2.11.8.2 Configuring Eighth Rack On X3-2 Machines Running Oracle Exadata Storage Server Release 12.1.2.2.3 or Earlier

The following procedure should be performed after Oracle Linux database server in Oracle Exadata Database Machine Eighth Rack has been re-imaged, restored, or rescued.

1. Copy the /opt/oracle.SupportTools/resourcecontrol utility from another database server to the /opt/oracle.SupportTools/resourcecontrol directory on the recovered server.
2. Ensure proper permissions are set on the utility.

   # chmod 740 /opt/oracle.SupportTools/resourcecontrol
   

3. Verify the current configuration.

   The output from the command is shown in this example.

   # /opt/oracle.SupportTools/resourcecontrol -show
   
     Validated hardware and OS. Proceed.
     Number of cores active: 8
   

   For an eighth rack configuration, eight cores should be enabled. If that value is shown, then no configuration changes are necessary. If that value is not shown, then continue to step 4 of this procedure.

   Note:

   If there is an error similar to the following after running the utility, then restarting the server one or more times usually clears the error:

   Validated hardware and OS. Proceed.
   Cannot get ubisconfig export. Cannot Proceed. Exit.

4. Change the configuration for enabled cores.

   # /opt/oracle.SupportTools/resourcecontrol -cores 8
   

5. Restart the server.

   # shutdown -r now
   

6. Verify the changes to the configuration.

   # /opt/oracle.SupportTools/resourcecontrol -show
   

   The following is an example of the expected output from the command for the database server:

   This is a Linux database server.
   Validated hardware and OS. Proceed.
   Number of cores active per socket: 4
