Problem Deploying SQL Express Database To Hosted Environment
Nov 2, 2007
I have a web app that uses two SQL Express databases. One of the databases is the membership database. I am deploying the app to a hosted environment. Here is my connection string:
<add name="Akamojo_APSNETDB" connectionString="Data Source=.SQLExpress; AttachDBFileName=|DataDirectory|Akamojo_ASPNETDB.mdf; Initial Catalog=Akamojo_ASPNETDB; Integrated Security=true; User Instance=true"/>
Here is the error that I get:
Could not open new database 'Akamojo_ASPNETDB'. CREATE DATABASE is aborted.
Cannot attach the file 'e:hostingmemberakamojoTournamentLogApp_DataAkamojo_ASPNETDB.mdf' as database 'Akamojo_ASPNETDB'.
File activation failure. The physical file name "c:inetpubwwwrootTournamentLogApp_DataAkamojo_ASPNETDB_log.LDF" may be incorrect.
The log cannot be rebuilt when the primary file is read-only.
The mdf file is not read only. In the hosted environment the database is on the E drive. In my dev environment the database is on the C drive. From the error message, it appears that when it tries to build the log file it is trying to build it on the C drive in a path that doesn't exist in the hosted environment.
Any help is greatly appreciated.

I'm building a hosted website and I am using SQL 2005.
The DBA for the host has told me that i can not encrypt a symmetric key with a certificate, when using that symmetric key for encryption. As i read that this method provided optimum performance/ security for encrypting columns of data.
The DBA told me i can use a cert or a symmetric key for encryption.
I have searched for comparisons and found a blog entry by Laurentiu Cristofor comparing certs with asymmetric keys. Which leads me to believe that certs and asymm are very different than symmetric keys.
My question is which is the best choice in a hosted environment for column encryption, a cert or symmetric key.
Which is more secure? Does one offer a significant performance (dis)advantage?
TIA

Okay, I've read massive topics on ClickOnce, and embedded database applications, etc, etc.
I need a handful of good suggestions how I can create a deployment package, to get my sql express database onto a SQL Express server.
The database will need to be multi-user, because I am also developing a WinForms application to connect to the SQL Express database.
I'm thinking I need to use some automated scripting features, to generate scripts for the database once I am done (unless you have a better suggestion).
After that, I need to know what to do with those scripts, and how can I create a setup / deployment packages to run those scripts against a SQL Express server.
The other alterntative obviously is to copy my sql express database, and run an attach command. This will work the first time, only because this will have been the first deployment of this database.
Please keep in mind when answering this question, that I will not be embedding the database, and as far as I understand ClickOnce is a feature for use with embedded databases or user instance databases (not sure).

Hi there. I've created a windows forms app that connects to a sql server express database. now that it's working on my box, i need to install the entire solution on the end user's machine.
what's the best way to move the database? I found this article:
http://msdn.microsoft.com/en-us/library/ms165716.aspx
but i'm wondering if anyone can give me some insights based on your own experience.
I'm using ms visual studio 2005 and sql server express 2005.
I'm hoping that all i'll really have to do is copy everything over to the new machine and then edit my connection string in the .exe.config file for my app.
Thanks in advance for your help.

I've written a ClickOnce app that deploys a Sql Server Express data file (.mdf) and log file (.ldf) along with the other application files. SQL Express SP2 is a prerequisite for this app. After the applicaiton installs and starts up it copies these files to a specific folder and attaches them by calling the AttachDatabase() method of a Microsoft.SqlServer.Management.Smo.Server object.
This method works fine using Windows XP, however when I run it on Windows Vista I get the following exception:
Microsoft.SqlServer.Management.Smo.FailedOperationException: Attach database failed for Server 'localhostSQLEXPRESS'. ---> Microsoft.SqlServer.Management.Common.ExecutionFailureException: An exception occurred while executing a Transact-SQL statement or batch. ---> System.Data.SqlClient.SqlException: Unable to open the physical file "C:WashMasterDatabasewasshmaster.mdf". Operating system error 5: "5(Access is denied.)".
This exception occurs when I try to programmatically attach the database.
I've searched through the MSDN forums for a solution and I've only found two suggestions:
1.) Create all database connections using a User Instance.
2.) Create the database (using SQL) in the target folder, rather than copying it over from the deployment folder.
I don't like the idea of using User Instances because my entire data access layer is currently written using Ole and I would rather not rewrite it if I don't have to. I cannot find any way to use User Instances with Ole.
I also don't like the idea of creating the database using SQL because it is fairly large.
Here are my questions:
1.) Can User Instances be used with Ole?
2.) Can I somehow programmatically set the permissions of the copied data and log files so that SQL Express can access them without error?
3.) Is there a better method for doing what I'm trying to do or am I destined to have to either rewrite in data access layer so I can use User Instances or create my large database rather than copy it to the target directory?
Thanks.

