will be the same as:

Code:
export TWO_TASK=remote_db
$ORACLE_HOME/bin/sqlplus scott/tiger

So if i entered the command
Code:
$ORACLE_HOME/bin/sqlplus scott/tiger

the value of TWO_TASK is identified and it will match the same in the tnsentry(tnsnames.oa file)and fetches the host name and port and then establish a connection to it.Correct me if am wrong.
My intention is to understand the flow of establishing the db connection.
