Hi

I have installed oracle database 11g on my pc and recently installed oracle developer suite 10g
I am unable to connect to my database using oracle developer suite It's giving an error that

"ORA-12154:TNS could not resolve the connect identifier specified"

How to solve this problem or can't we connect to database using older version of suite
Kindly answer me this question as soon as possible

Are you or have you been able to connect to the database before you installed developer suite? You should know for sure that your DB is up and running and that you can connect. After that, setup the connection in developer suite.

Ok, so I assume you were able to connect using sqlplus, can you show the error (screenshot) that you are getting in developer?
