assuming a data driven web application was written, and it is used by a huge number of customers, we can set up some load balancing infrastructure, where multiple web servers run to process all requests. In this case, the database might run on its own machine. But what can be done if one machine is not enough for the database anymore? Is it possible to build some kind of database cluster? And if yes, how does the application work with such a cluster? Is there still ONE connection string or is it needed to query multiple SQL servers?
Long story short; Can a SQL Server database cluster be handled as ONE SQL Server instance from outside, even it is hosted on multiple machines?
And if yes, what edition of SQL Server 2005 is required?
We have a 3 month old quad processor/dual core server running SQLServer 2005 and already it is getting close to hitting the CPU wall.An 8 way CPU box is prohibitively expensive and out of the question. Iam looking desperately for a way to TRULY scale out SQL server...in thesame way that IIS can be scaled out via App Center.The "in the box" solution for SQL Server 2005 scaling out is the DMV.Unfortunately this solution makes the system less available rather thanmore (one server outage takes them all out for that table) and requiresserious rearchitecting of the software to use. Contrast this to IISand AppCenter where each added server makes the system more available,and requires no rearchitecting to work.Before someone says "what you want can't be done in adatabase"...Oracle has an application server middleware product thatlets you do both of the above. Just plug a new server with Oracle onit, and you've doubled your capacity. But SQL Server 2005 doesn't yethave a similar capability.So I read with great interest the following article that talks aboutwhy this is the case with SQL Server. There are two issues that makeit very difficult to do:http://www.sql-server-performance.c...ability_availab...You can create a crude pool using replication, but the performancetimes look horrendous.However, the article also talks about the latest developments in thisfield...specifically MIDDLEWARE that can create a scale out solutionthat is more available and that requires simply adding new servers toscale up.I found two companies which seem to offer this new capability:http://www.metaverse.cc/newsevents.asp?cid=17999andhttp://www.pcticorp.com/product.aspxBoth companies appear to have patents or a patent pending on theprocess. I tried to contact metaverse but got no reply, despite theirrecent press release. I just emailed Pcticorp today to see if I couldlearn more about their product.My question for this group is:Does anyone have experience with either of the two products (or anyothers that provide this capability)?Many thanks in advance for your help.Ian Ippolitohttp://www.rentacoder.com
I have web application for which I need to come up with a scalability plan. The application right now is running on 2 computers, the front end is running Tomcat with JSP (Java Server Pages). The back end is MS SQL 2000
The database is running fine now, but the file size and CPU utilization is growing and I need to figure out a way to distribute this database over several machines.
I looked at MSCE and setting up a cluster, but I think that the solution will NOT work in an intensive enterprise environment. (Am I wrong?). For one thing, there is a hard limit of 16 nodes in a cluster. Also, it requires a shared RAID or FibreChannel Array. These solutions are very expensive. Also, it's not easy to add additional capacity if you reach the maximum of the RAID array. For example, if you have a FibreChannel Array with 8 Terrabytes of capacity, if your DB uses up all 8 terrabytes, you have to buy a whole new enclosure.
One of the major objectives I have is to minimize cost and support unrestricted database growth.
Here is what I would like to achieve. If any of you know of a solution or something that YOU have USED which might give the functionality I require .. I would greatly appreciate your feedback.
Wish List:
1) Run single SQL Instance on regular PCs, which host 1 or More Tables (Table level partitioning) of a very large database.
2) Distributed JOINs on Tables residing on different physical PCs
3) Multiple Machines hosting same table (Fault Tolerance)
4) Single Virtual IP for database to Application Front End.
-----------
I looked at C-JDBC which is an open source middleware that can do some of the things above. I liked it, but it doesn't seem to support Distributed JOINs which means that our application - which requires quite a few tables JOINs - won't be able to achieve Table level partitioning.
Can anyone recommend any clustering middleware which you can recommend?
I'm currently developing an ASP.NET site with SQL Server 2005 Standard and I'd like to ask a question about the future of the database. It needs to have continuity and performance. I'm thinking about doing replication or mirroring for continuity and table partitioning for performance. I admit I've never done any of those before and I'll learn about them but they're not needed at this time. The question is, I'm currently designing the database and do I have to anything for consideration for those things I'm thinking of implementing later? For example, I'm using Identity in my tables but I've heard about identity crisis using replication with identity columns, therefore I'm thinking of using Guid's but now I fear the Guid column index itself will be the slowdown factor in the first place.
Any suggestions to consider? I'd appreciate any opinions.
