4.5 Postinstallation Steps

This section consists of the following topics:

4.5.1 Resetting Root Password

The default root password for the Oracle Exalytics Release 2.2 Base Image (2.0.0.2.el6) is "welcome1".

After you have installed the Oracle Exalytics Release 2.2 Base Image and configured the network on the Exalytics Machine, you must change the root password.

To change the root password:

  1. Log in to the Exalytics Machine as root user.
  2. To change the password, enter the following command:

    # passwd

  3. Enter a new password.
  4. Confirm the password when prompted.

    If the password change is successful, then the following message is displayed:

    passwd: all authentication tokens updated successfully.
    [root]#
    

4.5.2 Creating a Password on the Operating System

For the Oracle Exalytics Release 2.2 Base Image (2.0.0.2.el6), a user named "oracle" and a group named "oinstall" already exists. You next create a password for the user.

To create a password:

  1. Log in as the root user.
  2. To create a password, enter the following command:

    # passwd oracle

  3. Enter the password.
  4. Confirm the password when prompted.

    If the password is created successfully, then the following message is displayed:

    passwd: all authentication tokens updated successfully.
    [root]#
    

    Note:

    To add a different user and group, enter the following commands as root user:

    groupadd <name of the group>

    useradd -g <name of the group> <name of the user>

4.5.3 Assigning User Limits to a New User

User limit is the maximum amount of processors a user can run at the same time. When you add a new user, each user is assigned a low user limit by default. To ensure the new user can run enough processors, you must assign new user limits.

To assign user limits to a new user:

  1. Log on as the root user.
  2. Edit the /etc/security/limits.conf file by adding the following lines:

    <name of the user> soft nproc 131072

    <name of the user> hard nproc 131072

    <name of the user> soft nofile 131072

    <name of the user> hard nofile 131072

4.5.4 Granting User Permissions to the /u01 Directory

Ensure that the user installing the software has permissions to the /u01 drive.

If the user cannot write to the /u01 directory, then, as root user, enter the following commands to change permissions:

chown <name of the user>:<name of the group> /u01

chmod 775 /u01

For example, if the user name is "oracle" and the user group is "oinstall", enter the following commands:

chown oracle:oinstall /u01

chmod 775 /u01

4.5.5 Disabling Security-Enhanced Linux (SELinux) on the 2.0.0.2.el6 Base Image

Disable SELinux after you install Base Image (2.0.0.2.el6) on a Linux 6 operating system.

To disable SELinux

  1. Navigate to and open the /etc/selinux/config file in a text editor.
  2. Edit the file as follows:

    SELINUX=disabled

  3. Save the file.

4.5.6 Verifying Configuration of the Exalytics Machine

Before you install software on the Exalytics Machine, you must run configuration scripts to verify the disk, software, and hardware configurations of the Exalytics Machine.

This section consists of the following topics:

4.5.6.1 Checking Disk Configuration

Check the size of the /u01 disk on the Exalytics Machine. For the X2-4 Exalytics Machine, the size of the disk is approximately 1.7 TB, for the X3-4 Exalytics Machine, the size of the disk is approximately 2.4 TB, and for the X4-4 Exalytics Machine, the size of the disk is approximately 3.5 TB. For the X5-4 Exalytics Machine, the size of the disk is approximately 7.2 TB. For the X6-4 Exalytics Machine, the size of the disk is approximately 7.2 TB.

To check disk configuration:

  1. Log in as root user.
  2. Enter the following command:

    # df -h

    Depending on the configuration of the Exalytics Machine, the following output is displayed:

    • For the X2-4 Exalytics Machine, disk configuration similar to the following is displayed:

      Filesystem Size  Used Avail Use% Mounted on/dev/mapper/VolGroup00-LogVol00
                 447G  4.8G  420G   2% //dev/mapper/VolGroup01-LogVol00

                  99M   25M   70M   27% /boot
      tmpfs      505G     0  505G   0% /dev/shm
      
      [root]#
      
    • For the X3-4 Exalytics Machine, disk configuration similar to the following is displayed:

      Filesystem  Size  Used Avail Use% Mounted on/dev/mapper/VolGroup00-LogVol00
                  729G  4.2G  688G   1%  //dev/mapper/VolGroup01-LogVol00
