A "javax.transaction.RollbackException" is thrown when BPEL PM is under heavy load.

Caused by: ORABPEL-11622
Could not create/access the TopLink Session.
This session is used to connect to the datastore. [Caused by: Transaction has been marked for rollback: Timed out]
See root exception for the specific exception. You may need to configure the connection settings in the deployment descriptor
(i.e. $J2EE_HOME/application-deployments/default/DbAdapter/oc4j-ra.xml) and restart the server. Caused by Exception [TOPLINK-23005]
(Oracle TopLink - 10g Release 3 ( (Build 061004)):
Exception Description: Error binding to externally managed transaction
Internal Exception: javax.transaction.RollbackException: Transaction has been marked for rollback

A step by step solution for this error is shown as under:
a. Goto SOA_HOME/bpel/domains//config

b. Open domain.xml and change syncMaxWaitTime to 1800.
(If the existing value is more than this don't make any changes here)

c. Goto SOA_HOME/j2ee/OC4J_SOA/application-deployments/orabpel/ejb_ob_engine

d. Open orion-ejb-jar.xml and change all the transaction-timeout values to 3600. (If the existing value is more than this don't make any changes here).

e. Goto SOA_HOME/j2ee/OC4J_SOA/config

f. Open transaction-manager.xml and change transaction-timeout value to 7200. (This value you could use as high as 60000, if needed).
