Performance Problems Post 6.5 Upgrade
Feb 19, 2001
We are in the middle of an upgrade from 6.5 to 2000 and are experiencing terrible performance. The trouble seems to be with compilation times - we have lots of SQL that compiles much more slowly in 2000 on a 933 Mhz server than it does in 6.5 on a 200Mhz server. The SQL is very complication and can take up to 20s to compile in 2000. And, to make matters worse, much of our SQL is not in stored procs and so has to recompile on every execution. It looks as though we are going to have to spend an enormous amount of time re-writting SQL and converting the application to use stored procs.
Have others seen similar behaviour? Does 2000 really take so long to compile SQL or have we got something wrong?
All help much appreciated.

Greetings,
I have a client whose DBA upgraded their SQL 2000 database to SQL 2005. They still have it running in 8.0 compatibility mode, for various reasons, and would like me to help them develop a migration strategy to get them to full 9.0 compatibility.
My question is: can I run the Upgrade Advisor on a SQL 2005 engine database running in 8.0 compatibility mode and get anything useful? I already know there will be some issues with existing DTS packages but it would be nice to catch any other issues in advance.
I know that the Upgrade Advisor was run before the upgrade took place but to my knowledge the report was not saved and none of the recommendations were followed.
Any help would be greatly appreciated.
Cheers,
Lon

Hi,
I am unclear on Microsofts policy regarding support for DTS and packages that have been imported (but not migrated) to SQL 2005.
The upgrade advisor states
SQL Server 2000 Data Transformation Services
Advisory
SQL Server 2000 Data Transformation Services is deprecated You must completely migrate existing SQL Server 2000 Data Transformation Services (DTS) packages to SQL Server 2005 Integration Services packages before support is withdrawn.
Source Type: MSDB Package
What does this really mean? What will happen to the importing of legacy packages and this whole area within Management Studio? Will these 2005 features no longer be supported? What will happen to the Execute 2000 task? If I upgrade a SQL 2000 instance post 08/04/08 does this mean that I won't receive support from Microsoft even though the package post installation is in SQL 2005. Will the new dts designer in the feature pack be taken away/withdrawn?
To say DTS packages will no longer be supported is a very dramatic statement with far reaching consequences. How is this going to be effectively implemented? Is there really going to be no backward compatibility support in Katmai?
Cheers, James

My Original Post
I have to query n table(NLRImports) using the Distinct keyword, to retrieve a set of ID numbers. ( "Select DISTINCT id_nbr from NLRImport" ).
Now i want to use those values i retrieved, to process the records in the table(NLRImports) 1 by 1. How do i use those ID no's i retrieved as Variables or parameters for my next query?? If this makes sense?
----------------------------------------------------------------
First, thanks for the response.... now here is what im trying to do.
I created a simple application in delphi to import information to a table in MSSql2005. This is some of the resulting columns...
date | id_nbr | account_nbr | sub_account_nbr | ... etc
-------------------------------------------------------------
Now there will be several entries with the same id no but on different dates, so i take it dates would rather be my pkey.
Then i need to take one person's entries(i work on id_nbr) and go thru all the entries taking the earliest date and comparing all the other entries for that person to the first date and select all the dates more than 19 days after the first date and less than 91 days from first date and place it in a new table.
I used cursor s and while loops to kind of get it going but i know that cursors are not really recommended use but the performance implications dont bother with this particular job.
What other ways should i be using to accomplish this?
thanks, i hope this is clear...

Hi,
Hope somebody can help, because I am facing a major crisis...
We, at a customer's site, migrated many SQL Server 6.5 databases to 7.0, and the performances dropped down. We identified the problem was the stored procedures... Some procedures use parameters. If you substitute the parameters value manually the proc runs very fast (that is write the values directly into the queries), but if you leave the parameters, it runs very slowly (the worst example we have goes from 6 seconds to 6 minutes, for a single SELECT !). This phenomenon did not happen with 6.5. Is there a solution ? Thanks for your help !

We had a Server, 4CPU, 4GB RAM running NT4 and SQL7.
The system drive (C:) was trashed and Win2000 Adv Serevr installed followed by SQL7.
We restored the Master and MSDB in order to get all out security and user databases back. Everything works fine, except that we were expecting some form of performance improvement running under Win2000. Are our expectations wrong or have we missed something ?
The processes took 1hr 35 mins under NT4/SQL7 and take roughly the same under Win2000/SQL7.
I have run perfmon and observed higher disk queues, so I have lowered max async IO, but this hasn't improved performance eitehr (but queues are better).
Many thanks

We were running a 4 processor server with 8 GB RAM and 800GB hard diskspace on Windows 2000 server and SQL Server 2000.Recently we have upgraded the server to 8 processor and added another800GB. The OS was upgradded to Windows 2003 enterprise edition.All the processor are 2.5GHz Xeon preocessors.After upgradation the performance of the server has gone down from whatit was giving before the upgrade.It seems that multiprocessing is not ocurring.The model of the server is HP DL740The OS is installed in a built in array(5i controller) of the serverand the SQL server is installed in a external array(6400 controller).I will really aprecite if anyone can give any clue to improve theperformance.Thanks in advance.Taw.

Hi.
I have successful upgraded from Windows 2000 / SQL Server 2000 to Windows 2003 / SQL Server 2005. Here is the process:
- Install Windows 2003 / SQL Server 2005 on new VM instance
- Detached SQL Server 2000 database -> Copy data to the new server and Attached to SQL Server 2005
- Run scripts to restore user login
- Change Compatibility level to: SQL Server 2005 (90)
Now, open 3rd party application and connect to the new database server (via IP address), the application was connecting ok and access data without no problem. However, database take more than 5 minute to connect/open instead of 30sec via the old the server?
Please adivse what could be the issue? Thanks!

