PM29846: VMM ROLLS BACK GLOBAL TRANSACTION IF VMM OPERATION FAILS.

Fixes are available

APAR status

Closed as program error.

Error description

Virtual member manager (VMM) joins a transaction if one is in
progress, otherwise it creates a new one. If an exception
occurs at any point during the call, the transaction fails,
and may be rolled back. VMM cannot determine whether the
transaction failed or succeeded based on the exception that
was thrown. VMM should provide functionality to suspend active
Global Transaction, and create a new one internally before
calling VMM API.So, even If any call fails, the Global
transaction of the caller will remain intact.

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server V6.1 and V7.0                        *
****************************************************************
* PROBLEM DESCRIPTION: VMM rolls back the active global        *
*                      transaction when any VMM operation      *
*                      fails intermediately.                   *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
VMM uses and continues active global transactions. So when VMM
internally fails in an operation, it sets Global transaction to
rollback. VMM cannot determine if the transaction succeeded or
failed based on the exception received.

Problem conclusion

A new custom property needs to be added to the security.xml
file under WIMUserRegistry.
<properties xmi:id="Property_1294045326812"
name="com.ibm.ws.wim.registry.useGlobalTransaction"
value="false" />

The previous line should be put inside the userRegistries tag
for WIMUserRegistry generally ID is WIMUserRegistry_1.

When the variable is set to false then VMM creates a NEW
transaction internally, So no global transaction is affected.

The fix for this APAR is currently targeted for inclusion in
fix packs 6.1.0.39, 7.0.0.19.  Please refer to the
