  • RE: Should DBA's need to know the physical details of a SAN??

    My comment was directed at an optimally sized/configured SAN. I don't consider a SAN with 512 LUNs to be optimally configured for database throughput. DAS with that many...

  • RE: Identifying Resources Hogs (Users)

    Nice site name colin! 😀

    I note, however, that your links on the 2005 page end in .mht for URL as opposed to htm. I tried to hit the...

  • RE: UNION statement kills processor (but only as StoredProc)

    1) You state "started throwing this error" but don't specify an actual error.

    2) Sprocs will often run differently than hard-coded statements. With manual executions the query optimizer has explicit...

  • RE: Passing a Table to A Stored Procedure

    A bulk insert method will beat individual inserts in most if not all cases. Here you would avoid the network and execution hits in addition. Linchi Shea did...

  • RE: Hidden RBAR: Triangular Joins

    Hey, thanks for the flattery!! hehehe

    You are correct though - seems that a LOT of people out there have misconceptions about sets and ordering.

  • RE: Hidden RBAR: Triangular Joins

    Stealing my thunder Gila! I already posted on that yesterday at 8:54. 🙂

  • RE: Passing a Table to A Stored Procedure

    A trigger based system could work, as could an asynchronous mechanism other than replication as well.

  • RE: Should DBA's need to know the physical details of a SAN??

    Two points you are missing in the performance equation Colin. With a SAN it isn't just about the disk I/O capability. SANs usually come with large (sometimes many...

  • RE: Performance Effects of NOCOUNT

    The big thing to take into account with NOCOUNT (or read uncommitted isolation level) is the fairly recently (last 18 months or so I believe) discovered situation whereby you can...

  • RE: Hidden RBAR: Triangular Joins

    I 'believe' the optimizer can choose an allocation unit scan instead of a clustered index scan - which would allow unordered rows returned from your table with a clustered index....

  • RE: Performance Effects of NOCOUNT

    Try running the dbo/nondbo test again where there are objects with the same name owned by the non-dbo user. See if anything is different then.

  • RE: Hidden RBAR: Triangular Joins

    Be careful Ramesh - I don't believe that 'special' feature of sql server on the UPDATE statement is guaranteed to work in the future. It may also be dependent...

  • RE: Allocation Size

    Well, with 2 drives per RAID set you don't have RAID 1+0 - simply RAID 1. You need 4 drives min for RAID 10.

    Your setup is reasonable. I...

  • RE: Hidden RBAR: Triangular Joins

    I must say that I am very happy that people can do things like the triangular join - and sad that Jeff may make less people do it. Lost...

  • RE: Allocation Size

    There is a huge amount of variables to the configuration of storage, including but not limited to:

    RAID type

    number of spindles per RAID set

    HBA cache and cache ratio as well as...
