Question about running . /runInstaller

[learn]

I realised that you can run

. /runInstaller

from either the $ORACLE_HOME/bin
and also from the location of the oracle software on CD or the directory where the software is downloaded and unzipeed.

What is the difference between these 2 ways of running

. /runInstaller

[davey23uk]

if its the same version of the software then nothing - runInstaller in $ORACLE_HOME/bin is usually a soft link to oui/install or something like that.

The only difference is when you have a cd for a newer version.

If they are the same, the disk one will be quicker as reading from disk is usually quicker than reading from a cd
