I have successfully installed r12.1.1 vision instance erp in my laptop. And its working.
I now want to query back end tables using SQL developer. Both SQL developer and SQL plus are installed with media pack itself.
I now want to configure vision instance into SQL developer.

Also when I opened SQL plus and gave apps\apps it gave me the following error message.
ORA-12650: TNS:PROTOCOL ADAPTER ERROR
