CFMX 6.2 Yeah.... our OPs team says "It is too hard to set up" I wish I could say it is "too hard to code" and get away with it. That is what I suggested as well as clustering the jrun servers two physical boxes, and cfmx server instances for failover. My manager just wanted to be sure I look at all possiblities prior to him "Going to bat" for this solution.
