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.
