When I try to login into a database, I get an error APP FND 01516 Invalid Username, Password or Database. How to solve this problem, can anyone guide me through this?
To work your way around this error, you need to check the log file of the alter database. Once, you reach the end of the file. Look for the error report. There will be some ORA20 errors. If you find these errors, then close the database and application. Now find the init parameter file and open it. Increase the initial values of process and session and save it. Restart the application and database with this new init file and the error will be gone.
This error occurs because the limit of users or authorized access has reached or there is a block from the side of the server. The above solution is for when you have entered the correct Username and Password, and also you are an authorized person to have access, but still, you are unable to access it.
