This section describes how to access PMPC data through SQL interfaces consisting of UDFs. The PMPC UDFs, like the PMPC PM/API requests, are used to monitor system and session‑level performance and set collection and logging rates. However, the PMPC UDFs can be invoked from any application.
The PMPC UDFs provide similar functionality to the PMPC PM/API requests.
Note: When issuing PMPC UDFs, you do not need to fully qualify them by the database name, SYSLIB. They are automatically searched by the DBS in the SYSLIB database.
For examples of PMPC UDFs, see the following topics.
