--------------------------------------
Ritika,
The message you referenced...
<0|true|0.9.6-incubating> org.apache.openjpa.persistence.PersistenceException:
DSRA9250E: Operation setTransactionIsolation is not allowed during a global
transaction for Shareable Connections.
... is coming from WebSphere. WebSphere supports the concept of shareable
connections (per the JCA specification). Since these connections might be
shared between applications, WebSphere doesn't want to surprise the user of a
Shareable connection by allowing modification of properties that could affect
the operation of that connection. In this case, somebody (OpenJPA?) is
attempting to change the TransactionIsolation attribute of a Shareable
connection while a global transaction is active. WebSphere prevents this as a
safety net for our users. So, it looks like you need to understand why the
transaction isolation is attempted to be set while the transaction is active.
Either we need to hold off on changing the transaction isolation until the tran
completes, or maybe the setting is superfluous (ie. the isolation level is not
changing, but the invocation is happening regardless).
Hope this helps.
