Add virtual processors in online mode with onmode

Use the -p option of the onmode command to add virtual processors while the database server is in online mode.

Specify the number of virtual processors that you want to add with a positive number. As an option, you can precede the number of virtual processors with a plus sign (+). Following the number, specify the virtual processor class in lowercase letters. For example, either of the following commands starts four additional virtual processors in the AIO class:
onmode -p 4 aio

onmode -p +4 aio

The onmode utility starts the additional virtual processors immediately.

You can add virtual processors to only one class at a time. To add virtual processors for another class, you must run onmode again.
