

   To install a loopback adapter on the different Windows platforms, see Section 3.7.6, "Installing a Loopback Adapter".

2. Ping each computer on which you plan to install Forms and Reports Services.

   - Ping the computer from itself, using only the hostname and the fully qualified name.

     For example, if you installed a loopback adapter on a computer called `mycomputer`, check the following:

         prompt> ping mycomputer                Ping itself using just the hostname.
         Reply from 10.10.10.10                    Returns local IP.
         prompt> ping mycomputer.mydomain.com   Ping using a fully qualified name.
         Reply from 10.10.10.10                    Returns local IP.

     Note: When you ping a computer from itself, the `ping` command should return the local IP (the IP of the loopback adapter). It should not return the network IP of the computer.

   - Ping the computer from other computers on the network, using only the hostname and the fully qualified name.

     In this case, the `ping` command returns the network IP of the computer.

         prompt> ping mycomputer                Ping using the hostname.
         Reply from 139.185.140.166                Returns network IP.
         prompt> ping mycomputer.mydomain.com   Ping using a fully qualified name.
         Reply from 139.185.140.166                Returns network IP.

   If `ping` fails, then contact your network administrator.

### 3.7.2 Installing on Multihomed (Multi-IP) Computers

A multihomed computer is associated with multiple IP addresses. This is achieved by having multiple network cards on the computer. Each IP address is associated with a hostname; additionally, you can set up aliases for the hostname. By default, Oracle Universal Installer uses the `ORACLE_HOSTNAME` environment variable setting to find the hostname. If `ORACLE_HOSTNAME` is not set and you are installing Forms and Reports Services on a computer that has multiple network cards, Oracle Universal Installer determines the hostname by using the first name in the hosts file (typically located in `DRIVE_LETTER``:\WINDOWS\system32\drivers\etc`).

Clients must be able to access the computer using this hostname (or using aliases for this hostname). To check, ping the hostname from the client computers using the short name (hostname only) and the full name (hostname and domain name). Both must work.

### 3.7.3 Installing on Computers With Multiple Aliases

A computer with multiple aliases refers to a computer registered with the naming service under a single IP but with multiple aliases. The naming service resolves any of those aliases to the same computer.

Before installing Forms and Reports Services on such computers, you must:

- Install a loopback adapter on the computer.

- Ensure the loopback adapter is the primary network adapter.

The loopback adapter ensures that when Forms and Reports Services queries for the hostname, it always gets the same name (because the queries are done locally). Without the loopback adapter, the queries can return any of the aliases for the computer (because the queries get the response from the naming service).

For steps on installing a loopback adapter, see Section 3.7.6, "Installing a Loopback Adapter".

### 3.7.4 Installing on Non-Networked Computers

You can install Forms and Reports Services on a non-networked computer, such as a laptop. Because a non-networked computer has no access to other computers, you must install all the components that you need on the computer.

If you want to install Forms and Reports Services on a non-networked computer and do not want to connect the computer to a network after installation, then install Forms and Reports Services on your non-networked computer.

Note: If you are installing on a non-networked computer, then configure the Common Object Service (COS) naming service to access the Reports Server. For information about configuring the naming service, see the Oracle Application Server Reports Services Publishing Reports to the Web manual.

However, if you want to connect the computer to a network after installation, perform these steps before installing Forms and Reports Services on the non-networked computer.

1. Install a loopback adapter on the computer. See Section 3.7.6, "Installing a Loopback Adapter".

   The loopback adapter and local IP address simulate a networked computer. If you connect the computer to the network, Forms and Reports Services uses the local IP and hostname.

2. Ping the computer from itself, using only the hostname and the fully qualified name.

   For example, if you installed a loopback adapter on a computer called `mycomputer`, check the following:

       prompt> ping mycomputer                Ping itself using just the hostname.
       Reply from 10.10.10.10                    Returns local IP.
       prompt> ping mycomputer.mydomain.com   Ping using a fully qualified name.
       Reply from 10.10.10.10                    Returns local IP.

   Note: When you ping a computer from itself, the `ping` command should return the local IP (the IP of the loopback adapter).

   If `ping` fails, then contact your network administrator.

Connecting the Computer to the Network After Installation

If you connect the computer to a network after installation, then the Forms and Reports Services instance on your computer can work with other instances on the network. Recall that you must have installed a loopback adapter on your computer. Your computer can use a static IP or DHCP, depending on the network to which you are connected.

See the Oracle Application Server Administrator's Guide for details.

### 3.7.5 Installing on Static IP Computers That You Want to Disconnect from the Network Later

If you plan to install Forms and Reports Services on a networked computer with static IP and be able to run Forms and Reports Services when you disconnect the computer from the network, perform the following steps before installing Forms and Reports Services:

1. Install a loopback adapter on your computer. See Section 3.7.6, "Installing a Loopback Adapter" for details.

   Without a loopback adapter, Forms and Reports Services cannot function correctly when you disconnect the computer from the network because the static IP is no longer available.

2. Ensure the loopback adapter is the primary network adapter. To check, `ping` the computer from itself using (1) the hostname only and (2) the fully qualified name.

   For example, if you installed a loopback adapter on a computer called `mycomputer`, you can run these commands:

       prompt> ping mycomputer                Ping itself using just the hostname.
       Reply from 10.10.10.10                    Returns loopback adapter IP.
       prompt> ping mycomputer.mydomain.com   Ping using a fully qualified name.
       Reply from 10.10.10.10                    Returns loopback adapter IP.

   When you ping a computer from itself, the `ping` command should return the IP of the loopback adapter. It should not return the network IP of the computer.

These steps are required regardless of whether the computer is using static IP or DHCP. If this is a DHCP computer, you already know you need a loopback adapter; see Section 3.7.1, "Installing on DHCP Computers".

When you disconnect the computer from the network, the computer has no access to any network resources.

### 3.7.6 Installing a Loopback Adapter

A loopback adapter is required if:

- You are installing on a DHCP computer (see Section 3.7.1, "Installing on DHCP Computers").

- You are installing on a non-networked computer and plan to connect the computer to a network after installation (see Section 3.7.4, "Installing on Non-Networked Computers").

The procedure for installing a loopback adapter depends on the version of Windows:

- Section 3.7.6.1, "Checking If a Loopback Adapter Is Installed on Your Computer"

- Section 3.7.6.2, "Installing a Loopback Adapter - Windows 2000"

- Section 3.7.6.3, "Installing a Loopback Adapter - Windows 2003 / Windows XP"

- Section 3.7.6.4, "Removing a Loopback Adapter - Windows 2000 / Windows 2003 / Windows XP"

#### 3.7.6.1 Checking If a Loopback Adapter Is Installed on Your Computer

To check if a loopback adapter is installed on your computer, run the `ipconfig /all` command:

    prompt> ipconfig /all

If there is a loopback adapter installed, you will see a section that lists the values for the loopback adapter. For example:

    Ethernet adapter Local Area Connection 2:
      Connection-specific DNS Suffix  . :
      Description . . . . . . . . . . . : Microsoft Loopback Adapter
      Physical Address. . . . . . . . . : 02-00-4C-4F-4F-50

      Autoconfiguration IP Address. . . : 169.254.25.129
      Subnet Mask . . . . . . . . . . . : 255.255.0.0

#### 3.7.6.2 Installing a Loopback Adapter - Windows 2000

Windows 2000 reports on the last network adapter installed. This means that if you install additional network adapters after installing the loopback adapter, remove and reinstall the loopback adapter. The loopback adapter must be the last network adapter installed on the computer.

