Issue/Introduction
After falling back DATACOM / DB from V15.x to V14, SYSVIEW does not allow me to see the Data Areas Display We have returned the CAIPARM parameters and restarted CAS9, MUF and ENF, but even so SYSVIEW does not allow reaching the Datacom.
The error message is
"DCOM006E GETDATA request failed, RC 94, RS 26, FC 14"
Environment
z/os, CA Datacom/DB 14.0 and above.
Cause
Site did not follow the fall back procedure when returning back to 14.0.
Especially did not restore CASYSTEMTABLES (DBID 1000).
Resolution
Most likely site has missed the fallback procedure regarding DBID 1000 (CASYSTEMTABLES) .
After falling back Restore DBID 1000 is needed (as well as some other Restore jobs to execute).
