APAR status

Closed as program error.

Error description

The z/OS ProxyMBeanSupport code unregisters a Java Management
Extension (JMX) Management Bean (MBean) when the count
of servant regions being managed for the MBean becomes zero.
This is incorrect for MBeans which are registered by adjunct
region(s).

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server V6.1.0 for z/OS                      *
****************************************************************
* PROBLEM DESCRIPTION: Java Management Extension Management    *
*                      Beans unregisterd from adjunct region   *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
Java Management Extension (JMX) Management Beans (MBeans)
registered in the z/OS adjunct region, for example, Service
Integration Bus (SIB) MBeans, may be incorrectly unregistered
by the Control region proxy
com.ibm.ws390.management.ProxyMBeanSupport
because the count of Servant regions managing the MBean is
zero.  This may result in MBeans being unavailable.  Expanding
Application Servers --> <server name> --> Messaging engines in
the administrative console may display status as "unavailable."

Problem conclusion

The code has been modified such that, the count of MBeans being
managed in the adjunct region is considered before unregistering
the MBean.

APAR PK88027 is currently targeted for inclusion in Service
Level (Fix Pack) 6.1.0.27 of WebSphere Application Server V6.1
for z/OS.
