How to approach a “Got minus one from a read call” error when connecting to an Amazon RDS Oracle instance

Question

I\'m running Oracle 11GR2 on an Amazon RDS instance. occasionally I get an IO Error: Got minus one from a read call when making a call to DriverManager.ge

Answer 1

in my case, I got the same exception because the user that I configured in the app did not existed in the DB, creating the user and granting needed permissions solved the problem.
