Hi - does the workload governor kick in when more than 8 concurrent operations take place on MSDE as a whole, or does it kick on each database.
Ie. if I have 8 databases within MSDE - and there is 1 operation happening on each one at any given time, will one additional operation on any of the databases invoke the workload governor across ALL databases?
Thanks,
Mark
Hello,
I am in the process of porting over an application from Access To SQL implementing SQL Server 2005 Express. My intention is to implement this database on a full time server and upgrade to a full blown version of SQL later. Am I correct in assuming that there is not limit on the number of concurrent connections to SQL Server Express since it was stated that the "Workload Governor" has been removed? Or does something else control the number of users that can be simultaneously connected to the server.
My reason for asking is I have 7 machines that need to access the server. I also have 2 databases that need to be accessed from each machine. If there is no limit, I will keep my databases seperate. However, if there is a limit, I will most likely merge the tables into 1 db.
Thank you,
Robert
I'm working on a VB.NET project where we are intending to use MSDE as ourback-end database. The actual number of users is expected to be low and Idon't have any concerns as to whether MSDE will be up to the job (most ofthe time). I'm aware that if we end up with lots of users connecting to oursite at once (which may happen as certain times in the year when people needinformation for deadlines) then the performance governor in MSDE will kickin and slow everything down.What I don't know is how do I find out whether the performance governor haskicked in?I would like to know how to monitor this so we can make an educated decisionas to when we need to migrate to a full version of SQL Server (if at all).Can anyone point me in the right direction for finding this out?thanks,Brian Cryer.
View 2 Replies View RelatedSuppose I create a DTS package (I am an old timer from SQL Server 2000 days but I suppose with 2005/2008 integration services there is a similar concept of package) which essentially reads data from a set of csv files, transforms it, and loads it into a SQL Server database. There are two scenarios:
i) The transformation involves applying functions on the columns before loading to the database.
ii) The transformation involves joins of data from multiple files.
My question is, can I run this DTS package on a machine which does NOT have SQL server installed for scenario i) and scenario ii) above? The idea is to distribute the actual processing across a set of computers to take off load from the main database server. If it can be done for either case then can u please explain how? Thanks in advance for your help.
Hi, I need some help about a project I'm working on.
I'm working on a project (based on MS SQL Server) that will involve a lot of clients, each one constantly querying the server.
Just to have an idea of the project, I'm talking of about 2000 clients, each one queries the database 3-4 times per second: a total of 6-8000 queries per second.
The database is reached through Internet and every client uses a dedicated DSL connection.
My questions are:
- What is the maximum workload of a Microsoft SQL Server?
- What happens when the server workload reaches 100%? is there a queue? and what happens when the queue is full? is it possible that the server goes out of service due the excess of work?
- What are (more or less) the hardware requirements for such a server?
can anyone help me, at least telling me how to find these answers (web sites, books, ...)
thank you for you support
Hello,- Is any body aware of a random workload/query generator such as theTPC-H query generator (QGEN) ? I am looking for a query generator thattakes a schema as an input, and produces several queries.I need it mainly for performance evaluation. the generator I am lookingfor should produce SELECT queries, including joins, and not only INSERTINTO, DELETE, UPDATE queries such as the "SqlQueryGenerator" athttp://www.tucows.com/preview/297930ThanksRegards,Abdur-Rahman
View 2 Replies View RelatedI have a specific job that should be run with a decreased memory usage when the workload is heavy on the SQL Server.
This is a heavy job that has no specific requirement when it comes to response time.
It is important that the rest of the application shouldn’t be affected with longer response time when this job is running.
How can this job bee handled from the application, without having to create a separate batch job.
We are using Sql Server 2008 R2. We are planning to move to 2014 either through in-place o side-by-side. Mostly side-by-side.
Here first we want to test that 2014 and availability groups. First we are doing in dev box to test. Also we need asynchronous replica because just we need to use that as reporting server.
We want to take work load. For the dev boxes, the applications doesn't connect. Then in that case what the people will do.
If We take database backup from prod to that dev and run some queries in the loop and run the trace for some time and do either in-place migration or side-by-side migration and use the same back to restore and doing the running the same queries and compare this trace to previous trace will work?
I know that the query governor works off of estimated query plans, but the estimation is usually so far off from reality that it might as be generating a random number to determine whether a query should run.
Right now I have query governor set at 300. I've been able to run queries that take more than 10 minutes without any complaint from query governor.
What's really annoying though, is that it has also blocked queries that take less than a second to run. It blocked a query for having an estimated executing time of 338 seconds. When I set the limit up to 400, the query ran virtually instantly.
Is this just how query governor is suppose to work? Is there any way to make it work better?
I have enabled the query governor on our SQL2000 SP2 server with athreshold of 3600. Now, some of the maintenance jobs fail due to thelimit being to low (e.g. one of the user databases integrity checkfails nightly).I have tried to put the command 'SET QUERY_GOVERNOR_COST_LIMIT 0' justbefore the line in the step which reads 'EXECUTEmaster.dbo.xp_sqlmaint N'-Plan etc'but it has no effect.Does anyone know how to get around this situation without usingsp_configure to change the query governor settings at a systemwidelevel?GC.
View 2 Replies View RelatedI am trying to create a table that would represent a workload for each shop. In order to do that I need to have WorkLoad table and ShopWorkLoad table which is actually just aggregation of WorkLoad.
WorkLoad contains a list of following items:
current orders that are in the process (one select statement)
scheduled orders (another select statement)
expected orders (third select statement) that come through a third-party system
All of this needs to be live. So, for example, as soon as order is added to Order table it should be included in WorkLoad if certain conditions are met. Same goes for scheduled orders (which come from another table). Expected orders will be loaded on a daily bases (based on historical data).
ShopWorkLoad table is aggregation of WorkLoad table.
Currently I did it this way:
Added after insert/update trigger on Order table: when order is created/updated, if it meets certain conditions, it should be inserted in WorkLoad, otherwise remove it from workload if it's in there and doesn't meet conditions
Added after insert/update trigger on Schedule table: when order is scheduled, if it meets certain conditions, it should be inserted in WorkLoad, otherwise remove it from workload if it's in there and doesn't meet conditions
Running daily job that populates WorkLoad table with expected orders based on historical values
Final step is to create an indexed view vShopWorkLoad
My biggest concern is usage of triggers which call pretty complex logic to determine whether item should be added to workload or not.
One other option was to create vWorkLoad view and somehow make it an indexed view but currently I don't see a way of doing that because the query consists of 4 union select statements, below is pseudo example. But even if doing it that way, how to build aggregated indexed view on top of vWorkLoad indexed view?
Third option is to use sql agent job which would run every x seconds (maybe 20) and it would execute all of these queries to populate WorkLoad table with delay of 10-20 seconds, but I am still not sure if this is acceptable to the client.
Fourth option is to create 3 or 4 indexed view where sum of them makes a workload. Then, ShopWorkLoad view would be built on top of these 3 or 4 indexed views, but in this case I don't know how this would affect performance since ShopWorkLoad query would be often queried.
Example of workload pseudo query:
select
WorkLoadType = 'Order in process',
OrderId,
ShopId,
...
from
Order

