Stopping data set support

You can stop the data gatherer from writing to any data set or never activate data set recording. If you do not want the data set support for a data gatherer session, you can do one of the following:
  • Specify the DATASET(STOP) option in the PARM field of the START session command
  • Specify the DATASET(STOP) option in the PARM field of the MODIFY session command
  • Specify the DATASET(STOP) option in an RMF™ Parmlib member
  • Use the default DATASET(STOP).

You can also use the DATASET(STOP) option to suspend recording until you need it. You can activate recording by overriding DATASET(STOP) with DATASET(START) on a session START or MODIFY command.

Example:
Parmlib member ERBRMF04 may contain the following: 
DATASET(STOP)
DATASET(ADD(RMF.DS01))
DATASET(ADD(RMF.DS02))
DATASET(ADD(RMF.DS03))
DATASET(ADD(RMF.DS04))
DATASET(ADD(RMF.DS05))

The DS(STOP) in the member means that no active data set recording occurs when a data gatherer session is started.

To start data set recording later, specify: 
F RMF,S III,DS(START)
or 
F RMF,F III,DS(START)

The DS(START) option on the command overrides the DS(STOP) option in Parmlib member ERBRMF04, and permits the recording of sampled data to the data sets defined by the DS(ADD) options.

If you want, you can also change the data set names specified in the DS(ADD) options.
