CICS® VR checks for the availability of the MVS™ system logger.
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.
