Delay before uncomplete transaction removed

[john smile]

When a workstation losts connection to server,
it can leave an uncomplete transaction. Then
SQL Server removes the transaction.
Could anyone guide me how to set the delay
before SQL Server do it ?

Thanks in advance

I'm not sure I understand your question - as far as I know, MSSQL will
rollback the transaction immediately, but why would you want to delay
the rollback? Perhaps if you can explain what problem you are trying
to solve, someone will be able to make a suggestion.

Simon, thanks for the response.

It means : I want to know for sure how many seconds
is it from connection failure to the beginning
of rollback.

No, I do not want to delay it.
If possible, I want to make the delay short,
as short as possible by adjusting any parameters
(like in Novell Netware : "number of watchdog -
packets", "delay between watchdog packets").
Perhaps if you can explain what problem you are trying

to solve, someone will be able to make a suggestion. >>

Currently, I have no problem. It is only a question.
I also want to ask :
If I found that SQL Server took long to rollback
an uncommitted small transaction caused by a network
failure, what should I do ?

Design your transactions better.

Seriously, this is one of the issues we've looked at as we're moving to
clustering. Clustering basically involves shutting down and restarting SQL
Server, so any long transactions affect your failover time. And if for
example you had transactions that take 15 minutes to rollforward or back,
your failover will take at least that long to occur. Which sorta negates
the usefullness in most cases.

Generally small transactions won't take long at all to rollback. Even lots
of them.
