I ran ALTER SERVER CONFIGURATION SET PROCESS AFFINITY CPU = 2,3 that means the SQL server 2012 is using the 2nd and 3rd CPU's respectively..
Now, when I run sp_configure 'affinity mask' I get the config_value as 12, so how it is getting calculated?
is there a code for each CPU?? wanted to know about this.
I have a dual 64 bit quad core server with 16 GB of memory. We are going to run an application server and SQL Server 2005 SP2 CU4 64 bit on this hardware, but we only want to purchase a single CPU license for SQL Server. The obvious choice is to use the affinity settings to prevent SQL Server from using one of the CPUs.
Initially, the development team simply went into SSMS and unchecked affinity mask and affinity io mask for the first four processors. This appeared to work fine in their testing. A problem arose when we started monitoring the maintenance plan and saw that the database integrity check was failing. The root problem was this invalid state that the affinity masks were in.
I have seen a lot of documentation stating the SQL Server will ignore an invalid mask setting, but in our testing, it appears that SQL Server respects the setting. For example, when we set CPU 7 to be available for processing and IO, Performance Monitor showed that only CPU 7 was used during a load test.
So from our preliminary testing, it looks like SQL Server will use a single CPU for both processing and IO if you tell it to. Is there some other reason why these affinity settings need to be mutually exclusive? Is there a test I can run that can illustrate why?
I'm experiencing some problem with the affinity mask and affinity I/O mask configuration.
We are running SQL Server Enterprise Edition 2005 64bit on Windows 2003 Server 64bit with 4 dual core CPU. The actuelly configuration is:
Affinity Mask Affinity I/O Mask
CPU0 0 0
CPU1 0 0
CPU2 1 1
CPU3 1 1
CPU4 1 1
CPU5 1 1
CPU6 1 1
CPU7 1 1
We did it so, because we are running LiteSpeed Tool for the backup. LiteSpeed is configured to use CPU0 and CPU1.
Now, we know that the settings are wrong. If Affinity mask is 1 affinity I/O mask should be 0 and vice-versa.
My question is: how many CPU should I enable for affinity mask and how many for affinity I/O mask. Which are the correct criterias.
Thx in advence.

We are having a problem with one of our SQL servers, and in comparing it to the backup server which is working fine, I noticed some differences. I attempted to correct the differences, but no luck.
The dell server has 4 dual-core processors and at one point hyper-threading was enabled. One of our DBAs recommended that it be turned off. We didn't have any major problems until recently and it seems that getting this setting right is the lynchpin. Any suggestions?

