Subject Re: High Availability and Network Of Brokers
Date Thu, 08 Feb 2007 17:17:45 GMT

I've read about the shared database (known to be slow) and shared file
system, SAN, (quite expensive HW). But where can I read about replicating
messages. I was under the impression that Brokers currently do *not*
replicate messages under a Network Of Brokers scenario. Only a M-S scenario.

How can I read about this and use it?

Thanks,

Shawn