Hello,
I would like to deploy a per-machine Express database as part of my VS2005 C# desktop application. The deployment must work with both XP and Vista from the same setup files. I'm not using One-Click installation. I don't want my users to have to configure Express with the Surface Area Configuration tool.
Since the database cannot go in C:Program Files because of Vista ACL issues, I am using COMMONAPPDATACompanyNameAppName as the install path for the database and other user writable application files. In XP this expands to C:Documents and SettingsAll UsersApplication DataCompanyNameAppName and in Vista it is C:ProgramDataCompanyNameAppName. Neither of these paths have write privileges for unprivileged users, so the install program needs to change the write permissions at install time. Right now I am using SetACL ( http://setacl.sourceforge.net/ ), to do that and the install goes fine with write permissions on the companyName folder and it's children for all users.
But I can't connect to the mdf file in my COMMONAPPDATACompanyNameAppName folder. If I am the administrator/installer it works fine, but as an unprivileged user I get different errors, but mostly "Could not login user ...". For debugging, I have also tried installing the database in the "AppFolder" directory (which for my app in both Vista and XP is C:Program FilesCompanyNameAppName) and using "User Instance=true" in the connection string, and the connection is made but (at least on XP) the unprivileged user cannot write to the database because the folder lacks write privileges for that user.
I suppose one thing I could do would be to change the folder/file permissions in the AppFolder, but I am reluctant to do that because I have read that Microsoft does not guarantee that the "Compatibility" feature in Vista for the Program Files directory will be available in future releases/service packs.
So is there a way to do a simple installation/db connection for a per-machine database located in a COMMONAPPDATA path?
Thanks for your help.

Folks.
I just moved my domain to GoDaddy.com. When I run my website locally, everything works fine.
When I ftp it to my server space on GoDaddy.com, I get a "remote connection" error. Does anyone have an example of a connection string I should be using to connect while on the server?
Thanks!

Hi,
How do I insert data that I have collected in a local database onto a table on my online ie hosted database which is on a different server?
At the moment I am just uploading all the data to the hosted DB but this is wasting bandwith as only a small percentage of data is actually selected and used.
I thought that if i used a local DB and then update the table on my hosted DB this would be much more efficient, but I am not sure how to write the SQL code to do this!
Do I do some kind of
INSERT INTO sample_table
SELECT xxx
FROM origanal_table
Or is it more complicated than this?
Thanks

I've tried everything. The CreateUserWizard works fine, but then, I didn't have to connect anything for that. I've tried both SQLServer and MySQL. Connection Strings are correct, everything is correct as far as I can see. I've followed every step many many times. I'm about to go back to the old style and use VB6, because this is just stupid. The error I get is "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)" If anyone could help me out with this I'd really appreciate it.

I have a SQL Server 2005 database hosted by a provider that has about 500 databases on their site. I am running Access2007 on a Windows 7 Home Premium edition.
What I am trying to do is create a new Access2007 application and attach (i.e: Link) to the SQL Server tables. I am using SQL Authentication.
I have done this before where i attached via ODBC to Oracle, but it was on the corporate network - not on a hosted server. When i try to walk thru the Access process, it does not seem to let me give it the database name. I have the connection string i use in C# (for example: Data Source, Initial Catalog, UserID and Password), how to connect with Access2007.

Hello,
I am working on an ASP.NET apllication which will work with sensitve data that needs stored as encrypted. The ASP.NET application and SQL Server 2005 will be hosted outside of our company.
My questions are:
When I create a database master key, a certificate and a symetric key to encrypt and decrypt my data, will I be able to use these (master key, cert and symetric key) in other databases (say my local development SQL Server 2005 instance)?
Is a managed hosting a better solution to have total control over the the keys in the database?
Is there a white paper or guidance document for security in hosted databases?Thanks

Hello,
I would like to know whether is it possible to administer a database on a hosted site - i.e inserting some lines, executing a query. I normally access the files via ftp connection. And so far the only way I figured I can mess around with the database is to download it and change it on my desktop PC.
Thank You.

What is the best way to insert records into an SQL Server 2005 database that's being hosted with my website. The data will originate from customer sites as transactions. Do I connect to the hosted database using TCP/IP or do I create web pages that accept the data variables? This is all new to me!
I need this to happen unattended and 24/7/365

Hi allWe have a small database that we host on our own local server. In order toget the information into the database I have a VB program that collates theinformation from a variety of sources and then over our local internalnetwork writes it to the database tables.This information is then made available over the internet using thecompanies broadband connection. In order to alleviate bandwidth issues weare looking at paying for someone else to host the database.What I am hoping to achieve is to keep the VB software, but during the nightupload the data to the remotely hosted SQL server using say a series ofupdate statements. Does anyone know if this is possible, and will SQL Serverlook after the integratory of the data. Is there any issues with therelatively low speed of then Internet as compared with a local networkenvironment. The amount of data we are looking at moving is very little,some where in the region of a few hundred records per night split over about10 tables.many thanksAndy

