Thank you both for your responses.  Here’s what Siemens said:

The hospital received a TIF abend at 00:40:26 this morning just as    

CICS was beginning to come down for scheduled maintainence.  The      

abend was a T034 with a return code of 5401.  This indicates that TIF

could not write to the COMQFILE because the control block could not  

be allocated for the system TIF was attempting to write to.  I went  

through the dump and found that TIF was trying to write a record to  

the B3M080AD queue.  System 80 is not in PRCOM so the control block  

could not be allocated for system 80.  There is code in place to      

check for this condition and just issue a message rather then abend  

all of TIF.  I did find these messages numerous times throughout    

the day including just before the abend:                            

00:40:25 ARKE20207: (B3M080) Interface definition not found          

****                                                                

However, since CICS was in shutdown mode I suspect that this code    

was somehow bypassed.                                                

I went in and added system 80 to PRCOM.  When I displayed the        

interface, I found in excess of 57000 records on the system.  This  

appears to be an interface that was used at one time but is currently

de-installed.  However because the TIF tables and triggers are still

there, records are still being generated wasting DASD and possibly    

affecting performance. SSKB# 3088983 talks about removing interfaces  

from the COM SUB that are no longer being used.  Because system 80 is

now in PRCOM though, the problem with the T034 should no longer occur.

I’m not sure exactly what that means (I’m not the Invision or SNA expert), but it sounds a little like what Susan was explaining.  They seem to think this is going to fix our problem, and that’s all I care about.

Susan, it almost sounds like you’ve heard the Openlink comment before  : )
