RE: Reducing the number of databases

Unfortunately, that's what we have!!!!! And yes, my resume is on-line!!!! Our database configuration and installation was outsourced and so was the installation of our ERP. So guess what happened? No consultation with the "support analyst" and now they want to split the schemas into multiple instances. Go figure :-)

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.

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.

Sent: Friday, September 19, 2003 12:50 PM To: Multiple recipients of list ORACLE-L 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.  



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

    Oracle version
    naming convention of objects

All feedback is welcome.
