Setting up the external trace environment

You can request external tracing by starting traces with the OUT option, or by entering the /TRACE SET ON TABLE xxxxx OPTION LOG command to start the trace with the LOG option.

You can start certain traces at IMS initialization with these methods:

• For online systems, specify the appropriate trace keywords on the OPTIONS statement in the DFSVSMxx member of the IMS PROCLIB data set.
• For a batch environment, specify the appropriate trace keywords on the DFSVSAMP DD statement.

You can also turn tracing off or on by using the /TRACE command.

See DFSVSMxx member of the IMS PROCLIB data set for more information.
