The upgrade of the Enterprise Manager GridControl 10.2.0.5++ to 184.108.40.206 is not really heavy. Here a short decription. I my example I’m going to upgrade from 220.127.116.11 to 18.104.22.168:
First export EMKEY:
[oracle@cloudcontrol ~]$ /opt/oracle/middleware/oms/oms/bin/emctl config emkey -copy_to_repos Oracle Enterprise Manager Cloud Control 12c Release 2 Copyright (c) 1996, 2012 Oracle Corporation. All rights reserved. Enter Enterprise Manager Root (SYSMAN) Password : The EMKey has been copied to the Management Repository. This operation will cause the EMKey to become unsecure. After the required operation has been completed, secure the EMKey by running "emctl config emkey -remove_from_repos". [oracle@cloudcontrol ~]$
Then you have to shut down alle EM components:
[oracle@cloudcontrol ~]$ /opt/oracle/middleware/oms/oms/bin/emctl stop oms -all Oracle Enterprise Manager Cloud Control 12c Release 2 Copyright (c) 1996, 2012 Oracle Corporation. All rights reserved. Stopping WebTier... WebTier Successfully Stopped Stopping Oracle Management Server... Oracle Management Server Successfully Stopped AdminServer Successfully Stopped Oracle Management Server is Down
Now unpack the downloaded ZIP archives and start runInstaller:
Select new middleware home (the Installation is a Out of Place upgrade)
Set password for repository db connection
There are some requirements for a successful upgrade:
