JCA Binding execute of Reference operation 'merge' failed due to: DBWriteInteractionSpec Execute Failed Exception

Another problem I faced today while using the DbAdapter for merging rows from another web service (as per my previous blog) was that commits failed. This turned out to be because Global Transactions were enabled on the Data Source that was referenced to by the DbAdapter configuration (see below).

Global Transactions can be disabled on the data source by going to: Home -> Data Sources -> Data source name -> Transactions -> Un-tick: Supports Global Transactions and then Save the data source.

 Exception occured when binding was invoked.  
 Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'merge' failed due to: DBWriteInteractionSpec Execute Failed Exception.  
 merge failed. Descriptor name: [PPRPersistenceService.PriceData].  
 Caused by java.sql.SQLException: Cannot call Connection.commit in distributed transaction. Transaction Manager will commit the resource manager when the distributed transaction is committed..  
 Please see the logs for the full DBAdapter logging output prior to this exception. This exception is considered retriable, likely due to a communication failure. To classify it as non-retriable instead add property nonRetriableErrorCodes with value "0" to your deployment descriptor (i.e. weblogic-ra.xml). To auto retry a retriable fault set these composite.xml properties for this invoke: jca.retry.interval, jca.retry.count, and jca.retry.backoff. All properties are integers.

 The invoked JCA adapter raised a resource exception.  
 Please examine the above error message carefully to determine a resolution.
