Oracle Enterprise Manager Cloud Control 12c Release 5 ( is Ready to Download

Enterprise Manager Cloud Control 12c Release 5 is avaliable to download. The new release is designed to monitor and manage both your on-premise and Oracle Cloud deployments which is called “Hybrid Cloud” by Oracle. You can deploy Management Agents onto the Oracle Cloud virtual hosts to manage Oracle Cloud targets just as you would any other targets. EM12c R5 also supports data cloning between on-premise and Oracle Cloud. Integration with Oracle Enterprise Manager Ops Center will help dynamic on-demand resource provisioning.

I’m planning to upgrade our EM12c Release 4 to Release 5 in a couple of days, and discover the new features. Maybe I may write a couple of blog posts about upgrading or installing the new release.


As you may know, EM12c R5 was announced a couple of days ago, so I was regularly checking the download page, and noticed that EM12c never gets old, it is always NEW 🙂

Oracle Enterprise Manager EMCLI on Mac OS X

EMCLI is not certified or supported on Mac OS X, but I wondered if it is possible to run on my new macbook. I searched metalink, googled and couldn’t found any useful information. I thought it should be easy because EMCLI is a java application certified to run almost all enterprise operating systems including HP-UX, AIX, Linux, Windows, Solaris, and we all remember “write once, run everywhere” slogan of Java. Unfortunately it wasn’t as easy as I expected 🙂

I have downloaded emclikit.jar from my Enterprise Manager web console, and tried to install it. Here’s the output:

Oracle Enterprise Manager EMCLI and Java 1.8

Java 1.8 is the current version and you probably use it on your personal computer. Although EMCLI says it will work on Java 1.6 and newer versions, if you install it using Java 1.8, you get an error when you try to setup or synchronize it with the Enterprise Manager Cloud Control OMS server. The reason is that Java 1.8 will use TLS 1.2 as default protocol for secure connections.

To fix the problem, you need to download and apply Patch 17555224 for FMW version. You can learn more from My Oracle Support Doc ID 1930390.1.

How to Recover Weblogic Administration Password of Enterprise Manager

As you may know, Weblogic is a part of Enterprise Manager Cloud Control environment, and it’s automatically installed and configured by the EM installer. The Enterprise Manager asks you to enter a username and password for Weblogic administration. This information is stored in secure files, and you usually do not need them unless you need to use Weblogic console. So it’s easy to forgot these username and password, and that’s what happened to me. Fortunately there’s a way to recover them without even resetting new user/password. Here are the steps:

First we need to know DOMAIN_HOME directory. My OMS is located in “/u02/Middleware/oms”. You can find yours if you read “/etc/oragchomelist”. If the full path of OMS is “/u02/Middleware/oms”, my middleware home is “/u02/Middleware/”. Under my middleware home, I need to go GCDomains folder:

First let’s get the encrypted information from file:
