Oracle People,

For Oracle 10gR2 installs,
I'm trying to figure out some of the details behind the
option to runInstaller.

If I run runInstaller with no options,
it will look at various attributes of my Linux OS.

Where might I find a list of the shell commands it is using
to gather information about the target host?

I'm assuming they are shell commands. Perhaps they are Java calls
or an execution of a compiled executable?

Next, I'm curious about what runInstaller does after it gets the
information it wants from the OS.

Obviously it must try to "join" the information with a list of
OS attributes which are stored on the installation cdrom.

If it gets a match, it allows the install to continue.

Where is this list of OS attributes found on the installation cdrom?

Answer from hpuxrac in comp.databases.oracle.server:
Usually you use the ignore on linux if you are using a "slightly"
different version of linux ... aka centos or whitebox or ( ubuntu I
guess ) versus redhat typically.

IE You know that the difference is superficial ( since it is a clone
of red hat usually I think ) and it is little white lie to the

Then the installer will look at specfics os patches ( rpms whatever )
and kernel settings and give you another chance to say "yeah yeah " by
setting the checkbox.

There's a bunch of websites with good oracle/linux install info like
http://www.puschitz.com etc ...
