DataSource Controls :: Code Behind To Disconnect Temporarily All DB Connections To Backup/copy Database?
Mar 30, 2010
SQL Server Express 2005 MS Visual Studio 2005 Using ASP.NET with VB code behind. Requirements: Click a button on an ASPX page to disconnect temporarily all DB connections when not in use to allow a script to backup/copy the database to a safe backup location. When a user access the db afterwords, the DB connections will be re-established.
If this is imposible, recommend an alternative. Note: I am working with what I have been given and authorized to use.
I have two databases- database1 and database2. I have taken the full backup of database1 and want to restore it to the database2. When I do it in the Sql server Management Studio, I get this error:
The backup set holds a backup of a database other than the existing 'database2' database.
how can I achieve this using the SQLdatasource control? I'm using the VB language. What controls/commands should I use to have a backup and restore function on my website?
I have an SQL 2008 R2 database on an X86 machine that I have backed up a database from. Now I want to restore it to an SQL 2008 R2 instance on an X64 machine and keep gettting format errors (attributed to restoring a higher version of database to a lower database instance ie 2005 to 2008). On inspecting the databases I find the X86 is version 10 and the X64 is version 9 (which is supposed to be the 2005 database)...are there different versions of the same DB for different software platforms?
1. i have created aa database named "qraghul" which contains two tables. i want this database to backup from my system and restore it to the host server or any other system. how i can do it.

copying some data from an existing remote database(SQL2005) to an existing local database.First - I have very little experience in this area. I'm using Visual Web Developer 2008 (VB). Currently if I want to update some data in the local database I do something like this:
Dim conn As Data.SqlClient.SqlConnection = New Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("CCCdbConnectionString").ConnectionString) Dim cmd As Data.SqlClient.SqlCommand = New Data.SqlClient.SqlCommand("UPDATE [Orders] Set [OrderStatus]
I need to make a backup copy of a file on a remote server. The backup will remain in the same directory on that server. The problem I am having is that the file is large and it appears to be copying it back to the server the code is running on and is taking too much time. Is there a way to make a copy of the file in place without it being sent across the network?
I've been playing about for ages in an attempt to get a simple bit of code that can detect whether or not SQL Server is listening remotely or just locally.. My pretty lame attempt so far is as follows:
[Code]....
I'm sure there must be a better way to do this! Aside from the fact that this code fails to work properly.
sp.IPAddresses contains:
- 127.0.0.1 - 0.0.0.0 - 10.0.0.10
When I used Surface Area Manager > Surface Area Configuration for Services and Connections and set Remote Connections to "Local connections only" sp.IPAddresses still contains the same addresses.
My lecturer insists that a web site should NOT have a static SQL connection as its not good practice (didn't explain why) but then I thought that if one makes instances of an SQL connection everytime I want to save, delete or edit then surely thats a bottleneck as I would need to everytime establish a connection and then do the save process. From what I have read online, the process of establishing a connection to the server is the longest (about 5 to 10ms)...
How would one manage their SQL connection. At the moment I do something like:
the SQL connection option ARITHABORT is OFF for OLEDB connections, which I assume Linq To SQL is using. owever I need it to be ON. The reason is that my DB contains some indexed views, and any insert/update/delete operations against tables that are part of an indexed view fail if the connection does not have ARITHABORT ON. Even selects against the indexed view itself fail if the WITH(NOEXPAND) hint is used (which you have to use in SQL Standard Edition to get the performance benefit of the indexed view).Is there somewhere in the data context I can specify I want this option ON? Or somewhere in code I can do it??I have managed a clumsy workaround, but I don't like it .... I have to create a stored procedure for every select/insert/update/delete operation, and in this proc first run SET ARITHABORT ON, then exec another proc which contains the actual select/insert/update/delete. In other words the first proc is just a wrapper for the second. It doesn't work to just put SET ARITHABORT ON above the select/insert/update/delete code.
I want to copy a database on a development server to my local server. I am not the server administrator but I have rights to the database. Soon after the wizard Executes the SQL Server Agent Job it fails and the error message says:
The job failed. Check the event log on the destination server for details.
Where do I find this log? Also what could be the problem?

We have developed web application using Asp.net, C# and SQL Server. However, When viewing the Process Info Tool for MS SQL Server, we see lots of processes (150-1000+) with Status = 'sleeping' and Command = 'AWAITING COMMAND' (Application = '.Net SqlClient Data Provider')The DataReaders and Connections are all being closed, but still the sleeping connections are accumulating. The problem becomes so severe that we finally get a "General Network Error" or a "Internal system error" and if we restart IIS. We have tested a lot but no success.
I'm working in ASP.NET 4.0, and I've got a large web form which represents a single business entity. A user can upload multiple images associated with the entity. The entity is created and assigned a GUID upon submitting the form. The files will be stored to a file system.
The problem is that we have to name the files after the GUID that is assigned to the entity after it is inserted to the database. So before the submit button is clicked, we will have several image files floating around in limbo.
There are obvious answers to this question -- you save the images to the file system and then when the business entity is created, you rename those files. However, I believe that there must be very strong patterns and several key details that would make for a very robust system. What's best practice for this scenario?
