Performance Issues After Installation Of Sp2.

Jun 28, 2000

We have a program (originally written for sql 4.21) with a lot of embedded sql in it. The program was adapted for sql 7.0 but still uses embedded sql and did run quite well. After we have installed sp2 we noticed a considerable performance decrease. So we traced in order to find the sql causing this. Several statements (from the embedded code) using cursors seems to cause the trouble. When we ran the code in query manager, the access path was good (runtime some milliseconds), when running the code via the embedded-sql-program then same sql statement runs as slow as hell (runtime 3 to 10 minutes). When looking at reads/writes/cpu, it's obvious that the optimizer uses a whole other accesspath. Probably with a lot of tablescans instead of using the right indexes.

Has anyone a similar problem? Also related to sp2? Is this a bug in sp2? Anyone a clue how to work around this? Help...

Does anyone know how to report this to Microsoft, since we don't have direct support from them, only via HP?

MAJOR PROBLEM: New SQL2005 Installation Performance Problem.

Sep 26, 2006

We are experiencing a major issue since upgrading from SQL2000 to SQL2005 over the weekend. Starting today, it appears that the performance of SQLServer reaches a limit every 15 minutes.

Our configuration is as follows:

Window Server 2K3 x64 Enterprise

SQLServer 2005 x64 Enterprise

HP DL585 with 4 dual core Opterons

32 GB of RAM

2 TB EMC SAN

At first, I thought there was a memory pressure problem, since I had the default max memory set. After changing the max memory to only 25 GB (out of 32 available), the issue went away temporarily. However, after 15-20 minutes, the number of batches/sec dropped in half, and remained after half until I changed the max memory setting again. Over the course of the day, I was able to fix the issue each time by just changing the max memory by 1MB. (From 30,000 to 29,999 and back from 29,999 to 30,000). Each time, the batches/sec counter immediately doubles and remains there for about 15-20 minutes. None of the SQL statements have changed since upgrading.

I have found this post, which talks about a similar issue at the end of the thread:

http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=746299&SiteID=1

Any ideas?...this is frustrating to no end.

Thanks!

MSDE Installation Fails Due To Detection Of Previous Installation

Jul 23, 2005

Please help,I am trying to install MSDE 2000 so that Backup exec will run on thisserver. I have gotten so far as to find an entry in my SQLSTP.TXT filethat says that c:mssql7 was detected so the install fails.Now, to start with there is no directory called C:mssql7 on thisserver. I have gone through all MS articles on manual removal of SQLserver and instances. I have searched the registry for mssql7 andremoved any keys that matched, as per MS article I have searched onSQLBOOT.dll and it is not present anywhere on my system and I still getthe same results.2:07:44 Begin Action: Detection12:07:44 SQL Server version already installed: 7.00.62312:07:44 Previous Install SQL Path: C:MSSQL712:07:44 Previous Install SQL Data Path: C:MSSQL712:07:44 End Action Detection12:07:44 Begin Action: ODBCLocked12:07:44 End Action ODBCLocked12:07:44 GetDefinition returned: 112:07:44 Previous SQL Server ProductType: MSDE [0x4]12:07:44 This combination of Package and Operating System allows a fullproduct install.can anyone think of anything here..what else could be causing the server to think there is a previousversion of SQL 7 on this box!!!?

Express Installation Fails With Invalid Installation Package

May 3, 2006

I get an error when trying to install the SQL Native Client. It
says it cannot find the installation package and to use a valid copy of
'sqlncli.msi'. I've downloaded the Express setup twice and get
the same error from both of them.



I'm attempting this in a VMWare session setup for Windows 2K, Advanced
Server. I am trying to test my installation and setup
procedures. This is not a production setup, just install testing
and documentation. I have allocated only 272MB to the VMWare
session, which is why the system doesn't meet the recommended settings.



Any help would be greatly appreciated.

Extremely Poor Query Performance - Identical DBs Different Performance

Jun 23, 2006

Hello Everyone,I have a very complex performance issue with our production database.Here's the scenario. We have a production webserver server and adevelopment web server. Both are running SQL Server 2000.I encounted various performance issues with the production server with aparticular query. It would take approximately 22 seconds to return 100rows, thats about 0.22 seconds per row. Note: I ran the query in singleuser mode. So I tested the query on the Development server by taking abackup (.dmp) of the database and moving it onto the dev server. I ranthe same query and found that it ran in less than a second.I took a look at the query execution plan and I found that they we'rethe exact same in both cases.Then I took a look at the various index's, and again I found nodifferences in the table indices.If both databases are identical, I'm assumeing that the issue is relatedto some external hardware issue like: disk space, memory etc. Or couldit be OS software related issues, like service packs, SQL Serverconfiguations etc.Here's what I've done to rule out some obvious hardware issues on theprod server:1. Moved all extraneous files to a secondary harddrive to free up spaceon the primary harddrive. There is 55gb's of free space on the disk.2. Applied SQL Server SP4 service packs3. Defragmented the primary harddrive4. Applied all Windows Server 2003 updatesHere is the prod servers system specs:2x Intel Xeon 2.67GHZTotal Physical Memory 2GB, Available Physical Memory 815MBWindows Server 2003 SE /w SP1Here is the dev serers system specs:2x Intel Xeon 2.80GHz2GB DDR2-SDRAMWindows Server 2003 SE /w SP1I'm not sure what else to do, the query performance is an order ofmagnitude difference and I can't explain it. To me its is a hardware oroperating system related issue.Any Ideas would help me greatly!Thanks,Brian T*** Sent via Developersdex http://www.developersdex.com ***