Hi, My application is about to scale up significantly, and it seems that SSB could be very useful to help me scale it right, especially I like the multiple readers feature.
So, here's the deal €“ my application is about to get lots of records (peaks could gets up to €“ 300k records per hour). Each record must be processed separately, but could be processed in parallel €“ no dependency between rows (gut feeling tells me not to overuse parallelism, but I€™ll do my tests). It takes about 10ms-15ms to process a single row; I don't mind sliding to non peak hours if needed. Each record is constructed of about 10 columns.
My questions:
1. Is SSB the right solution as a buffer queue? any famous use case is similar to my problem ?
2. What is the fastest easiest way to serialize / deserialize each record?
I would prefer not using CLR integration due to performance issues and stick with tsql for now. I don€™t necessarily prefer XML serialization. If binary serialization works faster, it€™s fine with me.
I have a pivot chart that displays 3 data series.Series 1 values range from 17 to 106.Series 2 values range from 1 to 18.Series 3 values range from 0 to 1.When I display all three series on the chart, the value axis labels run from1 to 120 with major unit lines at intervals of 20.When I remove Series 1, the chart automatically adjusts itself and thevalue axis labels run from 1 to 20 with lines at intervals of 2, thusnicely accommodating the value ranges of Series 1 and Series 2.All this is fine. But when I remove Series 2, leaving only Series 3,the labels run from 1 to 1.2 with interval spacing of .2. Since thesevalues are counts, it makes little sense to show decimal values.Can anyone provide advice on how to keep these axis labels fromshowing decimal values, if a user removes Series 1 and Series 2?Thanks.- Bob
Read only transacted replication to about 60 clients. 100 or so transactions a day (8 hours), transaction (record) is probably about 8K/transaction. Reliable connection over 100base-T. Latency - 15 minutes would be great.
This doable? -- I couldn't find a timing/ sizing model any place.
We use timed subscriptions to do almost all of our reporting. Reports are delivered (primarily via e-mail and printer) once they are completed and users don't have to "watch the pot boil" so to speak.
Apparently SSRS has some load balancing capability whereby it lets only a limited number of threads/reports run concurrently. We often reach this max and lock ourselves up on some very long-running reports, causing other important reports to wait a long time.
We've added some operational reports (ie. document prints) to the mix. These reports run off of OLTP data. They are very fast and very high priority. Waiting on them is not an option. Is there some way we can get SSRS to work on these operational reports in preference to other types of reports (eg. "just for kicks" reports)? I think we'd almost like to add another SSRS server and dedicate it to the operational reports. Ideally the new SSRS server would use the same Report Server database but would only work on subscriptions for certain documents.
Has anybody else tried to solve this problem? This MS document does really address subscriptions or load balancing by report: http://www.microsoft.com/technet/prodtechnol/sql/2005/pspsqlrs.mspx
I've a report projects where each report has a number of columns and the spec is to have all the columns print-out on the same page. Is there a setting that will auto-scale these columns to fit to the page or will I have to edit the font size and widths manually on each report to fit to the page?
When I installed VS 2005, it installed the default version of SQL Server 2005 Express that ships with Visual Studio 2005 installer media.
How can apply SQL Server 2005 Express SP1 to update this existing instance?
Currently, if I run this query:
SELECT @@version
I get the following:
Microsoft SQL Server 2005 - 9.00.1399.06 (Intel X86) Oct 14 2005 00:33:37 Copyright (c) 1988-2005 Microsoft Corporation Express Edition on Windows NT 5.1 (Build 2600: Service Pack 2)
After applying SP1, I should get 9.00.2047.00.
Should I just go to this link and download & install the SQL Server 2005 Express Edition SP1:
I installed Visual Studio 2005 Professional then after that was installed and running, I tried to install the the SQL Server 2005 Developer's Edition which installed but I do not get the SQL Server 2005 Studio Manager. I have remove and reinstalled but it never gets installed. Any ideas?
We have been using Sql Server 2005 Compact Edition 3.1 RDA synchronization method successfully on Sql Server 2000 database. Recently we moved the database to Sql Server 2005, sync doesn't work anymore, it just hangs on one table. On further investigation, we found out that it's the index on that table that causes this. We removed the index, it works fine. We are wondering the root cause, removing the index is not a solution for us. Any thoughts?. Thanks.
(1) I have already installed of SQL Server 2005 Developer Edition first.
