In this cloud-era it’s almost weird to explore stuff on-premises, but I did…. In this case a slightly Higher Availibility configuration of Oracle Enterprise Manager (OEM) that doesn’t cost anything, is not disruptive to the existing configuration and gives a tiny bit more confidence during patching of OEM : Always On Monitoring (AOM). Maybe a bit underrated functionality – within Oracle .

Despite the potential of Oracle Management Cloud, I’m a fan of Oracle Enterprise Manager, with its small imperfections. So when noticing a 12c Oracle Enterprise Manager on Linux, and targets on Windows, I took the challenge of modernizing the customer’s environment a bit. And the starting point , 12.1.0.5 for OMS and 12.1.0.2 database as repository wasn’t that bad at all. This post is purely about upgrading the OMS.
