PL/SQL Developer Oracle Database Connectivity to access

To access our local Oracle in PL/SQL Developer, we need to add an entry in TNSNAMES.ORA file.


You can find TNSNAMES.ORA file in oracle installed folder.

 Example path:

D:\oraclexe\app\oracle\product\10.1.0\server\NETWORK\ADMIN\TNSNAMES.ORA

Add and entry in the file as follows

 HOST_XE =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.101.1)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = XE)

    )
  )

 If you are facing any problems, just check the following tnsping in command prompt.

TNSPING:

• Ping your ip address as in the following example.

C:\Documents and Settings\test>tnsping 192.168.101.1


Output:
