RDz - JES Purge/Cancel Enhanecment

Please enhance RDz to verify the issuer of all job cancel, hold and release functions has RACF ALTER access to the JESSPOOL resource profile for the job prior to issuing any $C, $H or $A JES2 console commands. JES2 only validates that the issuer of $C/$H/$A has authority to issue the command; it doesn't validate that the issuer has authority to modify the job in question. That means any user w/ authority to issue $C/$H/$A console commands has authority to cancel/hold/release any job in the system. That may be sufficient authority for some installations where limited personnel have console access but RDz requires that console access be expanded to all RDz users, which breaks the security provided by restricted console access. These same job resource restrictions are enforced by other spool management products, such as SDSF and IOF. FYI, the format of the JESSPOOL resource to be used in this scenario is: class JESSPOOL profile localnodeid.userid.jobname.jobid.

    This functionality already exists.

    As documented in the Host Reference Guide, Chapter 2 Security Considerations, section JES security, JMON, (RDz's JES Job Monitor) does honor JESSPOOL definitions.

    By default, JMON will only allow actions against jobs owned by the same user (LIMIT_COMMANDS=USERID). Through the FEJJCNFG configuration file, JMON can be instructed to broaden the scope, and rely on JESSPOOL definitions to allow actions against a job. There are 2 modes;
    * LIMIT_COMMANDS=LIMITED will allow a command only if it is explictly permitted by security profiles.
    * LIMIT_COMMANDS=NOLIMIT will allow a command if it is explictly permitted by security profiles, and when the JESSPOOL class is not active.

    An attempt to do an action against a job (owned by someone else) to which you do not have ALTER permit will fail

    JMON
    FEJ222N LIMIT_COMMANDS: 'LIMITED'

    JOBNAME JobID Owner
    BR14ALTR JOB00231 FEJALTER (everyone has full access)
    BR14READ JOB00230 FEJREAD (everyone has read access)
    BR14NONE JOB00229 FEJNONE (nobody has access)
