Preventing abends with StopX37/II

StopX37/II attempts recovery on jobs that are abending with B37, D37, or E37 return codes (and many other out-of-space conditions).

These abend codes are associated with disk space availability and management. These codes can be found in even most productive data-processing centers. StopX37/II provides automatic recovery from these abend conditions, which removes a significant burden from your data center support staff.

StopX37/II functions interact with the End-of-Volume SVC, which is a part of the z/OS operating system. Before the operating system invokes the module that produces the return codes, StopX37/II employs user-defined filtering language to decide whether to attempt recovery before the job abends.

For a sequential data set to be multivolume, the data set must already be cataloged. If a job uses all 16 extents that are available to a sequential data set, StopX37/II functions can dynamically allocate and add new volumes to the data set’s catalog entry. The sequential data set then becomes a multivolume data set.

Your data center might not want StopX37/II to attempt recovery for all B37, D37, E37, or other errors. The decision to attempt recovery for a particular job can be based on many considerations, including job name, job class, account number, data set name, IBM RACF group, and so on.

By using a full screen ISPF interface, you can specify filtering criteria to select which jobs will be recovered. After a job has been selected, you can use the ISPF interface to apply a rule list to the job to determine the specific parameters of the recovery action to be taken.

A complete audit trail is provided by way of the JOBLOG/SYSLOG and SMF data sets. Batch reporting utilities are provided to scan SMF data for statistics about recovery attempts and actions that were taken.

StopX37/II functions offer specific methods for tailoring the product to attempt recovery for user-directed abend conditions. StopX37/II will not take over your system and attempt to recover all abend conditions. After StopX37/II has been installed and tested, you need to decide which types of jobs merit a recovery attempt.
