-ignoreDiskWarning

I am in the process in installing Oracle 10gR2 patch 2 with response file. There is no plenty of disk available, but installing a patch does not require as much space as specified by the runInstaller.

when I start in silent mode, I get :

$ ./runInstaller -responseFile /home/oracle/10202.rsp -silent
Starting Oracle Universal Installer...

You may not have enough space on your drive for a successful install. Do you still want to continue?

Where should I answer yes? There is a secret parameter called -ignoreDiskWarning which does the trick. The parameter is not listed in ./runInstaller -help.

So I installed my 10.2.0.1 + patch 10.2.0.2 and still have 500Mb free. It is ok for Oracle Home. Check your diskspace before using this to avoid filesystem full.
