WHY HGHLVL.REQUESTS IS EMPTY?
Release : 20.0
Component : SYSVIEW Performance Management Option for DB2 for z/OS
IDB2 works with HGHLVL.CDBATREQ which comes with the product. The CDBATREQ contains different REQUESTS/REPORTS that the product needs. However, if one request is customized due to some specific needs or newly created these will go to the HGHLVL.REQUESTS. For this reason you can concatenate up to four(4) datasets so there is no need to change anything in the CDBATREQ. It's normal for HGHLVL.REQUESTS to be empty if no request has been customized and stored there.
