Startup of Sysview Performance Management Option for Db2 for z/OS (IDB2) Data Collector fails with
DBG37034E Data Collector unable to allocate thread using plan name IDBSxxxx and authorization id <userid>.
The IDB2 Data Collector <userid> was never granted execute authority on the IDB2 r20 IDBSPLAN entry (in this case the plan name was IDBSxxxx).
Running the following GRANT statement:
GRANT EXECUTE on PLAN IDBSxxxx to <userid> (the IDB2 Data Collector userid) proved corrective.