If you have your Data, Logs, System and TempDB all in VMDK's and those VMDK's are formatted to 64K and then reside on Clustered Storage that is formatted as 4K, which is then running through a SAN controller that is reading and writing in 2MB chunks, is there value in formatting the SQL drives as 64K? Also, would it be better to format the Clustered Storage as 64K? Is this a situation in which formatting the SQL drives as 64K is becoming a moot point?

If I'm on a remote machine, meaning a computer not in the WSFC cluster, and I open SSMS 2014, point it to a SQL Instance, and open activity monitor:
1. I get all the panes and charts except % Processor Time.
2. Then, if I authenticate to the cluster's domain by mapping a drive with valid domain credentials, I'm free to put performance counters in the Perfmon - - - but SQL Activity Monitor shuts down with“The Activity Monitor is unable to execute queries against server SQL-V01INSTANCE1..Activity monitor for this instance will be placed into a paused state.Use the context menu in the overview pane to resume the activity monitor.
Additional information: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))(Mscorlib)”
3. Of course, the Activity monitor can't be resumed via the context menu. Removing counters and closing the perfmon do not work. I dropped the mapped drive and rebooted the machine. That brought back 95% of the information in the Activity monitor.
4. Further experimentation showed that any mapping of drive shares present on the SQL Server to the computer running SSMS cut off functionality of the 'overview' pane in the remote machine's SQL Activity monitor -- the monitor that had been trying to watch the server offering the shares.

Alright so here is what I am trying to do.
I have a form that someone fills out it has a text box as title, and a drop down box that is a category, and then a text area that is for their explanation.
On the back end I am using a stored procedure called sp_store_bkm. When I execute this it works just fine and puts the data that I put in it into the to table below is the Stored procedure code:
ALTER PROCEDURE sp_store_bkm @oID nvarchar OUTPUT, @oTitle nvarchar(50), @oCategory nvarchar(50), @obkmtext nvarchar(MAX)
AS BEGIN INSERT INTO tbl_bkms(Title, Category, bkmtext) VALUES(@oTitle, @oCategory, @obkmtext)Set @oID= SCOPE_IDENTITY() END
Now on my front end it comes up with an error in the lower left (erros on page). When I click on the error for details it seems like it is coming fromt he connection string. I cant find anything wrong with the connection string. Below is my code for the aspx page.
<%@ Page Language="VB" MasterPageFile="~/MasterPage.master" Title="Untitled Page" %><asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<script>
function Submit2_onclick() {

Greetings friends:
I am a student at DePaul University in Chicago, IL. We have a big db project tomorrow and I'm proud with the work I've done so far, I've designed my own db and tested it using queries and such. Pretty good for being introduced to SQL just a couple short months ago. Anyway, I've sort of run into a wall here. I need to have an attribute of a table be computed from others.
I'm working with 2005 Server Management Studio and I have found the computed column specification under the column properties tab. I know that I have to enter a formula, but I'm just not sure on what to do. I have a CHG_HOUR attribute in a table called "EXPERTISE" which signifies how much a consultant charges per hour, based on what he exactly does. I also have a JOB_HOURS attribute in a JOB table (that links my CONTRACT table to CONSULTANT). I want to basically give a formula that multiplies the CHG_HOUR from the EXPERTISE table by the JOB_HOURS in the JOB table. Any suggestions on how I might do this?
Thank you in advance for your response, and hopefully with more practice and courses, I can be the one helping people like me on these boards in a few years.

I have a question about the post SP2 GDR that just came out in the last day or two. My laptop only has the client tools installed, not the server components (except for the SSIS server component). Is there any need for me to install this GDR? Does it impact the Management Studio code which views maintenance plans on remote SQL Servers or anything?

I am developing an application using Visual Web Designer (language VB) with a SQL Server 2000 back end.
Within my logic I have a point where I want to say "Run SQL procedure GEDFinish". GEDFinish can take several minutes, and I don't need to wait for it's results - it would be fine if it ran overnight. I can easily check whether GEDFinish has run from the database, in situation where my application logic needs to know if it has already run.
Currently I only know how to run a procedure under the direct control of my web program, but with GEDFinish this fails due to timeouts. (This will be worse in the production site). What I really want to do is to have my web program submit "Exec GEDFinish" to the SQL agent, and then forget about it. It would be even better if I could build a script for the SQL agent, for example "EXEC GEDFinish Parameter=7"
Help! How do I do this?
Thanks, Robert Barnes

Sorry it is my second posting , I am trying to find answer to my problem
Hello everybody.
I have problem with mail

B) SQL2000 sp2 Standard edition 3072 MB memory
C) SQL2000 sp2 Enterprise edition 2048 MB memory
All servers use same mail profile and they all run under same account MYDomainsvcSql2000 for server and agent and connected to same mail server
1. server C run fine
2. servers A and B could stop mail service during the day and the only way to restart it is to open EM and retype password for Sql server account (it will force Server and agent restart)
Any idea ?

I was hoping there would be a newbie section in here... But I'll post anyway (And sorry in advance if its a really dumb question)I am using VWDE and have a SQL DB which has been imported from one of my existing forums, when it shows in the database explorer its show like belowtblArcade (jdName)tblArcadePB (jdName)etc..etc...What I want to know is why this DB has (jdName) after the Table name and my other DB's shown don't?? They are just shown as tblArcade
tblArcadePB etc..etc.. My main questions are "How do I remove the brackets from the forum DB" as when I try to preview data in VWDE I get a message Invalid object name 'tblArcade'.I know its to do with this extra bit as it only happens to the tables that have this on the end... Hope that makes sense and someone can help me, if you could reply as if I'm really dumb it would be appreciated
