/TRACE commands

Use the /TRACE commands to direct and to control the IMS™ capabilities for tracing internal IMS events. They also start, stop, and define the activity to be monitored by the IMS Monitor.

The information developed by the LINE, LINK, NODE, UNITYPE, TRANSACTION, PROGRAM, PSB, and TCO keywords is written on the IMS system log (type X'5F' for PSB, and type X'67' records for the other keywords mentioned.) PI (program isolation) and TABLE trace information is kept in storage or logged (type X'67' records), depending on specification of additional keywords. The MONITOR keyword provides no such output on the system log; it only controls the IMS Monitor. The monitor develops its own output data and writes it on a separate data set.

This command can be issued to an IMSplex using the Batch SPOC utility.

The status and options of the current IMS traces can be displayed with the /DISPLAY TRACE command.
