1016493Jun 21 2013 — edited Jun 25 2013

Hello,

I have started the database 11g XE on Centos 6.2 . I can connect using the installed Run SQL command prompt (using system userid and password). When i try the same using SQL developer i get this Network adapter error.

Connection type basic

Host name 127.0.0.1/localhost.localdomain/actual Virtual box IP

SID XE

Username System

Password works with run sql command prompt

Entry in tns.ora is

XE =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = XE)

    )

  )

Help please

regards

Sameer