(1) Can I install visual studio 2008 without the 2005 express edition of SQL server? Will be any problems because I don't have express edition of SQL server? Do I need to install the express edition of SQL server as well?
(3) How to use SQL Server 2005 Developer Edition instance on visual studio 2008?
I am trying to install SQL 2005 in a 2-node virtual Windows 2003 cluster. I set the cluster up through Virtual Server 2005 with 2 virtual nodes and one virtual domain.

I have a SQL Server 2005 evaluation that has already been installed and setup on a server. I believe it originally had a 180 day eval. There have been numerous databases and users added as well as maintenance plan created...
The eval was put on the machine as an interim solution while waiting for paper work and order processiing things to happen. All the paperwork and ordering... have been completed and I now have the real SQL Server 2005 Standard Edition license key ....
I am very new to SQL Server and need to determine ...
1. Can I update the eval copy to become permanently licensed?
2. Would I want to upgrade the eval to permanent? Will I lose any capabilities by keeping the current eval setup?
If it is reasonable to keep the eval setup
3. How do I go about entering the license key to make it permanent?
If it is necessary to install the new Standard Edition...
4. How do I install it while maintaining the already defined databases, data, users, maintenance plan...

Hello,If I backup and restore an express database to sql server 2005 standard, will there still be limitations in regards to the database size, cpu...etc.? Thanks,Jon
Do you now, How can I move database with datas to release version of sql server? Procedores backup/restore can't help becouse of unsuported version database.
How do I upgrade Sql Server 2005 Express to SP2 if I also have SQL Server 2005 Enterprise SP2 already on the same box? I installed Sql Server 2005 Enterprise first, then applied SP2, then installed Visual Studio 2008 (which installed SQL Server 2005 Express).
When I try to upgrade Sql Server 2005 Express to SP2 using the special Express edition of SP2, I get an error message that says "None of the selected features can be installed". I end up having to cancel the install of SP2.
I'm left with SQL Server 2005 at level 9.0.3054 and SQL Server 2005 Express at 9.0.3042. How can I bring SQL Server Express 2005 to the same level as SQL Server 2005 Entperprise?
Hello!! How can I upgrade from SQL Server 2005 Express Edition to SQL Server 2005 Enterprise Edition? I see allot of example of upgrading from SQL Server 2000 to SQL Server 2005, but no example on upgrading from SQL Server 2005 Express to SQL Server 2005 Enterprise or Standard. Is this possible?
I need to install SQL Server 2005 Standard Edition on a new Windows Server 2003 machine that has SQL Server 2005 Express Edition installed by a backup application (Backup Exec). Will I need to uninstall the express edition in order to install the standard edition? Can the two coexist as separate instances or will the standard edition installation simply upgrade the express installation?
I'm really new to the whole database deal (as well as VB.net) - specifically with the capabilities surrounding VB and SQL Server 2005. My question is open to any recommendations...
What I have is an application that a user uses to create 'new' products. They are presented a form to enter the information regarding the product they wish to create. They enter the details of the product and also locate an image that represents the product, too. Currently, this application saves the product information (including binary image data) into a SQL Server 2005 Express Edition database. This application and database reside on a client pc. What I need to do is to be able save updated and newly created product data into a file of some sort. That file will make its way to a memory stick (USB) and then be transported to a 'field' machine. Quite simply, what is the best way to do this? Are there walk-throughs on this sort of thing? The target database is also SQL Server 2005. I thought I'd post this question on here to get the best design ideas... Any help would be greatly appreciated.
I first tried installing the DVD and of course it told me I must use the command prompt installation method to include the line SKUUPGRADE=1. I found good references to this in the following links:
My servername is URHCS63 and my instance is SQL2005DSS.
When I execute this command, a installation dialog box opens briefly and then disappears and nothing else happens. Here are the results of the bootstrap log file:
Microsoft SQL Server 2005 9.00.3042.00 ============================== OS Version : Microsoft Windows Server 2003 family, Enterprise Edition Service Pack 1 (Build 3790) Time : Thu Oct 25 16:17:48 2007
URHCS63 : To change an existing instance of Microsoft SQL Server 2005 to a different edition of SQL Server 2005, you must run SQL Server 2005 Setup from the command prompt and include the SKUUPGRADE=1 parameter. SQL Server Setup was interrupted. For more information, review the Setup log file in %ProgramFiles%Microsoft SQL Server90Setup BootstrapLOGSummary.txt.
