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.

Note 1: Nodename is the NAME parameter in the NODE statement. Review the JES2 parameters for NJE node definitions by searching for "NODE(" in the report.

Note 2: 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.

Note 3: 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.

Note 4: RDRnn, where nn is the number of the reader. Review the JES2 parameters for reader definitions by searching for "RDR(" in the report.

Ensure all of the defined resources above are owned by generic and/or fully qualified entries in the JESINPUT resource class.

For Example:

The following commands may be used to establish default protection for resources defined to the JESINPUT resource class:

TSS ADDTO(deptacid) JESINPUT(OFFn.)

Grant read access to authorized users for each of the resources defined to the JESINPUT resource class.

The following is an example of granting operators with a profile ACID of jesopracid permission to restore jobs into any SPOOL off load processor after obtaining permission from the ISSO:

TSS PERMIT(jesopracid) JESINPUT(OFF*.) ACCESS(READ) ACTION(AUDIT)

The resource definition should be generic if all of the resources of the same type have identical access controls (e.g., if all off load receivers are equivalent).

From the ISPF Command Shell enter:

TSS WHOOWNS JESINPUT(*)
If all of the resources above are owned by generic and/or fully qualified entries in the JESINPUT resource class, this is not a finding.

If any of the above resources are not owned, or are owned inappropriately, in the JESINPUT resource class, this is a finding.
