Common Service Layer trace

The Common Service Layer trace (CSLT) provides information about the interactions between IMS and the Common Service Layer, including how IMS interacts with the Operations Manager (OM), the Resource Manager (RM), and the Structured Call Interface (SCI).

You can turn on the Common Service Layer trace during online operation by using the /TRACE command. Each trace entry is X'20' bytes long. You can specify trace output destination and tracing volume on the /TRACE command.

If you send the output to the common trace table, you can format the table using the Offline Dump Formatter under IPCS, using either the VERBX command or the IMS Dump Formatter panels. If you send the output to an external data set, you can use the File Select and Formatting Print utility (DFSERA10) with exit routine DFSERA60 to format the trace entries.

To locate the common service layer trace in a dump, look for eye catcher **CSTR.
