Thank you.

Answer 1

yes thank you.
following worked :
From your link :
Option 1:Connect to the auxiliary instance using OS authentication (as /) and use password file authentication for target database and connect via Listener.For an example:
Here from auxiliary destination I issued the command and hence successfully connected.
bash-3.00$ rman target sys/a@neptune:1522/dbase AUXILIARY /
Great.
