Marc-Philip,

We can't currently take advantage of the Event Dispatcher because we're
only running MaxDB 7.5.  But assuming it's still in there by the time we
upgrade to MaxDB 7.6, we'd love to start using it.

We use HP's Data Protector software to backup our MaxDB databases.  (It
works great, btw.)  We also have AutoLog enabled, so that MaxDB will
automatically output to a local filesystem whenever our log area becomes
too filled.  As it exists for us today, when MaxDB produces such an
AutoLog-inspired backup, the version files that get produced just sit in
the local filesystem until our regularly-scheduled Data Protector backup
comes along to move them to tape.  It is hoped that in the future, MaxDB
7.6 would (via the use of the Event Dispatcher) call DP after such an
AutoLog-inspired backup, and thus we'd prevent the possibility that our
local filesystem would fill up itself.

In the event you all decide to drop the Event Dispatcher, that's Ok... I
mean, we could always create a little daemon that could periodically
monitor this filesystem (and trigger DP accordingly), but we were
hopeful that the Event Dispatcher would be able to do that for us.

Thanks,
~Fred

Subject: Event Dispatcher: any feedback?

Hallo Users,
with MaxDB version 7.6 we introduced the feature "Event Dispatcher"
(pls. check
<http://dev.mysql.com/doc/maxdb/en/ab/61fe41af01c417e10000000a155106/fra
meset.htm> for documentation).

We have basically two questions concerning it:
1. Does it meet your requirements, in other words, can you use it? Which
events are the most interesting for you? Are there any situations resp.
occurences that should be provided as events to make them dispatchable?

2. We're currently discussing, if we should remove the Event Dispatcher
from the client to make the software (and it's installation) less
complex and the software download smaller. Is anybody using it on the
client (and would be hurt by the removal)?

Before you might ask:
For the time being, I'm afraid, it's not planned to have something like
"user defined events", that you can make the kernel fire by calling some
SQL statement.

T&R,
