When I want to start dbca on my installation I get Java errors below:

System is a RH 2.1 AS.


$ dbca

I have tried "touch /etc/rac_on" solution mentioned in another thread
on  comp.databases.oracle. dbca uses JRE1.1.8. I have also tried to
use 1.3.1 comes with oracle installation and also latest 1.3.1 JDK.
Error was same.
I think this is a OS network issue, However I can not find anything.
My hostname/IP configuration is set correctly.
Anybody have an idea?

Hi Oguz,



I'm seeing exactly the same problem on a Solaris machine running Oracle
9.2.0.1.  Did you find a solution to this?  Thanks,



Rob.
