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.
Specifying Network ConnectionsIn general, the DBSERVERNAME and DBSERVERALIASES parameters define dbservernames that have corresponding entries in the sqlhosts file or registry. Each dbservername parameter in sqlhosts has a nettype entry that specifies an interface/protocol combination. The database server runs one or more poll threads for each unique nettype entry.

Specifying Network Connections

In general, the DBSERVERNAME and DBSERVERALIASES parameters define dbservernames that have corresponding entries in the sqlhosts file or registry. Each dbservername parameter in sqlhosts has a nettype entry that specifies an interface/protocol combination. The database server runs one or more poll threads for each unique nettype entry.

The NETTYPE configuration parameter provides optional configuration information for an interface/protocol combination. You can use it to allocate more than one poll thread for an interface/protocol combination and also designate the virtual-processor class (CPU or NET) on which the poll threads run.

For a complete description of the NETTYPE configuration parameter, see the HCL OneDB™ Administrator's Reference.
