Upgrading using the 2-system upgrade approach (on a different host)


In this upgrade approach, the EM Cloud Control installation is carried out on a host that is different from the host where the existing EM is already running. It does not upgrade the existing Management Repository database, but upgrades the one on a different target, typically from a backed-up database, hence enabling the two EM systems to coexist. Minimal downtime is involved as a part of this upgrade approach.

Getting ready

Before you start, ensure that the server where the previous version of OEM is running is connected to the network, and an SSH or a telnet client is available. Also make sure you have access to the Unix server as rootuser, owner of Oracle repository database, and OEM.

The following environment details are used to demonstrate the 2-system upgrade approach in this example:

  • Operating system: Oracle Enterprise Linux 5 Update 3

  • Repository Database 11g release 2 is installed at /dboracle/product/11.2.0/dbhome_1...
