Networking And Gateways :: ORA-12154 - Could Not Resolve Connect Identifier Specified

I have oracle 10g and Developer suite installed locally in my system and I have edited my TNSNAMES.ora file and added a entry for VISLINUX(for both Developer suite and oracle DB TNSNAMES.ora files).

When I use TNSPING comand I get an error for the schemas APPDEV and VISLINUX.
