Fix Recommendation

Review the following resources in the JESINPUT resource class:

INTRDR (internal reader for batch jobs)
nodename (NJE node)
OFFn.* (spool offload receiver)
Rnnnn (RJE workstation)
RDRnn (local card reader)
STCINRDR (internal reader for started tasks)
TSUINRDR (internal reader for TSO logons)

Note: If any of the following are not defined within the JES2 parameters, the resource in the JESINPUT resource class does not have to be defined.

-Nodename is the NAME parameter in the NODE statement. Review the JES2 parameters for NJE node definitions by searching for NODE( in the report.
-OFFn, where n is the number of the offload receiver. Review the JES2 parameters for spool offload receiver definitions by searching for OFF( in the report.
-Rnnnn, where nnnn is the number of the remote workstation. Review the JES2 parameters for RJE node definitions by searching for RMT( in the report.
-RDRnn, where nn is the number of the reader. Review the JES2 parameters for reader definitions by searching for RDR( in the report.

Define the JESINPUT resource class to the ACTIVE CLASSES in RACF SETROPTS.

Configure the resources detailed above to be protected by generic and/or fully qualified profiles defined to the JESINPUT resource class.

Examples:
setr classact(jesinput)
setr generic(jesinput)
rdef jesinput intrdr quack(none) owner(admin) audit(failures(read) success(update)) data('Per SRR PDI ZJES0021')
pe intrdr cl(jesinput) id(<syspsmpl>)
pe intrdr cl(jesinput) id(*) /* all users */
