Error description

Error Description?
CWSIP0065I message keeps on occurring in the logs after
selecting the SIBus link by deleting the foreign bus
connections on both ends. It never deletes the links.
.
SystemOut.log keeps on throwing the following messages:

SibMessage    I   [:] CWSIP0065I: The local Link <SIB_Link>
with UUID 971342B1428C64C109CDF3E7 has been marked for deletion.
.
The CWSIP0065I will appear each time the message engine is
restarted and it never delete the SIB_Link.
.
recreation scenation:
-------------
1. Create a WebSphere Application Server Network Deployment
edition cell with a single node and two application servers
"server1" and "server2" (_not_ configured as cluster).
2. Create two buses "bus1" and "bus2".
3. Add server1 as a member of bus1 and server2 as member of
bus2. Use a data store and let Application Server create a
default data source.
4. Create a foreign bus connection between bus1 and bus2. When
configuring the link on both ends, use "Configure a foreign bus
in the local cell" (so that there is no need configure the
provider endpoints explicitly).
5. Save the configuration, synchronize the node and start the
server.
6. Wait for the messaging engines to start.
7. In the administrative console, check that the SIBus link is
started and working correctly.
8. Delete the SIBus link by deleting the foreign bus
connections on both ends.
9. Save the configuration and synchronize the node. At this
point, the following messages should appear in the
SystemOut.log file of both servers:

SibMessage    I   [:] CWSID0019I: Configuration reload is
starting for messaging engine <ME1>.
.
SibMessage    I   [:] CWSIP0065I: The local Link bus1:bus2 with
UUID <UUID> has been marked for deletion.

SibMessage    I   [:] CWSID0020I: Configuration reload is
complete for messaging engine <ME1>
.
SibMessage    I   [<bus>] CWSIT0033I: The service integration
bus link TestLink
from messaging engine <ME_name1> in bus <bus name1>  to
messaging engine <ME2>  in bus <bus name2> stopped.
.
10. Restart the two application servers. The following messages
appear
in the SystemOut.log file of both servers:

00000029 SibMessage    I   [<bus>] CWSIP0212I: Messaging engine
<ME1> on bus bus1 is starting to reconcile the WCCM destination
and link configuration.

SibMessage    I   <bus1>] CWSIP0065I: The local Link bus1:bus2
with UUID <UUID> has been marked for deletion.

SibMessage    I   [<bus1> CWSIP0213I: Messaging engine <ME1> on
bus bus1 has finished reconciling the WCCM destination and link
configuration.

The CWSIP0065I will appear each time the message engine is
restarted.

Problem summary

****************************************************************
* USERS AFFECTED:  Users of the default messaging provider     *
*                  for                                         *
*                  IBM WebSphere Application Server            *
****************************************************************
* PROBLEM DESCRIPTION: In a WebSphere Application Server       *
*                      Service Integration Bus, when a SIB     *
*                      link is deleted, the state of the       *
*                      link changes to DELETE_PENDING state    *
*                      but never actually is deleted.          *
*                      However, the entry for the              *
*                      corresponding bus link would be         *
*                      deleted in the configuration file.      *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
When the SIB link is deleted, the state of the link changes to
DELETE_PENDING state and we see an entry in the SystemOut log
indicating this. The corresponding entry of the bus link
would be deleted in the configuration file successfully, but,
the link would still be in DELETE_PENDING state and never gets
deleted. You would see the following entry in the SystemOut
logs on every restart which indicates that the link is still
in DELETE_PENDING state -
CWSIP0063I: The local destination <bus_link_name> with UUID
<bus_link_UUID> has been marked for deletion.
The repeated entries of the above exception after every
restart would clearly indicate that the bus link is not yet
deleted/removed from the message store. A dump of message
store after the deletion of the Bus link indicates that the
message store still contains entries related to the Bus link.
However, the entry would be correctly flagged with
toBeDeleted=true.

Problem conclusion

The solution involves flushing the streams related to the bus
link. This will result in the successful completion of the
deletion process of the bus link, and would avoid CWSIP0063I
since the bus link is completely deleted.

The fix for this APAR is currently targeted for inclusion in
fix packs 6.1.0.45, 7.0.0.27, 8.0.0.6, 8.5.0.1. Please refer