### 3.7.7 Copying CD-ROMs or DVD-ROM to Hard Drive, and Installing from the Hard Drive

Instead of installing from the Forms and Reports Services CD-ROMs or DVD-ROM, you can copy the contents of the CD-ROMs or DVD-ROM to a hard drive and install from the hard drive. This might be easier if you plan to install many instances of Forms and Reports Services on your network, or if the computers on which you want to install Forms and Reports Services do not have CD-ROM or DVD-ROM drives.

You can also install from remote CD-ROM or DVD-ROM drives. See Installing from a Remote CD-ROM or DVD-ROM Drive.

When you install from the hard drive, the installer does not prompt you to swap CD-ROMs. It can find all the files if they are in the proper locations.

Accessing the Hard Drive from Other Computers

If you want to install Forms and Reports Services on remote computers from the hard drive where you copied the contents of the CD-ROM or DVD-ROM, perform the following steps:

1. On the local computer, share the hard drive.

2. On the computers where you want to install Forms and Reports Services, map to the shared hard drive.

3. Run the installer from the remote computers on which you want to install Forms and Reports Services.

   Note that you have to use the drive letter for the mapped drive to access the installer (for example, `H:\orawinfrs_10_1_2\setup.exe`).

   You cannot use the universal naming convention (UNC) syntax (`\\``hostname``\``sharename`) to access the installer.

To copy the CD-ROMs:

1. Create a parent directory (for example, `orawinfrs`) and, under the parent directory, create subdirectories called `Disk1`, `Disk2`, and so on. The names of the subdirectories must be `Disk` `N`, where `N` is the CD-ROM number.

2. Copy the contents of each CD-ROM into the corresponding directory.

   You can copy the files using Windows Explorer or the command line. If you are using the command line, you can use the `xcopy` command.

   The following example assumes E: is the CD-ROM drive, and `C:\orawinfrs\Disk` `N` are the directories that you want to copy the CD-ROMs to.

       E:\> xcopy /e /i  E:\1012disk1  C:\orawinfrs\Disk1
       E:\> xcopy /e /i  E:\1012disk2  C:\orawinfrs\Disk2
       ... Repeat for each CD-ROM.

To run the installer from the copied files, invoke the `setup.exe` executable from the `Disk1` directory. Run it from the computer that will be running Forms and Reports Services.

    C:\> cd orawinfrs\Disk1
    C:\orawinfrs\Disk1> setup.exe

To copy the orawinfrs Directory from the DVD-ROM

You can copy the `orawinfrs` directory using Windows Explorer or the command line. If you are using the command line, here are the steps:

1. (optional) Create a directory to contain the `orawinfrs` directory.

2. Copy the `orawinfrs` directory from the DVD-ROM to your hard disk.

   The example assumes `E:` is the DVD-ROM drive, and `C:\orawinfrs` is the destination directory:

       E:\> xcopy /e /i  E:\orawinfrs C:\orawinfrs

To run the installer from the copied files, invoke the `setup.exe` executable from the computer that will be running Forms and Reports Services:

    C:\> cd orawinfrs
    C:\orawinfrs> setup.exe

### 3.7.8 Installing from a Remote CD-ROM or DVD-ROM Drive

If the computer on which you want to install Forms and Reports Services does not have a CD-ROM or DVD-ROM drive, you can perform the installation from a remote CD-ROM or DVD-ROM drive. Check that you have performed these steps:

On the Remote Computer, Share the CD-ROM or DVD-ROM Drive

The remote CD-ROM or DVD-ROM drive that you want to use must allow shared access. To set this up, perform these steps on the remote computer (the computer that has the CD-ROM or DVD-ROM drive):

1. Log on to the remote computer as an Administrator user.

2. Start up Windows Explorer.

3. Right-click the CD-ROM or DVD-ROM drive letter and choose Sharing (Windows 2000) or Sharing and Security (Windows 2003, Windows XP).

4. On the Sharing tab (Figure 3-7):

   Select Share this folder.

   Share name: Give it a share name such as `cdrom` or `dvd`. You will use this name when you map the CD-ROM or DVD-ROM drive on the local computer.

