Error description

Starting and Stopping an application on a z/OS may result in an
inconsistent application state between the Servants & Adjunct
regions.
The application state can only be made consistent after a server
restart.

Set Custom Properties
"com.ibm.ws390.management.proxy.ApplicationMgrMBeanProxy.zos.pre
FilterCheck" to "true".

Do this at the AppServer Level for each Control, Adjunct and
Servant region Java Virtual Machine definiton



For example, to update the Control Region JVM
#  From the AdminConsole.  Select the AppServer and under
   "Server Infrastructure" select "Process Definition"

#  Then select the "Control" and "Custom Properties "

#  Then "NEW", add the follwoing property name and value


com.ibm.ws390.management.proxy.ApplicationMgrMBeanProxy.zos.
preFilterCheck with a value of true



#   Save your change by selecting "Apply"



Application servers > server1 > Process Definition > Control >
Custom Properties > should now show the new property
com.ibm.ws390.management.proxy.ApplicationMgrMBeanProxy.zos.preF
ilterCheck

with a value of true

Repeat for Adjunct and Servant region JVMs

Save changes and synchronise Nodes if an ND configuration is
being used.

Restart the server to pick up the new property.

****************************************************************
* USERS AFFECTED:  All users of WebSphere Application Server   *
*                  V6.0.1                                      *
****************************************************************
* PROBLEM DESCRIPTION: The ApplicationMgr did not provide a    *
*                      facility for maintaining a consistent   *
*                      application stop state between          *
*                      regions on z/OS.                        *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
Runtime components can control whether applications should
start or stop by installing a DeployedApplicationFilter with
the ApplicationMgr. On z/OS, each region has it's own set of
runtime components and installed DeployedApplicationFilters.
When an application is stopped on all regions, it is possible
for some regions to agree to the application stop while others
don't. This results in an inconsistent application state
across the regions.

Problem conclusion

A flag has been introduced to enable a new behavior that will
attempt to maintain a consistent application state among the
regions on z/OS. A servant region will first be asked whether
the application can stop, before an application stop is issued
to all the regions.

APAR PK81647 is currently targeted for inclusion in Service
Level (Fix Pack) 6.0.2.39 of WebSphere Application Server
V6.0.1.
