  • RE: EFFECT OF TRUNCATE TABLE ON TRANSACTION ROLLBACK

    Bill Jackewicz (2/11/2010)


    It did take 20-25% longer (~10hours) to rollback than the elapsed time prior to killing the query (~8 hours).

    That's normal.

  • RE: Rebuild log in SQL Server 2005 database

    First question: Why do you need to rebuild the transaction log? That's not something to do lightly.

    Take a look at this: http://sqlinthewild.co.za/index.php/2009/06/09/deleting-the-transaction-log/

  • RE: Process ID 'x' was killed by hostname XYZ, host process ID 'xxx'.

    The fact that DTA doesn't find anything, doesn't mean that there isn't opportunity for improvement. DTA is questionable at best.

    Searchable ARGument. It means a predicate in the where clause that can be used for an index seek operation. As a very high level summary, that's...

  • RE: Process ID 'x' was killed by hostname XYZ, host process ID 'xxx'.

    Someone (who's using a computer with the name given in hostname XYZ) is running the KILL command and killing processes.

    Find the person and tell them to stop.

    That's likely not the...

    That's a really vague question. There's nothing inherently wrong with nested loop joins and constant scans. Is it slow? Is there blocking? Are there timeouts?

    Enterprise edition only.
