1 Reviewing Information About This Guide

This guide describes how to install Oracle Database by using the default installation options.

Tasks Described in This Guide

The procedures in this guide describe how to:

  • Configure your system to support Oracle Database

  • Install Oracle Database on a local file system by using the Typical Installation option

  • Configure a general-purpose Oracle Database installation that uses the local file system for database file storage

Results of a Successful Installation

After you successfully install Oracle Database:

  • The database that you created and the default Oracle Net listener process run on the system.

  • Oracle Enterprise Manager Database Express runs on the system and can be accessed using a web browser.

Tasks Not Described in This Guide

This guide covers the Typical Installation scenario and does not describe how to complete the following tasks:

  • Using the Advanced Installation option to install the software

  • Installing the software on a system that has an existing Oracle software installation

  • Installing Oracle Clusterware and Oracle Real Application Clusters on a cluster

  • Setting UDP and TCP kernel parameters manually

  • Using alternative storage options such as Oracle Automatic Storage Management

  • Installing and configuring Oracle Grid Infrastructure

  • Checking shared memory file system mount

Where to Get Additional Installation Information

For more information about installing Oracle Database, including information about the tasks not described in this guide, refer to one of the following guides:

The product documentation for Oracle Database products is available in both HTML and PDF formats online on the Oracle Technology Network (OTN) website:

http://www.oracle.com/technetwork/indexes/documentation/index.html

2 Logging In to the System as root

During installation, you must perform tasks as root or as other users on remote terminals. Complete the following procedure for user accounts that you want to enable for remote display.

Note:

If you log in as another user (for example, grid), then repeat this procedure for that user as well.

To log in as the root user and enable remote display, complete one of the following procedures:

  • If you are installing the software from an X Window System workstation or X terminal, then:

    1. Start a new X terminal session (xterm).

    2. If you are installing the software on another system and using the system as an X11 display, then enter a command using the following syntax to enable remote hosts to display X applications on the local X server:

      $ xhost + RemoteHost
      

      where RemoteHost is the fully qualified remote host name. For example:

      $ xhost + somehost.example.com
      somehost.example.com being added to the access control list
      
    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:

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

      $ su - root
      password:
      #
      
  • To install the software from a PC or other system with X server software:

    Note:

    If necessary, see the 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 Window System software.

    2. Configure the security settings of the X Window System 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 as the oracle software installation owner (oracle) and start an X terminal session (xterm) on that system.

    4. Open another terminal on the remote system, and log in as the root user on the remote system, so you can run scripts as root when prompted.

3 Configuring Servers for Oracle Database

This section describes the following operating system tasks you must complete before you install Oracle Database:

3.1 Checking Server Hardware and Memory Configuration

Run the following commands to check your current system information:

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

    # /usr/sbin/lsattr -E -l sys0 -a realmem
    
  2. To determine the available RAM and swap space, enter the following command:

    # /usr/sbin/lsps -s
    

    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. 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.

    Note:

    Contact your operating system vendor for swap space allocation guidance for your server. The vendor guidelines supersede the swap space requirements listed in this guide
  4. To determine the amount of space available in the /tmp directory, enter the following command:

    # df -m /tmp
    

    If the free space available in the /tmp directory is less than what is required, 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 Oracle Software Owner Environment" for more information about setting TMP and TMPDIR
    • Extend the file system that contains the /tmp directory.

  5. To determine the amount of free disk space on the system, enter one of the following commands:

    # df -g
    # df -m
    
  6. To determine if the system architecture can run the Oracle software, enter the following command:

    # /usr/bin/getconf HARDWARE_BITMODE
    

    The expected output of this command is 64. If you do not see the expected output, then you cannot install the software on this system.

    To determine if the system is started in 64-bit mode, enter the following command:

    # /usr/sbin/bootinfo -K
    

    The result of this command must be 64, indicating that the 64-bit kernel is enabled.

    Verify that the processor architecture matches the Oracle software release to install. If you do not see the expected output, then you cannot install the software on this system.

    Note:

    For AIX Based Systems, Oracle Database supports 64-bit kernel and does not provide support for 32-bit kernel applications
  7. To determine the run level enter the following command:

    /usr/bin/who -r
    

3.2 General Server Minimum Requirements

Ensure the following general minimum requirements on your system:

  • Ensure that the system is started with runlevel 2.

  • Ensure display cards provide at least 1024 x 768 display resolution, so that Oracle Universal Installer displays correctly while performing a system console-based installation

3.3 Server Storage Minimum Requirements

Ensure that your system meets the following minimum storage requirements.

