Where to Get Additional Installation Information

For more detailed information about installing Oracle Database Client, refer to Oracle Database Client Installation Guide for AIX 5L Based Systems (64-Bit).

This guide is available on the product disc. To access it, use a Web browser to open the welcome.htm file located in the top-level directory of the installation media, and then select the Documentation tab.

2 Logging 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:


You must install the software from an X Window System workstation, an X terminal, or a PC or other system with X server software installed

3 Checking the Hardware Requirements

The system must meet the following minimum hardware requirements:

3.1 Memory Requirements

The following are the memory requirements for installing Oracle Client 11g Release 1:

  • At least 256 GB of physical RAM

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

    # /usr/sbin/lsattr -E -l sys0 -a realmem

    If the size of the RAM is less than the required size, then you must install more memory before continuing.

  • The following table describes the relationship between installed RAM and the configured swap space requirement:

    Available RAM Swap Space Required
    Between 257 MB and 512 MB Double the size of RAM
    Between 513 MB and 2048 MB 1.5 times the size of RAM
    Between 2049 MB and 8192 MB Equal to the size of RAM
    More than 8192 MB 0.75 times the size of RAM

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

# /usr/sbin/lsps -a

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


Oracle recommends that you take multiple values for the available RAM and swap space before finalizing a value. This is because the available RAM and swap space keep changing depending on the user interactions with the computer.

3.2 System Architecture

To determine whether the system architecture can run the software, enter the following command:

# /usr/bin/getconf HARDWARE_BITMODE


This command displays the processor type. Verify that the processor architecture matches the Oracle software release that you want to install. If you do not see the expected output, then you cannot install the software on this system.

To determine if the system is started in 64-bit mode, enter the following command:

# bootinfo -K

The result of this command must be 64, indicating that the 64-bit kernel is enabled.

3.3 Disk Space Requirements

The following are the disk space requirements for installing Oracle Client 11g Release 1:

  • The minimum disk space requirement for a client install in the /tmp directory is 190 MB

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

    # df -m /tmp

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

    • Delete unnecessary files from the /tmp directory to meet the disk space requirement.

    • Set the TMP 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 the system administrator for information about extending file systems.

  • To determine the amount of free disk space on the system, enter the following command:

    • GPFS:

      # df -k
    • Raw Logical Volumes in Concurrent VG (HACMP); in the following example, the variable lv_name is the name of the raw logical volume whose space you want to verify:

      # lslv lv_name
    • Raw hard disks; in the following example, the variable rhdisk# is the raw hard disk number that you want to verify, and the variable size_mb is the size in megabytes of the partition that you want to verify:

      # lsattr -El rhdisk# -a size_mb
    Installation Type Requirement for Software Files (MB)
    Instant Client 340
    Administrator 3.5 (GB)
    Runtime 2.3 (GB)
    Custom (maximum) 3.7 (GB)

4 Checking the Software Requirements

5 Creating Required Operating System Groups and Users

The following local operating system groups and users are required if you are installing Oracle Client:

To determine whether these groups and users already exist, and if necessary, to create them, follow these steps:

  1. To determine whether the oinstall group exists, enter the following command:

    # more /etc/oraInst.loc

    If the output of this command shows the oinstall group name, then the group already exists.

    If the oraInst.loc file exists, then the output from this command is similar to the following:


    The inst_group parameter shows the name of the Oracle Inventory group, oinstall.

  2. If necessary, enter the following commands 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, then 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=440(oracle) gid=200(oinstall) groups=201(dba),202(oper)
  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, then 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 and dba as the secondary group.

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

    # passwd oracle

6 Creating Required Directories


If you do not want to create a separate Oracle data file directory, then you can install the data files in a subdirectory of the Oracle base directory. However, this is not recommended for production databases.

To create the Oracle base directory:

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

    # df -h

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

    • The physical device name

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

    • The mount point directory for that file system

  2. From the display, identify either one or two file systems that meet the disk space requirements mentioned earlier in this section.