   Click Permissions. The user who accesses this folder to install Forms and Reports Services will need at least read permission.

   Click OK when done.

   Figure 3-7 Sharing a CD-ROM Drive

   Description of "Figure 3-7 Sharing a CD-ROM Drive"

5. CD-ROM: Insert Forms and Reports Services Disk 1 into the CD-ROM drive.

   DVD-ROM: Insert the Forms and Reports Services DVD into the DVD-ROM drive.

On the Local Computer, Map the CD-ROM or DVD-ROM Drive

Perform these steps on the local computer to map the CD-ROM or DVD-ROM drive and to run the installer:

1. Map the remote CD-ROM or DVD-ROM drive.

   1. Start up Windows Explorer on the local computer.

   2. Select Tools > Map Network Drive. This displays the Map Network Drive dialog box.

   3. Select a drive letter to use for the remote CD-ROM or DVD-ROM drive.

   4. In Folder, enter the location of the remote CD-ROM or DVD-ROM drive using the following format:

          \\remote_hostname\share_name

      Replace `remote_hostname` with the name of the remote computer with the CD-ROM or DVD-ROM drive.

      Replace `share_name` with the share name that you entered.

      Example: `\\computer2\cdrom`

   5. If you need to connect to the remote computer as a different user, click Different User Name, and enter the username.

   6. Click Finish.

2. Run the installer from the mapped CD-ROM or DVD-ROM drive.

   When the installer prompts you to switch CD-ROMs, eject the CD-ROM and insert the requested CD-ROM.

   Note: The installer must be running when you are switching CD-ROMs. Do not exit the installer when switching CD-ROMs. If you exit the installer, it is unable to continue from where it left off. In addition, the partial installation created is not usable and may need to be removed manually.

### 3.7.9 Installing on Remote Computers

If you want to install and run Forms and Reports Services on a remote computer (that is, the remote computer has the hard drive and will run Forms and Reports Services components), but you do not have physical access to the computer, you can still perform the installation on the remote computer if it is running remote control software such as VNC or Symantec pcAnywhere. You also need the remote control software running on your local computer.

You can install Forms and Reports Services on the remote computer in one of these two ways:

- If you have copied the contents of the Forms and Reports Services CD-ROM or DVD-ROM to a hard drive, then you can install from the hard drive.

- You can insert the CD-ROM or DVD-ROM into a drive on your local computer, and install from the CD-ROM or DVD-ROM.

Installing from a Hard Drive

If you have copied the contents of the Forms and Reports Services CD-ROM or DVD-ROM to a hard drive, then you can install from the hard drive. To install from the hard drive:

1. Ensure that the remote control software is installed and running on the remote and local computers.

2. Share the hard drive that contains the Forms and Reports Services CD-ROM or DVD-ROM.

3. On the remote computer, map a drive letter to the shared hard drive. Use the remote control software to do this on the remote computer.

4. Using the remote control software, run the installer on the remote computer. You can access the installer from the shared hard drive.

Installing from a Remote CD-ROM or DVD-ROM Drive

You can insert the CD-ROM or DVD-ROM into a drive on your local computer, and install from the CD-ROM or DVD-ROM. This is similar to the scenario described in Section 3.7.8, "Installing from a Remote CD-ROM or DVD-ROM Drive". To install from a remote CD-ROM or DVD-ROM:

1. Ensure that the remote control software is installed and running on the remote and local computers.

2. On the local computer, share the CD-ROM or DVD-ROM drive.

   On the remote computer, map a drive letter to the shared CD-ROM or DVD-ROM drive. Use the remote control software to do this on the remote computer.

   These steps are described in Section 3.7.8, "Installing from a Remote CD-ROM or DVD-ROM Drive".

3. Using the remote control software, run the installer on the remote computer. You can access the installer from the shared CD-ROM or DVD-ROM drive.