  • Ensure that your system meets the disk space requirements for software files as described in Table 1

    Table 1 Disk Space Requirements for for IBM AIX on POWER Systems (64-Bit)

    9.1 GB


    Additional disk space, either on a file system or on an Oracle ASM disk group is required for the fast recovery area.

  • 1 GB of space in the /tmp directory.

    If the free space available in the /tmp directory is less than what is required, 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 Oracle Software Owner Environment" for more information about setting TMP and TMPDIR
    • Extend the file system that contains the /tmp directory.

3.4 Server Memory Minimum Requirements

Ensure that your system meets the following memory requirements:

Minimum: 1 GB of RAM

Recommended: 2 GB of RAM or more

Table 2 describes the relationship between the installed RAM and the configured swap space recommendation:

Table 2 Swap Space Requirement for IBM AIX on POWER Systems (64-Bit)

16 GB


4 Reviewing Operating System Security Common Practices

Secure operating systems are an important basis for general system security. Ensure that your operating system deployment is in compliance with common security practices as described in your operating system vendor security guide.

5 About Operating System Requirements

Depending on the products that you intend to install, verify that you have the required operating system kernel and packages installed.

Requirements listed in this document are current as of the date listed on the title page. To obtain the most current information about kernel requirements, see the online version on the Oracle Technology Network at the following URL:

http://www.oracle.com/technetwork/indexes/documentation/index.html

Oracle Universal Installer performs checks your system to verify that it meets the listed operating system package requirements. To ensure that these checks complete successfully, verify the requirements before you start OUI.

Note:

Oracle does not support running different operating system versions on cluster members, unless an operating system is being upgraded. You cannot run different operating system version binaries on members of the same cluster, even if each operating system is supported.

8 Checking the Software Requirements

To ensure that the system meets these requirements, perform the following steps:

  1. To determine the distribution and version of AIX installed, enter the following command:

    # oslevel -s
    

    If the operating system version is lower than what is listed in Operating System Requirements for IBM AIX on POWER Systems (64-Bit), then upgrade your operating system accordingly to the currently supported or later version and level.

    AIX maintenance packages are available from the following website:

    http://www-933.ibm.com/support/fixcentral/

  2. To determine if the required filesets are installed and committed, enter a command similar to the following:

    # lslpp -l bos.adt.base bos.adt.lib bos.adt.libm bos.perf.perfstat \
    bos.perf.libperfstat bos.perf.proctools
    
  3. To determine the supported kernel mode, enter a command similar to the following:

    # getconf KERNEL_BITMODE
    

    Note:

    • The expected output of this command is 64. If you do not see the expected output, then you cannot install the software on this system.

    • Oracle Database supports 64-bit kernel and does not provide support for 32-bit kernel applications.

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

    # /usr/sbin/instfix -i -k "IV16716 IV20880 IV21128 IV28319"
    

    If an APAR is not installed, then download it from the following website and install it:

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

    http://www-947.ibm.com/support/entry/portal/Overview/Software/WebSphere/WebSphere_MQ

9 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 (typically, oinstall)

  • The OSDBA group (typically, dba)

  • The Oracle software owner (typically, oracle)

  • The OSOPER group (optional. Typically, oper)

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.

    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. 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 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. Enter the following command to set the password of the oracle user:

    # passwd oracle
    

10 Configure Shell Limits and System Configuration Parameters

This section contains the following topics:

Note:

The parameter and shell limit values shown in this section are recommended values only. For production database systems, Oracle recommends that you tune these values to optimize the performance of the system. See your operating system documentation for more information about tuning kernel parameters.

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

10.1 Configure Shell Limits

For AIX, it is the ulimit settings that determine process memory related resource limits. Verify that the shell limits shown in the following table are set to the values shown.

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)
Soft Real Memory size -1 (Unlimited)
Processes (per user) -1 (Unlimited)

Note: This limit is available only in AIX 6.1 or later. See Configure System Configuration Parameters for information on configuration of processes per user limits.


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

  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.

10.2 Configure System Configuration Parameters

Verify that the kernel parameters shown in the following table are set to values greater than or equal to the minimum value shown.

Parameter Recommended Value
maxuprocs 2048
ncargs 128

The following procedure describes how to verify and set the values manually.

  • To verify that the maximum number of processes allowed per user is set to 2048 or greater, use the following steps:

    Note:

    For production systems, this value should be at least 128 plus the sum of the PROCESSES and PARALLEL_MAX_SERVERS initialization parameters for each database running on the system.
    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.

