Unable to connect to Guest OS DB from Host OS via SQL Developer

user2526689Apr 13 2015 — edited Apr 28 2015

Hi,

I have installed Oracle Apps R12.2 on Oracle Linux 6.4 in virtualbox, on system running Windows 7 ultimate.

Virtualbox network types are : NAT (10.0.2.x) and Host Only (192.168.56.101)

In the guest OS(Linux 6.4), I can connect to applications via Firefox and DB via SQL developer.

In the Host OS(Windows 7), I can connect to the application vis firefox. But i am not able to connect to the DB via SQL developer.

Port 1521 is added in the firewall of the Guest OS(Linux 6.4).

In the Host OS(Windows 7), ip 192.168.56.101 is added in Hosts file as 192.168.56.101 ebsr12.vbdomain ebsr12

I can ping to 192.168.56.101 and ebsr12 from Host OS(Windows 7). also can connect to 192.168.56.101 via putty.

I am trying as below in SQL Developer in Host OS(Windows 7):

User: apps

password: ******

Host: ebsr12 (also tried ip 192.168.56.101)

Port: 1521

SID: VIS

This gives the error ORA-12547: TNS: lost contact

Please help to resolve this.
