In on server, there are 3 oracle application server with each TNSnames.ora under separate directory at D driver. I installed pl/sql developer in C driver.
I could log into different remote (include a local orcl test DB at D driver) database from these tool include sqlplus. But I could not log into any ( include a local orcl test DB at D driver) database from pl/sql developer. Plz see attached pict. I also do not find a place of pl/sql developer TNS configuration.
Where do I need to configure pl/sql TNS file? my OS is 32 bit window 2003 Sp2. database version is 32 bit or 64 bit 10.2.0.4 Please advised me.
