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:

• Following are the steps for 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, then enter the following command to enable the remote host to display X applications on the local X server:

     $ xhost fully_qualified_remote_host_name
     

     For example:

     $ xhost somehost.us.example.com
     

  3. If you are not installing the software on the local system, then use the ssh, rlogin, or telnet command to connect to the system where you want to install the software:

     $ telnet fully_qualified_remote_host_name
     

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

     $ su - root
     password:
     #
     

• Following are the steps for installing the software from a PC or other system with X server software:

  Note:

  If necessary, refer to your X server documentation, or contact your X server vendor or system administrator for more information about completing this procedure. Depending on the X server software that you are using, you may have 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, then enter the following command to switch user to root:

     $ su - root
     password:
     #

5 Creating Required Operating System Groups and Users

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

• The Oracle Inventory group (oinstall)

• The OSDBA group (dba)

• The Oracle software owner (oracle)

To determine whether these groups and users 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 exists.

   Note:

   In Oracle documentation, Oracle Inventory group is called oinstall. However, it is not mandatory to use the same name, you can enter a different name for the group.

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

   inventory_loc=/u01/app/oraInventory
   inst_group=oinstall
   

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

2. To determine whether the dba group exists, enter the following command:

   # grep dba /etc/group
   

   If the output from this commands shows the dba group name, then the group exists.

3. If necessary, use the following procedure to create the oinstall and dba groups:

   1. Enter the following command:

      # smit security
      

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

   3. Press F10 to exit.

4. 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 (for example) is the primary group and dba is a secondary group:

   uid=440(oracle) gid=200(oinstall) groups=201(dba),202(oper)
   

5. If the oracle user does not exist or to create the oracle user, then use the following procedure:

   1. Enter the following command:

      # smit security
      

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

      In the Primary GROUP field, specify the Oracle Inventory group, for example oinstall.

      In the Group SET field, specify the OSDBA group and if required, the OSOPER group. For example dba.

   3. Press F10 to exit.

6. If the oracle user exists, but its primary group is not oinstall or it is not a member of the dba group, then use the following procedure to modify the oracle user:

   1. Enter the following command:

      # smit security
      

   2. Choose the appropriate menu items to modify the oracle user, specifying the following information:

      In the Primary GROUP field, specify the Oracle Inventory group, for example oinstall.

      In the Group SET field, specify the OSDBA group and if required, the OSOPER group. For example dba.

   3. Press F10 to exit.

7. Set the password for the oracle user:

   # passwd oracle
   

6 Configure Shell Limits and System Configuration Parameters

This section contains the following topics:

• Configure Shell Limits

• Configure System Configuration Parameters

• Checking Asynchronous Input Output Processes

Oracle recommends that you set shell limits and system configuration parameters as described in this section.

# ioo –o aio_maxreqs
aio_maxreqs = 65536

# lsattr -El aio0 -a maxreqs
maxreqs 65536 Maximum number of REQUESTS True

# ps -ek|grep -v grep|grep –v posix_aioserver|grep -c aioserver

7 Creating Required Directories

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

• The Oracle base directory

• An optional Oracle data file directory

The Oracle base directory must have 3 GB of free disk space, or 4 GB of free disk space if you choose not to create a separate Oracle data file directory.

To create the Oracle base directory:

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

   # df -k
   

   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/
   

8 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:

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

• Set the DISPLAY environment variable.

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 somehost.us.example.com
   

3. If you are not logged in to the system where you want to install the software, then log in to that system as the oracle user.

4. If you are not logged in as the oracle user, then switch user to oracle:

   $ su - oracle
   

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

   $ echo $SHELL
   

6. To run the shell startup script, enter the following commands:

   • Bash shell:

     $ . ./.bash_profile
     

   • Bourne or Korn shell:

     $ . ./.profile
     

   • C shell:

     % source ./.login
     

7. If you are not installing the software on the local computer, then run the following command on the remote system 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 system 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
   

   In this 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.

8. If you determined that the /tmp directory has less than 1 GB of free disk space, then identify a file system with at least 1 GB of free space and set the TMP and TMPDIR environment variables to specify a temporary directory on this file system:

   1. To determine the free disk space on each mounted file system use the following command:

      # df -k /tmp
      

   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:

      su - root
      $ mkdir /mount_point/tmp
      $ 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
        

9. 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 this example, /u01/app/oracle is the Oracle base directory that you created or identified earlier and sales is the name of the database (typically no more than five characters).

10. 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
      

    Note:

    If the ORACLE_HOME environment variable is set, then Oracle Universal Installer uses the value that it specifies as the default path for the Oracle home directory. However, if you set the ORACLE_BASE environment variable, then Oracle recommends that you unset the ORACLE_HOME environment variable and choose the default path suggested by Oracle Universal Installer.

9 Running the rootpre.sh Script

Run the rootpre.sh script:

1. Switch user to root:

   $ su -
   password:
   #
   

2. Complete one of the following steps, depending on the location of the installation files:

   • If the installation files are on DVD, enter a command similar to the following, where directory_path is the disc mount point directory or the path of the db directory on the DVD:

     # /directory_path/rootpre/rootpre.sh 
     

   • If the installation files are on the hard disk, change the directory to the path where rootpre.sh exists and enter the following command:

     # ./rootpre.sh
     

3. Exit from the root account:

   # exit
   

10 Mounting the Product Disc

On most AIX based 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 -
   password:
   

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:

   /dvd
   

11 Installing Oracle Database

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

1. To start Oracle Universal Installer, enter the following command:

   $ /mount_point/db/runInstaller
