CQS log recovery

CQS uses a z/OS® log stream for its recovery log. You cannot recover if the last offload data set in the z/OS log stream is full and CQS fails. Be sure to schedule CQS system checkpoints frequently enough to prevent your offload data sets from filling. You can define groups of offload data sets for the system log, and z/OS uses each group in turn so that you do not run out of data sets. CQS can recover your system by using these data sets.
