SYS1.LOGREC information

The SYS1.LOGREC data set records various errors that different components of the operating system encounter. For more information about using SYS1.LOGREC records, see the MVS Diagnosis: Tools and Service Aids manual.

WebSphere MQ for z/OS recovery routines write information in the system diagnostic work area (SDWA) to the SYS1.LOGREC data set when retry is attempted, or when percolation to the next recovery routine occurs. Multiple SYS1.LOGREC entries can be recorded, because two or more retries or percolations might occur for a single error.

The SYS1.LOGREC entries recorded near the time of abend might provide valuable historical information about the events leading up to the abend.
