Using the AMP JCL DD parameter to enable VSAM Batch Logging
If do not want to update the catalog entry of a VSAM sphere to
enable batch logging, you can specify FRLOG in the AMP parameter on the JCL
DD statement of the VSAM data set in the batch job.
You can also override the FRLOG catalog setting of a VSAM data
set by specifying FRLOG in the AMP parameter. You can set FRLOG in the AMP
parameter to one of the following values:
AMP=('FRLOG=ALL | NONE | REDO | UNDO')
Note: If
ALL or REDO is specified for FRLOG, a LOGSTREAMID must also be specified.
