Whilst using SOA 184.108.40.206 you randomly receive error "ORA-03111: break received on communication channel" when using an Oracle Technology Adapter that interfaces with a database using the JDBC thin driver. The adapter could be configured to use any of: Database, AQ, Oracle Applications, or AQ-JMS.
A similar error will be seen in the logfile at $MIDDLEWARE_HOME/user_projects/domains/base_domain/servers/soa_server1/logs/<SOA Managed Server Name>-diagnostic.log (this example is from the use of an Oracle Applications Adapter):
Stored procedure invocation error.
Error while trying to prepare and execute the APPS.XOPS_ITEM.ITEM API.
An error occurred while preparing and executing the APPS.XOPS_TEM.ITEM API. Cause: java.sql.SQLException: ORA-03111: break received on communication channel
Check to ensure that the API is defined in the database and that the parameters match the signature of the API. This exception is considered retriable, likely due to a communication failure. Because the global transaction is rolling back the invoke must be retried in a new transaction, restarting from the place of the last transaction commit. To classify it as non-retriable instead add property nonRetriableErrorCodes with value "1013" to your deployment descriptor (i.e. weblogic-ra.xml).
