Pete, We're close to your wants, mainly by accident. We purchased reliable servers (HP 9000) and good disk subsystems (EMC Symmetric), a good battery backup UPS with a fast start generator. With that we've got 90% uptime with no unscheduled down time. Scheduled downtime is still a need. We're looking into RAC with 10g to give us the remaining 10% but I'm skeptical. -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Peter Barnett Sent: Thursday, July 07, 2005 9:35 AM To: Oracle-l Subject: High Availability -- True 7x24x365 We have finally moved into the modern digital world. Outages of our company web site are being noticed by our customers which is causing management to ask about maintaining 7x24x365 up time. There are several ideas being circulated but I was wondering how others are doing it? The requirement is true 7x24x365. Patches, upgrades, maintenance need to be transparent to the users of our web sites.
