WebSphere Application Server (WAS) Message Engine (ME) was started and all of sudden your application is unable to send the messages to the BUS.
In the SystemOut.log initially the error DSRA0080E is reported from the message data store component followed by J2CA0056I. Each of these messages is repeated several times. This sequence is then followed by message codes CWSIS1546I and CWSIS1538I, which indicate that the lock on the database has been lost and repeated attempts are being made to recover the lock. Finally the application server JVM is terminated by HA manager to avoid any possible data loss. Message HMGR0130I appears before it terminates the JVM. The application server is terminated in a orderly way.
In the SystemOut.log:
DSRA0080E: An exception was received by the Data Store Adapter. See original exception message: com.ibm.db2.jcc.b.SqlException: invalid operation: connection closed at com.ibm.db2.jcc.b.o.yb(o.java(Compiled Code))

These errors occurred due to network errors or connectivity issues with the database. These errors could have also occurred if there were any other problems with the database or if the database is closed. Fix these errors to resolve the problem and restart the application server.
In WebSphere Application server 7.0 and 8.0 we have introduced a custom property: sib.msgstore.jdbcFailoverOnDBConnectionLoss on a messaging engine. The default value in version 7.0 is set to true which means: The high availability manager stops the messaging engine and its hosting application server when the next core group service isAlive check takes place (the default value is 120 seconds). If a node agent is monitoring the server, and you have enabled automatic restart in the monitoring policy for the server, the server restarts. The messaging engine starts when an appropriate server is available. You can set this value to FALSE and it will not to terminate the JVM. In this case it behaves the same as version 6.0 default behavior as mentioned below.
In WAS V6.0 and V6.1 we do not have this custom parameter, In this case, the messaging engine continues to run and accept work, and periodically attempts to regain the connection to the data store. If work continues to be submitted to the messaging engine while the data store is unavailable, the results can be unpredictable, and the messaging engine can be in an inconsistent state when the data store connection is restored.
In WAS V8.5, when a database connectivity failure occurs the messaging engine instance is stopped gracefully and failed over to the standby instance. So the other applications running within the server continue to run.
