Will this work with replication too. I see it with a mirror database, but could it work if I was keeping two copies of the database and wanted to transparently reroute the connection to a surviving server?
View 3 RepliesHi there.
I have a database mirroring session running, and both principal and mirror are working fine. But when i unplug the network cable from principal server, creating a failover scenario, the client doesn´t get redirected to the mirror.
I get an error saying: "A transport-level error has ocurred when received results from the server. The specified network name is no longer available."
connection = "Data Source=SISAD;Failover Partner=Projecto-SWS1;Initial Catalog=SIERE;Persist Security Info=True;User ID=sa;Password=testing;Connection Timeout=100";
//this method is called many times by a thread, emulating some request to the server
public static void Inserir(int codAutor)
{
SqlConnection sqlConnection = new SqlConnection(connection);
SqlCommand command = new SqlCommand("insert into Autor values(@codAutor,'test')", sqlConnection);
command.CommandType = CommandType.Text;
command.Parameters.AddWithValue("@codAutor", codAutor.ToString());
command.CommandTimeout = 200;
sqlConnection.Open();
command.ExecuteNonQuery();
sqlConnection.Close();
}
I think the error is because the ExecuteNonQuery() method return info about the rows affected on the server. But in this case how can i create a failover scenario with client-side redirect ?
Thanks in advance.
Hi All,
My apologies if this question seems abit basic, but I'm a DBA by trade and programming .Net isn't my strong point ;)
I've enabled database mirroring on 3 SQL 2005 servers, a principal, a mirror and a witness.
Principal - SQL 2005 Enterprise Edition, SP1
Mirror - SQL 2005 Enterprise Edition, SP1
Witness - SQL 2005 Express, SP1
I've written some test code to test the mirroring but as soon as the connection is pulled from the principal, the client re-direct doesn't work and the program bombs. I'd be grateful fi someone could have a look at my code below and tell me if there's any schoolboy errors??
(NB, the user running the code is a sys admin on all 3 servers)
Thanks in advance.

Hi there.
With Client-Side Redirect, connections can be dinamically redirected in case of failover. But if a long transaction is running on the principal, when it fails the redirect doesn´t work with the current ado.net connection, connected to the database running that transaction.
So if the principal fails, current running transaction will be lost right ?
Thanks in advance.
I have setup a database mirroring session with witness - MachineA is the principal, MachineB is the mirror, and MachineC is the witness. Each SQL Server instance is hosted on its own machine. The mirroring is working correctly. If I submit data to the database on MachineA, and then unplug the network cable on MachineA, MachineB automatically becomes the principal, and I can see the data that I originally submitted to MachineA on MachineB. All the settings are showing correctly in Management Studio.
My issue is with the SQL Native Client and a front-end application that needs to make use of this database. I have setup my front-end application to use the ODBC client and specified the failover server in both the ODBC setup and the connection string. Here is the connection string that I am using :
Provider=ODBC;Database=master;DSN=MachineA;Failover Partner=MachineB;
Everything works perfectly on my front-end application when MachineA is the principal. If I unplug the network cable on MachineA, MachineB becomes the principal, and the failover occurs correctly on the database side. The problem is that my front-end application is not able to query the database on MachineB.
BUT - if I plug the network cable back in on MachineA (making the database on MachineA the mirror), the front-end application now works and can access the principal database on MachineB. I wrote a quick tester application to verify what I am seeing, and I am convinced that this is what is happening. The mirroring is working perfectly, and everything is setup correctly. The SQL Native Client is setup correctly. The problem is that the automatic failover to MachineB that is built into the SQL Native Client only works if both servers are plugged in.
In this scenario, when I plug both servers in, I know that the front-end app is definitely pulling from MachineB (since the mirror database on MachineA is in recovery mode, it's unavailable, and the front-end app displays the server that it is pulling data from).
Am I using an out-dated SQL Native Client? The version number displayed in the ODBC configuration page is 2005.90.2047.00, and is dated 4/14/2006. Has anyone experienced this issue? I'm guessing that it's a problem in the SQL Native client, since the mirroring really seems to be working correctly.
Thanks,
Bill

Do I need to install SQL Server 2005 Native client drivers on the servers that contain applications that make connections to the new SS2005 db server? My understanding is that this driver is backward compatible with SS 2000... Can I have both installed on the same server, and then create and ODBC driver for either?

