MVS system logger availability
CICS® VR checks for the availability of the MVS system logger.
If it detects that the MVS system logger is not available, the following occurs:
- CICS VR issues DWW252I ATTEMPT TO CONNECT TO CICSVR ADDRESS SPACE FAILED.
- CICS VR returns a non-zero return code to VSAM OPEN.
- VSAM OPEN issues IEC161I with reason code 002 and SFI code indicating the reason CICS VR VSAM batch logging was not provided.
- CICS VR sets the condition code to 3999 for this job step.
For all batch jobs that start forward recovery logging, you must set up the batch jobs to detect a 3999 condition code and trigger a backup of your VSAM spheres to ensure recoverability. See Figure 1 for a DFSMShsm example or Figure 2 for a DFSMSdss example.
If there is a problem with the log stream, you might need to delete it and redefine it.
