2 Installing Oracle WebCenter

2.1.1 System Requirements and Certification

Before performing any installation you should read the system requirements and certification documentation to ensure that your environment meets the minimum installation requirements for the products you are installing. Both of these documents are available on Oracle Technology Network (OTN).

The system requirements document covers information such as hardware and software requirements, minimum disk space and memory requirements, and required system libraries, packages, or patches:

http://www.oracle.com/technology/software/products/ias/files/fusion_requirements.htm

The certification document covers supported installation types, platforms, operating systems, databases, JDKs, and third-party products:

http://www.oracle.com/technology/software/products/ias/files/fusion_certification.html

2.1.2 Check for Supported Database

Installation of Oracle WebCenter requires the availability of a database. This database must be up and running, and does not have to be on the same system where you are installing the products.

For the latest information about supported databases, visit the following URL:

http://www.oracle.com/technology/software/products/ias/files/fusion_certification.html

2.1.3 Create Schemas for Oracle WebCenter

Oracle WebCenter requires that certain schemas exist in the database prior to installation. You must run Repository Creation Utility (RCU) to create the schemas in the database. Follow these instructions to do so:

1. Insert the RCU CD-ROM and start RCU from the rcuHome/bin (on UNIX operating systems) or rcuHome\bin (on Windows operating systems) directory:

   On UNIX operating systems:

   ./rcu
   

   On Windows operating systems:

   rcu.bat
   

   You can also download a .zip file containing RCU from Oracle Technology Network (OTN):

   http://www.oracle.com/technology/
   

   After downloading the .zip file, extract the contents to a directory of your choice, and run RCU from the RCU_HOME/bin (on UNIX operating systems) or RCU_HOME\bin (on Windows operating systems) directory with the commands shown above, where RCU_HOME is the folder where RCU was unzipped, or the drive or mount point of the CD-ROM.

   Note:

   On Windows systems, make sure that you do not extract the RCU .zip file to a directory name containing spaces.

2. Welcome Screen

   Click Next.

3. Create Repository Screen

   Select Create.

   Click Next.

4. Database Connection Details Screen

   Provide the necessary credentials for RCU to be able to connect to your Oracle database:

   • Host Name: Specify the name of the machine on which your database resides in the format host.domain.com. For Oracle RAC databases, specify the Virtual IP name or one of the node names as the host name.

   • Port: Specify the database listener port number. The default port number for Oracle databases is 1521.

   • Database Name: Specify the service name for the database. Typically, the service name is the same as the global database name.

     If you are unsure what the service name for your database is, you can obtain it from the SERVICE_NAMES parameter in the database's initialization parameter file. If the initialization parameter file does not contain the SERVICE_NAMES parameter, then the service name is the same as the global database name, which is specified in the DB_NAME and DB_DOMAIN parameters.

     For Oracle RAC databases, specify the service name of one of the nodes in this field. For example: sales.mydomain.com.

   • Username: Specify the name of a user with DBA or SYSDBA privileges. The default user name with SYSDBA privileges is SYS.

   • Password: Specify the password for your database user.

   • Role: Select the database user's role from the drop-down list. The SYS user requires the SYSDBA role.

   If you are using a Microsoft SQL Server database, provide the following credentials:

   • Unicode Support: Select Yes or No from the drop-down list.

   • Server Name: Enter the host name, IP address, or complete server name in host\server format of the server where your database is running..

   • Port: Specify the database listener port number.

   • Database Name: Specify the name of your database.

   • Username: Specify the name of a user with DBA or SYSDBA privileges.

   • Password: Specify the password for your database user.

   Click Next. A "Checking Prerequisites" screen will appear. After the checking is complete with no errors, click OK to dismiss the screen.

5. Select Components Screen

   Near the top of the screen, select Create a New Prefix. If you are the only user of the database instance, you may use the default prefix DEV. If you are sharing the database instance with other Oracle Fusion Middleware users, refer to Oracle Fusion Middleware Repository Creation Utility User's Guide for more information about prefixes.

   Click the plus sign (+) icon next to WebCenter Suite to view all the schemas in this category. Select the necessary schemas for the product(s) you want to install. If the schema has dependencies, the dependencies are automatically selected for you (see Table 2-1).

   Note:

   You must remember or make a note of these schema names and the prefix value from this screen; you will need them later when you are configuring your products. You will need to provide the schema name in the format prefix_schemaname. For example, if you used the default prefix DEV, you will supply the following schema name for the MDS schema:

   DEV_MDS

   Table 2-1 Required Schemas for Oracle WebCenter Components

   Component	Schema Owner	Selected Schemas (Dependencies)
   WebCenter Spaces	WEBCENTER	prefix_MDS (Metadata Services)
   Portlet Producers	PORTLET	None.
   Discussions	DISCUSSIONS	None.
   Discussions Crawler	DISCUSSIONS_CRAWLER	prefix_DISCUSSIONS (Oracle Discussions)
   Wiki and Blogs	WIKI	None.
   Oracle Content Server 10g	OCSERVER	None.