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

  4. Enter commands similar to the following to create the recommended subdirectories in the mount point directory that you identified and set the appropriate owner, group, and permissions on them:

    # mkdir -p /mount_point/app/
    # chown -R oracle:oinstall /mount_point/app/
    # chmod -R 775 /mount_point/app/

    For example:

    # mkdir -p /u01/app/
    # chown -R oracle:oinstall /u01/app/
    # chmod -R 775 /u01/app/

7 Configuring the oracle User's Environment

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

To set the oracle user's environment:

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

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

    $ xhost fully_qualified_remote_host_name

    For example:

    $ 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, then 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, then 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:

    • Bash shell (bash) on SUSE:

      $ vi .profile
    • Bourne shell (sh), Bash shell on Red Hat (bash), or Korn shell (ksh):

      $ vi .bash_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 mode creation mask:

    umask 022
  7. If the ORACLE_SID, ORACLE_HOME, or ORACLE_BASE environment variable is set in the file, then remove the corresponding lines from the file.

  8. Save the file, and exit from the editor.

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

    • Bash shell on Red Hat:

      $ . ./.bash_profile
    • Bourne shell, Bash shell on SUSE, or Korn shell:

      $ . ./.profile
    • C shell:

      % source ./.login
  10. If you are not installing the software on the local computer, then run the following command on the remote machine to set the DISPLAY variable:

    • Bourne, Bash or Korn shell:

      $ export DISPLAY=local_host:0.0      
    • C shell:

      % setenv DISPLAY local_host:0.0

    In this example, local_host is the host name or IP address of the local computer that you want to use to display Oracle Universal Installer.

    Run the following command on the remote machine to check if the shell and the DISPLAY environmental variable are set correctly:

    echo $SHELL
    echo $DISPLAY

    Now to enable X applications, run the following commands on the local computer:

    $ xhost + fully_qualified_remote_host_name

    To verify that X applications display is set properly, run a X11 based program that comes with the operating system such as xclock:

    $ xclock_path

    In this example, xclock_path is the directory path. For example, you can find xclock at /usr/X11R6/bin/xclocks. If the DISPLAY variable is set properly, then you can see xclock on your computer screen.


    PC-X Server or Operating System vendor documents for further assistance.
  11. If you determined that the /tmp directory had insufficient free disk space when checking the hardware requirements, then identify a file system with the required amount of free space and set the TMP and TMPDIR environment variables as follows:

    1. Use the df -k command to identify a suitable file system with sufficient free space.

    2. If necessary, enter commands similar to the following to create a temporary directory on the file system that you identified, and set the appropriate permissions on the directory:

      # sudo mkdir /mount_point/tmp
      # sudo chmod a+wr /mount_point/tmp
      # exit
    3. Enter commands similar to the following to set the TMP and TMPDIR environment variables:

      Bourne, Bash, or Korn shell:

      $ TMP=/mount_point/tmp
      $ TMPDIR=/mount_point/tmp
      $ export TMP TMPDIR

      C shell:

      % setenv TMP /mount_point/tmp
      % setenv TMPDIR /mount_point/tmp
  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 22, 022, or 0022 and the environment variables that you set in this section have the correct values.

8 Mounting the Product Disc

On most AIX systems, the product disc mounts automatically when you insert it into the drive. If the disc does not mount automatically, then follow these steps to mount it:

  1. Switch user to root:

    $ su -
  2. If necessary, enter a command similar to the following to eject the currently mounted disc, then remove it from the drive:

    # umount /dvd
  3. Insert the disc into the disc drive, then enter a command similar to the following to mount it:

    # /usr/sbin/mount -rv cdrfs /dev/cd0 /dvd

    In this example, /dev/cd0 is the device name of the disc drive and /dvd is the mount point directory.

  4. If Oracle Universal Installer displays the Disk Location dialog box, enter the disc mount point directory path, for example:


9 Installing Oracle Client

After configuring the oracle user's environment, start Oracle Universal Installer and install Oracle Client as follows:

10 What to Do Next?
