1 Review Information About this Guide

This guide describes how to install Oracle Database 10g using the default installation options.

The procedures in this guide describe how to:

• Configure your system to support Oracle Database 10g

• Install the Oracle Database 10g software on a local file system

• Configure a general-purpose Oracle database that uses the local file system for database file storage

• Install software from the Oracle Database 10g Companion CD which improves the performance of Oracle Database 10g on your system

After you successfully install Oracle Database 10g:

• The database that you created and the default Oracle Net listener process are running on the system

• Oracle Enterprise Manager Database Control and iSQL*Plus are running and can be accessed using a Web browser

• A single-node version of the Oracle Cluster Synchronization Services (CSS) daemon is running and is configured to start automatically when your system boots

This guide does not describe how to complete the following tasks:

• Installing the software on a system that has an existing Oracle software installation

• Installing Oracle Cluster Ready Services (CRS) and Oracle Real Application Clusters (RAC) on a cluster

• Enabling Enterprise Manager e-mail notifications or automated backups

• Using alternative storage options such as Automatic Storage Management (ASM) or raw devices for database storage

For more detailed information about installing Oracle Database 10g, including information about the tasks not described in this guide, see one of the following guides:

• If you are installing the software on a single system, see the Oracle Database Installation Guide for UNIX Systems.

• If you are installing Oracle Real Application Clusters, see the Oracle Real Application Clusters Installation and Configuration Guide

  This guide also describes how to install Oracle Cluster Ready Services, which is a prerequisite for RAC installations.

Both of these guides are available on the product disc. To access them, use a Web browser to open the welcome.htm file, either in the top-level directory of the CD-ROM or in the db directory on the DVD-ROM, then select the Documentation tab.

2 Log In to the System as root

Before you install the Oracle software, you must complete several tasks as the root user. To log in as the root user, complete one of the following procedures:

• If you are installing the software from an X Window System workstation or X terminal:

  1. Start a local terminal session, for example, an X terminal (xterm).

  2. If you are not installing the software on the local system, enter the following command to enable remote hosts to display X applications on the local X server:

     $ xhost +
     
     

  3. If you want to install the software on a remote system, enter a command similar to the following to connect to that system:

     $ telnet remote_host
     
     

  4. If you are not logged in as the root user, enter the following command to switch user to root:

     $ su - root
     password:
     #
     
     

• If you are installing the software from a PC or other system with X server software installed:

  
  

  Note: If necessary, see your X server documentation for more information about completing this procedure. Depending on the X server software that you are using, you may need to complete the tasks in a different order.

  
  

  1. Start the X server software.

  2. Configure the security settings of the X server software to permit remote hosts to display X applications on the local system.

  3. Connect to the remote system where you want to install the software and start a terminal session on that system, for example, an X terminal (xterm).

  4. If you are not logged in as the root user on the remote system, enter the following command to switch user to root:

     $ su - root
     password:
     #
     
     

3 Check the Hardware Requirements

The system must meet the following minimum hardware requirements:

To ensure that the system meets these requirements, follow these steps:

1. To determine the physical RAM size, enter the following command:

   # /bin/vmstat -P | grep "Total Physical Memory"
   
   

   If the size of the physical RAM installed in the system is less than 512 MB, you must install more memory before continuing.

2. To determine the size of the configured swap space, enter the following command:

   # /sbin/swapon -s
   
   

   If necessary, see your operating system documentation for information about how to configure additional swap space.

3. To determine the amount of free disk space available in the /tmp directory, enter the following command:

   # df -k /tmp
   
   

   If there is less than 400 MB of disk space available in the /tmp directory, complete one of the following steps:

   • Delete unnecessary files from the /tmp directory to achieve the required disk space.

   • Set the TEMP and TMPDIR environment variables when setting the oracle user’s environment (described later).

   • Extend the file system that contains the /tmp directory. If necessary, contact your system administrator for information about extending file systems.

4. To determine the amount of free disk space available on the system, enter the following command:

   # df -k
   
   

   This command displays the disk space usage on all mounted file systems. To complete the installation, the system must satisfy either of the following conditions:

   • 5.2 GB (5452596 KB) of free disk space is available on two file systems: one with at least 4.0 GB (4194304 KB) free for the Oracle software and another with at least 1.2 GB free for the preconfigured database

   • 5.2 GB of free disk space is available for the Oracle software and database on a single file system

     
     

     Note: While installing the Oracle database on a disk drive separate from the software does provide a performance improvement, for best performance, the Oracle database files should be distributed across three or more disks. The Oracle Database Installation Guide for UNIX Systems describes this more complex and time-consuming type of installation. However, this type of installation is recommended only for experienced users.

