Article Type: General
Product: Aleph
Product Version: 20

Description:
I'm planning to load a test version of Aleph 20 on our current Aleph 18 test server, with the plan to run both versions simultaneously for a while. Is there any documentation which you would suggest I read prior to doing this? Are there any "gotchas" which you think I should watch for or be aware of while doing this install?

Resolution:
First, I strongly suggest that you get the /20/Installation and System Requirements/Aleph Installation Kit.pdf from the Doc Portal if you have not already done so.

I don't have any direct experience with Aleph installations and can't supply any Gotcha's. You might want to check the Knowledge Base.

I do have an example of a server which has the *exact* structure you describe: our aleph112 server where both v18 and v20 are installed. (This is the server that I used for the Upgrading to v20: Upgrade Express Webinar.) The critical thing, of course, is to keep Oracle 11 completely separate from Oracle 10 and Aleph 18 completely separate from Aleph 20.

I know that you can have different mount points, so you may choose a different set-up. But I will show the directory structure on our aleph112:

aleph@aleph112(a20_2) USM01> cd /
aleph@aleph112(a20_2) USM01> ls
backup/ etc/ home/ mnt/ oradiag_root/ sbin/ usr/

dev/ export/ m1/ opt/ proc/ tmp/

aleph@aleph112(a20_2) USM01> ls
