database server suddenly running slow

Hi!
One of my database server suddenly running slow.When I clicked on the tree view of any instances on this server, its taking time to show the structure.
The network is fine I guess as another db server in the same network is working fine.More over it has more dbs than the problematic server.Though all the dbs on this server are working fine yet something is wrong with my db server.I cant see any err logged in event viewer or sql error log,but I am sure there is some problem.Till yesterday it was fine.Now it is too slow.Pls suggest what to do.The system has enough free memory.No dbs were added in past 1 week.

When I connect to the server by QA and click on the drop down box to view the dbs on the server, the QA gotta hanged.The same is the case when I use EM to view the db list or any other tree view.

What is the level of service packs installed on server for SQL?
Deepak Kumar –An eye for an eye and everyone shall be blind

i think u need to edit and save the sql server registration properties again and check the client network utility.

I set up the performance monitor for the above counters but it failed to capture.When I saw the event viewer I got the following error .
The Collect Procedure for the "Spooler" service in DLL "C:WINDOWSsystem32winspool.drv" generated an exception or returned an invalid status. Performance data returned by counter DLL will be not be returned in Perf Data Block. The exception or status code returned is the first DWORD in the attached data. What to do now?

I have sp3 installed.I dont think its a service pack issue because till yesterday everything was fine.

Client network utility on this server has the TCP/IP and named pipes enabled.Nothing here is changed .

I dont have much idea but i think spooler is printing service

check this microsoft link too.

Now the performance counter logs is working fine ,lets see after 20 min what the output it gives.

Even when I right click on the properties to see the properties window ..the time comsuming is more than 15 min

This could be a problem because of mismatch of few .DLL files on the client tools, uninstall the client tools and reinstall to take new settings with good performance. As a test you can try to access the server from other client’s machine. Satya SKJ

You see this mostly when the server runs out of diskspace. If your databases have the Full recovery model, without the appropriate backup strategy, your log files may be getting into GB terrirory.

you can have a look on system events and SQL error logs if there is any clue hidden there. (Because, After an action there is reaction.. Nothing happens by its own) Deepak Kumar –An eye for an eye and everyone shall be blind

Here is the details of performance logs.What I observed is that the processor time is more approx 99% which is more than usual.Now what to do.

I m sorry for the trouble that will be caused by above post.I have submitted the log file details completly.So moderator pls delete the above if it seems to be unnecessary

Some thing is there which is taking the maximum processor time.
Can I determine which db (or objects) is taking maximum time by PM.

Did you overlook my previous post about available diskspace?

Check Processes running on server from TaskManager, there may be any new/old Exe other then SQL running on it to raise CPU utilization all in sudden. Run below trace to find out, which database is working most.. SQLServer<img src=’/community/emoticons/emotion-2.gif’ alt=’

‘ />atabases(db_name)Transactions/sec Another, check master..sysprocesses table for CPU and other running process on SQL Server Deepak Kumar –An eye for an eye and everyone shall be blind

I checked performance counter’s data.. its avg is like: – Disk queue length 0.281985768
Disk Read 17.40145323
Disk Writes 3.272217778
Processor 99.65077937
Buffer cache hit ratio 99.73449125
Processor queue length5.007194245
there is almost normal activity on disk.. needless to say its not only SQL which is using all CPU. findout what all is running on server. Deepak Kumar –An eye for an eye and everyone shall be blind

WIth regard to this error refer to this KBAhttp://support.microsoft.com/Default.aspx?kbid=839397 to get the fix if the OS falls under as per specifications.

quote:Originally posted by aaronsandy I set up the performance monitor for the above counters but it failed to capture.When I saw the event viewer I got the following error .
The Collect Procedure for the "Spooler" service in DLL "C:WINDOWSsystem32winspool.drv" generated an exception or returned an invalid status. Performance data returned by counter DLL will be not be returned in Perf Data Block. The exception or status code returned is the first DWORD in the attached data. What to do now?
