1: Oracle 10g

Greetings,

Has anyone installed OpenACS on Oracle 10g?

I ask because Oracle has made RAC available on 10g Standard Edition.  As of version 10g RAC no longer requires Enterprise edition, thus it is almost affordable for me.

Anyone here have experience with RAC?  My understanding is that it gets you redundancy, but not a lot of load balancing, and that things work best if you have tuned your application for a RAC configuration.

To followup to my own post, Oracle has a new whitepaper describing the differences between the 4 (!) editions of the 10g database product:

The two most exciting things about this to me are (1) RAC is now part of Standard Edition, and (2) Standard Edition now supports functional indexes.  I haven't dug into the technical details of that yet, but there is the potential for some huge performance increases there, especially creating indexes on things like 'lower(first_names)', 'lower(last_name)', and 'lower(email)'...

FYI, function-based indexes are in Standard Edition from 9i onwards (with 8i they were only in Enterprise Edition).

And functional indexes have been in Postgres, Free Edition, for a long time :)
