Examining the LOGREC buffer

Use the IPCS subcommand VERBEXIT LOGDATA to view the LOGREC buffer in a dump. This report might repeat much of the information contained in the STATUS FAILDATA report, but it helps to identify occasions when multiple error events caused the software failure.

The example in Figure 1 shows how multiple errors can appear in the LOGREC buffer. Abend X'0D5' is the first abend and X'058' is the second. Always check for multiple errors in the VERBEXIT LOGDATA report that are in the same address space or a related address space and are coincident with or precede the SVC dump.

When viewing the VERBEXIT LOGDATA report, skip the hardware records to view the software records. Search for the first software record.

The field “ERRORID=” gives the error identifier for the software failure. The error identifier consists of the sequence number, ASID, and time of the abend. By matching this identifier with error identifiers from other reports, you can tell if this is the same abend you have been analyzing or if it is a different abend. See Interpreting software records for more information.
