Error description

When the z/OS Connect instance is stopped/started we get the
abend in the BBOATRUE running in CICS at the time of the
WOLA
rebind. z/OS Connect 2.0.7, WLP 16.0.0.3, Angel version 5

IEA794I SVC DUMP HAS CAPTURED:  260
DUMPID=010 REQUESTED BY JOB (XXXXXXX)
DUMP TITLE=COMPON=WEBSPHERE Z/OS,
COMPID=5655I3500,
ID=server_wola_client_rebind.wolaClientRebind()

Local fix

A work around is to stop the CICS region (or stop the WOLA
connection) before stopping/restarting z/OS Connect. Then
restart CICS (or WOLA connection).

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server Liberty for z/OS                     *
****************************************************************
* PROBLEM DESCRIPTION: An SVCDUMP occurs when a WOLA client    *
*                      such as CICS attempts to re-connect to  *
*                      a Liberty server that has been          *
*                      restarted.                              *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
A client such as CICS might maintain a connection to a Liberty
server using WOLA for a long period of time.  If that Liberty
server is recycled, the client can automatically re-connect to
the new instance of that server when it is restarted.  The WOLA
CICS link server that ships with Liberty is one example of a
client that does this.  In some cases, if the Liberty server
cannot process new connection requests quickly after it is
restarted, the client may produce an SVCDUMP.  The client should
retry the connection attempt rather than take an SVCDUMP.

Problem conclusion

Code was added to the WOLA CICS link server to be more tolerant
of timeouts that can occur when establishing connections between
a WOLA client and Liberty server.

The fix for this APAR is currently targeted for inclusion in fix
pack 17.0.0.2.  Please refer to the Recommended Updates page for
