I'm writing an AM that accesses a database. I would like to
perform a few application specific calls in the PROBE
initialization. If the application specific calls fail,should
an MCC error status be returned, or should success be returned
and then when the directive is issued, an error "not properly
initialized" be displayed? Ideally, I would like to return
a meaningful error to the user, but I don't see how.
Also, I would like to store the database name on startup in
global memory. Is this an accepted practice?

The probe entry point is not a great place to communicate meaningful
status to the user for the reasons you mention; however, if something
as disastrous as failure of an MM to initialize occurs during probe
I would simply printf from the MM - yeah it breaks the rules but it's
better than the "Disappearing MM for no reason" approach.
Since the probe entry point is called once per MM activation, it *is*
a logical place to put once time initialization (like storing a DB
name in global memory). The SRM does say this.
