AdministeringIn addition to administering the database server, you can tune performance, replicate data, and archive data.
System administrationThese topics contain concepts, procedures, and reference information for database and database server administrators to use for managing and tuning HCL OneDB™ database servers.
Administrator's GuideThe HCL OneDB™ Administrator's Guide provides the information required to administer HCL OneDB™.

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.
Network virtual processorsA client can connect to the database server in the through following ways: a network connection, a pipe, or shared memory.
Specify the number of networking virtual processorsEach poll thread requires a separate virtual processor, so you indirectly specify the number of networking virtual processors when you specify the number of poll threads for an interface/protocol combination and specify that they are to be run by the NET class.

Specify the number of networking virtual processors

Each poll thread requires a separate virtual processor, so you indirectly specify the number of networking virtual processors when you specify the number of poll threads for an interface/protocol combination and specify that they are to be run by the NET class.

If you specify CPU for the vp class, you must allocate a sufficient number of CPU virtual processors to run the poll threads. If the database server does not have a CPU virtual processor to run a CPU poll thread, it starts a network virtual processor of the specified class to run it.

For most systems, one poll thread and consequently one virtual processor per network interface/protocol combination is sufficient. For systems with 200 or more network users, running additional network virtual processors might improve throughput. In this case, you must experiment to determine the optimal number of virtual processors for each interface/protocol combination.
