There are numerous trace entry points defined inside the listeners and the TRUE that, when used with an IBM socket trace, should offer adequate documentation to troubleshoot problems.
The trace entries are written when TRACE=YES is defined for the listener in SYLSCFG. Trace entries are written to the CSML destination in an abbreviated, high-level format and to the AUX TRACE facility in a more detailed, low-level format. The low-level entries are only accessible through the standard CICS AUX Trace. Due to the high overhead required by tracing, it is recommended that trace be turned on only when trying to trap particular situations.
Following is a high-level trace example:
SYBASE 20:03:17 TRANID SYL2 TSKNO 00031 INITAPI API CALL WAS SUCCESSFUL
