Jim, I'd appreciate your considered opinion as to the best strategy for achieving (IMHO) the essential goal of clustering, that being "continuity of service". especially in Web Server applications where 24 x 7 uptime (or as near to as humanly possible) is required.

Given the need from time to time to take an individual machine down, clustering, appears to be the logical way to go. I can already achieve that easily with web servers (Linux Virtual Server Project), but database servers are a different matter all together.

kind regards

Gary
