Both these guides are available on the product disc. To access them, 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 Oracle Database, 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 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:

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

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

    # grep MemTotal /proc/meminfo

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

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

    # grep SwapTotal /proc/meminfo

    If necessary, refer to 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, then complete one of the following steps:

    • Delete unnecessary files from the /tmp directory.

    • 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 required, 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

    The following table shows the approximate disk space requirements for software files for each installation type.

    Installation Type Requirement for Software Files (GB)
    Enterprise Edition 1.5
    Standard Edition 1.5
    Custom (maximum) 1.5

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

    # grep "model name" /proc/cpuinfo

    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.

4 Checking the Software Requirements

The system must meet the following minimum software requirements, depending on the distribution and version of your operating system:

Note:

Oracle Universal Installer performs checks on your system to verify that it meets the listed requirements. To ensure that these checks pass, verify the requirements before you start Oracle Universal Installer.

For the Oracle products that you want to install, the system must meet the following product-specific requirements:

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

  1. To determine which distribution and version of the operating system is installed, enter the following command:

    # cat /etc/issue

  2. To determine whether the required kernel is installed, enter the following command:

    # uname -r

    The following is sample output displayed by running this command on a Red Hat Enterprise Linux 4.0 system:

    2.6.9-22.EL

    In this example, the output shows the kernel version (2.6.9) and errata level (22.EL) on the system.

    If the kernel version does not meet the requirement specified earlier in this section, then contact your operating system vendor for information about obtaining and installing kernel updates.

  3. To determine whether the required packages are installed, enter commands similar to the following:

    # rpm -q package_name

    If a package is not installed, then install it from your Linux distribution media or download the required package version from your Linux vendor's Web site.

  4. If you require a CSD for WebSphere MQ, then refer to the following Web site for download and installation information: 

    http://www-306.ibm.com/software/integration/wmq/support

5 Creating Required Operating System Groups and User

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

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 /var/opt/oracle/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:

    inventory_loc=/u01/app/oracle/oraInventory
inst_group=oinstall

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

    If the oraInst.loc file does not exist, then create the Oracle Inventory group by entering the following command:

    # /usr/sbin/groupadd oinstall

  2. If the OSDBA group does not exist or if you require a new OSDBA group, then create it as follows:

    # /usr/sbin/groupadd dba

    In this command, use the group name dba unless a group with that name already exists.

  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=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. To determine whether the nobody user exists, enter the following command:

    # id nobody

    If this command displays information about the nobody user, then you do not have to create the user.

    If the nobody user does not exist, then enter the following command to create it:

    # /usr/sbin/useradd nobody

    Specify the appropriate options to create an unprivileged nobody user, then press F10 to exit.

6 Configuring Kernel Parameters

Verify that the kernel parameters 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.

Parameter Value File

wmem_default 262144 /proc/sys/net/core/wmem_default
wmem_max 262144 /proc/sys/net/core/wmem_max

Note:

If the current value of any parameter is higher than the value listed in this table, then do not change the value of that parameter.

To view the current value specified for these kernel parameters, and to change them if necessary:

  1. Enter commands similar to the following to view the current values of the kernel parameters:

    Note:

    Make a note of the current values and identify any values that you must change.
    Parameter Command
    semmsl, semmns, semopm, and semmni # /sbin/sysctl -a | grep sem

    This command displays the value of the semaphore parameters in the order listed.
    shmall, shmmax, and shmmni # /sbin/sysctl -a | grep shm

    This command displays the details of the shared memory
    file-max # /sbin/sysctl -a | grep file-max

    This command displays the maximum number of file handles
    ip_local_port_range # /sbin/sysctl -a | grep ip_local_port_range

    This command displays a range of port numbers
    rmem_default # /sbin/sysctl -a | grep rmem_default
    rmem_max # /sbin/sysctl -a | grep rmem_max
    wmem_default # /sbin/sysctl -a | grep wmem_default
    wmem_max # /sbin/sysctl -a | grep wmem_max

  2. If the value of any kernel parameter is different from the recommended value, then complete the following steps:

    Using any text editor, create or edit the /etc/sysctl.conf file and add or edit lines similar to the following:

    Note:

    Include lines only for the kernel parameter values that you want to change. For the semaphore parameters (kernel.sem), you must specify all four values. However, if any of the current values are larger than the recommended value, specify the larger value.
    kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144

    By specifying the values in the /etc/sysctl.conf file, they persist when you restart the system.

