Workload Governor Removed
Jan 8, 2007
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

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

Suppose 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

I 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.

I 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
[Code] ....

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'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.

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....

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);
GO

I'm baffled by a problem I noticed yesterday, I have a 3 NODE SQL 2005 x64 ENT cluster which was setup with SSIS and Notification services upon setup. I have gone through patching SQL 2005 with SP1 (initial setup) SP2 and Hotfix 3052 through the last two months and it in the NT applicaiton log that SSIS was patched and started up to 6/15. Yesterday I received an email stating SSIS was not installed by one of our developers, upon logging in a confirmed it's no longer there! I re-installed through ADD/RM Programs SQL 2005 and ran through the SP2 and HF 3052 setup.. but upon scanning the Application logs I can't find any record of SSIS or Notification services being uninstalled. The MSinstaller shows the initial install of both packages, and then the re-install today but there's no log of uninstalling it. Does anyone know where else I can look or has can explain this odd occurance?

Hi all,
I have a problem with alphanumeric codes in SSIS.
I have a sql table with a varchar column which contains codes like '080101000', in my SSIS dataflow I have a lookup against this table and the column whith the code is used as output column for my lookup transformation.
In the advance editor the output column datatype is DT_WSTR, but when the code contains only numbers like the code '080101000' the first '0' is removed! It's like the code is at some point transformed to numeric and then inserted in the output column as a string. This in nonsense!!
Does anyone have an idea how to avoid this ?

We have a publisher that got red-crossed(Run to problem). I decide to remove and recreate it. However, after remove it, the publisher still stays in Replication Monitor. The remain thing has no distributor and logreader, but only snapshot agent. When to check the property of the agent, we got a error message basically say the job does not exist, which makes sense.
Now, it does not show up in any places, except Replication Monitor. Well, it cannot be removed from Replication Monitor. Can any one tell us how to clear it from Replication Monitor?
Thank you.
More Infor: The replication was set up on 2000.(2000 pub, 2000 dis and 2000 sub) with 2005 Management Studio, and the publication was removed with 2005 Management Studio.

According to SQL Server 2005 Book Online, the following "Important" note applies to SET_ANSI_NULLS and SET_ANSI_PADDING:
"This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature."
However, these options are automatically inserted in the auto-generated scripts (such as CREATE TABLE) in SQL Server 2005 Management Studio.
I am working on new scripts that include these options. What are the replacements for these options? Does the above note apply to ALTER DATABASE options? Please give me advice!
Thanks!

Hi,
I Recently uninstalled Visual Studio 2005 and SQL Server 2005 Tools from my machine, then I installed Visual Studio 2008 and SQL Server 2005 again. this way I can write normal .NET applications with vs 2008 and still be able to develop my reports with the BIDS.
I thought everything was working oke, until I had to modify a report. When I open the report and preview it...it works fine, but when I go back to the Data Tab, it clears out the mdx queries of all the datasets and I get the default blank designer.
I really need this fixed a.s.a.p. otherwise I can't make fixes to the reports.
Can anyone help?
Regards,
Patrick

This SQL is meant to show the changes that will be made, when removing a selected user's email address from a batch.
However, when executed, each row is duplicated, and in the duplication, the semi-colon or comma isn't removed. For example, if I wanted to remove user "sam@mail.com"
The table results displayed would be:
Row 1:
BatchID: 50
ParamName:EmailTo
ParamValue: jack@mail.com;sam@mail.com;frank@mail.com
NewParamValue: jack@mail.com;frank@mail.com
Row 2:
BatchID: 50
ParamName:EmailTo
ParamValue: jack@mail.com;sam@mail.com;john@mail.com
NewParamValue: jack@mail.com;;frank@mail.com
Ideally, it should only display each row once, and not have the semicolon error. It seems to be a union error, because when I comment out the First and second union statements, it runs fine.
-- Delete email address from a.Batch
IF(@EmailAddress IS NOT NULL)
BEGIN
IF(LEN(@EmailAddress) > 0)
BEGIN
IF(@ShowOnly = 1)
[Code] ......

I have installed SQL server 2005 on Win SERVER 2003, then uninstalled and then re-installed but I have found out that the previous instances are still listed and the the previous collation too (I have changed reg setting and and language option re-installation).
It looks like that removing program does not remove completely every object, probably registry values
Do you know how to perform a good uninstallation removing everything (add/remove program does not work properly as written before) ?
Any help will be very appreciated.