I am new to SQL server 2005
Windows 2003 Server and all client PCs are all on the same network. I installed SQL 2005 std version on windows server 2003 and created a database and tables in it.
I have two users, who want to connect to SQL server 2005 from their PCs (they have windows XP):
These are two things that I need to facilitate:
1) They want to be able to write queries using Query Designer and run from their PCs.
2) I created an MS Access database on my PC, I want to use Access database as a front end to the SQL server database. I will create queries, forms in Access DB, and I want to be able to get the data from SQL server Database to do this. I guess I can use ODBC to connect to tables in SQL server database.
3) I want to connect SQL server to Oracle database, and run oracle stored procedures. I want to load the results of oracle stored procedures into SQL server database tables. I guess I will use IIS for this.
Any suggestions are appreciated, especially with item number 1.
I'm trying to remember how to install the SQL 2000 client tools onto a SQL 2005 server. There are a couple of bizarre steps that will allow this to happen, but I can't for the life of me remember what comes after the unicycle down the stairs with the umbrella stand of machetes.
Can anybody remember the magic, or do I resort to using VPC to kludge the install until I can find my clay tablets again?

I'm
having difficulties when connecting to our SQL server 2000 from my SQL
Server Mgmt Studio 2005. I can't create tables and columns due to
permission errors. But from 2000 (on a different machine) it works
fine. *Sometimes* even when I log in with my AD account it won't let me
in and complains that user 'null' is not authorized to log in...
Anyway, I've installed both SP1 and SP2 and the problem still persists.
Any help is appreciated.
P.S>
I tinstalled SQL 2000 on my machine but that didn't help either; I
guess the 2005's configurations are being read by 2000.
When attempting to install SQL Server 2005 SP1, I receive the error, "a recently applied update, KB913090, failed to install." The Installation complete dialog shows the Client Components product Status as "Failure" with the description detail, "Unable to install Windows Installer MSP file". My Operating System is Windows Server 2003 SP1.
Please advise as to risks and fix.

I have recently installed SQL 2005 client tools with SQL Server Management Studio and accessing databases on a SQL 2000 server. The response I am getting is extremely slow. Should I go back to SQL 2000 client or are there methods by which I can improve the performance.

I've installed SQL 2005 Express, enabled local and Remote connections but my client app cannot connect to the SQL server. I'm getting access denied or SQL does not exists. Any idea's on how to resolve this issue?
View 1 Replies View RelatedHello,
I have installed SQL server 2005 enterprise edition on Windows 2003 virtual PC (full installation). The installation went through successfully. However, after install completed, I cannot find any of the client tools under the start menu -> all programs -> Microsoft SQL server 2005 menu. The only item listed under the SQL server 2005 is Configuration Tools, which is used to configure the database server.
I have tried to install the client component again (in case I didn't install them at the first place) but the installation process cannot be started since it detected that the client components have been installed already. I can also see the sql server native client running in the services.
The server engine is working fine since I can connect to that sql server using another machine where I have the client tool (SQL server management studio).
One of my friends has exactly the same problem. He installed the sql server 2005 Standard edition on windows 2003 server (full installation), but the client tools are not showing up in the start menu either.
I also checked the location for the SQL server management studio (Microsoft SQL server/90/Tools/Binn/VSShell/Common7/IDE), there is only one folder called publicAssemblies listed under. Is this correct or something is missing?
Thanks
Hi,
Pls let me know if SQL Server 2005 Management Studio (client tools only) is compatible with Windows Server 2000 or not?

Hello,This is hopefully just a quick question. I'm looking to re-jig our in-house development infrastructure and part of that will be some sort of SQL Server product, and I'm hoping it will be the Developer edition.My question is, how many copies of the Developer edition would I need to purchase, if I have one Windows 2003 server (which will server the databases) and two client machines which will use it.My initial thought is 2 copies, one for each user (as the license states). But what about the server? Do I just install one of the two copies onto the server and the license covers the two client connections?This might seem a silly question with an obvious answer to you guys. However, am I right? I just need to get this clear in my head.Thanks in advance..

Right-clicking "Protocols for MSSQLSERVER" under the Sql 2005 Server Configuration Manager I
find the "Force Encryption" option. Right-clicking the SQL Native Client Configuration, Client Protocols,
I find "Force Protocol Encryption"
I believe these can be used together to force the connection between a client (running the SQLNC client) and a sql 2005 server to be encrypted. In other words, the data "in motion" can be encrypted.
1. Is my understanding correct?
2. Do I need to use a certificate to make this work?
TIA,
