CQS - Common Queue Server service aids
Use trace records, log records, and utilities to analyze problems in Common Queue Server (CQS).
Diagnosing a CQS related problem
CQS produces SDUMPs for internal errors. The CQS dumps are in the SYS1.DUMP data sets. CQS can also produce LOGREC data set entries for errors.
CQS structure rebuild problems
The most common structure rebuild problem is a rebuild failure. Some environmental situations can occur that cause rebuild to fail.
CQS trace records
Analyze CQS trace records in a formatted dump to determine which function encountered an error, and whether a problem is environmental or internal.
CQS log records
You can use Common Queue Server (CQS) log records to diagnose problems related to the CQS address space and generate various reports, such as statistics about the number of requests.
Printing CQS log records
To print the CQS log records from the z/OS® system log, use the IMS File Select and Formatting Print utility (DFSERA10) with exit routine CQSERA30.
Copying CQS log records for diagnostics
IBM® Software Support sometimes requires a copy of a range of CQS log records for problem determination. You can use the IEBGENER utility program to copy some or all of the CQS log for a structure to a BSAM data set for sending to IBM Software Support.
