This chapter covers some aspects of troubleshooting problems with running applications in an MTO-enabled enterprise server.
Problem diagnosis on an MTO-enabled enterprise server is very similar to problem diagnosis on an enterprise server running Web services or EJB-type services, as described in the chapter Troubleshooting in the Enterprise Server Configuration and Administration Guide.
When you are configuring dumps and traces for an MTO-enabled enterprise server, you might want to select dump on transaction abend; on the ESMAC Control page click Tran next to Dump on ABEND. Dumps created when transactions abend are internally triggered dumps. When you do your data capture, you should include the transaction abend dump, if one exists.
There is a fourth way of obtaining an externally triggered dump: issue an EXEC CICS DUMP command in a CICS program.
On the Trace page of ESMAC, which you see when you request a trace from the Diagnostics group in the menu, the process IDs that appear in the PIDs column can have the following additional prefixes:
3 | 3270 client |
L | CCI listener |
Q | MQSeries listener |
The prefix J for journal control also covers extra-partition transient data
