Db2-supplied user tables

You or certain tools might create user tables that are supplied with Db2 on your Db2 for z/OS® subsystem.

Supplied user tables enable you to capture information about data access by using the EXPLAIN function, to monitor query and system performance with monitor profiles, and to limit the use of resources by particular applications or middleware servers by using the resource limit facility. Instances of these tables also enable optimization tools to capture, analyze, and store information about query performance.
