Why OIF 11G is such a pain in the ass to install (on Windows)?!?
(Updated)

1st attempt
RCU failed without java bridge
Create ASinstance failed

2nd attempt
RCU successful without java bridge ( !? )
OIM installer ran for 1 hour + and hung with no error (step at when restarting domain)

3rd attempt
Windows Virtual memory error prompt before getting "Create ASinstance failed" again

4th Attempt
--- still the same


Let's compare the other federation products installation time
Ping Federate - unzip & run (less than 5 minutes)
Open SSO - deploy j2ee application & run (less than 10 minutes)
SiteMinder FSS - 1-2 hours for full architecture
Novell NAM - 2-4 hours for full architecture
OIF 10G - 1-2 hours just installation
OIF 11G - I've spent few days now...and still nothing solid (never understand why do they have to make it such a heavy weight ...)

N-Attempt
With great help from Oracle Support managed to found the issue to be opmn getting strange results from dns lookups.
So my hostname is not resolving to my IP via DNS although I've override it in the hosts file.
Unrelated to this, also bump into several hostname lookup problems with opmn and the new admin-everything enterprise manager.
So, becareful with your DNS and hostnames!
