Informatica Installation Error: Unable to connect to Database

Sometimes during installation of Informatica 9.0.1, at the Database connecting page, we might encounter an error like below

"The connection failed.Correct the database connection information and test the connection again"

One of the reasons can be due to the insufficient privileges to the User supplied in Database User Id.
To avoid such problems, while creation of a Database user for installation of Repository grant all privileges and Grant CONNECT and RESOURCE using below SQL.

>CREATE USER INFA IDIENTIFIED BY PASSWORD;
>GRANT CONNECT,RESOURCE TO INFA IDENTIFIED BY PASSWORD;
>GRANT ALL PRIVILEGES TO INFA;

    1. Try to create SYSTEM DSN for orcl service with any database user credentials(biaproddb).

      While connection test, you will see exact error which is stopping informatica service to connect to database.

      From there debug and resolve that error, then application(Informatica service) can connect to oracle database.