     
     

4 Check the Software Requirements

The system must meet the following minimum software requirements:

• The operating system version must be HP Tru64 UNIX V5.1B

• The following Operating system subsets must be installed:

  OSFCMPLRS
  OSFLIBA
  OSFPGMR
  OSFSER
  OSFX11
  
  

• Software Development Kit (SDK) v 1.4.2.01 for the Tru64 UNIX Operating System for the Java Platform (JDK 1.4.2) must be installed

• The following patch kits must be installed:

  • Tru64 UNIX V5.1B Patch Kit 2 or higher:

    T64V51BB22AS0002-20030415
    
    

  • Tru64 UNIX 5.1B PK2 BL22 Fixes for AdvFS Panic in _OtsMove; and Possible Memory Corruption:

    T64KIT0020879-V51BB22-E-20031125
    
    

To ensure that the system meets these requirements, follow these steps:

1. To determine which version of Tru64 UNIX is installed, enter the following command:

   # /usr/sbin/sizer -v
   Compaq Tru64 UNIX V5.1B (Rev. 2650); Mon Nov  3 10:13:28 PST 200
   
   

   In this example, the version shown is V5.1B. If necessary, see your operating system documentation for information about upgrading the operating system.

2. To determine whether the required software subsets are installed, enter one of the following commands:

   • To view the list of all software subsets installed on the system, enter the following command:

     # /usr/sbin/setld -i | more
     
     

   • To determine whether a particular software subset is installed, enter a command similar to the following:

     # /usr/sbin/setld -i | grep subsetname
     
     

3. To determine whether Java SDK 1.4.2 is installed, enter the following command:

   # /usr/sbin/setld -i JAVA142 | more
   
   

   If Java SDK 1.4.2 is installed, this command displays the paths to all of the installed files. Note the path of the Java home directory. You must specify this value during the installation. The default path is:

   /usr/opt/java142
   
   

   If this command returns the message Unknown subset, Java SDK 1.4.2 is not installed. Download Java SDK 1.4.2.01 or higher from the following Web site and install it:

   http://www.compaq.com/java/download/index.html
   
   

4. To determine whether the required patch kits are installed, enter the following command:

   # /usr/sbin/dupatch -track -type kit
   
   

   If this command does not display the identifiers for the required patch kits (or the identifier for a higher patch kit level), download the latest patch kit from the following Web site and install it (registration is required to access this Web site):

   http://itrc.hp.com/service/patch/mainPage.do
   
   

5 Create Required UNIX Groups and User

The following local UNIX groups and user must exist on the system:

• The oinstall group (the Oracle Inventory group)

• The dba group (the OSDBA group)

• The oracle user (the Oracle software owner)

The oinstall and dba groups and the oracle user may already exist on your system. To determine whether they exist already, and if necessary, to create them, follow these steps:

1. To determine whether the oinstall and dba groups exist, enter the following commands:

   # grep oinstall /etc/group
   # grep dba /etc/group
   
   

   If the output from these commands shows the specified group name, that group already exists.

2. If necessary, enter the following commands to create the oinstall and dba groups:

   # /usr/sbin/groupadd oinstall
   # /usr/sbin/groupadd dba
   
   

3. To determine whether the oracle user exists and belongs to the correct groups, enter the following command:

   # id oracle
   
   

   If the oracle user exists, this command displays information about the groups to which the user belongs. The output should be similar to the following, indicating that oinstall is the primary group and dba is a secondary group:

   uid=502(oracle) gid=502(oinstall) groups=502(oinstall),503(dba)
   
   

4. If necessary, complete one of the following actions:

   • If the oracle user exists, but its primary group is not oinstall or it is not a member of the dba group, enter the following command:

     # /usr/sbin/usermod -g oinstall -G dba oracle
     
     

   • If the oracle user does not exist, enter the following command to create it:

     # /usr/sbin/useradd -g oinstall -G dba oracle
     
     

     This command creates the oracle user and specifies:

     • oinstall as the primary group

     • dba as the secondary group

5. Enter the following command to set the password of the oracle user:

   # passwd oracle
   

6 Create Required Directories

Create directories with names similar to the following and specify the correct owner, group, and permissions for them:

• /u01/app/oracle (the Oracle base directory)

• /u02/oradata (an optional Oracle datafile directory)

The Oracle base directory must have 4.0 GB (4194304 KB) of free disk space, or 5.2 GB (5452596 KB) of free disk space if you choose not to create a separate Oracle datafile directory. The Oracle datafile directory must have 1.2 GB of free disk space.