    On SUSE systems only, enter the following command to ensure that the system reads the /etc/sysctl.conf file when it restarts:

    # /sbin/chkconfig boot.sysctl on

Set Shell Limits for the oracle User

To improve the performance of the software, you must increase the following shell limits for the oracle user:

Shell Limit Item in limits.conf Hard Limit
Maximum number of open file descriptors nofile 65536
Maximum number of processes available to a single user nproc 16384

To increase the shell limits:

  1. Add the following lines in the /etc/security/limits.conf file:

    oracle           soft    nproc   2047
oracle           hard    nproc   16384
oracle           soft    nofile  1024
oracle           hard    nofile  65536

  2. Add the following line to the /etc/pam.d/login file, if it does not already exist:

    session    required     /lib/security/pam_limits.so
session    required     pamlimit.so

  3. Depending on the oracle user's default shell, make the following changes to the default shell startup file:

    • For the Bourne, Bash, or Korn shell, add the following lines in the /etc/profile file (or the /etc/profile.local file on SUSE systems):

      if [ $USER = "oracle" ]; then
        if [ $SHELL = "/bin/ksh" ]; then
              ulimit -p 16384
              ulimit -n 65536
        else
              ulimit -u 16384 -n 65536
        fi
fi

    • For the C shell, add the following lines in the /etc/csh.login file (or the /etc/csh.login.local file on SUSE systems):

      if ( $USER == "oracle" ) then
        limit maxproc 16384
        limit descriptors 65536
endif

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 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 determine where to create these directories, perform the following:

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, in kilobytes

    • The mount point directory for that file system

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

  3. 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/oracle_sw_owner
# chown -R oracle:oinstall /mount_point/app/oracle_sw_owner
# chmod -R 775 /mount_point/app/oracle_sw_owner

    For example, if the mount point you identify is /u01 and oracle is the user name of the Oracle software owner, then the recommended Oracle base directory path is as follows:

    /u01/app/oracle

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:

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

  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:

    • Bourne shell (sh), Bash shell (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:

      $ . ./.bash_profile

    • Bourne shell, or Korn shell:

      $ . ./.profile

    • C shell:

      % source ./.login

  10. If you are not installing the software on the local system, then enter a command similar to the following 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 that you want to use to display Oracle Universal Installer (your workstation or PC).

  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

    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 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

  13. 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

  14. 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.

9 Mounting the Product Disc

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

    • Red Hat:

      $ sudo eject /mnt/dvd

    • SUSE:

      $ sudo eject /media/dvd

    In these examples, /mnt/dvd and /media/dvd are the mount point directories for the disc drive.

  2. Insert the appropriate disc into the disc drive.

  3. To verify that the disc mounted automatically, enter a command similar to the following:

    • Red Hat:

      $ ls /mnt/dvd

    • SUSE:

      $ ls /media/dvd

  4. If this command fails to display the contents of the disc, then enter a command similar to the following:

    • Red Hat:

      # mount -t iso9660 /dev/dvd /mnt/dvd

    • SUSE:

      # mount -t iso9660 /dev/dvd /media/dvd

    In these examples, /mnt/dvd and /media/dvd are the mount point directories for the disc drive.

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

    /mnt/dvd

10 Installing Oracle Database

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

Note:

If you are installing the software from a DVD, then use a command similar to the following: 
$ /mount_point/db/runInstaller

  1. To start Oracle Universal Installer, complete one of the following steps depending on the location of the installation files:

    • If the installation files are on disc, enter commands similar to the following, where directory_path is the path of the db directory on the DVD:

      $ cd /tmp
$ /directory_path/runInstaller

    • If the installation files are on the hard disk, change directory to the db directory and enter the following command:

      $ ./runInstaller

    If Oracle Universal Installer does not start, then refer to Oracle Database Installation Guide for IBM zSeries Based Linux for information about how to troubleshoot X Window display problems.
