How You Send Trace Data to an Output File

Trace data that has been collected in the internal trace table can also be sent to a MIMTRACE data set rather than to a SYSOUT class. To tell CA MIM to write trace records to a data set, specify a ddname of MIMTRACE and a data set name on the DSNAME parameter.

MIMTRACE data sets should be preallocated with these attributes:

• RECFM=FB or FBA
• LRECL=121
• BLKSIZE=multiples of 121

Include a DD card image in your startup procedure to define MIMTRACE, if you want to route trace data to a data set. You can also use the ALLOCATE command to dynamically allocate a data set for tracing.

For example:

ALLOCATE DDNAME=MIMTRACE DSNAME=MIM.TRACE

Alternatively, use an ALLOCATE command for the MIMTRACE ddname in the MIMINIT member.