Hi All
Can u pls tell me How to Get the SQL Affinity Mask value in Sql 2005.
and what is the table/views name that store this info.
for SQL 2000 , we were using following query:
SQLStatement.printf("select c.value from master..sysconfigures c, master..spt_values v,"
"master..syscurconfigs r where v.type = 'C' and v.number = c.config and v.number >= 0 "
"and v.number = r.config and v.name ='affinity mask'");
lErrCode=SQLExecDirect(hStmt,(SQLCHAR*)pszSQLStatement,strlen(pszSQLStatement));
lSQLBindCol(nAffMask);
But With SQL 2005 , we are getting ZERO(0) ROWS SELECTED.
I have a table into which users can enter a To and From range, and an application returns all the values in between. Naturally the users can enter to and from values that don't exist, as all they need to do is satisfy a "between" expression. eg they can enter '1100' to '1399' and even though neither value actually exists in the data, the query will return all the values that fall into the desired range.
However the application now demands a bit more of a sophisticated approach. The target data may have the form 'nn-nnnn-nn' where n is '0' to '9', and the user wants to select all the values (in pseudo-code) which satisfy a pattern like '%-7040-%' and '%-7400-%'
A simple LIKE expression with a mask containing a RegEx won't work - ie LIKE '%-7[0-4][0-4]0-%' doesn't work because (eg) '00-7150-00' won't satisfy the mask because of the 5 falling outside [0-4], although it is within the range I want.
I have come up with a solution to this problem by using MIN and MAX aggregate functions on LIKE [From] and LIKE [To] respectively and this works fine. eg
"SELECT A.<something> from <target_table1> A, <table_with_ranges> B WHERE A.<something> BETWEEN (SELECT MIN(X.<something>) FROM <target_table1> X WHERE X.<something> LIKE B.[From]) AND (SELECT MAX(X.<something>) FROM <target_table1> X WHERE X.<something> LIKE B.[To])"
It's actually quite a bit more complicated than that - I have simplified the SQL a bit, but that is the basic algorithm.
The problem is that for the BETWEEN expression to work, both the MAX and MIN functions have to return a value that is not NULL- ie there has to be a value in the target table which satisfies the mask. In the application, this is not always going to be the case - Users will want to create large ranges to allow for future growth so every time they enter new data into target_table1 the don't then have to go out and redfine the [From] and [To] ranges to satisfy the new data. What I really need is an SQL expression along the lines of "SELECT .... FROM ... WHERE A BETWEEN <pattern1> AND <pattern2>" where <pattern1> and <pattern2> contain wildcards.
Anyone got any suggestions??? By the way, using SUBSTRING or other string functions is NOT an option for a variety of reasons.
I have a stored procedure in which we are deriving some flags. So, we used series of CASE statements.
For examples
CASE
WHEN LEFT(CommissionerCode, 3) IN ('ABC','DEF',...) THEN 1
WHEN PracticeCode IN (.......) THEN 1
WHEN (CommissionerCode IN (.....) OR PracticeCode NOT IN (.....) OR .....) THEN 1
ELSE 0
END
I need to put these conditions in config table and generate dynamic sql.
What is the best way to do this? especially, 3rd condition with OR logic with multiple columns involved.
I have a virtual server (VMware ESX) with 64GB RAM running a single instance of SQL 2012 SP1. The max memory config is set to 59392 (58GB).
The Page Life Expectancy for this server has been averaging well under 10 mins for the last few days, according to our monitoring.
I have been checking the amount of data in the buffer cache periodically during the day with the below query, which seems to show that there is never more than about 10GB of data at any one time, frequently dropping below 5GB:
SELECT COUNT(*) AS BufferPages,
CONVERT(decimal(10, 2), COUNT(*) / 128.0) AS BufferMB
FROM sys.dm_os_buffer_descriptorsWhy would the amount of cached data be so low (and cause so much churn)?
I am aware that other things will require some of that memory (plan cache etc.) but with Max Mem of 58GB, I would expect there to be a much higher amount of actual cached data at any one time. I did the same checks on another VM with the same amount of RAM/Max Mem setting, and there was 50GB of data in the cache, with PLE measured in hours.
Hi everyone,
Primary platform is 2005 under 64-bit.
I'm trying to figure out what does 'Processor Affinity' and 'I/O Affinity' means when you're viewing server properties. We've got eight processors.
Thanks for your comments,
I have recently upgraded my databases from SQL 2000 to 2005. In 2000, I could set the network affinity so that sql server was only accessible from one of the two network cards. I cannot find how to do this in sql 2005. Is there a way?
In my installation, I have two network cards in each server. The "A" network adapter connects to the "A" hub, and the "B" adapter connected to the "B" hub. Traffic on trhe "B" hub is my private, non-routable network, This is where I want the SQL Server traffic to run. The A hub traffic is the public network. This gives me the ability to isolate SQL Server from the outside world.
Hello Friends,
I'm trying to set affinity to mssearch.exe in our Windows 2000 Advanced
server (4cpus), but i am getting an "Access denied error". I checked the login which has administrator rights to the box.
It would be a great help if anyone can tell how to fix this.
Thanks

We are currently looking at consolidating 10 servers into one cluster server.
Some servers may be busier than others. Is there any reason to split them up and give the busy databases specific CPUs or is it always better to have them on one instance?
On NumaNode1 and NumaNode3. I can see all of the CPU's there but the checkboxes are disabled.
What could be disabling these?

Hello
I'm using the ForEach File task and masking the files I want to process as ABC??.TXT.
It all works well until I drop a file there like ABC12 Copy.TXT, which I don't expect to be process, but the loop still picks it up. Am I using the wrong wildcards?

sorry for my question, maybe it seems un professional but I need to know the answer,
is it possible to enter the data in a sql table in a specific format and how it could be?
for example I want to have a mask in the table to enter the data in this format ##.## so it will not accept any other data to be typed in without this format.

Hello, I have this Access 2K query that I need to re-create in MS SQLServer 2000, so I'm using the Query Analyzer to test it.One of the Access fields stores the home phone number. In the Accessquery, if the phone number is null, it fills it up with zeroes"000000000." If the phone has an input mask, it only gets the 9 numbers(area code included) and if the phone number's good (all numbers) thenit leaves it alone. That Access query is using immediate ifs toaccomplish that task.Does anyone have any idea how to copy this behavior into SQL Server2000? I've using the CASE statement but so far my code is not correct.I get stuck in the input mask. This is the Access code:HomePhone:IIf(IsNull([HomePhone]),"0000000000",IIf(Left([HomePhone],1)="(",Right(Left([Homephone],4),3)& Right(Left([Homephone],9),3) & Right([HomePhone],4),[HomePhone]))Thanks for all your help.JR.

