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.
Encrypt virtual processorsUse the VPCLASS configuration parameter with the encrypt keyword to configure encryption VPs.

Encrypt virtual processors

Use the VPCLASS configuration parameter with the encrypt keyword to configure encryption VPs.

If the encrypt option of the VPCLASS parameter is not defined in the onconfig configuration file, the database server starts one ENCRYPT VP the first time that any encryption or decryption functions defined for column-level encryption are called. You can define multiple ENCRYPT VPs if necessary to decrease the time required to start the database server.

To add five ENCRYPT VPs, add information in the onconfig file as follows:

VPCLASS encrypt,num=5

You can modify the same information using the onmode utility, as follows:

onmode -p 5 encrypt

For more information, see the configuration parameters and the onmode utility topics in the HCL® OneDB® Administrator's Reference. For more information about column-level encryption, see the HCL OneDB Security Guide.
