PK79133: JCA ADAPTER STOPS POLLING WHEN HIGH AVAILABILITY IS ENABLED BECAUSE MESSAGING ENDPOINT IS NOT ACTIVATED

Fixes are available

APAR status

Closed as program error.

Error description

When using a JCA 1.5 adapter, if the High Availability feature
is activated, the messaging endpoint of the adapter is not
activated.  This results in the polling feature of the JCA
adapter to stop, which causes the flow of data to/from the data
source to stop.
.
   The message endpoint is an endpoint used to receive a polling
message from the data source.
.
   The problem that was reported was using the IBM J2CA Adapter.
.

show the polling being enabled with the WBI adapter.

****************************************************************
Message endpoints defined over the ActivationSpecs of a
resource adapter configured for inbound High
Availabilty fail to activate when the resource adapter is
activated within a cluster.  The problem occurs because the
WebSphere Application Server connection manager fails to
activate the endpoints when the High Availability manager
activates the member adapter within the cluster.  The
problem manifests within WebSphere Adapters as a symptom where
a adapter stops polling for events -- for example, the
WebSphere Adapter for flat files stops polling for file
system events, like the creation of a file.

Problem conclusion

Apply APAR PK79133 to enable the connection manager to
activate the message endpoints of a resource adapter,
configured for high availability within a cluster, when the
High Availability manager activates the member adapter within
the High Availability Group.

To enable the fix behavior, define and set the following JVM
system property within the configuration of each server in the
cluster:

-Dcom.ibm.ejs.j2c.RAWrapper.changeMemberStateOnActivating=true

The fix for this APAR is currently targeted for inclusion in
fixpacks 6.0.2.25, 6.1.0.25, and 7.0.0.5.  Please refer to
