I've run it no probs on W2k but cannot connect via the browser when the OMS is on unix (AIX 5.1).
I have run through the setup correctly (oemctl configure rws, new passwd for reports_user etc etc) but just get:
Generation of the report failed because a connection could not be made to the
Oracle Management Server ibrisha_ms01. Ensure that the Oracle Management Server
is running and that the webserver has been appropriately configured for
Enterprise Manager Reporting.
Currently waiting for Oracle UK to get 9.2.0 installed so they can try to recreate it! mmmmmm...
