Oracle connection faster with network connection, slow when in standalone

Hi,

When I conect using sqlplus on the local machine running Oracle it connects to within a sec. However, if I pull out the network cable, and then try and connect, it takes over 20 sec. I have this repeatedly with the same results. Hence it is cumbersome for me to work with the computer in standalone. Where is the problem with the local connection (ie. without network connected?? I have even tried a loopback plug and a switch with only one machine with the same slow results. Only if the machine is part of a bigger network with my internet connection (ie. DNS setup with ISP addresses) does it work fast -- hence it leads me to believe that it has something to do with DNS. I have the machine defined in /etc/hosts as a private network machine, with a gateway and a firewall for external connection. Hence surely from a local perspective this connection should be fast. Is Oracle doing something else in resolving the name, like not looking in /etc/hosts first??

Thanks

Rajen

You have to activate the Loopback adapter and to make it first adapter in the list as explained here:

See

The link provided valuable information  understanding the network/standalone operation of Oracle. However, for now I just remove the DNS setting and Oracle works fine in standalone. However, when I get on to network I add DNS values in again.
