DB2_SUBSYSTEM
Use the DB2_SUBSYSTEM parameter in CQM@WDB2 to control the offload of data to the Performance History Database.
- Description
- The target Db2® subsystem to which you want to offload
Performance History Files.
If you use the DB2_SUBSYSTEM parameter, you must also specify the INTERVAL_DSN parameter to specify the interval data set name from the source Query Monitor Subsystem.
The Query Monitor Subsystem associated with the source Performance History Files does not need to be running to perform the offload. To perform an offload to an alternate Db2 subsystem on the same LPAR as the Query Monitor Subsystem, only the DB2_SUBSYSTEM parameter is required.
Either relative or a specific range of intervals can be offloaded. For a relative interval range, the -1 interval is considered to be the last written interval that is contained in the interval data set.
