Is setTransactionTimeout reliable?

[Sanujit Senapati]

I am trying to use the setTransactionTimeout() method in a BMT Stateless Session Bean on WebSphere 5. Is it reliable? in the sense that after a timeout, does the SystemException (or RollbackException) leave the server in a safe state.

Thanks,
Sanujit

The transaction timeout values are generally enforced by the container. When the timeout value is exceeded, an XA-type exception is generally thrown by the container.

I generally like to set a large timeout value (5 minutes or more). Sometimes, latencies in the database, network, O/S will cause some transactions to take longer than normal. So to accomodate for these "normal deviations", I don't want to transaction to timeout prematurely.
