Fix Recommendation

Ensure the following items are in effect:

-The JES2. resource is owned in the WRITER resource class.

For Example:
The following command may be used to establish default protection for resources defined to the WRITER resource class:
TSS ADDTO(deptacid) WRITER(JES2.)

-The ownership of all WRITER resources is appropriate.

Grant read access to authorized users for each of the following WRITER resource class output destinations:

JES2.LOCAL.devicename
JES2.LOCAL.OFF*.JT
JES2.LOCAL.OFF*.ST
JES2.LOCAL.PRT*
JES2.LOCAL.PUN*
JES2.NJE.nodename
JES2.RJE.devicename

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

TSS PERMIT(jesopracid) WRITER(JES2.LOCAL.OFF*.ST) -
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 transmitters are equivalent).

Check Contents

Refer the JES2PARM member of SYS1.PARMLIB
Review the WRITER resource in the JESINPUT resource class:

NOTE: If the WRITER resource is not defined within the JES2 parameters, the resource in the JESINPUT resource class does not have to be owned.

From the ISPF Command Shell enter:
TSS WHOOWNS JESINPUT(WRITER)

If the WRITER resource is owned by generic and/or fully qualified entries in the JESINPUT resource class, this is not a finding.
