I finally had a chance to try this out. Unfortunately, even though
connect.pl says "OK", after PMDA installation there are no oracle
metrics available and the Oracle PMDA log is silent.

Are there any recommended sanity checks that could be done in this case?
Like Oracle version / configuration / etc?
