Subject Re: AMQ 4.0.1 - Unrecoverable failure
Date Fri, 08 Sep 2006 09:27:14 GMT

Hi Adrian,

Good news.

I deleted the derby db and then restarted AMQ, expecting my messages to be
gone. However I launched Hermes to view them and they were still there, so I
guess they are stored in the Journal and only the Checkpoints are stored in
the Derby DB.

So I'm back from the brink !!
Thanks,
Steve
