Allowing for IRLM trace output printing

To provide a trace of the activity occurring in the IRLM subsystem, you use the z/OS® Component Trace facility or the TRACE=YES option of DXRJPROC, the IRLM procedure.

CTRACE records

IRLM produces trace output in z/OS component trace (CTRACE) format. This allows you to use IPCS CTRACE format, merge, and locate routines to process the buffer data. Both the IRLM trace buffers in the dump and external writer data set can be formatted using IPCS. The IRLM trace formatting load module (DXRRLFTB) and buffer find routine load module (DXRRL186) must be available for IPCS.

Arranging for formatted dump output

IRLM uses the SDUMP facility of z/OS. The offline printing of dump output is done using z/OS print dump.
