As it happens I'm in the middle - well near the end actually - of a Grid
Control installation for a company that has invested quite heavily in the
Oracle product stack. So we are talking DB, Weblogic, SOA, BIEE, EBS and so
on. To monitor some of these products in their latest guise requires 11g EM.
I've had some dealings with support during this time :) In fact I've had to
log 12 SRs - 2 of which were clearly my fault. Split by category they are

    *Discovery Issues* 2 *Installation Issues* 3 *Licensing Issues* 2 *Metric
Errors* 5

All the metric collection issues and 1 of the target discovery issues are
still open. At least one of the Metric collection errors is likely to mean
that in order to completely monitor a java application we'll have to upgrade
the JDK on which it runs. FWIW all but 1 of the issues applies to areas
other than the DBMS some of which *cough* soa *cough* are somewhat bleeding
edge.

In addition I have another 8 distinct classes of Metric Errors that I will
not be logging an SR for, but which in my view represent bugs (you shouldn't
try and collect operational metrics when a target is down it'll only end in
tears)

I'm also expecting to end up raising some SRs about clearing Alerts when the
underlying problem has gone away.
