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.
XML virtual processorAn XML virtual processor is required to perform XML publishing.

XML virtual processor

An XML virtual processor is required to perform XML publishing.

When you run an XML function, an XML virtual processor is created automatically.

An XML virtual processor runs one XML function at a time. To run multiple XML functions simultaneously, create additional XML virtual processors.

Use the VPCLASS configuration parameter with the IDSXMLVP keyword to configure XML virtual processors. For example, to add five XML virtual processors, add the following line to the onconfig and restart the database server:

VPCLASS idsxmlvp,num=5

You can dynamically add XML virtual processors by using the onmode -p command, for example:

onmode -p 5 idsxmlvp

For more information about the VPCLASS configuration parameter and the onmode utility, see the HCL OneDB™ Administrator's Reference. For more information about XML publishing, see the HCL OneDB Database Extensions User's Guide.