To determine where to create these directories, follow these steps:

1. Enter the following command to display information about all mounted file systems:

   # df -k
   
   

   This command displays information about all of the file systems mounted on the system, including:

   • The physical device name

   • The total amount, used amount, and available amount of disk space, in kilobytes

   • The mount point directory for that file system

2. From the display, identify either one or two file systems that meet the following requirements:

   • Two file systems:

     Identify one file system with 4.0 GB of free disk space, for the Oracle base directory, and another file system with 1.2 GB of free disk space for the Oracle datafile directory.

   • One file system:

     Identify one file system with 5.2 GB of free disk space, for both the Oracle base directory and the Oracle datafile directory.

3. Note the name of the mount point directory for each file system that you identified.

   In the following examples, /u01 is the mount point directory used for the software and /u02 is the mount point directory used for the Oracle datafile directory. You must specify the appropriate mount point directories for the file systems on your system.

To create the required directories and specify the correct owner, group, and permissions for them, follow these steps:

1. Enter the following command to create subdirectories in the mount point directory that you identified for the Oracle base directory:

   # mkdir -p /u01/app/oracle
   
   

2. If you intend to use a second file system for the Oracle database files, create an oradata subdirectory in the mount point directory that you identified for the Oracle datafile directory (shown as /u02 in the examples):

   # mkdir /u02/oradata
   
   

3. Change the owner and group of the directories that you created to the oracle user and the oinstall group:

   # chown -R oracle:oinstall /u01/app/oracle /u02/oradata
   
   

4. Change the permissions on the directories that you created to 775:

   # chmod -R 775 /u01/app/oracle /u02/oradata
   
   

7 Configure Kernel Subsystem Attributes

Verify that the kernel subsystem attributes shown in the following table are set to values greater than or equal to the recommended value shown. The procedure following the table describes how to verify and set the values.

To view the current value specified for these kernel subsystem attributes, and to change them if necessary, follow these steps:

1. To view the current values of the subsystem attributes, enter commands similar to the following:

   # /sbin/sysconfig -q subsystem
   
   

   For example, to view attribute values for the ipc subsystem, enter the following command:

   # /sbin/sysconfig -q ipc
   
   

2. If you must change any of the current values, follow these steps:

   1. Create a backup copy of the /etc/sysconfigtab file, for example:

      # cp /etc/sysconfigtab /etc/sysconfigtab.orig
      
      

   2. Using any text editor, create a file similar to the following, specifying the subsystems and attributes that you want to modify:

      ipc:
           shm_max = 4278190080
           shm_min = 1
           shm_mni = 256
           shm_seg = 128
      
      proc:
           per_proc_stack_size = 8388608
           max_per_proc_stack_size = 33554432
           per_proc_data_size = 201326592
           max_per_proc_data_size = 201326592
           max_per_proc_address_space = 4294967296
           per_proc_address_space = 4294967296
      
      

   3. Enter a command similar to the following to add the subsystem attributes to the /etc/sysconfigtab file:

      # /sbin/sysconfigdb -m -f filename
      
      

      In this example, filename is the name of the file you created in step b.

   4. Enter the following command to reboot the system:

      # /sbin/shutdown -r now
      
      

   5. When the system restarts, log in and switch user to root.

8 Mount the Product Disc

The Oracle Database 10g software is available on both CD-ROM and DVD-ROM. These discs are in ISO 9660 format with Rockridge extensions.

To mount the product disc, follow these steps:

1. If necessary, enter a command similar to following to unmount the currently mounted disc, then remove it from the drive:

   # /usr/sbin/umount /cdrom
   
   

   In this example, /cdrom is the mount point directory for the CD-ROM drive.

