sql server slow running.. Urgently..!

  • Hi

    Last 3 on wads my report server transaction logs is is 90%, today when i saw, it was full,

    i moved to another disk, i have enough space in transaction log,

    But my report server is running very slow,

    I check it locking, blocking, fragmentation, & i update statistics & performance monitor

    --

    Is there any else to check to check.

    & suggest me to things i need to do it furthese

    Please help me...

  • Not sure if I fully understand, but some ideas...

    I understand that you have full transaction logs. Are you performing transaction log backups?

    Apart from SQL, are there any other processes running on your server?

    Has there been a recent change in the application - eg more users hitting the system?

    Can you spot any problem queries - using for example a lot of CPU....

  • The trasanction log should not* affect the performance of the server.

    Take regular t-log backups to manage you t-log and provide PIT restores.

    for the performance issue you need to look at the worst performing queries via a server side trace and see what is happening behined the scenes. There may be a need for indexing or query tuning.

    Start by analysing the execution plans of the worst queries, post them here if you need any help interpreting them.

    There are a couple of scenarios where the transaction log could affect performance. If the log is continuously extending because it wasn't pre-allocated to a proper size you could see performance problems. Additionally, if your log is on a less than optimal storage array such as RAID 5 or if it is on a device that is shared by other database files it could cause problems.

    "Beliefs" get in the way of learning.

    Thats why i said should and not wont, there are off course circumstances where it can. But don't think that is what the OP is facing..