   
   

   If you need a schema for your custom WebCenter application, create a few schema using the WebCenter Spaces prefix_WEBCENTER schema as a template (for example, if the schema DEV_WEBCENTER already exists in your database, you can create a new schema called CUST_WEBCENTER).

   Click Next. A "Checking Prerequisites" screen will appear. After the checking is complete with no errors, click OK to dismiss the screen.

6. Schema Passwords Screen

   There are three ways to specify schema passwords on this screen:

   • Select Use same password for all schemas if you want to use a single password for all schemas and their auxiliary schemas. In the Password field, enter your password. Enter your password again in the Confirm Password field.

   • Select Use main schema passwords for auxiliary schemas if you want to specify different passwords for the main schemas, but still have the same password used for their respective auxiliary schemas. If you select this option, only the main schemas will be visible in the table. For each schema, you must enter each schema's password in the Password column in the table, and enter the same password in the Confirm Password column.

   • Select Specify different passwords for all schemas if you want to specify unique passwords for the main schemas and auxiliary schemas. If you select this option, all main schemas and auxiliary schemas will be visible in the table. For each schema and auxiliary schema, you must enter the password in the Password column in the table, and enter the same password in the Confirm Password column.

   Note:

   You must remember or make a note of the password(s) from this screen; you will need them later when you are configuring your products.

   Click Next.

7. Map Tablespaces Screen

   Click Next. A "Creating Tablespaces" screen will appear. After the tablespaces are created with no errors, click OK to dismiss the screen.

8. Summary Screen

   Click Create. A "CREATE" screen will appear. After the schemas are created with no errors, click OK to dismiss the screen.

9. Completion Summary Screen

   Click Close.

For detailed information about using RCU, refer to Oracle Fusion Middleware Repository Creation Utility User's Guide.

2.1.4 Install Oracle WebLogic Server and Create the Middleware Home

Oracle WebCenter requires an Oracle WebLogic Server on your system. If you do not already have one, follow the instructions in this section to install Oracle WebLogic Server.

1. Insert the Oracle WebLogic Server CD-ROM or download the installer from the following URL:

   http://www.oracle.com/technology/software/products/ias/htdocs/wls_main.html 
   

   You are looking for the following executable files:

   • wls1032_linux32.bin (for 32-bit Linux systems)

   • wls1032_win32.exe (for 32-bit Windows systems)

   • wls1032_generic.jar (for all 64-bit platforms)

   The 32-bit executable files are bundled with the appropriate JDK version. If you use the 64-bit installer, you will need to invoke the installer with a supported JDK for your platform. This JDK must be installed on your system before you install Oracle WebLogic Server. Refer to the Oracle Fusion Middleware certification document for a list of supported JDKs for your platform:

   http://www.oracle.com/technology/software/products/ias/files/fusion_certification.html
   

2. Run your installer file directly from the CD-ROM, or copy the file to your local system and run it locally.

   Some notes for running the installer:

   • Before running the installer, set the DISPLAY environment variable on your system.

   • Replace JAVA_HOME with the installation location of the supported JDK you installed for your platform.

   • If you are installing a 64-bit Oracle WebLogic Server on a 64-bit platform, use the -d64 flag when using 32/64-bit hybrid JDK's (such as the HP JDK for HP-UX and SUN JDK for Solaris SPARC).

     Execute JAVA_HOME/bin/java -version (or JAVA_HOME/bin/java -d64 -version on 32/64-bit hybrid JDKs) to ensure that your JAVA_HOME refers to a 64-bit JDK.

   To run the installer on a 32-bit Linux operating system:

   ./wls1032_linux32.bin
   

   To run the installer on 32-bit Windows operating systems:

   wls1032_win32.exe
   

   To run the installer on 64-bit UNIX operating systems:

   JAVA_HOME/bin/java -jar wls1032_generic.jar
   

   or

   JAVA_HOME/bin/java -d64 -jar wls1032_generic.jar
   

   To run the installer on 64-bit Windows operating systems:

   JAVA_HOME\bin\java -jar wls1032_generic.jar
   

3. Welcome Screen

   Click Next.

4. Choose Middleware Home Directory Screen

   Select Create a new Middleware Home to create a new Middleware Home directory.

   Specify the desired location of your new Middleware Home directory. If this directory already exists on your system, it must be an empty directory. If this directory does not already exist, then it will be created for you.

   For more information about the Middleware Home directory, refer to "Middleware Home and WebLogic Home Directories" in Oracle Fusion Middleware Installation Planning Guide.

   Click Next.

5. Register for Security Updates Screen

   Select whether or not you want to receive the latest product and security updates. If you choose not to receive anything, you will be asked to verify your selection before continuing.

   Click Next.

6. Choose Install Type Screen

   A Typical installation includes all Oracle WebLogic Server components by default. It also includes both Sun SDK 1.6.0_14 and Oracle JRockit SDK 1.6.0_14. If you want to perform a Typical installation, select Typical and click Next to go to the Choose Product Installation Directories Screen.

