Manage virtual processorsThese topics describe how to set the configuration parameters that affect database server virtual processors, and how to start and stop virtual processors.
Start and stop virtual processorsWhen you start the database server, the oninit utility starts the number and types of virtual processors that you specify directly and indirectly.
Add virtual processors in online modeWhile the database server is running, you can start additional virtual processors for some virtual processor classes with the -p option of the onmode utility.
Add network virtual processorsWhen you add network virtual processors, you add poll threads, each of which requires its own virtual processor to run.

Add network virtual processors

When you add network virtual processors, you add poll threads, each of which requires its own virtual processor to run.

In the following example, the poll threads handle a total of 240 connections:

NETTYPE ipcshm,4,60,CPU # Configure poll thread(s) for nettype

For ipcshm, the number of poll threads correspond to the number of memory segments. For example, if NETTYPE is set to 3,100 and you want one poll thread, set the poll thread to 1,300.
