Is it possible to rest the Oracle service names of my Oracle databases in VB rather than using the Oracle tools net manager etc?
I have an app that needs to point at different db and I'd not have to switch out of the app and to net manager to do it.

Sparky191,

Are all the database SID's are set up in your TNSNAMES.ORA file ?, if they are then switching between databases from VB is easy - you just change the server name in your connection string, and then re-connect to the new database.

For example, the below will switch an ADO data control between 'database1' and 'database2'

Adodc1.ConnectionString = "Provider=MSDAORA.1;Password=pass;User  ID=user;Data Source=database1;Persist Security Info=True"
Adodc1.Refresh

Adodc1.ConnectionString = "Provider=MSDAORA.1;Password=pass;User ID=user;Data Source=database2;Persist Security Info=True"
Adodc1.Refresh

I should clarify. My VB app will configure the connection for another app that uses the database SID's. So I guess just changing that TNSNAMES.ORA file will be all I need to do.

i recommend u to use ini file for storing the database name, user name and password. so every time u starts the app, ur app will connect to the database defined in the ini file. For doing so u have to retreive the setting from the ini file.

Also u can change the setting of the ini file through VB app.

Hope this will solve ur problem.
