Start and stop virtual processors
When you start the database server, the oninit utility starts the number and types of virtual processors that you specify directly and indirectly.
You configure virtual processors primarily through configuration parameters and, for network virtual processors, through parameters in the sqlhosts information.
You can use the database server to start a maximum of 1000 virtual processors.
After the database server is in online mode, you can start more virtual processors to improve performance, if necessary.
While the database server is in online mode, you can drop virtual processors of the CPU and user-defined classes.
To shut down the database server and stop all virtual processors, use the onmode -k command.
