forgiving a query by not killing it.

  • Hi guys,

    if there is a large database.and someone fires a query(it can be t-sql or rpc).

    its taking a hell lot of time.i dont wanna kill this process instead can we do something to speed up this process like playing with tempdb or log files.

  • Not while it's running.

  • I would agree with Gail. Once it starts, there's nothing you can do. Before it starts, there are some config possibilities (MAXDOP, Query limits), Resource Governer (SS2K8) that can help mitigate issues.

    You also can tune the query, indexing, data file placement, to make specific types of queries run faster.

  • If the query is blocked, you could kill the blocking connection, but something still has to die.

    Yeah, I was going to say, killl all the other connections so the bad one has a clear path and all the resources.
