> Defect Tracker #24910: txnAutoWrap = OFF in 5.5 disables the use of local transactions.   This was primarily done to support customers who 1. weren't paying for the transactional product
> 2. weren't using an XA connection for an update
> The concern of 1 goes away in 5.6 as all customers will have a transactional product.  The secondary concern requires either a connection property that either ignores autocommit or the generic support of 1 phase commit on connectors supporting update and local transactions.  The latter solution would allow non-XA aware connectors to seem XA aware as long as all updates went to a single source.  Arjuna would also need to be configured to support the one phase commit optimization.
