Reducing the number of databases

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.
