Oracle® Database

1 Review Information About this Guide

This guide describes how to complete a default installation of Oracle Client in a new Oracle home directory. It describes how to perform one of the following installation types:

• Administrator: Enables applications to connect to an Oracle database on the local system or on a remote system. It also provides tools that allow you to administer an Oracle database.

• Runtime: Enables applications to connect to an Oracle database on the local system or on a remote system.

• Instant Client: Enables you to install only the shared libraries required by Oracle Call Interface applications that use the Instant Client feature. This installation type requires much less disk space than the other Oracle Client installation types.

For more detailed information about installing Oracle Client, see the Oracle Database Client Installation Guide for UNIX Systems.

This guide is available on the product disc. To access it, use a Web browser to open the welcome.htm file, either in the top-level directory of the CD-ROM or in the client 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 256 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, identify a file system with sufficient disk space.

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 Group and User

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

• The oinstall group (the Oracle Inventory group)

• The oracle user (the Oracle software owner)

The oinstall group 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 group exists, enter the following command:

   # grep oinstall /etc/group
   
   

   If the output from this command shows the specified group name, that group already exists.

2. If necessary, enter the following command to create the oinstall group:

   # /usr/sbin/groupadd oinstall
   
   

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:

   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, enter a command similar to the following, where the -g option specifies oinstall as the primary group and the -G option specifies any existing groups to which the oracle user belongs:

     # /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 an optional secondary group

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

   # passwd oracle
   

6 Create an Oracle Base Directory

Create an Oracle base directory with a name similar to the following and specify the correct owner, group, and permissions for it:

/u01/app/oracle

The Oracle base directory must have between 150 MB (153600 KB) and 1.9 GB (1992295 KB) of free space depending on the installation type you choose:

To determine where to create this directory, 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 a file system that has sufficient disk space.

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

   In the following examples, /u01 is the mount point directory used for the software. You must specify the appropriate mount point directory for the file system on your system.

To create the required directory and specify the correct owner, group, and permissions for it, 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. Change the owner and group of the directory that you created to the oracle user and the oinstall group:

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

3. Change the permissions on the directory that you created to 775:

   # chmod -R 775 /u01/app/oracle
   
   

7 Mount the Product Disc

The Oracle Client 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.

8 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 and ORACLE_BASE 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 environment variable:

    • Bourne, Bash, or Korn shell:

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

    • C shell:

      % setenv ORACLE_BASE /u01/app/oracle
      
      

    In these examples, /u01/app/oracle is the Oracle base directory that you created earlier.

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.

9 Install Oracle Client

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

$ /mount_point/client/runInstaller

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

   $ cd /tmp
   $ /cdrom/runInstaller
