Using IDCAMS DEFINE CLUSTER

You can use the IDCAMS DEFINE utility to create a VSAM data set and enable batch logging.

You can set the FRLOG value to one of the following values:
FRLOG(ALL | NONE | REDO | UNDO)
Note:
  1. See Enabling CICS VR VSAM batch logging for a description of the parameters.
  2. If ALL or REDO is specified for FRLOG, a LOGSTREAMID must also be specified.
  3. If you omit the FRLOG parameter when defining a VSAM cluster, a value of NULL is assumed.
