Implicit transactions are handled automatically by Integration Server. For a flow to be managed implicitly, it can contain one of the following:
One local transaction, interacting with one resource
One or more XAResource transactions; each transaction can interact with one or more resources
One or more XAResource transactions and one local transaction
If a flow contains multiple local transactions, the adapter user must explicitly control the transactional units of work, as described in
Explicit Transaction Usage Cases.
