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™.
Disk, memory, and process management
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.
Multiple listen threadsYou can improve service for connection requests by using multiple listen threads.

Multiple listen threads

You can improve service for connection requests by using multiple listen threads.

If the database server cannot service connection requests satisfactorily for a given interface/protocol combination with a single port and corresponding listen thread, you can improve service for connection requests in the following ways:

By adding listen threads for additional ports.
By adding listen threads to the same port if you have the onimcsoc or onsoctcp protocol
By adding another network-interface card.
By dynamically starting, stopping, or restarting listen threads for a SOCTCP or TLITCP network protocol, using SQL administration API or onmode -P commands.

If you have multiple listen threads for one port for the onsoctcp protocol, the database server can accept new connections if a CPU VP connection is busy.