Hi all, I just installed my VS 2005 Pro (full installation) and it installed Sql Server Express 2005. I also have a CD for Sql Server 2005 Developer Edition which I have not installed yet. My need for Sql Server on my development machine is for building and testing apps - just myself - no users will be hitting my sql server on my PC. Most of the time I hit my web server's sql server but also want the engine on my PC for when I'm offline. Question: Should I install the developer edition and remove sql server express? Doesn't the developer edition more closely emulate the full-blown sql server, just that it only allows one or a few users to hit for development and testing purposes? At the same time, sql server express is scalled back in that it doesn't have all the goodies? Thanks! Stewart
Hi, My objective is using a single DB file (mdf file) + SQL Server Express 2005 to run my program I got two softwares here, Visual Studio 2005 and SQL Server 2005. Firstly, I installed Visual Studio 2005, normally the SQL Server 2005 Express Edition will be installed with this software. After finishing the installation. I opened a new project and try to open a DB file (.mdf) from Visual Studio 2005, it works. The problem is that I can't restore the mdf file from an old database file since it lose a lot of functions that appear in SQL Server 2000 / SQL Server 2005. And it is too troublesome and inconvenient to edit a DB file in Visual Stuio 2005. Therefore, I have to install SQL Server 2005 for me to edit the mdf file, so that I can modify, backup, or even restore the mdf file with another DB file. After the installation of SQL Server 2005, I got a tool, SQL Server Managment Studio, to edit the mdf file. I can open the mdf file but when I double-clicked on the mdf file in Visual Studio 2005, it gives me the following error message: Connections to SQL Server files (*.mdf) require SQL Server Express 2005 to function properly. Please verify the installation of the component or download from the URL: http://go.microsoft.com/fwlink/?LinkId=49251 It seems the SQL Server 2005 modify some of the files in SQL Server 2005 Express Edition. Is that SQL Server 2005 and SQL Server 2005 Express Edition cannot be exist at the same time? The issue is I'm working on my computer, but I dun want to install SQL Server 2005 in the server that I will transfer to. It will be much like using Access DB file, without the Microsoft Access software, the program can still work well. However, when I'm still in programming stage, I do hope to have a DB file as the source file for my program, but I can do some editing works with SQL Server 2005. Does anyone can give me a suggestion? Thanks for your kindly reply. Calvin
I am interested in installing both SQL Server 2005 Express and SQL Server2005 b2 on the same machine. Can they both be installed on the same machinewithout conflicts? As in two different instances?John Dalberg
I recently upgraded to SQL Server 2005. My databases are stable and functioning perfectly. However, these databases are using the 32-bit version of SQL Server. The servers are going to be upgraded to 64-bit processors and new Server 2003 64-bit OS's.
Everything I have been able to find says that it is a simple process of backing up the databases in the 32-bit environment and restoring them in the 64-bit environment.
Could it really be that easy? I am looking for someone who has done this to provide any "heads up" commentary on what to look out for during that process. Can anyone provide some information on this process?
Recently I have upgraded my system to SQL Server 2005 SP2 version 9.00.3054; I have developed my packages on SQL Server 2005 SP1 version 9.00.2047. I am unable to open all these packages on SQL Serever SP2 version 9.00.3054 it is giving me error.
Error: Error loading Package.dtsx cannot create an instance of the XML Document Object Model. MSXML may not be registered.
We recently migrated our 32bit instance of SQL Server 2005 SP2 to a 64bit instance of SQL Server 2005 SP2. The migration was performed by copying all .mdf and .ldf files (including master, tempdb, etc...).
Everything seems to have worked nearly flawlessly except for a few glitches seeming to relate to the master database. I am hoping there is a way to mitigate these issues without reinstalling and performing the migration again.
First, when attempting to view the Activity Monitork, I get the error:
TITLE: Microsoft SQL Server Management Studio
Cannot show requested dialog.
Unable to execute requested command.
Unable to launch Activity Monitor. You may not have sufficient permissions. (ActivityMonitor)
View or function 'master.sys.dm_exec_sessions' has more column names specified than columns defined. (Microsoft SQL Server, Error: 4502)
Second, the procedure: master.dbo.sp_procedure_params_rowset fails because of the line: option (OPTIMIZE CORRELATED UNION ALL).
Like I said, I know this is probably an issue arising from copying the master database, but if it is at all possible to avoid another migration, I want to.

If i have been using sql server 2005 express for developing my application and i decide to upgrade to sql server 2005 express with advanced services while still working on the same application, what will happen to my application's database. Can i be able to continue with my work with out any major regrets.
