Hi All, I tried all the options available in google to solve this issue, but none of them seems to be working, could you please help me with this error:

Can you really read that?
Neither can we. I know the editor for this forum has some issues with formatting, but they aren't that bad.
Show us the output of 'lsnrctl status'. And be sure to keep it reasonably formatted.
Your use of "@localhost" in the connect string is very suspicious. I doubt you have an entry in your tnsnames.ora for 'localhost'. These might help your understanding of how the pieces fit together:
