Suspend transaction qualifier

When the invocation is synchronous, this qualifier determines whether client will propagate the transaction to the target component.

The suspend transaction qualifier applies when the implementation is running in a global transaction and makes a synchronous invocation. It determines if that global transaction is to be propagated to the target component. A transaction cannot propagate to the target if the implementation is running in a local transaction or if the invocation is done asynchronously. Under those conditions, this qualifier is ignored.

If the implementation is running in a global transaction, that transaction is propagated on all synchronous invocations to the target components by default. If those target components can join the global transaction and you do not want this to happen, add this qualifier and set its value to "true".

Location: The suspend transaction qualifier is set on a reference.

Settings: The suspend transaction qualifier can have these settings:

• False (default) - Synchronous invocations run completely within any client global transaction.
• True - Synchronous invocations occur outside any client global transaction. The target service's transactional environment is not affected by this qualifier.

Application: When suspend transaction is set to "true", the target component's effective transaction environment is either a new global transaction or a local transaction. The suspend transaction reference qualifier is ignored for asynchronous interactions.
