SYSVIEW Performance Management Option for DB2 for z/OS

Issue/Introduction

In the Sysview MVS monitor option 6 (DB2 option), any selection to view a specific Db2 subsubstem's metrics always reverts back to the first subsystem
defined.  After selecting a subsequent Db2 ssid from the Db2 list, the information provided always reverts back to the first Db2 subsystem that was
selected. The Sysview Performance Management Option for Db2 for z/OS (IDB2) data collector job shows:

(rc 204) Xnet request failed (rs 273) Xnet Duplicate Agent

Cause

The  (rc 204) Xnet request failed (rs 273) Xnet Duplicate Agent error condition was caused by the IDB2 ssidSYSP members having an erroneous
XNETID=0000 coded in them.  The default XNETID parameter in the ssidSYSP member(s) should be kept commented out (as shipped) to allow the
identification string to be uniquely built.  This will alleviate the (rs 273) Xnet Duplicate Agent error condition.

Resolution

The XNETID=0000 statement that was added by the customer in the IDB2 ssidSYSP member(s) was deleted, and the IDB2 data collectors were recycled.
The Sysview MVS monitor option 6 (DB2 option) now provided metrics for all of the Db2 subsystems being monitored by the correlating IDB2 data collector.
