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:

    # 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, see your operating system documentation for information about how to configure additional swap space.

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

    # df -h /tmp
    
  4. To determine the amount of free disk space on the system, enter the following command:

    # df -h
    
  5. To determine the amount of free RAM and disk swap space on the system, enter the following command:

    # free
    
  6. To determine if the system architecture can run the software, enter the following command:

    # uname -m
    

    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.

3.2 General Server Minimum Requirements

Ensure the following general minimum requirements on your system:

  • Ensure that the system is started with runlevel 3 or runlevel 5.

  • 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

    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

7.6 Installation Requirements for Web Browsers

Web browsers are required only if you intend to use Oracle Enterprise Manager Database Express and Oracle Enterprise Manager Cloud Control. Web browsers must support JavaScript, and the HTML 4.0 and CSS 1.0 standards.

For a list of browsers that meet these requirements see the Enterprise Manager certification matrix on My Oracle Support:

https://support.oracle.com

See Also:

Oracle Enterprise Manager Cloud Control Basic Installation Guide for steps on how to access the Enterprise Manager certification matrix

8 Checking the Software Requirements

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

  1. To determine the distribution and version of Linux installed, enter one of the following commands:

    # lsb_release -id
    

    Note:

    Only the distributions and versions listed in Operating System Requirements for IBM: Linux on System z are supported. Do not install the software on other versions of Linux.
  2. To determine whether the required kernel errata is installed, enter the following command:

    # uname -r
    

    Review the required errata level for your distribution. If the errata level is previous to the required minimum errata update, then obtain and install the latest kernel update from your Linux distributor.

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

    # rpm -q package_name
    

    Alternatively, if you require specific system architecture information, then enter the following command:

    # rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n" | grep package_name
    

    You can also combine a query for multiple packages, and review the output for the correct versions. For example:

    # rpm -q binutils compat-libstdc++ gcc glibc libaio libgcc libstdc++ \
    make sysstat unixodbc
    

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

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, enter the following commands to create the oinstall and dba groups:

    # /usr/sbin/groupadd oinstall
    # /usr/sbin/groupadd dba
    
  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 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.

    Oracle does not support modifying an existing installation owner. See Oracle Database Installation Guide for more information.

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

    # passwd oracle
    

10 Configuring Kernel Parameters and Resource Limits

Verify that the kernel parameters shown in the following table are set to values greater than or equal to the minimum value shown. The procedure following the table describes how to verify and set the values.

Note:

    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

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

    1. 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 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 minimum value, then specify the larger value.
      fs.aio-max-nr = 1048576
      fs.file-max = 6815744
      kernel.shmall = 2097152
      kernel.shmmax = 536870912
      kernel.shmmni = 4096
      kernel.sem = 250 32000 100 128
      net.ipv4.ip_local_port_range = 9000 65500
      net.core.rmem_default = 262144
      net.core.rmem_max = 4194304
      net.core.wmem_default = 262144
      net.core.wmem_max = 1048586
      

      By specifying the values in the /etc/sysctl.conf file, they persist when you restart the system. However, on SUSE Linux Enterprise Server systems, enter the following command to ensure that the system reads the /etc/sysctl.conf file when it restarts:

      # /sbin/chkconfig boot.sysctl on
      
    2. Enter the following command to change the current values of the kernel parameters:

      # /sbin/sysctl -p
      

      Review the output from this command to verify that the values are correct. If the values are incorrect, edit the /etc/sysctl.conf file, then enter this command again.

    3. Enter the command /sbin/sysctl -a to confirm that the values are set correctly.

    4. On SUSE systems only, enter the following command to cause the system to read the /etc/sysctl.conf file when it restarts:

      # /sbin/chkconfig boot.sysctl on
      
    5. On SUSE systems only, you must enter the GID of the oinstall group as the value for the parameter /proc/sys/vm/hugetlb_shm_group. Doing this grants members of oinstall a group permission to create shared memory segments.

      For example, where the oinstall group GID is 501:

      # echo 501 > /proc/sys/vm/hugetlb_shm_group
      

      After running this command, use vi to add the following text to /etc/sysctl.conf, and enable the boot.sysctl script to run on system restart:

      vm.hugetlb_shm_group=501
      

      Note:

      Only one group can be defined as the vm.hugetlb_shm_group.
    6. After updating the values of kernel parameters in the /etc/sysctl.conf file, either restart the computer, or run the command sysctl -p to make the changes in the /etc/sysctl.conf file available in the active kernel memory.

Check Resource Limits for the Oracle Software Installation Users

For each installation software owner, check the resource limits for installation, using the following recommended ranges:

Table 7 Installation Owner Resource Limit Recommended Ranges

Resource Shell Limit Resource Soft Limit (KB) Hard Limit (KB)

Open file descriptors

nofile

at least 1024

at least 65536

Number of processes available to a single user

nproc

at least 2047

at least 16384

Size of the stack segment of the process

stack

at least 10240

at least 10240, and at most 32768

Maximum Locked Memory Limit

memlock

at least 90 percent of the current RAM when HugePages memory is enabled and at least 3145728 KB (3 GB) when HugePages memory is disabled

at least 90 percent of the current RAM when HugePages memory is enabled and at least 3145728 KB (3 GB) when HugePages memory is disabled


To check resource limits:

  1. Log in as an installation owner.

  2. Check the soft and hard limits for the file descriptor setting. Ensure that the result is in the recommended range. For example:

    $ ulimit -Sn
    4096
    $ ulimit -Hn
    65536
    
  3. Check the soft and hard limits for the number of processes available to a user. Ensure that the result is in the recommended range. For example:

    $ ulimit -Su
    2047
    $ ulimit -Hu
    16384
    
    
  4. Check the soft limit for the stack setting. Ensure that the result is in the recommended range. For example:

    $ ulimit -Ss
    10240
    $ ulimit -Hs
    32768
    
  5. Repeat this procedure for each Oracle software installation owner.

If necessary, update the resource limits in the /etc/security/limits.conf configuration file for the installation owner. However, note that the configuration file is distribution specific. Contact your system administrator for distribution specific configuration file information.

Note:

If the grid or oracle users are logged in, then changes in the limits.conf file do not take effect until you log these users out and log them back in. You must do this before you use these accounts for installation.

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 Mounting the Product Disc

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

    • Oracle Linux and 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:

    • Oracle Linux and 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:

    • Oracle Linux and 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.

14 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 Linux for information about how to troubleshoot X Window display problems.
