Performance Decrease After OS Upgrade
Jul 23, 2005
We were running a 4 processor server with 8 GB RAM and 800GB hard disk
space on Windows 2000 server and SQL Server 2000.
Recently we have upgraded the server to 8 processor and added another
800GB. 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 what
it was giving before the upgrade.
It seems that multiprocessing is not ocurring.
The model of the server is HP DL740
The OS is installed in a built in array(5i controller) of the server
and the SQL server is installed in a external array(6400 controller).
I will really aprecite if anyone can give any clue to improve the
performance.
Thanks in advance.
Taw.

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

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!

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.

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?

A want to user a procedure to decrease a number in a col. by 1 each day.
I need some type of operation
then a job has to run the procedure to decrease a number once a day.
I don't know how to go about the operation? I am going to the SQL Query Anylizer to help me run the script to test it. I have in a col. of 201 numbers, and I will subtract 1 from each day from all recorders. I guess you could call this a count down or timer. Does this code work for me?
Thank You,

Hello Guys,
Just wondering if someone can help me decrease the size of mdf and ldf files. In the past production database "NewUniverse" had been allocated space of 100 GB for mdf file and 8 GB of ldf file. However the data file has only used 30 GB of data. But now due to disk space related reason, I tried to decrease the datafile size from 100 GB to 40 GB. But I am not able to do it.
Any help in this regard would be appreciated.

I have a database that the transaction log grows about 1 GB per day. I would like this size was decreased daily. Does anyone have any suggestions?
Some friends told me that after the Full backup that is done daily, I should perform a backup of transanction log with option to truncate and after, make a shrink in the database. That is exactly what should be done?
Thank you,
Best Regards,

Hi,
My DB size (Right click on DB Name, Data Files tab, Space Allocated field) was 10914 MB.
I delete a huge table (1.2 million records * 15 columns).
I checked the db size again. It didnt change.
Shouldn't it decrease because I delete a huge table ??

This is an example of my data:
Col1 Col2 Col3
1 LONGDESCRIPTION1 111
1 LONGDESCRIPTION1 222
1 LONGDESCRIPTION1 333
1 LONGDESCRIPTION1 444
2 LONGDESCRIPTION2 XXX
2 LONGDESCRIPTION2 YYY
2 LONGDESCRIPTION2 XYZ
2 LONGDESCRIPTION2 999
This is an example of what I want my report to look like (ill put row numbers to help identify)
Col1 Col2 Col3 Row Num
1 LONGDESCRIPTION1 111 1
222 2
333 3
444 4
Subtotal Col3Sum (PAGEBREAK)
2 LONGDESCRIPTION2 XXX 5
YYY 6
XYZ 7
999 8
Subtotal Col3Sum
The Settings:
I'm currently using a single TABLE DETAIL ROW with HIDE DUPLICATES in Col1 and Col2.
The LONGDESCRIPTION field can be expected to take 2 row heights worth of space because it wont fit.
I've also got CAN INCREASE TO ACCOMODATE CONTENTS and CAN DECREASE TO ACCOMODATE CONTENTS selected.
The Problem:
When Printing/PrintPreviewing Page1, the Height of Rows 2/3/4 ARE THE CORRECT SIZE (only 1 row high, meaning that can decrease to accomodate contents works).
BUT when Printing/PrintPreviewing Page2, the Height of Rows 6/7/8 FOLLOW THE HEIGHT of ROW 5 (two rows high, meaning that can decrease to accomodate contents DOES NOT WORK).
Rows 2/3/4 has the same Row Height as Row 1 ONLY ON PAGES after Page1.
Rows 6/7/8 has the same Row Height as Row 5 ONLY ON PAGES after Page1.
Can decrease to accomodate contents does not seem to be working for Pages after page 1.

I have a database consisting of two main tables and 12 sub tables.
This was leading to increase in database size. So we thought of storing the sub tables data in the main tables in form of xml in a column of varchar(2000) type.
So we created a new database that only had 2 tables and we stored the data of the sub tables in the new column of the main table.
Surprisingly we saw that the database size increased rather than decreasing .

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.

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

2. Use a .NET windows service with timers to call SqlClientConnection
above, which way would be faster and get a better performance?

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 2000 -> SQL 2005 upgrade on windows server 2003 ... We've done numerous side by side types of upgrades which have the advantages of being able to migrate things at a slower pace with limited downtime. I have a situation where it seems like it would be the least amount of work to do an in place upgrade involving 22 transactional in-house developed databases and associated in-house developed applications. There's no replication, no DTS packages, nothing I can think of that would complicate the upgrade. I was wondering if there's people out there that have done lots of these and haven't had any problems OR if there have been lots of problems. Anyway, any advice would be appreciated.

Hi,
I plan to move my servers from Windows NT and SQL 7 to Win2K Advanced Server and SQL 2000. I am not going to upgrade the windows server, as I have been told this isn't a good thing. Therefore, I plan to detach my databases, install win2K, install SQL 2000, and then attach the databases. I've read that this works fine, but I am curious as to whether or not I can do this with master and msdb(as I want to keep all logins, jobs, etc). Is this possible? Also, is my plan decent? it seems to be the easiest way to me...
Thanks!

Hi All,
I am upgrading sql 6.5 to 7.0. The 6.5 database has 3 data files. Do I need to create 3 datafiles in version 7.0 after the server has been upgraded? Before I do the upgrade on the production server, I want to do a test on another machine loaded with sql 6.5, Do I need create 3 data files on 6.5 to to load the database from the production server before I upgrade the test machine to sql 7.0?
Thanks in advance,
