APAR status

Closed as program error.

Error description

There is a timing window that can occur when a BBOC STOP_SRVR
is done causing an ABEND301.  In this case, the unregister does
not complete, and the following errors happen for
register/unregister commands issued after this:

BBOA8103E An error occurred during register with return code 8
and reason code 8.

BBOA8100E An error occurred during Unregister with return code
8 and reason code 82

* PROBLEM DESCRIPTION: An ABEND301/ABENDS301 occurrs in the    *
*                      client process after calling the WOLA   *

****************************************************************
An ABEND301/ABENDS301 can occur when the WebSphere Optimized
Local Adapters (WOLA) unregister API (BBOA1URG) is driven to
forcibly terminate a registration.  The unregister API will
close all connections used by the WOLA registration.  A task in
the client process can be waiting for a request on a WOLA
connection at the same time a separate task calls unregister
and starts to close that connection.  Under some circumstances
both tasks will issue the MVS wait macro on the ECB used to
manage the connection at the same time.  This results in an
ABEND code 301.
The CICS link server used by WOLA uses the unregister force
API when the BBOC transaction is invoked, for functions
"unregister" or "stop_srvr".

Problem conclusion

Code was added to prevent the ABEND301/ABENDS301 when the
BBOA1URG API is invoked.

APAR PI21332 is currently targeted for inclusion in Fix Packs
8.0.0.10 and 8.5.5.4 of WebSphere Application Server.
