I have an oracle 9i database which front-end is c#.net. It was working fine until I created another database.?

Running the c#.NET gives error: Ora-01017: invalid username/password;logon denied. The program was working well before I created a second database.

Try to connect to both databases with sqlplus or some other utility to check if everything is OK with the listener discovering both of your database.


If everything is OK than maybe your program is trying to connect the wrong database.


You don't say if your second database is also oracle9i if this is not true than you must check documentation for compatibility problems.
