Hi all,
One of my production sqlserver is taking more memory usage
in win task manager ----> Process it is showing sqlservr.exe :1,337,400k
server is of 2gb RAM
when ever this issue comes we r restarting the server for time being its ok .
But every time restarting the production server is not the good criteria
all users are complaining the server is slow () it is taking too much time to insert data from front end application.
we are using
Microsoft SQL Server 2000 - 8.00.2039 (Intel X86) May 3 2005 23:18:38 Copyright (c) 1988-2003 Microsoft Corporation Personal Edition on Windows NT 5.2 (Build 3790: Service Pack 2, v.4354)
can pls send the some valuble solution to fix this issue (w/o restarting the server).
Thanks in advance

Set up a trace and identify any query that hurts performance

Hi,

in win task manager ----> Process it is showing sqlservr.exe :1,337,400k
server is of 2gb RAM

First check the memory using perfmon.msc

See the discussion

Personal Edition maximum support 2GB.So u need to upgrade ur sql edition.

With help of perfmon you can check following memory related counters:

SQLServer:Memory Manager\Memory Grants Pending

SQLServer:Memory Manager\Total Server Memory (KB)

Memory\Pages/sec

Also you can add few more counters and check memory as well as any other hardware bottlenack if any.

The numbers you posted sound normal to me for SQL Server. It sounds to me like you don't understand how SQL Server uses memory. Take a look through my blog post:

Troubleshooting the SQL Server Memory Leak (or Understanding SQL Server Memory Usage)

If you don't want SQL Server to use all of the available memory, then you need to configure the max server memory setting to control how much it can use. Slow inserts won't be associated with SQL Server using memory, in fact reducing memory to SQL can actually cause further problems with performance of inserts since you are going to force SQL Server to have to do more hard IO to disk which impacts write performance as a side effect.

What are the top 10 wait types for the SQL Server?

SELECT TOP 10 *

FROM sys.dm_os_wait_stats

WHERE wait_time_ms > 0 -- remove zero wait_time

AND wait_type NOT IN -- filter out additional irrelevant waits

( 'SLEEP_TASK', 'BROKER_TASK_STOP', 'BROKER_TO_FLUSH',

'SQLTRACE_BUFFER_FLUSH', 'CLR_AUTO_EVENT', 'CLR_MANUAL_EVENT',

'LAZYWRITER_SLEEP', 'SLEEP_SYSTEMTASK', 'SLEEP_BPOOL_FLUSH',

'BROKER_EVENTHANDLER', 'XE_DISPATCHER_WAIT', 'FT_IFTSHC_MUTEX',

'CHECKPOINT_QUEUE', 'FT_IFTS_SCHEDULER_IDLE_WAIT', 'BROKER_TRANSMITTER',

'FT_IFTSHC_MUTEX', 'KSOURCE_WAKEUP', 'LAZYWRITER_SLEEP', 'LOGMGR_QUEUE',

'ONDEMAND_TASK_QUEUE','REQUEST_FOR_DEADLOCK_SEARCH', 'XE_TIMER_EVENT'

)

ORDER BY wait_time_ms DESC
