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.

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:

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 1:

  • 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 requirement:

    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 1 GB 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 1:

  • The minimum disk space requirement for a client install in the /tmp directory is 130 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 (described later).

    • Extend the file system that contains the /tmp directory. If necessary, contact the system administrator for information about extending file systems.

  • Between 34 MB and 820 MB of disk space for the Oracle software, depending on the installation type

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

    # df -k
    
    Installation typr Requirement for Software Files (MB)
    Instant Client 150
    Administrator 935
    Runtime 660
    Custom (maximum) 850

4 Checking the Software Requirements

# rpm -q package_name

Note:

he numa package link for Linux x86 is /usr/lib/.

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 following are the compiler requirements for Pro*C/C++ , Oracle Call Interface, Oracle C++ Call Interface, and Oracle XML Developer's Kit (XDK) with Oracle Database 11g release 1:

Intel C++ Compiler 9.1 or later and the version of GNU C and C++ compilers listed under "Package Requirements" are supported with these products.

Note:

Intel Compiler v9.1 can be used only with gcc 3.4.5 or gcc 4.0 or gcc 4.1 standard template libraries to build Oracle C++ Call Interface (OCCI) applications.

Oracle XML Developer's Kit is supported with the same compilers as OCCI.

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 Driver Manager from the following URL:

http://www.unixodbc.org

Linux RPMs are available on the site. You do not require ODBC Driver Manager to install Oracle Database. To use ODBC, you must also install the following additional 32-bit ODBC RPMs, depending on your operating system:

  • On Asianux 2, Oracle Linux 4, and Red Hat Enterprise Linux 4:

    unixODBC-2.2.11 (32 bit) or later
    unixODBC-devel-2.2.11 (32 bit) or later
    
  • On Asianux 3, Oracle Linux 5, and Red Hat Enterprise Linux 5:

    unixODBC-2.2.11 (32 bit) or later
    unixODBC-devel-2.2.11 (32 bit) or later
    
  • On SUSE 10:

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

4.5.2 Oracle JDBC/OCI Drivers

You can use Sun JDK 1.5.0-06 with the JNDI extension JDK versions with the Oracle Java Database Connectivity and Oracle Call Interface drivers. However, these are not mandatory for the installation.

4.5.3 Browser Requirements

Web browsers must support Java Script and the HTML 4.0 and CSS 1.0 standards. The following Web browsers are supported for Oracle Enterprise Manager Database Control:

  • Firefox 1.0.4

  • Firefox 1.5

  • Firefox 2.0

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 already 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_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.

    See Also:

    PC-X Server or Operating System vendor documents for further assistance.
  8. If you determined that the /tmp directory has less than 400 MB of free disk space, then identify a file system with at least 400 MB 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:

      $ 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 these examples, /u01/app/oracle is the Oracle base directory that you created or identified earlier and sales is the name that you want to call 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:

    • Asianux, Oracle Linux, and Red Hat Enterprise Linux:

      $ sudo eject /mnt/dvd
      
    • SUSE:

      # 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:

    • Asianux, Oracle Linux, and Red Hat Enterprise Linux:

      # 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:

    • Asianux, Oracle Linux, and Red Hat Enterprise Linux:

      # 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.