SQL 7.0 Installation W98

I have problems after installation in W98 of the Desktop.

In Enterprise Manager when I try to connect to the server gives the following error:

Assertion failed!

line: 119

Expression: Count

after I click on RETRY and gives the error:

a connection could not be establish to TEST05 - [SQL-DMO]code execution exception:

Please verify SQL SERVER is running and check your SQL Server registration properties and try again.

I check, and in Service Manager is TEST05 - MSSQLServer - running.

Also in Query Analyzer gives an error:

Assertion failed!
program c:mssql7innisqlw.exe

after I click on RETRY and gives the error:

This program (ISQLW) has performed an ilegal operation and will be shutdown

ISQLW caused an exception 03H in module MSVCRT.dll at 0177:7800...


Where is the problem? From wrong installation or W98?

Installation Of SQL 7.0

Nov 13, 2001

Hi:

We ran SQL Replication in Production SQL 7.0 with SP1. We encountered some problems. We ran the same tests in QA which used SQL 7.0 with SP1. The problems were gone.

Both Production and QA used SQL 7.0 with SP1 but they came from different resource CDs. Production one was installed from Microsoft Select CD in 1998. I did not recall the CD which was used for QA.

It indicated those two SQL 7.0 functioned differently and Production on had a bug in it. Can somebody to share with me a detecting tool and a criteria to find out where is wrong in the Production SQL 7.0?

Thank you.

I am new with SQL and have a question regarding SQL Connections. I have 2 Win2003 Servers(tom and Jerry) setup with Microsoft Cluster installed in Active-->Active Mode. Also, on both of these servers, I have SQL 2000 installed in Active-->Active mode as well. So I installed SQL2000 on Tom first and gave the SQL server name of Dog1 which has and IP assigned to it, at the same time I gave an instance name of D1. So now my SQL on Tom server reads Dog1D1. I did another installation on Tom and gave it Dog2D2. Than I went and installed SQL again on Jerry, this time and gave name of CatC3, and CatC4.

Now in my DNS, I have Dog1, Dog2, Cat3, Cat4 defined with an IP I assigned.

Problem I am running into is I cannot connect my application or make and ODBC connection to Dog1D1, Dog2D2, Cat3C3 or Cat4C4. I am getting Server not found message.

Can anyone help me and tell me where I am going wrong, as I need to get this app up ASAP.

What should the entries in the connect to server window be for me to get to the next stage where I can start building databases.
At present, I tried local or localhost and windows/sql authentication.
Still can not get to the management studio window.
Any thoughts please?

SQL CE 3.5 Installation

Hi,

I had SQL Mobile installed on my XP PC. As I wanted to use INSERT IDENTITY, I uninstalled SQL Mobile from my Pc. Now I see two problems:
1. Even after uninstalling SQL Mobile and rebooting my PC, I still see SQL Mobile option when I start SQL Server Mgmt Studio. Any reason why?

2. I then installed SQL CE desktop runtime (nearly 1.8 MB) and rebooted my Pc. Now when I go to Query Analyzer, I still cannot use IDENTITY Insert.

3. There seems to be two versions of CE download: one for desktop and one for mobile. Can anyone let me know which one I should download for desktop? And for deployment on device which version I need to download?

Can't Use This Or That. Installation And IDE

Mar 19, 2008



I started migrating from C++ and want to use C# with an embedded database in my application. My search pointed to MS SQL Server 2005 compact edition. I go to download it and seems like there are two versions to choose from:

MS SQL Server Compact Edition 3.5
Can't use it because it requires Visual Studio 2008. I have VS 2005 and don't want to spend another chuck of money just to work around this one problem.

MS SQL Server Compact Edition 2005
Can't use it because Vista is not a supported operating system for development and it requires Active Sync 4.0 which also will not install on Vista.

I am just screwed because I am using Vista as my development machine, even when I am not targeting Vista for my applications?

Is there anything I can use for a simple embedded data storage solution with VS 2005 and Vista, using C#?
