When QMF detects a system or resource error, it writes an entry to the Q.ERROR_LOG table. Errors are logged by user and message number and are date and time stamped. System programmers and troubleshooters refer to error log entries to resolve outstanding QMF problems. You can review and manipulate the error log using the Error Log Facility. The following actions are supported:
Error log entries are stored in Q.ERROR_LOG. For a detailed discussion of this table, see Installing and Managing DB2 QMF for TSO/CICS.
QMF continually inserts entries into the QMF error log table. Review this table for outstanding problems and remove resolved error log entries. If entries are not removed, this table will grow and it will tie up excessive DASD storage.
A well maintained error log table will ensure that you are not wasting critical system resources and that you are resolving outstanding errors.
