If I remember correctly the NMCMDUDC checks if NBDISABLE=FATAL is set and passes the command to the MPE purge if it is. Also be careful about unsetting your system catalog!! This will make you vulnerable during this execution and it means the system level logon UDC will not be set. Any users that logon will likely not get the proper environment depending on how your system is setup. Plus if the job stream crashes before it resets the catalog you will be left without it until you re-set it manually. There are so many reasons why setting the catalog is not a good solution to this problem.
I have used the Netbase/MPE command interface and the MPEX/Netbase command interface and both work very well when setup correctly. They do allow you to purge files on the master or shadow and the file command is applied to both systems. I think you need NFA in order to execute the commands on the shadow.
We need more information about the error you are getting in order to understand what this problem is. I believe the MPEX command YESPURGE bypasses the Netbase interface so using this will likely solve the problem without looking further into the Netbase interface issue.

Raymond,
I think we just unset the catalog to get around this (i.e. if showcatalog
;user=manager shows sysudc.pub.sys and nmcmdudc.pub.netbase, do a
setcatalog sysudc.pub.sys;system). Do the purge and then setcatalog back
(i.e. setcatalog sysudc.pub.sys,nmcndudc.pub.netbase;system)
OR
You might get away with a setjcw nbdisable=fatal, but this is doubtful as I
think this has no effect on the UDC in effect. If you do try this, make
sure you set it back when finished trying your purge with setjcw
nbdisable=0.
HTH

Hello.
I am trying to select files for purge using the MODDATE file attribute in
MPEX. I want to do this in a job. From a session, the command works for
LISTF, but not for PURGE. I am thinking this is due to the NetBase UDC. I
think I did this a while back, so there must have been a workaround, but I
can't remember (this happens way too often, lately). Any ideas?
%LISTF FILE####.PUB.SYS(MODDATE<TODAY-120)
%PURGE FILE####.PUB.SYS(MODDATE<TODAY-120)
Thanks.
Ray
