Yes and no.
Yes, because the DBStore has automatic crash detection and damage repair at startup time built in. BTW., "damage" sounds
more severe than it probably is. All damage that can happen is related to some internal counters that *optimize* the
startup time; i.e., only information that can be recomputed from the "safe parts" of the overall data can be lost after
ungraceful shutdown. Information such as the last ID that was assigned to an object.
No, because I agree it would be great to be able to perform a clean shutdown when the service stops, but I'm not sure
how that could be done. I suspect it depends on the concrete service wrapper. I'm not very familiar with the different
technologies that are available, nor with what that would mean for CDO. Are you?

Unfortunately I'm not. It would be great if others could share their expertise on service wrappers...

Hi Greg,
I quickly searched the web and found http://yajsw.sourceforge.net/ , which I think looks quite promising. Are you
interested in evaluating it and, in case it's a good match, discussing your findings in a new bugzilla?
Cheers