I have statement which is comparing a smalldatetime column to literal string as follows:
sales_date ='21-9-2004 0:0:0.000'
when I run the statement in query analyzer it bombs out with:
Server: Msg 296, Level 16, State 3, Line 1
The conversion of char data type to smalldatetime data type resulted in an out-of-range smalldatetime value.
If I alter the format of the date literal to '2004-09-21 00:00:00' the statement works.
Is there anyway of forcing the statement to treat '21-9-2004 0:0:0.000' as '2004-09-21 00:00:00' without modifying the statement itself ?

Currently have a single hard coded file path to the SSRS config file which parses the file and provides the reporting services web service url. My question is how would i run this same query against 100s of servers that may or may not share the same file path as the one hard coded ?
Is there a way to query the registry to find the location of the config file of any server ? which could be on D, E, F, H, etc.
I know I can string together the address followed by "reports" and named instance if needed, but some instances may not have used the default virtual directory name (Reports).
Am I going about this the hard way ? Is there a location where the web service url exists in a table ? I could not locate anything in the Reporting service database. Basically need to inventory all of my reporting services url's.
Hello all,
I'd like to know what's considered a best practice in the following scenario...
We're in the process of converting DTS to SSIS, our current SQL2K setup has one DTS package per database, each database and package are mirror images of each other, with the exception of connection properties and the files path's they pull from. (Occasionally there may be a one off Execute SQL Task that differs from package to package...but this will be handled in a different manner outside of the package from this point on)
From a administration perspective this has been somewhat cumbersome, as every time there is a schema change we need to update the transformations in each individual package...after updating 120 packages my index finger has a bad case of carpel tunnel!
My thought with SSIS is that I can create one package, with many configuration files (one for each database).
Now my question is, 1) is this a good idea? 2) Anytime we create a new database (New Customer = New Database) and need to create a new xml config file, do I have to create the config in BIS/SSIS package then redeploy the package?...or Can I simply add a new config file to the appropriate directory and reference this config in the scheduled job?
Any suggestions are greatly appreciated!
Hi,My application is acting weird and the research I've done leads me to an answer why it's breaking, but not how to fix it.My web app is hosted by a remote company. I have the main website sitting in the root web directory and in a subfolder I have another application that will handle login and updating the content in the SQL 2K5 backend (not an Express DB).The website itself is able to pull in informaiton from the DB without any trouble, so I know it's able to connect to the DB and everything is peachy. The login app though is acting as though it can't get to the DB. I've applied the ASPNET schema to the DB using the aspnet_regsql.exe from the framework and the login application is using the same connection string as the main website.One thing to note here is that the website and the login app have seperate web.config files since they were developed as different projects.With my customized provider defined in the web.config for the login app I get this error on page load:"Parser Error Message: It
is an error to use a section registered as
allowDefinition='MachineToApplication' beyond application level. This
error can be caused by a virtual directory not being configured as an
application in IIS." If I comment out the custom provider, the page loads but when I try to create a user it tells me that "...the SQL Server couldn't be contacted. This may be because it doesn't accept remote connections." Thing of it is that it's not a remote connection and it's the same connection string and db as the other site.Now, the research I've done points at the two different web.config files, which makes sense. But how do I make the one web.config work for both the website and the subdirectory with the login app? Keep in mind that I can't create any new virtual directories or modify IIS since this is a remote hosting company.Can someone help me understand the fix with a little more clarity?
Hi,
I'm kind of the first person at my new company to start a project using SSIS. My question(s) revolves around setup and configuration, maybe even best practices.
1. Connection Manager Config - What are some of the methods you use to config your connection managers? I was planning on creating a folder (C:SSISConfig or something) and keeping a config file for each connection there. That way it would be fairly trivial for each developer to also put said folder on there box for deving.
2. Solution set up - Are people creating solutions for each package or just using one Master solution and adding all the packages to that? Or maybe some combination, like having solutions for different areas of functionality or something..? I'm trying to figure out what the pain points are with different approaches.
If you have any other information or horror stories about SSIS that you think might help, feel free to pass them along.
Thanks,
