DB2 trace
The DB2® instrumentation facility component (IFC) provides a trace facility that you can use to record DB2 data and events.

Each trace class captures information on several subsystem events. These events are identified by many instrumentation facility component identifiers (IFCIDs). The IFCIDs are described by the comments in their mapping macros, contained in prefix.SDSNMACS, which is shipped to you with DB2.