   A Custom installation gives you the choice of selecting the following components for installation:

   • Core Application Server

   • Administration Console

   • Configuration Wizard and Upgrade Framework

   • Web 2.0 HTTP Pub-Sub Server

   • WebLogic JDBC Drivers

   • Third Party JDBC Drivers

   • WebLogic Server Clients

   • WebLogic Web Server Plugins

   • UDDI and Xquery Support

   • Server Examples (not selected by default)

   If you want to perform a Custom installation, select Custom. You will see the following two screens:

   1. Choose Products and Components Screen

      Select the products you want to install.

      Note:

      In order to be configured properly, Oracle WebCenter requires that Configuration Wizard and Upgrade Framework is selected.

   2. JDK Selection Screen

      Select the JDKs you want to install.

      Oracle recommends that you use the Sun SDK if you are installing in a development environment. Typically, this environment provides a more relaxed security configuration and enables you to auto-deploy applications. In a development environment, boot.properties is used for user names and passwords and polling is used for application deployment.

      If you are installing in a production environment, Oracle recommends that you use the Oracle JRockit SDK. Production environments are for applications running in their final form. Full security is enabled and applications may be clustered or use other advanced features. In this mode, user names and passwords are required and polling is not used for application deployment.

   Click Next.

7. Choose Product Installation Directories Screen

   Specify the desired location for your WebLogic Server Home directory. The default location is wlserver_10.3 inside your Middleware Home directory.

2.1.5 Install and Configure Java Access Bridge (Windows Only)

If you are installing on a Windows machine, you have the option of installing and configuring Java Access Bridge for Section 508 Accessibility. For more information on how to do this, refer to "Install and Configure Java Access Bridge (Windows Only)" in Oracle Fusion Middleware Administrator's Guide.

2.1.6 Know your HTTP Server Web Address

If you plan to install Oracle Universal Content Management (UCM) as part of the WebCenter installation, you should know your the address and port number of your HTTP server. An HTTP server is required and must be up and running if you choose to install Oracle UCM.

If your HTTP server is running in a UNIX system, you can find your HTTP server port number by opening the /etc/services file and searching for the string "HTTP."

On Windows systems, you can use the netstat command from your DOS prompt to see the ports that are being used on your system.

For more information, see Section 4.3.1.2, "Oracle Content Server - Installation".

2.3.1 For UNIX Platforms

On UNIX systems, configure the host to resolve hostnames to the loopback IP address by modifying the /etc/hosts file to contain the following entries:

127.0.0.1 hostname.domainname hostname
127.0.0.1 localhost.localdomain localhost

After doing so, check that the hostname resolves to the loopback IP address by entering the following command:

/bin/ping hostname.domainname

2.3.2 For Windows x86 Platforms

On Windows systems, install a loopback adapter on the DHCP server (see Section 2.3.3, "Installing a Loopback Adapter (Windows Only)"). This assigns a local IP address to your computer.

After installing the adapter, add a line to the %SYSTEMROOT%\system32\drivers\etc\hosts file with the following format, immediately after the localhost line:

IP_address   hostname.domainname   hostname

Replace IP_address with the local IP address of the loopback adapter.

2.8.1 Starting the Installer

The installer requires the location of a Java Runtime Environment (JRE) on your system. When you installed Oracle WebLogic Server (Section 2.1.4, "Install Oracle WebLogic Server and Create the Middleware Home"), a JRE was installed on your system. You can use this location (the location of the jre directory) to start the installer. The default location for the JRE is MW_HOME/jdk160_14_R27.6.4-18 (on UNIX systems) or MW_HOME\jdk160_14_R27.6.4-18 (on Windows systems), where MW_HOME is the Middleware Home directory.

On 64-bit platforms, the JRE location is the JAVA_HOME you used to install Oracle WebLogic Server. Refer to Section 2.1.4, "Install Oracle WebLogic Server and Create the Middleware Home" for more information.

When you provide the JRE_LOCATION you must specify an absolute path; relative paths will not work.

On UNIX operating systems:

> ./runInstaller -jreLoc JRE_LOCATION

On Windows operating systems:

D:\ setup.exe -jreLoc JRE_LOCATION

You must also specify the JRE location in the same manner if you are installing Oracle WebCenter on a 64-bit platform with a 32-bit JDK.

If no JRE location is specified, you will be prompted to provide the location of your JRE before the installer is started:

[> ./runInstaller

Specify the absolute path to the JRE on your system before you continue.

2.8.2 Installation Log Files

The installer writes logs files to the Oracle_Inventory_Location/log (on UNIX operating systems) or Oracle_Inventory_Location\logs (on Windows operating systems) directory. Refer to Section E.2.1, "Installation Log Files" for more information about the log files and their contents.

2.8.3 Inventory Screens (UNIX Only)

If you are installing on a UNIX system, and if this is the first time any Oracle product is being installed on your system with the Oracle Universal Installer, you will be asked to provide the location of an inventory directory. This is where the installer will set up subdirectories and maintain inventory data for each Oracle product that is installed on this system.

Follow the instructions in Table 2-2 to configure the inventory directory information. For more help, click on the screen name in the table below, or click the Help button in the GUI.
