Administration Commands For COD

Let's continue from previous post of capacity of demand. Well, we will discuss that what all steps are required to increase CPU cores in Database Machine as a part of COD.

Step-1 Verify the number of active physical cores using the following command

DBMCLI> LIST DBSERVER attributes coreCount

Step-2 Use the following command to increase the number of active physical cores:

DBMCLI> ALTER DBSERVER pendingCoreCount = new_number_of_active_physical_cores

Step-3 Verify the pending number of active physical cores using the following command:

DBMCLI> LIST DBSERVER attributes pendingCoreCount

Step-4 Restart the server

Step-5 Verify the number of active physical cores using the following command:

DBMCLI> LIST DBSERVER attributes coreCount

The database server must be restarted after enabling additional cores. 

If the database servers are part of a cluster, then they can be enabled in a rolling fashion. 

Following table shows the Capacity On Demand core processor configuration for database machine.
