How do I troubleshoot failure of "Alloc" Clist within Rexx exec?

[IDC3044]

Mainframe Environment - z/OS R1.2

I have coded a Rexx exec to run as the last step of a batch job. This exec checks to see if the previous step wrote anything to the SYSMDUMP dataset. If it has been written to it is copied to a cartridge GDG for retention.
When I test this exec in a batch job under my ID and issue the TSO Clist Alloc I process as expected. When I try to run using the USERID assigned to the Production job I receive the following RC(12):

32 *-* "ALLOC FI(SYSUT2) DS('"GDGNUM"')SHR EXPDT(98000)"
>O>"ALLOC FI(SYSUT2) DS('IDMSR.DOCIDMSE.DUMPGDG.G0036V00') SHR EXPDATE(98000)"
+++ RC(12)

I cannot see any error messages in SYSLOG that might help clarify.

What method can I use to find out why the allocation fails?

There should be a message issued if RC(12). Did you check the SYSOUT for the JOB? If you can't find an error message, it could be that you have MSG turned off.

msgstate = MSG("ON") /* preserve current setting */
"ALLOC ...."
$z = MSG(msgstate)  /* restore msgstate */

Update from Message Poster - I set MSGSTATE = MSG('ON') with no additional messages appearing.

(grumble grumble...) Does your profile say WTPMSG or NOWTPMSG? (grasping at straws...)

As it turns out the problem was related to the fact that the ID I was attempting to use was not a valid TSO ID. It is a valid RACF ID, but is not ever used to logon. I changed my tack and got the desired results. Thanks for the help.
