Virtual processors and threadsThese topics describe virtual processors, explain how threads run within the virtual processors, and explain how the database server uses virtual processors and threads to improve performance.
Virtual processor classesEach class of virtual processor is dedicated to processing certain types of threads.
Communications support module virtual processorThe communications support module (CSM) class of virtual processors performs communications support service and communications support module functions.

Communications support module virtual processor

The communications support module (CSM) class of virtual processors performs communications support service and communications support module functions.

The database server starts the same number of CSM virtual processors as the number of CPU virtual processors that it starts, unless the communications support module is set to GSSCSM to support single sign-on. When the communications support module is GSSCSM, the database server starts only one CSM virtual processor.

The database server starts the same number of CSM virtual processors as the number of CPU virtual processors that it starts.

For more information about the communications support service, see Client/server communication.