I was looking for a little insight on Resource Governor. I have a request from my manager to limit the resources a certain third party's DB can use on our system. We allow them to keep a DB on our SQL 2012 server so they can run query's to compare data to their server without linking the two machines.
I was looking into resource manager to perhaps accomplish this task but I'm not real familiar with it. If Resource governor can be used to only allow a DB named UserDB1 to use only 1GB or Memory at any one time?
Or perhaps there is another way aside from Resource governor?
I want to create a classifier function where I can restrict all the logins except two logins for the resource pool.
Case Scenario is : I am creating a resource pool and on that pool I want to restrict the users for that particular pool but IÂ want to allow some of the user IDs full access to that databses so how could I create a script for that scenario.
I want to turn on the query governor cost limit option for 20 minutes so that queries do not run longer than 20 minutes but I could not find any info as if this option would also not allow database backup job or other maintenance jobs to run more than 20 minutes. We have backups (Via RedGate) run over 3.5 hours and others like rebuild indexes and integrity checks even more than 3.5 hours....
SQL Server 2012 SP2-CU1
Windows 2008 R2
I am running a query on SQL 2012 Server with the Resource governer setup for my account to have Max DOP option set to 1.
The query still runs in about 1 minute and the execution plan still considers parallelism.
When I explicitly mention the OPTION (MAXDOP 1) , the query runs in 6 seconds.
How can i tell by querying DMV's whether my query is using parallelism or not?
How to restrict resources usage based on individual Databases in resource governor?
We have many databases in one instance; I would like to restrict resource usage to each database respectively.
I created 2 pools as pool_login, pool_DBNAME, and 2 workload groups as GroupLogin,GroupDBNAME, and also the classifier function.After setup above, I use following statement to check what sessions are in each group .
Even if there are spids which are accessing database DBNAME, I can’t see that they fall into the group GroupDBNAME and pool pool_DBNAME.
SELECT s.group_id, CAST(g.name as nvarchar(20)), s.session_id, s.login_time, CAST(s.host_name as nvarchar(20)), CAST(s.program_name AS nvarchar(20))
FROM sys.dm_exec_sessions s
INNER JOIN sys.dm_resource_governor_workload_groups g
ON g.group_id = s.group_id
ORDER BY g.name
GO
Following is the code to create pool, group,classifier function:
USE master
GO;
-- Create a resource pool pool_login.
CREATE RESOURCE POOL pool_login
WITH
[Code] ....
-- Create a workload group to use this pool.
CREATE WORKLOAD GROUP GroupLogin
USING pool_login;
GO
CREATE WORKLOAD GROUP GroupDBNAME
USING pool_DBNAME;
[code]....
-- Register the classifier function with Resource Governor.
ALTER RESOURCE GOVERNOR WITH (CLASSIFIER_FUNCTION= dbo.rgclassifier_v1);

