Hi,
I am currently using a single SQL Server Express Instance on a Core 2 Duo
box.
I know that the Express version is limited to use 1 CPU/Core.
I now want to setup a second SQL Server Express instance for unrelated
purposes.
Is it possible to give one instance Core 0 prio, and the Second the Core 1
prio, or do they ALWAYS (MUST/ONLY) use Core 0?
Also, if I don't set it specifically will Windows manage it properly?
I guess my main question in detail is:
Is the Express version build in such a way that it will always use the first
core/cpu regardless how many there are? For example, if I have 3 instances
running, would they all fight for cycles on the first core/cpu?
If not, do I have to do/set something to make it work properly?
Thanks for any Info. on this!
Regards,
FrankExpress will only create one scheduler. A scheduler is by default not bound to a particular core, it
can "float" between the cores. However, there is no guarantee that your two express instances will
always be on different cores.
However, you can use sp_configure and the "affinity mask" option to specify that instance it is tied
to core 0 and instance 2 is tied to core 1. This way you've configured the two instances to use
different cores.

To add on to Tibor's response, the OS can schedule work on any available
core when the SQL Server affinity mask is not set. You do not need to do
anything special to make this happen.

CPU, Physical IO, & Memory Usage
I was wondering about what the values in Management->Current
Activity->Process Info represent. Are the values for CPU, Physical IO, &
Memory Usage cumulative or do they represent a max or a current value?
The reason I'm wondering is that I saw a large value for Memory Usage by a
process recently. The value was in the millions. Most other processes had
values < 100 and some went up to 4000 or so.
Should I be worrying about such a large value for any of these parameters?
Thanks
MG
They are cumulative values from the time the user logged on. For the most
part they are pretty useless.

CPU utilization not even
Hi
I have windows 2000 advanced server and sql server 2000 EE. It is used for
datawarehouse . A report, which used to finish in 20 minutes now it is
taking 4 hours to finish. It is same query same indexes same database. I
look at the perf counters one cpu(4) is at 70% (average)utilization others
are at 3% (average). I also checked the interupts are 560/sec, I guess it
is something abnormal, can someone help me out
Thanks,
Subbu.
Hi
In the server settings, check that Maximum Query Plan threshold is at least
5. Looks like your query is only using 1 processor. Also check the SQL
Server is configured to use all processors.
Both are on the Processor tab on the Properties page for the Server.

CPU Utilization
Hi All,
I want to keep track of the CPU utilization & number of users connected for each database on our production box. I chose to get the data from sysprocesses table from master database.
But I realised that for some reason the master..sysprocesses.CPU column stays static or just keeps on adding to existing values.
Is there any ways thru which I can clear this data ( cpu column in sysprocesses table) after I have captured it in a table ?
Any help is appreciated.
Thanks.You may be better off using perfmon with those two counters. yOu can put the output to a .csv, for later import into databases. This will not give you CPU usage per connection, however, so it is somewhat useless if you want to do chargebacks of some sort.

CPU Utiliization reaches 100% when using ExcelPivot Table to browse AS 2005 Cube
CPU Utiliization reaches 100% when using ExcelPivot Table to browse AS 2005 Cube. Only one user is using the cube. Its a single CPU with SQL Server running on the same box. Is there any configuration parameters I should be changing ?
Thanks
SelvaHi Selva,
This is nothing to do with your question. But I was wondering if you have been able to drill down hierarchy levels from your cube in your excel pivot table? Because I can't. Have you tried that. Also, I will say, that I had similar issue browsing a cube from the pivot table, but I had to filter my pivot table, so I wouldn't be pulling so many rows (3 million). Filter it down and see how it responds.
CPU Using - Audit Logout
I have a VP app. that uses some queries from SQL Server 2000.
I'm noticing in SQL Profiler that the event "Audit Logout" is using alot of
cpu at times.
How can I decrease these CPU times ?Keep the connection open.

spikes the cpu. Can you tell if the times when it happens if any of the

I'm noticing in SQL Profiler that the event "Audit Logout" is using alot of
cpu at times.
How can I decrease these CPU times ?Keep the connection open.

CPU Use Rising
Hello Group,
what is a good starting point setting a trace to troubleshoot CPU usage? My
network admin asked me to look at one of the servers: it seems after our
weekly restarts, the CPU usage keeps rising. What can I begin to look at to
determine what is causing this?Rich,
Start with Task Manager to determine what app is causing the issue. If SQL
Server, then drill down using System Monitor and Profiler.

CPU Usage(%), Logical IO Performed (%) Usage for Adhoc Queries is 90%
Hello, When I am seeing SQL Server 2005 Management studio Server Dashboard> I am seeing my(USERS) databases and msdb database usage is very small % of in CPU Usage(%), Logical IO Performed (%) Usage pie chart.
90% of Total cpu usage is showing for Adhoc Queries. what excatly this means in Dashboard? if application uses more than it would have shown in Database level or not?
sicerely this dashboard is good, if any one is watching daily, please advice their experiences here.
Thanks in advance. Hail SQL Server!
This means that of all the CPU and I/O performed 90% is coming from Adhoc Queries, it does not mean 90% CPU usage.

CPU Usage vs Catalog Population
I have an SQL account that uses FTS on SQL 2000.
I originally used Incremental Population to index the work done during the
day.
However, the indexing process was carrying over into the next work day.
Therefore, last week I changed the method to Change Tracking with Update
Index in Background (with John Kane's urging) to try to alleviate the loss
of performance being experienced during the day by the system's users.
It is my understanding that CT w/UIB would only perform indexing when the
CPU is idle and resources are available. By switching to this method, I
thought the overall performance would improve.
This morning I checked the SQL Server, CPU usage is averaging 60% and the
catalog status reports Population in Progress.
Consequently, all users are unable to perform logins, searches, ... because
of timeouts against the database.
I am remote to the application and finally got the menu up to issue the
command to stop population.
Q1:
I thought the Change Tracking with Update Index in Background option is to
prevent high CPU utilization.
Should I be seeing such high utilization with this option selected to the
point that other applications are timing out when trying to make a
connection to the database? Enterprise manager also times out when trying to
connect.
Q2:
The stop command has finally executed and the catalog status now reports
idle.
It has been over an hour and the CPU usage is still very high (50 - 60%).
Is this continued usage the result of the indexing process?
Is there residual processing that could go on for hours after the status
reports idle?
Q3:
Related to Q1, since the population status reports idle but I still see high
CPU utilization, how do I isolate what in particular is keeping the usage so
high? How to prove it is mssearch and not something else going on with the
database?
I see the sqlserver and mssearch processes listed in task mgr with high cpu
& memory usage.
Update index in background does not necessarily index when the CPU is idle
or resources are available. Rather it polls a table every second and indexed
rows which are marked to be re-indexed.
You might want to try a scheduled Update Index at intervals that work for
your requirements. For instance update the index every 1/2 hour.
If your table you are indexing is heavily updated you may run into these
problems with relatively high CPU utilization, you will also run into these
problems if your content is in German or Far East languages.
High CPU utilization just means your processor is busy, it isn't by itself a
bad thing. When it starts to cause execessive paging or create queueing is
when it can degrade overall system performance.
To isolate particular processes using high cpu you can use Performance
Monitor or simply sort the processes you find in Task Manager by CPU. You
can also run sp_who2 to get an idea of cumulative CPU and disk IO.

CPU Usage pegged at 100%
Last night we had reports that our website was not responding. After some
investigation we found that the issue was SQL Server had all of the CPU's
pegged at 100% on a server that usually runs no higher than 10%. Our site
was not exceptionally busy, nor have we installed anything new that accesses
the database recently. In the sQL Server Error Log I see alot of "buffer
latch errors", but they appear to have occurred after CPU usage had already
hit 100%.
No one here is really a SQL Server troubleshooting or tuning expert. What
should we do to try to determine the cause?
Thank youEvan,
This can be difficult to track down because you really do not have any idea
what was occuring at the time. You might consider creating an automated
proactive solution to tracking these kinds of issues by using Profiler,
jobs, alerts (performance condition alerts included), SysMon, MOM 2005
and/or a related third-party product.

CPU usage on SQL server
Hi,
I have a quad processor clustered database server that is experiencing
significant performance problems. There are multiple user databases on ther
server, and the issues manifest themselves in different ways. We have had
users unable to save to a database to complete slow down of the whole server
.
The issues seem to be more prevalent in the morning, but we have had them
throughout the day as well. In monitoring the CPU usage we noticed that mos
t
of the activity is going through only 1 of the CPU's. CPU 0 can peak at 100
%
utilisation, and the other 3 have little or no activity at all. There has
been no changes to any settings and the SQL Server install is pretty
standard. Does anyone have any ideas?Meg wrote:

Have you assigned SQL Server all CPUs? Are you using MAXDOP 1 option in
your queries or have you set the "max degree of parallelism" option on
the server? I would think SQL Server would use all CPUs even if MAXDOP 1
were used when running multiple queries. It's probably some bad query
that is running on a single CPU that is causing the CPU spike. Many
query operations run on a single CPU. And blocking is probably the
problem, not the CPU per se. Although the high CPU is probably causing
extended locking and blocking problems.
You need to profile your database and see how your queries are
performing and figure out which ones are running for long periods and
locking resources required by other SPIDs.
