RE: Copying Oracle software between Unix servers

If you're talking about the core Oracle database technology, the software is pretty clean and relocatable. Boring, actually. As long as you manage a few details such as making sure users and groups have the same user and group ids, not much can go wrong other than inadvertantly changing ownership or permissions as you make the copy.

If you're cloing the e-Business suite, Oracle decided to allow creativity in the location of embedded strings that vary from installation to installation, so instead of simply making a tar or cpio preserving permission and ownership bits the cloning process requires significant planning, tool support and effort. The noxious weed of the "C: has everything" culture that spawned the mixing of software and data seems as unavoidable as long mixed case variable identifiers and pagelong listings for individual jobs in a process status listing.

I've done this with 9i installations, so I'd like to hear if there are drawbacks. If you're installations are very consistent, and you are installing the same options from server to server, I think it can work well. AFAIK, a relink all should let you know if there are problems with the installation.

In one sense, if each installation is done via the installer, then testing a patch application on the development environment is not a true test of what you will encounter when you apply the patch on production. Right now, I'm patching servers and every one was done slightly differently; different paths and different options. I've had an easier time 'fixing' Oracle inventories for installations built from cloning than from installations.

If I could be missing a hidden problem, someone please let me know ...
