Re: EXEC PGM=??? to issue operator commands from the JCL stream?

[Bond, Richard]

Good example of why this facility should be disabled for batch jobs (JES2 - 
JOBCLASS(*)  COMMAND=IGNORE,).   We had a DB2 job that wanted to 
'quiesce' something in DB2 (sorry, I'm not a DB2 person so I don't remember 
what the 'something' was).  Anyway, the JCL should have said //* QUIESCE 

but the '*' was mistakenly omitted which resulted in the LPAR being quiesced.

That depends on the software that you're running and on how it's
configured. There are several flavors of in-stream commands and there are
facilities for issuing commands from within REXX. My preference is to use
the CONSOLE facility in REXX and retrieve the command output.

You need to discuss your requirements with your systems and security
staffs. If they support more than one option, you'll need to determine
which best suits your needs.

I would think that this would be unnecessary, if the OPERCMDS and JESSPOOL

I agree. We don't allow users to use "// COMMAND " but they can use the
JCL shown by John McKown in his post:

//DOCMDS EXEC PGM=IEBGENER
//SYSPRINT DD SYSOUT=*
//SYSIN DD DUMMY
//SYSUT2 DD SYSOUT=(*,INTRDR)
//SYSUT1 DD DATA,DLM='$$'
/*$VS,'D A,L'
$$
Security wise, JES2 does a third party REQUEST=AUTH UTOKEN=user_token where
the user_token is the address of the submitter's RACF token to see if they
have CONTROL access to the OPERCMDS profile "JESx.VS" for the $VS JES2
command.

 Then JES2 does a second party REQUEST=AUTH ACEE=user_acee_address where the
submitter's ACEE is used to check to see if the user has READ authority to
OPERMCDS profile "MVS.DISPLAY".

A couple shops I've been in have disabled issuing commands 
through JCL, but already had a program that issued commands.  
In both cases the program did security validation before issuing
the commands.

I think that is a pretty common situation.   The details are different

If your site has restrictions on entering Commands via inline jcl or Console is 
not authorized for REXX, the other option is to 
write your own MGCR or MGCRE assembler program to read and process commands.  
This method would require your program to be APF authorized and you would need

Also, if the only purpose of the job is to execute commands, the JOB and
EXEC cards are not needed. In my shop, a pds member with just these two records:

/*$VS,'D A,L'
/*$VS,'D T'

can be successfully submitted.

Re: EXEC PGM=??? to issue operator commands from the JCL stream?

[Roger Bolan]

On my JES2 system, nothing special is needed.  To issue commands that do 
not have to coordinate with job steps, you can just stick them at the top 
of any job. 

For example, when running a testcase that requires me to use a special 
writer proc and destination for a certain printer, I can just insert the 
following lines right above my job card: 

/*$PPRT619 
/*$T FSSDEF(WTRES600),PROC=WTRESRJB 
/*$TPRT619,ROUTECDE=RJB619 
/*$SPRT619 

That stops PRT619, changes the proc, changes the routecde (for DEST), and 
then starts the printer for me.

Since those commands are not synchronized with the job steps, I have a 
separate similar job with an IEFBR14 step to put the printer back to the 
original values.

Re: EXEC PGM=??? to issue operator commands from the JCL stream?

[Jon Brock]

We use a program from the CBT tape for this very thing.  

Todd's original need has been satisfied for the moment, as he didn't
need to synchronize commands within a job stream.  Even so, I prefer to
use the program, as differing security parameters at our installation
mean the IEFBR14 method works on the development system but not in
production.

I can't remember exactly which file had the program we use, but I know
it was one from CBT.

$VS is a JES2 command which basically tells JES2 to issue an MVS command.
Although it is issued by the JES2 address space, the command is processed as
if it were issued by the RACF id under which the job is executing.

This is documented somewhere in the JES2 manuals. Of course, I'm being a bit
parochial in assuming a JES2 system.

Thanks to everyone. 

I implemented Raymond's suggestion for // COMMAND 'blah' last night, and it
works great.  The unsynchronized behavior is fine for the immediate need at
hand.  I needed to refresh WLM.

John, do you have an example of an IEFBR14 job that would do this?  

I've used PGM=COMMAND before - I wasn't sure of the origin... probably the
CBTTAPE.

Again, thanks all.

The simplest way, but which requires that the INTRDR be set up correctly, is
to do something like:

//DOCMDS EXEC PGM=IEBGENER
//SYSPRINT DD SYSOUT=*
//SYSIN DD DUMMY
//SYSUT2 DD SYSOUT=(*,INTRDR)

Re: EXEC PGM=??? to issue operator commands from the JCL stream?

[J R]

It depends if you want the commands synchronized 
with a particular step, or not.  
 
If you don't require step synchronization, you can 
simply include the commands in the JCL, either 
directly or as operands of the COMMAND statement.  
 
However, if you do require step synchronization, you 
will need a program.  Check the CBT tape.