I'm not sure this is the exact forum in which to ask this question, so if there is a more appropriate forum, please point me in that direction.
Basically I'm looking for advice and best practices for dealing with an upgrade plan for a hosted database. Here is the situation:
- Hosted software application (.Net)
- Uses SQL Server 2005
- When we upgrade the software application to a new version, there will be schema and data changes that need to be applied to the database
- For the software application, we have considered upgrading an offline machine and then switching old one instantaneously.
- For the database, I'm trying to figure out if we can keep everything live for upgrades, or if we should have a small amount of scheduled downtime to upgrade.
So we have identified 2 basic directions:
1) Keep the database live and apply the new script changes just after the application software is upgraded. This means zero downtime, but we'd have to design and test our application to be backward compatible, so that the new version of the application code could handle both the new schema design, and the old schema design. It seems that this option would add a huge amount of complexity because we would essentially be testing a 3rd app/schema combination.
2) Take a small amount of scheduled downtime and upgrade the application code and database all at once.
Obviously option #2 is the most desirable from a development process point of view, and #1 is the most desirable option from a business point of view (zero downtime).
So, I'm looking for some advice on this. Do most people take the whole system down? Are there 100% live systems that deal with this? Are there other approaches I'm not considering?
Any information would be greatly appreciated. Thanks.

Novice SQL Express User...
Now that I've installed SQL 2005 Express Advanced, shouldn't there be a DB Environment I can work with? There must be a configuration mistake because I can't see the "container?" Prior to SP1 I had SQL 2005 Express installed and I could open and use SQL; however, once I loaded SP1 that stopped. I thought if I load the "Advanced" I would be "back in business."
Thanks,
Tony

Hi everybody,
Currently we have a MIS application, developed in VB 6.0 - SQL Server 2000 platform, which is used by around 60 users in our office.
We are planning to host a website remotely, which would allow clients to place orders, track order status etc. on it.
Would it be possible to access our local SQL database from the remote website?

I have a small ASP.Net application developed in VS 2005 that I would like to deploy with SQL Express.
I have included the MDF file in the Application and added SQL Express as a pre-requisite for the Setup and Deployment project.
It installs SQL Express but when it tries to connect I receive:
"This is not a valid login Cannot open user default database. Login failed. Login failed for user 'NT AUTHORITYSYSTEM'."
I don't seem to have any options using the "prerequisite options in VS 2005 in terms of command line deployment parameters.
Likewise I would prefer to attach the database to the instance (because I need to write a connection string from a PDA using RDA and I have zero clue how to do RDA directly back to the file).
Thanks for any help!

I'd like to allow students in a lab to use the Express Manager and T-SQL to create their own databases. I think I've figured out just about everything - but the last step. Here's my thinking on how to do this:
1. Students are power users, not local admin
2. Created a login for the builtinpower users group as follows:
create login [BUILTINPower Users] from windows with default_database=[master]
go
exec master..sp_addsrvrolemember @loginame = N'BUILTINPower Users', @rolename = N'dbcreator'
go
3. Now students can start the Express Manager and connect to:
localhostsqlexpress using Windows Authentication
4. After they do, they can open and run a script creating a database and populating it with tables and records.
5. All good up to here... but when trying to access the new database using VB Express (file based, not a remote connection) access is denied.
The problem is in the NTFS file permissions being assigned to the new database mdf and ldf files. Local administrators and the builtin Network Service accounts have permissions, but the student who created the database gets nothing... So the student is denied access to the mdf and ldf files when trying to make a connection to them using VB Express.
I can go in with a different account having admin privileges are assign privileges to power users for the mdf/ldf files after they're created but this isn't what I need (students need to work whenever they want without waiting for an admin to fix the file permissions).
Maybe I'm going about this all wrong? If I have to I can insist on students always using VS 2005 instead of VB Express and use connections to a remote database (no problems doing this), but I'm still hoping for an express solution.
I'm new to this forum, so apologies if this is a dumb question (but even if it is - can anyone point me in the right direction?)
Thanks

Hello all,
I hope someone can help with my current issue as i have now spent the last 8
hours trying to solve it! Here goes...
I am currently moving all my websites from our in house set up to a FASTHOSTS
dedicated server. Our in house set up consists of separate server for web
and data and works well even with my recent foray into .Net sites.
I have just moved the most recent of my .Net sites
(http://www.alfadealerads.co.uk/home.aspx) to the FASTHOSTS server and cannot
get the site to connect to the database (this has also been installed on the
FASTHOSTS server). One of the pages that connects to the DB is
http://www.alfadealerads.co.uk/links.aspx, where i am getting the error..
System.Data.SqlClient.SqlException: Cannot open database requested in login
'MasseratiChauffeurDrive'. Login fails.
Login failed for user 'lateral'.
This DB has been restored from back up from the original DB. I have
recreated the user name on the new SQL server and added it to the new DB
also. I am using a webconfig to connect to the DB, the exact same one
that works on my current live server
(http://www.maseratichauffeurdrive.com/home.aspx) only with the obvious change
to the SQL server name.
The only difference i can see in the 2 setups is that the new one has both the
webserver and the SQL server on the one machine and that machine uses domains.
My current in house setup does not use domains and as mentioned before web and
date are 2 separate servers.
Can anyone help? Or even understand what the hell i have written? lol
Thanks in advance
