MOS Benefits: "Improved System Stability" .."Faster Problem Resolution"..errare humanum est the output of OCM (Release: 10.3.2.0.0) that it send to oracle is collected in $ORACLE_HOME/ccr/state. I can see four files on my system, 2 per RAC database. The *stat files contains information about feature usage, high water marks etc. pretty innocent (although I expect a link between "feature usage" and oracle corp's licensing departement, cq sales) I can see vip hostnames being sent because they are spfile parameter values (e.g. *listener) but not any other ip address or mac address. Where did you see that MAC address is being sent to oracle" I use OCM in connected mode for my 11.2 test system with OCM 10.3.2. I was hoping to be able to log SR more quickly using uploaded system configurations but unfortunately it failed with "Unable to process request for SERVICE_FETCH_CONFIG_CONTEXT_FOR_SR_DETAILS" in previous metalink and I haven't been able to create a new SR in MOS. Anyway, the OCM help output indicates that you can disable any uploading using the commandline. $ORACLE_HOME/ccr/bin/emCCR help Oracle Configuration Manager - Release: 10.3.2.0.0 - Production Copyright (c) 2005, 2009, Oracle and/or its affiliates.
