Running Sysview Performance Management Option for Db2 for z/OS (IDB2) IQL reports to find which collections are running in CICS.
What does collection ".............." reference in the reports?
It is possible that the collection name was not supplied and the field displayed is nulls or maybe the records themselves.
Running the BTACTTRL report with a GLOBALS WHERE clause:
where (CONN-TYPE(,4,4) = 'CICS' OR CONN-TYPE(,4,1) = 'CTOR')
Will provide a full display of the record that seems to lack a collection name, which will help determine more about these records.
