RE: Reducing the number of databases

Additional money might be saved by having only one database which would assume the role of QA, development and
production. That would mean that developers test in production and their own QA. You can save a bundle on oracle
licenses that way. In addition to that, if you switch to noarchivelog mode, you can save a small fortune on the backup tapes. Smart thing to do in that situation would be to put your resume online before stuff hits the fan.

Here we have 3 environments for most applications (dev, QA and prod) and all
Oracle version are the same (8173 now). It works fine. And to save Oracle
license costs, we also consolidated some db servers by putting multiple
instances on one server machine. No problem so far.

I have seen more requirement for individual development databases ( where
ind schema is not possible ) due to complexity of application . Developers
step on each other if they work of same database . A pl/sql developer is
invalidating procedure while a java developer is trying to make his program
work.

Hi,
 
We have around 120 databases. Most applications have 5 environments (dev,
test, integrated test, acceptance, prod) some applications have more. The
applications are a mix of home developped and bought application


(peoplesoft, harvest, compass,...)

New applications are coming in.
New databases will appear soon with DB2UDB.
 
All servers are unix/aix, there are 15 production server and around 10
servers for the dev, test, integrated test and  acceptance databases.
All databases are at 8172 except 6-7 databases and planning to go to 9i in
2004. Off course we see the migration like a pain.
 
We want to reduce the number of databases and instances.
To obtain a significative gain I think we must reduced to around 60
databases.
 
Anybody has done the task to consolidate on less servers and les databases ?
 
One way to do it would be to go with 
    2 instances of dev
    2 instances of test
    2 instances of integrated test
    2 instances of acceptance
    all prod instances are standalone.
 
Food for thought
    backup
    Oracle version
    availability
    naming convention of objects
    security
    ...
 
All feedback is welcome.