2. Insert the disc into the CD-ROM or DVD-ROM drive.

3. To mount the disc, enter a command similar to the following:

   # /usr/sbin/mount -t cdfs -o nodefperm,noversion /dev/disk/cdrom0c \
     /cdrom
   
   

   In this example, /cdrom is the CD-ROM mount point directory, which must exist, and /dev/disk/cdrom0c is the CD-ROM device name.

9 Log In as the oracle User and Configure the oracle User’s Environment

You run the Installer from the oracle account. However, before you start the Installer you must configure the environment of the oracle user. To configure the environment, you must:

• Set the default file mode creation mask (umask) to 022 in the shell startup file.

• Set the DISPLAY, ORACLE_BASE, and ORACLE_SID environment variables.

To set the oracle user’s environment, follow these steps:

1. Start another terminal session.

2. Enter the following command to ensure that X Window applications can display on this system:

   $ xhost +
   
   

3. Complete one of the following steps:

   • If the terminal session is not connected to the system where you want to install the software, log in to that system as the oracle user.

   • If the terminal session is connected to the system where you want to install the software, switch user to oracle:

     $ su - oracle
     
     

4. To determine the default shell for the oracle user, enter the following command:

   $ echo $SHELL
   
   

5. Open the oracle user’s shell startup file in any text editor:

   • Bourne shell (sh), Bash shell (bash), or Korn shell (ksh):

     $ vi .profile
     
     

   • C shell (csh or tcsh):

     % vi .login
     
     

6. Enter or edit the following line in the shell startup file, specifying a value of 022 for the default file creation mask:

   umask 022
   
   

7. Save the file and exit from the editor.

8. To run the shell startup script, enter the following command:

   • Bourne, Bash, or Korn shell:

     $ . ./.profile
     
     

   • C shell:

     % source ./.login
     
     

9. If you determined that the /tmp directory had insufficient free disk space when checking the hardware requirements, enter the following commands to set the TEMP and TMPDIR environment variables. Specify a directory on a file system with sufficient free disk space.

   • Bourne, Bash, or Korn shell:

     $ TEMP=/directory
     $ TMPDIR=/directory
     $ export TEMP TMPDIR
     
     

   • C shell:

     % setenv TEMP /directory
     % setenv TMPDIR /directory
     
     

10. If you are not installing the software on the local system, enter the following command to direct X applications to display on the local system:

    • Bourne, Bash, or Korn shell:

      $ DISPLAY=local_host:0.0 ; export DISPLAY
      
      

    • C shell:

      % setenv DISPLAY local_host:0.0
      
      

    In this example, local_host is the host name or IP address of the system you want to use to display the Installer (your workstation or PC).

11. Enter commands similar to the following to set the ORACLE_BASE and ORACLE_SID environment variables:

    • Bourne, Bash, or Korn shell:

      $ ORACLE_BASE=/u01/app/oracle
      $ ORACLE_SID=sales
      $ export ORACLE_BASE ORACLE_SID
      
      

    • C shell:

      % setenv ORACLE_BASE /u01/app/oracle
      % setenv ORACLE_SID sales
      
      

    In these examples, /u01/app/oracle is the Oracle base directory that you created earlier and sales is the name that you want to call the database (typically no more than five characters).

12. Enter the following commands to ensure that the ORACLE_HOME and TNS_ADMIN environment variables are not set:

    • Bourne, Bash, or Korn shell:

      $ unset ORACLE_HOME
      $ unset TNS_ADMIN
      
      

    • C shell:

      % unsetenv ORACLE_HOME
      % unsetenv TNS_ADMIN
      
      

13. To verify that the environment has been set correctly, enter the following commands:

    $ umask
    $ env | more
    
    

    Verify that the umask command displays a value of 022 and the environment variables that you set in this section have the correct values.

10 Install Oracle Database 10g

After configuring the oracle user’s environment, start the Installer and install the Oracle software, as follows:

$ /mount_point/db/runInstaller

1. To start the Installer, enter the following commands:

   $ cd /tmp
   $ /cdrom/runInstaller
   
   

   If the Installer does not appear, see the Oracle Database Installation Guide for UNIX Systems for information about how to troubleshoot X display problems.

14 Documentation Accessibility

Our goal is to make Oracle products, services, and supporting documentation accessible, with good usability, to the disabled community. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.
