The problem is not the TNS file  in PLSQL Developer  if you don t have the oracle installation  you need to provide the location of the OCI DLL file    In PLSQL DEV app go to Tools-Preferences-Oracle connections-OCI Library   In my case I put the next address C  Oracle InstantClient-win32-11 2 0 1 0 oci dll   If have Weblogic app installed  I didnt tried but if you want try to put the next location  C  Oracle Middleware wlserver 10 3 server adr

I am facing to this problem so many times till I have 32bit PL SQL Developer and 64bit Oracle DB or Oracle Client   The solution is    install a 32bit client  set PLSQL DEV-Tools-Preferencies-Oracle Home to new 32bit client Home set PLSQL DEV-Tools-Preferencies-OCI to new 32 bit home  bin oci dll For example  c  app admin product 11 2 0 client 1 BIN oci dll  Save and restart PLSQL DEV    Edit or create a TNSNAMES ORA file in c  app admin product 11 2 0 client 1 NETWORK admin folder like mentioned above   Try with TNSPING in console like     C  tnsping ORCL   If still have problem  set the TNS ADMIN Enviroment properties value pointing to the folder where the TNSNAMES ORA  located   like  c  app admin product 11 2 0 client 1 network admin

I would recommend creating a TNSNAMES ORA file  From your Oracle Client install directory  navigate to NETWORK ADMIN  You may already have a file called TNSNAMES ORA  if so edit it  else create it using your favorite text editor   Next  simply add an entry like this   MYDB      DESCRIPTION        ADDRESS    PROTOCOL   TCP  HOST   123 45 67 89  PORT   1521        CONNECT DATA    SID   TEST  SERVER   DEDICATED         You can change MYDB to whatever you like  this is the identifier that applications will will use to find the database using the info from TNSNAMES   Finally  login with MYDB as your database in PL SQL Developer  It should automatically find the connection string in the TNSNAMES ORA   If that does not work  hit Help- About then click the icon with an  i  in it in the upper-lefthand corner  The fourth tab is the  TNS Names  tab  check it to confirm that it is loading the proper TNSNAMES ORA file  If it is not  you may have multiple Oracle installations on your computer  and you will need to find the one that is in use

In addition to Richard Cresswells and dpbradleys answer  If you neither want to create a TNS name nor the    123 45 67 89 1521 Test  input works  some configurations wont   you can put   DESCRIPTION    ADDRESS    PROTOCOL   TCP  HOST   123 45 67 89  PORT   1521    CONNECT DATA    SID   TEST  SERVER   DEDICATED       as one line  into the  database  section of the login dialog

In the  database  section of the logon dialog box  enter   hostname domain port database  in your case   123 45 67 89 1521 TEST  - this assumes that you don t want to set up a tnsnames ora file entry for some reason   Also make sure the firewall settings on your server are not blocking port 1521
