Am getting the below error intermittently.
ERROR Exception occured while fetching the available subscriptions from the database - Could not roll back Hibernate transaction; nested exception is org.hibernate.TransactionException: JDBC rollback failed

java.sql.SQLException: OALL8 is in an inconsistent state
Database: Oracle9i
JDBC Driver: 10.2.0.4.0
Developement environment: Mule 3.0, Spring 3.0 and Hibernate 3
"OALL8 is in an inconsistent state" is a generic exception that occurs in JDBC 10.1, 10.2, and 11.1. It indicates that an internal inconsistency has been detected in the JDBC connection but it does not provide information on what caused the inconsistency. The exception no longer occurs in JDBC 11.2. The error is usually caused by a bug in the JDBC code. These are very hard to analyze. The simplest solution is to upgrade the JDBC driver.
