Hi Friends,
I have installed Oracle 10g in my windows 7 64 bit, here i am able to connect with sql plus successfully using user name : test, password : test, and host string : test but when i am trying to connect in my visual studio 2010 using connection string :

Data Source=test;user id=test;password:test;

but it is not able to connect, it is giving error :

ORA-12154: TNS: could not resolve the connect identifier specified.

Even i tried using Data Source:(Host, port,etc)(coppied from transname.ora file) in this case i am getting error :

ORA-06413: Connection not open.

I have wasted 3-4 days but i am not able to connect, so friend could you please help me.

Thanks
Raviranjan

Solution 1

Did you set Data source for your DB in Data Sources (ODBC) on your machine ? With chosen drivers and DB location path on your pc ?
Start --> Control Panel --> Administrative tools --> Data Sources (ODBC) then you need to add data source with chosen Oracle drivers and name it "test" and put source to your DB on your disk.
Then you can call connection using Data Source in connection string.
