Note that there is no jobname qualifier on the JES2.CANCEL.BAT profile. This is 
why SDSF has the extra JESSPOOL profile check that goes beyond vanilla JES2 
cancel command security.

This extra check is ONLY performed inside SDSF and is made before we build the 
operator command text.

Coincidentally I gave a presentation at virtual GSE today entitled "SDSF 
Security - How does it work under z/OS 2.5?" and the sequence of SAF checks is 
described with a few examples.

If you want, I can forward you the slide deck.

Okay, so not sure I reall understand the way this works?

Under jesspool, checks nodeid.userid.jobname.jobid, so I could add my cics 
jobname like C30TCI* here? Is this the SDSF command like C, P etc?

Or under OPERCMDS I have

JES2.CANCEL.BAT.C30TCI* (G)
JES2.CANCEL.BAT.** (G)

And now.

MVS.CANCEL.BAT.C30TCI*.* (G)
MVS.CANCEL.** (G)

Where does the granularity take place, for certain jobs??

I want the users to be able to cancel some batch jobs and everything they 
submitted, but not CICS, DB2 or other system things.

Note that one of the "value add" functions of SDSF is that it can check for 
ALTER access to the JESSPOOL profile for the owner and jobname for destructive 
actions like "C" and "P".

Does not stop them using freeform "slash" to issue the raw operator command, 
but removes the convenience of the action character.

Hi Ms. Terri,

The OPERCMDS JES2.CANCEL.** profiles protect the JES2 ($C...) cancel command.
I believe you also need to use the OPERCMDS MVS.CANCEL.STC.mbrname.id profile 
to protect the MVS CANCEL command.

So in your case, that would be something like this: (if your running CICS as an 
STC!)
MVS.CANCEL.STC.C30TCI* (G)
MVS.CANCEL.STC.** (G)

Subject: RACF - SDSF question

Hi,
I know there is a RACF group, but hopefully this is simple and I am just 
missing something I have done 100 times over with no issues.

We run our CICS regions as batch jobs, and I just found out a user instead of 
them issuing a CEMT PERF SHUT command, they are canceling it.

Which then causing a 100 vsam messages on startup with all the verifies, and if 
something goes wrong they call me...

So I tried to stop this habit, I know they are putting a C beside the CICS and 
a $CJ(xxxxx) command

So I have 2 rules in RACF under OPERCMDS

JES2.CANCEL.BAT.C30TCI* (G)
JES2.CANCEL.BAT.** (G)

If I restrict the BAT.** then they cant cancel even their own batch jobs, So I 
always thought more specific is looked at first?

One of my previous co-workers implemented SDSF-RACF rules converted from 
ISFPARMS.

Lastly, I understand this doesn't stop them from canceling any other jobs, but 
since this is a development shop we allow more access than most.

But I don't want users canceling a CICS or DB2 etc.

Any ideas how they are getting the access and not stopped with the more 
specific rule??
