Re: Copying Oracle software between Unix servers

Why only interested in the "bad" stories?  The concept of creating a 
Known Good "master" install (using OUI in the case of Oracle) and then 
pushing it out is a common, successful technique for many commercial 
software products, and can work out well for Oracle too.

The 10g version of OUI has a few new features that try to address this 
problem (maintaining known good multiple installs), but it still comes 
up short.

Here are a few hints:

1) don't use tar, use rsync -- this allows you to determine the parts 
that are copied identically and those that remain unique on each server. 
(Plus instead of copying each byte three times using tar, you only copy 
it once using rsync, and only the bytes that need to be copied, not all 
of them).

1-a) don't include the inventory in your copy (which is typically 
outside of the ORACLE_HOME anyway)

2) RAC is a special case, since you are installing the cluster, not an 
individual machine (in other words, there's not a "master" installation 
available to copy).
