Fix Recommendation

Configure access authorization for resources defined to the JESINPUT resource class to be restricted to the appropriate personnel.

Grant read access to authorized users for each of the following input sources:

INTRDR
nodename
OFFn.*
OFFn.JR
OFFn.SR
Rnnnn.RDm
RDRnn
STCINRDR
TSUINRDR and/or TSOINRDR

The resource definition will be generic if all of the resources of the same type have identical access controls (e.g., if all off load receivers are equivalent). The default access will be NONE except for sources that are permitted to submit jobs for all users. Those resources may be defined as either NONE or READ.