I've been building and testing my reports and have found that if I decide that a report parameter should be removed, removing the parameter causes the report to fail.
If I remove a report parameter via the 'Report Parameters' menu, and I also remove the associated data dimension, filter expression and parameter check boxes, when I preview the report I get an error message. It appears the report is searching for the old parameter name even after it has been deleted.
This leaves me with the option of either restoring the parameter as it was, or rebuilding the report from scratch. I've done some investigation and the parameters seem to exist within the XML code that underlies the report despite the parameters being deleted.
Is there a way to avoid this problem?

I am attempting to configure my SQL Server instance to use a service account with the minimum privileges. I thought I had everything configured correctly, when I realized that having the service account as a member of the "SQLServer2005MSSQLUser" Windows Group meant that the service account was now in the "sysadmin" fixed server role. This was not the configuration I wanted.
I went through the Books Online article "Setting Up Windows Service Accounts" and made sure the login had access to the appropriate folders used by SQL Server. Then I stopped the SQL Server service and tried to restart it, without success. These are the error messages:
Code Snippet
SQL Server could not spawn FRunCM thread. Check the SQL Server error log and the Windows event logs for information about possible related problems.
Could not start the network library because of an internal error in the network library. To determine the cause, review the errors immediately preceding this one in the error log.
FCB::Open failed: Could not open file E:MSSQL$STAGINGDatamodel.mdf for file number 1. OS error: 5(Access is denied.).
TDSSNIClient initialization failed with error 0x5, status code 0x1.
TDSSNIClient initialization failed with error 0x5, status code 0x90.
I checked some other posts on this board, and they suggested the problem might be that the "VIA" protocol was enabled. I checked for this protocol in the Configuration Manager, and it is DISABLED in both the SQL Server 2005 Network Configuration and the SQL Native Client Configuration. What else could be causing this error?
The errors do not occur when I add the service account back to the "SQLServer2005MSSQLUser" Windows Group. The SQL Server service starts successfully when the account is back in this group.
Here are my answers to the questions posted at the top of this board:
What is the MS SQL version? - SQL Server 2005 SP2 (9.00.3054.00)
What is the SKU of MS SQL? - Enterprise Edition (SKU ID: 1804890536)
What is the SQL Server Protocol enabled? - TCPIP, Named Pipes
Does the server start successfully? - NO
If not what is the error messages in the SQL server ERRORLOG? - See above.
If SQL Server is a named instance, is the SQL browser enabled? - YES
What is the account that the SQL Server is running under? - Domain Account
Do you make firewall exception for your SQL server TCP port if you want connect remotely through TCP provider? Not applicable, Windows Firewall is not used
Do you make firewall exception for SQL Browser UDP port 1434?

I find that dynamic masking does not work on joining tables in SQL Server 2016 CTP2.1.
For examples, I create the following table:
CREATE TABLE [dbo].[HRM_StaffAppointment](
[StaffID] [nvarchar](11) NOT NULL,
[ApptSeqNo] [smallint] NOT NULL,
[ReportingDept] [nvarchar](10) NULL,
[Code] ...
Then I apply mask on StaffID and RankDesc.
alter [dbo].[HRM_StaffAppointment] alter column [StaffID] add masked with (function='default()')
alter [dbo].[HRM_StaffAppointment] alter column [RankDesc]
add masked with (function='default()')
When User A logged in and query on HRM_StaffAppointment, StaffID and RankDesc are perfectly masked. But User A can remove the masking using another table:
CREATE TABLE [dbo].[staffID](
[staffID] [nvarchar](255)
) ON [PRIMARY]
select a.*
from dbo.HRM_StaffAppointment as a
left join dbo.staffID as b
on a.StaffID = b.StaffID
It looks like a security hole to me, or I'm doing anything wrong?

I enabled logging by right clicking on the control flow and specifying a log provider.
after a while, i deleted the log provider from the tree view and the connection manager it was using from the connection manager collection.
now i cannot open the package.
here are the errors i can collect from the failure;

This occurs when CPackage::LoadFromXML fails. . Visual Studio 2005ProjectsMeds2ImportMeds2ImportImportMedsSubmissionFiles.dtsx 1 1
is there some file to edit or a way recreate or revive the package, even if it means just duping the package into believeing what it wants is there?
as a baseline altertnative, is there any way to retrieve the work?
it consists of a boatload of derived column transformations of way too many columns that i would really rather not rewrite, so if its lying about on my drive somewhere in an xml file that can be used to recreate what i had, it would be just ducky.
thanks