Hello,
I'm not sure if it's the setup I did wrong, but I can't seem to get my
text datatype in my database to store more than 900 characters.
I'm trying to setup a news database for my website, which will populate
the information into a datagrid. To test, I manually added a news
item in the database through the visual studio 2003 gui. I
immediately noticed a problem as the I was getting an error after a
long news item saying:
"The value you entered is not consistent with the data type or length of the column, or over grid buffer limit."
I couldn't find anthing to set the buffer limit and the datatype is
"text" filled with simple text in the column. As a further test,
I
simply entered 12334567890123... up to 900 characters and still
recevied the error.
I would appreciate someone leading me in the right direction on this one.
Thanks a lot.
I am trying to change the computer name of a machine running MSDE but I get an error when SQL Server starts. With regular SQL when I change the name of a computer I re-run setup and setup fixes this problem. MSDE can only be installed from unattended mode so I can’t rerun setup and fix the problem.
My question is "How do I change the name of a computer running MSDE with out reinstalling MSDE"
We currently have the problem, that all our machines are produced with the
same name and afterwards the name is changed. So we have the problem that
the checksum key for the MSDE isn't valid anymore. As MSDE can only be installed
from unattended mode so I can’t rerun setup and fix the problem. Does anyone
know a solution for this problem ?? A program recalculating the cheksum ??

I'm not sure if this is the correct forum for this this question but I'll give it a shot.
The only db development that I have ever done is in MS Access. I have a project at work that is being accomplished in VB and I need a db engine to use as the back end. Visual studio came with a copy of MSDE. Is this tool worth using or should I invest in mySQL? Are there any advantages to using MSDE over mySQL?
I looking for some guidance here. I have database which has exceeded the 2 gig limit. I deleted some old tables in an attempt to acquire some space. This worked out. However when I look at the size of my *.mdf it still appears in excess of the 2 gigs . I know this isn't true since I deleted 500 megs of stuff. How do i reclaim the space (get the file size to report correctly) or do I need to even worry about it.

objConnection.Open();
objConnection.Close();
I created an instance which is NETSDK
I created a password
I don't know why my server choose the name FRANK i was expecting local.
I have to use FRANKNETSDK or else i can't get my server to Start.
This is the error: Login failed for user 'FRANKASPNET'.

Hi
For quite some time nowI have been trying to give user rights to my MSDE , needless to say the fruits of my labor have turned up very little success.
So far i have tried using the osql commands to grant user access to my database. I have run the stored procedures(sp_grantlogin ,sp_grantdbaccess ) but to little avail!
So now i have taken a new approach i installed the Enterprise Manager. I have just a minor problem with this new strategy , i don't know how to use it!!
This is what i have prensently installed on my system: Visual studio.Net ,Microsoft SQL(MSDE)
and finally the Enterprise Manager.
My Servername is FRANK.
I have created an instance which is NetSDK (FRANKNETSDK)
My SAPWD is Kildare
I have Mixed Mode
Can anyone please tell me how i can use the Enterprise Manager to grant access to MSDE.
I am sure you have all realized from all these insipid post that i have no experience.
So please be explicit in all your details.

Thank you

I have never done anything with databases, so I am a newbie. My goal is to install an ASP.NET forum, but I need MSDE installed. I downloaded MSDE from the Microsoft website. When I run the setup.exe file, I get an error. It says:
A strong SA password is required for security reasons. Please use SAPWD switch to supply
same. Refer to readme for more details. Setup will now exit.
I looked at the documentation but could not find anything usefull, what do I have to do to install it. Thanks in advance for responses.
How does MSDE handle data mangement? Does it come with sql analyser or some sort of database manager?
Thanks.
Hi,
I am newbie in ASP.NET and MSDE arena. I understand that MSDE has no GUI and I need to have MSDE tools to work with it. I have already installed ASP.NET 1.1 and Microsoft.NET SDK 1.1 and MSDE in my Windown Professional 2000 PC and I have run and tested for .aspx and its working perfectly. But I want to use MSDE to create some database driven web applications.
Could you please help me how I can do that? BTW, I installed Microsoft SQL Web Data Administrator and its giving me SQLWebAdminStart.exe Application error and asking for debugging while opening the program. I am stranded what to do now?
I really appreciate your help.

I just installed MSDE off of disk that came with teach yourself asp.net in 24 hours. To get the program started you must go to run and type cmd and wait for the C prompt. I get this far, but I can't get a C prompt. It always comes up C:sql2ksp3> How do I get a C prompt from here. I know it must be something easy that I am just overlooking or forgot.
Thanks

Hi all,
I have a web application that uses SQL Server. I have 6 clients that all use the same SQL Server database structure.
I know have a new client who is using MSDE as there Database. The Database should have the same table structures as the SQL ones.
So my questions are this:
1. I have a backup of the new clients data. How do I attach it to SQL Server?
2. Does MSDE have stored procedures?
3. Can I write stored procedures in a SQL Database, that reference tables in an MSDE database.
4. Can someone point me in a direction, that can walk me through this?
Thanks

Hi,
Well i want to ask, Is this true that
We can use the MSDE on commercial basis for a limited usagage with out paying.
The limited usage means that may be upto 20 - 25 concurent users can be use the Engine at a time.
thx for the comments
