Guest blog series by Hans Forbrich, Forbrich Consulting Ltd.
I have been teaching Oracle technology for over ten years, and using and consulting on that technology for nearly 30 years. It never fails to amaze me how many myths persist around the product set.
This is particularly true around the Oracle Enterprise Management set of products.
This blog is the first in a series of posts over the next several days that will address some of the more persistent myths I hear at conferences and in the classroom.
Myth 1: There are too many versions. It’s all confusing.
Oracle Enterprise Manager is a family of products. With the right roadmap, it is not really all that difficult to navigate Oracle Enterprise Manager.
Oracle Enterprise Manager stand-alone products:
First of all, since Oracle Database 10g, there has been a stand-alone ‘database’ control. In reality, it is just an implementation of Oracle Enterprise Manager with a dedicated app server, repository built into the database being monitored, dedicated agent, and the database plugin configured by DBCA.
A counterpart to the stand-alone database control is the stand-alone Fusion Middleware Control. It can monitor and manage applications deployed to WebLogic Server domains.
Oracle Enterprise Manager Grid Control:
Oracle released the first version of Grid Control, which allowed the repository, application server, and agents to be installed separately. Unfortunately Oracle decided to label the patch sets as releases, which is inconsistent with the other products.
Grid Control 10g used Oracle OC4J as the application server. The most significant “visible” change in Grid Control 11g was replacing the OC4J with the more modern WebLogic Server.
Grid Control 10g and Grid Control 11g are able to monitor and manage a variety of Oracle product versions. For example, the OMS 11g (220.127.116.11) with Agent 10g (10.2.0.5) can monitor Oracle9iR2 Database (18.104.22.168 and higher).
Oracle Enterprise Manager Cloud Control:
Grid Control is now obsolete.
Oracle Enterprise Manager Cloud Control 12c is simply the next generation of Grid Control. It has many new capabilities, a significantly enhanced user interface, and a number of changes in the security model. Other than the dramatic flexibility enhancements in the UI, this retains a lot of similarity to the Grid Control.
The Oracle Enterprise Manager Cloud Control 12c can monitor and potentially manage all currently-supported Oracle products. According to the Support certification information, Oracle Enterprise Manager Cloud Control 12c (22.214.171.124) can monitor and manage Oracle database 9iR2 (126.96.36.199).
Oracle Enterprise Manager Operations Center:
Sun Microsystems had a successful central management console oriented closely to the needs of SysAdmins. This product has been retained and enhanced as the Oracle Enterprise Manager Operations Center, specifically for automations of Linux and Solaris environments.
Oracle’s OTN website provides the general product technical portal found athttp://www.oracle.com/technetwork/indexes/products/index.html
All of the Oracle Enterprise Manager Cloud Control 12c documentation is athttp://docs.oracle.com/cd/E24628_01/index.htm
Visit the Blue Medora blog again tomorrow and Hans will debunk Oracle Enterprise Manager Myth #2: Enterprise Manager is too new to be useful.
