See Also:

Oracle Call Interface Programmer's Guide for more information about Instant Client

This guide does not describe how to install the Custom installation type.

Where to Get Additional Installation Information

For more detailed information about installing Oracle Database Client, refer to Oracle Database Client Installation Guide for Linux.

All 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 media. Platform-specific documentation is available in PDF and HTML formats in the Documentation section..

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:

Note:

Unless you intend to complete a silent-mode installation, 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 Database 11g Release 2 (11.2):

  • At least 256 MB of physical RAM.

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

    # grep MemTotal /proc/meminfo
    

    If the size of the physical 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 recommendation:

    Note:

    On Linux, the HugePages feature allocates non-swappable memory for large page tables using memory-mapped files. If you enable HugePages, then you should deduct the memory allocated to HugePages from the available RAM before calculating swap space.
    Available RAM Swap Space Required
    Between 0 MB and 256 MB 3 times the size of RAM
    Between 256 MB and 512 MB 2 times the size of RAM
    Between 512 MB and 2 GB 1.5 times the size of RAM
    Between 2 GB and 16 GB Equal to the size of RAM
    More than 16 GB 16 GB

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

    # grep "model name" /proc/cpuinfo
    

    Note:

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

# grep SwapTotal /proc/meminfo

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

To determine the available RAM and swap space, enter the following command:

# free

Note:

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:

# uname -m

Note:

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.

3.3 Disk Space Requirements

The following are the disk space requirements for installing Oracle Database 11g Release 2 (11.2):

  • The minimum disk space requirement for a client install in the /tmp directory is 400 MB.

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

    # df -k /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.

      See Also:

      "Configuring the oracle User's Environment for more information about setting TMP and TMPDIR
    • Extend the file system that contains the /tmp directory. If necessary, contact the system administrator for information about extending file systems.

  • Between 146 MB and 1.38 GB of disk space for the Oracle software, depending on the installation type:

    Installation Type Requirement for Software Files
    Instant Client 146 MB
    Administrator 1.38 GB
    Runtime 1.10 GB

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

    # df -k
    

4 Checking the Software Requirements

Depending on the products that you intend to install, verify that the following software are installed on the system.

4.1 Operating System Requirements

The following or later versions of the operating system are required for Oracle Database 11g Release 2 (11.2):

  • Red Hat Enterprise Linux 4 Update 8

  • Red Hat Enterprise Linux 5 Update 4

  • SUSE Linux Enterprise Server 10 SP3

  • SUSE Linux Enterprise Server 11 SP1

Starting with Oracle Database 11g Release 2 (11.2), the Security Enhanced Linux (SE Linux) feature is supported for Red Hat Enterprise Linux 4, and Red Hat Enterprise Linux 5.

Note:

Only the distributions and versions listed in the earlier list are supported. Do not install the software on other versions of Linux.

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

To determine the distribution and version of Linux installed, enter the following command:

# cat /proc/version

4.2 Kernel Requirements

The following are the Kernel requirements for Oracle Database 11g Release 2 (11.2)

  • For Red Hat Enterprise Linux 4

    2.6.9 or later

  • For Red Hat Enterprise Linux 5

    2.6.18 or later

  • For SUSE Linux Enterprise Server 10

    2.6.16.21 or later

  • For SUSE Linux Enterprise Server 11

    2.6.27.19 or later

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

# uname -r

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

2.6.9-34.0.1.0.11.ELsmp

In this example, the output shows the kernel version (2.6.9) and errata level (34.0.1.0.11) on the system.

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

4.3 Package Requirements

The following, or later versions, packages are required for Oracle Database 11g Release 2 (11.2):

Note:

  • Oracle recommends that you install your Linux operating system with the default software packages (RPMs), unless you specifically intend to perform a minimal installation, and follow the directions for performing such an installation to ensure that you have all required packages for Oracle software.

  • Oracle recommends that you do not customize RPMs during a default operating system installation. A default installation includes most required packages, and helps you to limit manual checks of package dependencies.

  • You must install the packages (or later versions) listed in the following table. Also, ensure that the list of RPMs and all the prerequisites for these RPMs are installed.

  • If you did not perform a default Linux installation, you intend to use LDAP, and you want to use the scripts odisrvreg, oidca, or schemasync, then install the Korn shell RPM for your Linux distribution.

See "Oracle ODBC Drivers" for information on ODBC packages.

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 the Linux distribution media or download the required package version from the Linux vendor's Web site.

4.4 Compiler Requirements

The version of GNU C and C++ compilers listed under the "Package Requirements" are supported with these products.

4.5 Additional Software Requirements

Depending on the components you want to use, you must ensure that the following software are installed:

4.5.1 Oracle ODBC Drivers

You should install ODBC Driver Manager for UNIX. You can download and install the most recent ODBC Driver Manager from the following URL:

http://www.unixodbc.org

To use ODBC, you must also install the following additional ODBC RPMs, depending on your operating sytem:

  • On Red Hat Enterprise Linux 4:

    • unixODBC-2.2.11 (32-bit) or later

    • unixODBC-devel-2.2.11 (64-bit) or later

    • unixODBC-2.2.11 (64-bit) or later

  • On Red Hat Enterprise Linux 5:

    • unixODBC-2.2.11 (32-bit) or later

    • unixODBC-devel-2.2.11 (64-bit) or later

    • unixODBC-2.2.11 (64-bit) or later

  • On SUSE Linux Enterprise Server 10:

    • unixODBC-32 bit-2.2.11 (32-bit) or later

    • unixODBC-2.2.11 (64-bit) or later

    • unixODBC-devel-2.2.11 (64-bit) or later

    • unixODBC-devel-2.2.12 or later

    • unixODBC-32bit-2.2.12 (32-bit) or later

4.5.2 Oracle JDBC/OCI Drivers

You can use JDK 6 (Java SE Development Kit 1.6.0_21) or JDK 5 (1.5.0_24) with the JNDI extension with the Oracle Java Database Connectivity and Oracle Call Interface drivers. However, these are not mandatory for the database installation. Note that IBM JDK 1.5 is installed with this release.

4.5.3 Linux-PAM Library

Install the latest Linux-PAM (Pluggable Authentication Modules for Linux) library to enable the system administrator to choose how applications authenticate users.

4.5.4 Separate 32-Bit Client Software for 64-Bit Platforms

Starting with Oracle Database 11g Release 2 (11.2), the 64-bit client software does not contain any 32-bit client binaries. If you require 32-bit client binaries on 64-bit platforms, then install the 32-bit binaries from the respective 32-bit client software.

However, when you install the 32-bit client binaries on 64-bit platforms, the installer checks for the existence of 32-bit software such as the packages.

5 Creating Required Operating System Groups and Users

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 /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:

    inventory_loc=/u01/app/oraInventory
    inst_group=oinstall
    

    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

Note:

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 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 one of 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 computer 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 computer 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.

    See Also:

    PC-X Server or operating system vendor documents for further assistance
  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 -h /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:

      $ 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
        
  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.

8 Mounting the Product Disc

On most Linux 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. Enter a command similar to the following to eject the currently mounted disc, then remove it from the drive:

    • Red Hat Enterprise Linux:

      $ sudo eject /mnt/dvd
      
    • SUSE Linux Enterprise Server:

      # eject /media/dvd
      

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

  2. Insert the DVD into the disc drive.

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

    • Red Hat Enterprise Linux:

      # ls /mnt/dvd
      
    • SUSE Linux Enterprise Server:

      # 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 Enterprise Linux:

      # mount -t iso9660 /dev/dvd /mnt/dvd
      
    • SUSE Linux Enterprise Server:

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

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