For the Oracle Exalytics Release 2 Base Image (2.0.0.0.el5 or 2.0.0.0.el6), a user named "oracle" and a group named "oinstall" already exists. You next create a password for the user.
To create a password:
Log in as the root user.
To create a password, enter the following command:
# passwd oracle
Enter the password.
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>
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:
Log on as the root user.
Edit the /etc/sysconfig/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
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
Disable SELinux after you install Base Image (2.0.0.0.el6) on a Linux 6 operating system.
To disable SELinux
Navigate to and open the /etc/selinux/config file in a text editor.
Edit the file as follows:
