Re: Shared File System Master Slave

The documentation you linked to is for the AMQ message store, not the KahaDB message store. So if you're using KahaDB as you say, then the page you linked to is irrelevant. KahaDB behaves as I described. You only risk losing messages that have not yet been accepted (i.e. you don't risk losing
