Dimitre,
thanks for your reply. I think I'm missing something. If I remember
correctly OAS (in all honesty it's been about 5 years since I installed
one). You have the three following "tiers".
1. Metadata Repository: This is a database that pretty much holds OID, SSO
and Discoverer info.
2. Infra: SSO, OID, etc. These apps connect directly to the MR Database
3. Middle Tier: disco, forms, reports, etc. They connect to the db and
infra services.
The doc says that it's the MR that cannot change the hostname because there
are a lot of places where the hostname is recorded (config files, tables,
etc) and it would be "technically unfeasible to write a script to update
all these locations".
Cheers
Alan.-
