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 : )
