Fix Recommendation

The JES2. resource must be owned in the OPERCMDS class.

NOTE: JES2 is typically the name of the JES2 subsystem. Refer to the SUBSYS report and locate the entry with the description of PRIMARY JOB ENTRY SUBSYSTEM. The SUBSYSTEM NAME of this entry is the name of the JES2 subsystem.

Extended MCS support allows the installation to control the use of JES2 system commands through the ACP. These commands are subject to various types of potential abuse. For this reason, it is necessary to place restrictions on the JES2 system commands that can be entered by particular operators. To control access to JES2 system commands, the following recommendations will be applied when implementing security:

For Example:
The following command may be used to establish default protection for JES2 system commands defined to the OPERCMDS resource class:

TSS ADDTO(deptacid) OPERCMDS(JES2.)

Check Contents

From the ISPF Command Shell enter:
WHOOWNS OPERCMDS(JES2)
NOTE: JES2 is typically the name of the JES2 subsystem. Refer to the SUBSYS report and locate the entry with the description of PRIMARY JOB ENTRY SUBSYSTEM. The SUBSYSTEM NAME of this entry is the name of the JES2 subsystem.

If the JES2. resource is not owned, or is owned inappropriately, in the OPERCMDS class, this is a finding.
