And what does it say about the size of an ORACLE shop? Just one thing -- 300
concurrent users. It doesn't say anything about the:

- AVG number of ACTIVE sessions (v$session.STATUS)?
- daily REDO throughput?
- monthly DATA growth?
- total count of segments?
- total count of objects?
- number of sessions served hourly?
- recovery strategy and how often it's tested?
- number of hosts in PROD?
- number of hosts in TEST/DEV?
- how often TEST/DEV is refreshed with PROD?
- is monitoring deployed? Escalation process?
- number of DBA's SA's?
- is there a central Knowledge Base/SR system?
- where's the hardware? Hosted? COLO? Own DC?

When you figure the cost of operating a decent size shop the initial cost of
hardware is irrelevant.

When a new ORACLE shop is setup people need to look ahead and position
themselves to:

- keep ARCHITECTURE as simple as possible.
- choose as FEW vendors as possible.
- pick the MOST stable OS/HARDWARE.
- get the BEST DBA + SA they can afford.
