Diagnostic trace for the IRLM

You can control diagnostic traces for the IRLM using z/OS commands.

MODIFY irlmproc,SET,TRACE: Dynamically sets the maximum number of trace buffers for each trace type. IRLM uses this value only when the external component trace writer is not activated.
MODIFY irlmproc,STATUS,TRACE: Displays the status of traces and the number of trace buffers that are used for each trace type. Also displays indication of whether the external component trace writer is active for the trace.
START irlmproc,TRACE=YES: Captures traces in wrap-around IRLM buffers at IRLM startup.
TRACE CT: Starts, stops, or modifies a diagnostic trace for IRLM. The TRACE CT command acts independently of traces that are started automatically during IRLM startup.

Recommendations:

Do not use the external component trace writer to write traces to the data set.
Activate all traces during IRLM startup. Use the following command to activate all traces:
```
START irlmproc,TRACE=YES
```
