Oracle Tuxedo / Tuxedo / 8.1,9.1

If a Tuxedo server program crashes after starting a transaction, the transaction does not get aborted for
"timeout" value specified in the call to tpbegin(). This condition happens only when the application program
is configured with RESTART=Y. When RESTART=N, the transaction aborts in about 2 - 3  minutes consistently irrespective
of the "timeout" value specified in tpbegin().

The following are the conditions observed, when the server application that intiated the transaction crashed -or- was

1) Restart=Y, timeout=0: Transaction does not timeout at all.
2) Restart=Y, timeout=600: Transaction times out in 600 seconds
3) Restart=N, timeout=0: Transaction times out in approx 2 minutes.
4) Restart=N, timeout=600: Transaction times out in approx 2 minutes.

Customer Requirement :
They specify a transaction timeout of 10 minutes. When RESTART=Y, if the server crashes, they wait for 10 minutes to
restart the transaction. When RESTART=N, the transation aborts in about 2 minutes. 

Why would RESTART=Y make a difference in a transaction timeout?

They want this to be fixed so that when a server crash, the transaction aborts in a consistently smaller timeframe so
that it can be restarted ASAP. This irrespective of whether RESTART=Y -or- N.
