PK93000: JCA ADAPTERS THAT ARE STARTED DURING SERVER STARTUP ON WEBSPHERE APPLICATION SERVER Z/OS MAY NOT HAVE THEIR END POINTS ACTIVATED

Fixes are available

APAR status

Closed as program error.

Error description

- Customer Environment is WebSphere App Server z/OS 6.1.0.25,
WebServices Feature Pack 6.1.0.25, WPS 6.2.0.1, WebSphere
 Adapter for SAP 6.2.0.1.
- Customer application includes the .rar file for the SAP
 Adapter, so the SAP Adapter is not installed into the WebSphere
 Application Server.
- SAP Adapter Endpoints should be started during Server Startup
 by the 'container' code of the App. Server.  During the start
 of the server, the J2C code starts the endPoint Listeners.
 HAManager is not fully initialized at the time the J2C code
 is activating the endPoint, which causes the endPoint to NOT
 be activated.

Local fix

You can set the custom property: 'enableHASupport' to false
for the SAP Adapter packaged with your application.
To do this, you go to the Admin Console:
>> Enterprise Applications >> Application that has the SAP rar
>> Manage Modules >> 'yourname SAPAdapter.rar >> 'Appname.IBM
WebSphereAdapter for SAP Software with transaction support  >>
custom properties
..
You should see an 'name / value' pair for enableHASupport / true
in the list of custom properties.
You can change this value to 'false', then restart the server.
..
NOTE that the above was changed when the server was a
Stand-Alone server, NOT in any cluster.
If the WebSphere App Server is part of a cluster, setting the
enableHASupport to false may NOT give the desired results.

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server V6.1.                                *
****************************************************************
* PROBLEM DESCRIPTION: Resource Adapter endpoints are not      *
*                      activated on z/OS when the custom       *
*                      property enableHASupport=true           *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The HA member state comparison to ACTIVATING always returns
false in z/OS because we do a reference comparison (==) and not
an object comparison (.equals). In z/OS this does not work as
the HA manager runs in the control region while the comparison
happens in the servant region where the application server
runs. The HA member state is serialized and sent from the
control process to the servant process and a reference
comparison will always return false. This results in the code
always considering the HA member as inactive and not activating
the endpoint.

Problem conclusion

The comparison of HA member state has been changed to an
object comparison. This results in the objects being compared
via the .equals() method.

APAR PK93000 is currently targeted for inclusion in
Service Level (Fix Pack) 6.1.0.28 of WebSphere
Application Server V6.1.
