    Active. The log records are still needed by something, in this case the checkpoint.

    A VLF is only inactive when none of the log records in it are needed for...

  • RE: Version Store isolation levels confusion

    GilaMonster (10/10/2012)


    Triggers use the version store. So do online index creation and rebuild.

    Thanks Gail

    Is there a way that I can check how the contents of my version store arrived there,...

    Isolation Level can be handled by session level also, not only database level, if I am right.

    Is there any chance your application issue that?

    You can use snapshot isolation level...

    Reads from the physical disk are always read into the "Buffer Pool". It's the reads from that "Buffer Pool" that SQL Profiler counts.

    Nothing to do with the buffer pool. That's the workspace memory grant for the query to do operations that themselves require memory. Hashes, sorts, exchanges, that sort...

    What I'm trying to understand is which of your resources are taxed the most when dealing with bad parameter sniffing

  • RE: Disk to memory and back again