  • To verify that long commands can be executed from shell, use the following steps:

    Note:

    Oracle recommends that you set the ncargs system attribute to a value greater than or equal to 128. The ncargs attribute determines the maximum number of values that can be passed as command line arguments.
    1. Enter the following command:

      # smit chgsys
      
    2. Verify that the value shown for ARG/ENV list size in 4K byte blocks is greater than or equal to 128.

      If necessary, edit the existing value.

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

10.3 Checking Asynchronous Input Output Processes

On AIX 6 and AIX 7, the Asynchronous Input Output (AIO) device drivers are enabled by default. For both AIX 6 and AIX 7, increase the number of aioserver processes from the default value. The recommended value for aio_maxreqs is 64k (65536). Confirm this value for both AIX 6 and AIX 7.

Confirm the aio_maxreqs value using the following procedure:

# ioo –o aio_maxreqs
aio_maxreqs = 65536

When performing an asynchronous I/O to a file system, each asynchronous I/O operation is tied to an asynchronous I/O server. Thus, the number of asynchronous I/O servers limits the number of concurrent asynchronous I/O operations in the system.

The initial number of servers that are started during a system restart is determined by the aio_minservers parameter. As concurrent asynchronous I/O operations occur, additional asynchronous I/O servers are started, up to a maximum of the value set in the aio_maxservers parameter.

In general, to set the number of asynchronous I/O servers, complete the following procedure:

  1. Adjust the initial value of aio_maxservers to 10 times the number of logical disks divided by the number of CPUs that are to be used concurrently but no more than 80.

  2. Monitor the performance effects on the system during periods of high I/O activity. If all AIO server processes are started, then increase the maxservers value. Also, continue to monitor the system performance during peak I/O activity to determine if there was a benefit from the additional AIO servers. Too many asynchronous I/O servers increase memory and processor overload of additional processes, but this disadvantage is small. See your operating system vendor documentation for information about tuning AIO parameters.

To monitor the number of AIO server processes that have started, enter the following:

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

11 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.

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 -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/
    

12 Configuring Oracle Software Owner 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.

Caution:

Use shell programs supported by your operating system vendor. If you use a shell program that is not supported by your operating system, then you can encounter errors during installation.

To set the oracle user's environment:

  1. Start a new X terminal session (xterm).

  2. Enter the following command to ensure that X Window applications can display on this system:

    $ xhost + RemoteHost
    

    where RemoteHost is the fully qualified remote host name. For example:

    $ xhost + somehost.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 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
      
    • C shell:

      % setenv DISPLAY local_host:0.0
      

    In this example, local_host is the host name or IP address of the system to use to display Oracle Universal Installer (your workstation or PC).

  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 
      
    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. If you have had an existing installation on your system, and you are using the same user account to install this installation, then unset the ORACLE_HOME, ORACLE_BASE, ORACLE_SID, TNS_ADMIN environment variables and any other environment variable set for the Oracle installation user that is connected with Oracle software homes.

    Enter the following commands to ensure that the ORACLE_HOME, ORACLE_BASE, ORACLE_SID and TNS_ADMIN environment variables are not set:

    • Bourne, Bash, or Korn shell:

      $ unset ORACLE_HOME
      $ unset ORACLE_BASE
      $ unset ORACLE_SID
      $ unset TNS_ADMIN
      
    • C shell:

      % unsetenv ORACLE_HOME
      % unsetenv ORACLE_BASE % unsetenv ORACLE_SID
      % unsetenv TNS_ADMIN
      

    Use the following command to check the PATH environment variable:

    $ echo $PATH
    

    Ensure that the $ORACLE_HOME/bin path is removed from your PATH environment variable.

    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. 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.
  10. 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.

13 Running the rootpre.sh Script

Note:

Do not run the rootpre.sh script if you have a later release of the Oracle Database software installed on this system.

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
    

14 Mounting the Product Disc

On most systems, the disk mounts automatically when you insert it into the installation media. If the disk does not mount automatically, then follow these steps to mount it:

  1. Switch user to root:

    $ sudo root
    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
    

15 Installing Oracle Database

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

  1. Log on as the Oracle software owner user (typically, oracle) to the computer on which to install Oracle components.

  2. If you are installing the software from installation media, then mount the disk if it is not mounted.

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

    $ /mount_point/db/runInstaller
    

    If Oracle Universal Installer does not start, then refer to Oracle Database Installation Guide for IBM AIX on POWER Systems (64-Bit) for information about how to troubleshoot X Window display problems.
