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:


Note:

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

3 Check the Hardware Requirements

The system must meet the following minimum hardware requirements:

Requirement Minimum Value
Physical memory (RAM) 512 MB (524288 KB)
Swap space Twice the size of RAM or 2 GB (2097152 KB), whichever is smaller
Disk space in /tmp 400 MB (409600 KB)
Disk space for software files 4.0 GB (4194304 KB)

This value includes 1 GB (1048576 KB) of disk space required to install the Oracle Database 10g Products from the Companion CD (optional, but recommended).

Disk space for database files 1.2 GB (1258290 KB)
System architecture 64-bit

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

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

    # /usr/sbin/lsattr -E -1 sysO -a realmem
    
    

    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:

    # /usr/sbin/lsps -a
    
    

    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.

  5. To determine whether the system architecture is 64-bit, enter the following command:

    # /usr/bin/getconf HARDWARE_BITMODE
    
    

    This command should return the following output. If you do not see the expected output, you cannot install the software on this system.

    64
    
    

4 Check the Software Requirements

The system must meet the following minimum software requirements:

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

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

    # oslevel -r
    5200-01
    
    

    If the operating system version is lower than AIX 5.2.0.0 Maintenance Level 1 (5200-01), upgrade your operating system to this level or higher. AIX maintenance packages are available from the following IBM Web site:

    https://techsupport.services.ibm.com/server/aix.fdc
    
    
  2. To determine whether the required filesets are installed and committed, enter the following command:

    # lslpp -l bos.adt.base bos.adt.lib bos.adt.libm bos.perf.perfstat \
    bos.perf.libperfstat bos.perf.proctools
    
    

    If a fileset is not installed and committed, then install if from the operating system CD-ROM. See your operating system or software documentation for information about installing filesets.

  3. To determine whether an APAR is installed, enter a command similar to the following:

    # /usr/sbin/instfix -i -k "IY43980 IY44810 IY45462 IY45707 IY46214 \  
      IY46605 IY48525 IY51801"
    
    

    If an APAR is not installed, download it from the following Web site and install it:

    https://techsupport.services.ibm.com/server/aix.fdc
    
    

5 Create Required UNIX Groups and User

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

To create this user and these groups, follow these steps:

  1. Enter the following command:

    # smit security
    
    
  2. Choose the appropriate menu items to create the oinstall and dba groups.

  3. Choose the appropriate menu items to create the oracle user, specifying the following information:

    • In the Primary GROUP field, specify oinstall.

    • In the Group SET field, specify dba.

  4. After you have added the user and groups, press F10 to exit.

  5. 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:

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.


Note:

If you do not want to create a separate Oracle datafile directory, you can install the datafiles in a subdirectory of the Oracle base directory (not recommended for production databases).

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:


Note:

In the following procedure, replace /u01 and /u02 with the appropriate mount point directories that you identified in Step 3 previously.

  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 Shell Limits and System Configuration Parameters

On AIX systems, you do not need to configure kernel parameters. However, Oracle recommends that you set shell limits and system configuration parameters as described in this section.


Configure Shell Limits

Verify that the shell limits shown in the following table are set to the values shown. The procedure following the table describes how to verify and set the values.

Shell Limit (As Shown in smit) Recommended Value
Soft FILE size -1 (Unlimited)
Soft CPU time -1 (Unlimited)

Note: This is the default value.

Soft DATA segment -1 (Unlimited)
Soft STACK size -1 (Unlimited)

To view the current value specified for these shell limits, and to change them if necessary, follow these steps:

  1. Enter the following command:

    # smit chuser
    
    
  2. In the User NAME field, enter the user name of the Oracle software owner, for example oracle.

  3. Scroll down the list and verify that the value shown for the soft limits listed in the previous table is -1.

    If necessary, edit the existing value.

  4. When you have finished making changes, press F10 to exit.


Configure System Configuration Parameters

Verify that the maximum number of processes allowed per user is set to 2048 or greater, as follows:

  1. Enter the following command:

    # smit chgsys
    
    
  2. Verify that the value shown for Maximum number of PROCESSES allowed per user is greater than or equal to 2048.

    If necessary, edit the existing value.

  3. When you have finished making changes, press F10 to exit.

8 Mount the Product Disc and Run the rootpre.sh Script

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:

    # 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 -rv cdrfs /dev/cd0 /cdrom
    
    
  4. To run the rootpre.sh script, enter one of the following commands:

    • CD-ROM installation:

      # /cdrom/rootpre.sh
      
      
    • DVD-ROM installation:

      # /cdrom/db/rootpre.sh
      
      

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:

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 (bsh), Bash shell (bash), or Korn shell (sh or 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
