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. - Vitaliy -- //www.freelists.org/webpage/oracle-l
