Some people call this consolidation. With IBM's help I tested 60 10g databases in a 14 node cluster (12 with 5 instances per and 2 servers for hot standby). There were some lessons learned. I think it is all about tools. If 60 databases can fit in 12 servers, I should think that would be better than 60 servers. Might be of interest. http://www.polyserve.com/pdf/VMDB_BC.pdf >>>-----Original Message----- >>>From: oracle-l-bounce@xxxxxxxxxxxxx >>>[mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Roger Xu >>>Sent: Thursday, March 30, 2006 7:18 AM >>>To: Oracle-L@Freelists.
