DFSAOUE0 exit abend 0F8

Question & Answer


Question

Why is DFSAOUE0 exit seen in an IMS S0F8 abend during DLI call in MPP (Messaging Processing Program)?

Answer

DFSAOUE0 is an exit in AF/Operator for OMEGAMON for IMS. There are a couple of things to check:

1) Are you using AF/Operator? Check to see all service has been applied:

     APAR OA30938 - ABEND 0F8 USING DFSAOUE0 IMS EXIT DRIVER PROGRAM
     PTF  UA50928 - CLOSED 01/05/2010
     Description  - An abend 0F8 can occur when using the DFSAOUE0 IMS exit driver program if it is entered in cross-memory mode.
     SUP BY UA60111 (APAR OA36272)...
         VARIOUS IMS ABENDS AFTER APPLYING UA57543 

Here is a link to the latest service: http://www.ibm.com/support/docview.wss?uid=swg21701211

2) If you are not using AF/Operator, then to fix the problem you need to remove the AF/Operator version of DFSAOUE0 from your IMS RESLIB. You need to beware of just removing DFSAOUE0 as there may be another vendor's exit built into it that you may still require or possibly you have had another DFSAOUE0 earlier in the RESLIB concatenation that you recently deleted and this old one suddenly became activated?

Check your RESLIB concatenation by looking for DFSAOUE0. By browsing any DFSAOUE0 module, locate the one with the AKOG320 eyecatcher?

If it is located, next confirm if there's another vendor using this exit by running AMBLIST. (AMBLIST maps load modules and program objects.):
//COPY EXEC PGM=AMBLIST
//SYSPRINT DD SYSOUT=
//STGLIB DD DISP=SHR,DSN=hlq..LOADLIB
//SYSIN DD

LISTLOAD OUTPUT=XREF,DDN=STGLIB,MEMBER=DFSAOUE0
/*

The AKOG340 version I have has a size of 00000A78, if it's close to that size then it's likely there's no other version of the exit incorporated and you can safely delete it using ISPF.
