the error code -24998 is a DBMServer error code. It means that the DBM
command, that you tried to executed is not yet implemented (btw, could
you tell me what you did to get this error code?) in the DBMServer. In
other words, you had an error in the DBMServer. The only source for
events that are available via event_wait is the database kernel, not the
DBMServer, so you got no event.

Events of the event category ERROR are fired by the kernel in case the
kernel has a severe problem and makes an error entry in knldiag log
file.

The topic of events is not up to date in the documentation available at
<http://dev.mysql.com/doc/maxdb/en/default.htm>, I'm afraid. The next
version of the documentation, which will be available this summer, will
cover this more adequately.

The MaxDB Event Dispatcher might be interesting for you (you have it
already, it will be documented in the next version of the
documentation). It allows you to connect an action with the emersion of
an event. The action could be the execution of a DBMServer command or a
3rd-party-program.

Marc-Philip
