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: - See Enabling CICS VR VSAM batch logging for a description of the parameters.
- If ALL or REDO is specified for FRLOG, a LOGSTREAMID must also be specified.
- If you omit the FRLOG parameter when defining a VSAM cluster, a value
of NULL is assumed.
