An error occured while connecting to the database: "ORA-12535 :TNS :operation timed out." How do I fix this?
To get past this error, either increase the CONNECT_TIMEOUT parameter in your LISTENER.ORA file or set it to zero, which means to wait indefinitely. You'll have to bounce or reload the listener for the change to take affect.
