Installing EBS 11i (11.5.10.2)

Question

Hi All,
I have installed EBS 11i before many times , and each time I install in another server (linux) i encounter different error.
My error now is that the gui window installer just closed suddenly without completing.
I tried to restart it many times (./rapidwiz -restart ) but still the screen window will just close out.
I check the log files and I can see that the installer passed the DB Tier creation. I can start/shutdown the database and the listener. But the application tier has not yet been populated. There is no data yet in the respective directories (prodcomn,prodora,prodappl)
The following is the log file of rapidwiz -restart (last part)

Thanks for your words, it is really too much. Thanks anyway :)
Did you verify that the database was created successfully? From the entries above, it indicates that the JDBC connection cannot be established, and this would happen if there is a missing entry in the hosts file OR the database is down OR the database listener is down. So, please refer to the installation log file and/or alert_<SID>.log file to verify this.
