PM87662: ABEND 0C4 RSN=00000011 IN BBOASDEG LOADING ECESPRMT FROM IMS RESOURCE ROUTE TABLE DFSRRT

Fixes are available

APAR status

Closed as program error.

Error description

Once we are in BBOASREG, we try to load ECESPRHT,
which is an IMS resource route table (DFSRRT). This is the
specific pointer which is null, and results in an eventual
branch to an invalid address. Because the dependant region is
not finished initialization. This causes the abend 0C4.
 This is a WOLA client routine that performs a WOLA
registration.  In this case it is running in an IMS dependent
region, during an IMS pre-initialization exit.
The call to BBOA1REG is successful if it driven after
dependent region has finished initialization.

The IMS documentation for pre-initialization exits declares
that DL/I calls are not available in these routines.  WOLA is
attempting to make a DL/I call inside of BBOA1REG, and this is
the code that is in error.

The WOLA exit should be modified to check for the presence of
ECESPRHT, and if it is not set, the WOLA registration routine
can be called without using the IMS DL/I call.  For all other
WOLA services, an error return and reason code should be
returned to the caller, stating that this service is not
supported during pre-initialization.  This will avoid the
ABENDS0C4 that is being reported here.

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server V7.0, V8.0, and V8.5                 *
****************************************************************
* PROBLEM DESCRIPTION: An ABENDS0C4 occurs when calling WOLA   *
*                      service BBOA1REG during IMS pre-init    *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
During an IMS pre-initialization exit, an ABENDS0C4 occurs
when WebSphere Optimized Local Adapters service BBOA1REG is
invoked.  The IMS environment is not fully initialized at this
time and a required control block had not been created yet.

Problem conclusion

Code was added to allow BBOA1REG to be called during an IMS
pre-initialization exit.

APAR PM87662 requires changes to documentation.

Tables 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, and 26, in the
topic "Optimized local adapters for z/OS APIs" will be updated
to include the he following reason code information for Return
Code 8:

Reason Code
96

Description
This API cannot be driven during Information Management System
(IMS) initialization or during an IMS pre-initialization exit.

Action
Call this API after IMS initialization is complete.

APAR PM87662 is currently targeted for inclusion in WebSphere
