DBG55081E The internal INSSEND function error(RC = 028)

Why this error message is generated and how to fix it?.

Environment

Release : 20.0

Component : SYSVIEW Performance Management Option for DB2 for z/OS

Resolution

The DBG55081E error message is the result of attempting to have 2 sessions open to a single Sysview for DB2 Data Collector under TSO, which is not allowed.
 
When the second session is opened the credentials for the first session are removed, since both sessions are for the same Userid and LU name and that is how each User is identified. The DBG55081E error message is essentially saying that you are not signed on to the first session, anymore.
