Oracle Enterprise Manager - Exploring Licensing (13cR2) - Part 2

If you have followed my last blog on OEM Licensing, you should have been pretty clear on what all licensing requirement you do have for OEM.
In this blog I am going to highlight few more aspects of OEM licensing.

1. Every Database that needs to send notifications should have Diagnostics Pack enabled. 
Yes, you read that right, if you want to send notifications for any database, you must have Diagnostics Pack, that means you must have Enterprise Edition, else you cannot send a notification for the same. 
This means ideally you cannot send any notification for Standard Edition Databases.

However, since host based notifications are free and are included in Base Manager Functionality, you can use them.

(This is ofcourse how your licensing team gets license from Oracle ;)

2. OEM has 2 components OMR and OMS. I have made it clear on licensing aspects of OMR.
Now let me shine some light on OMS. OMS is available free as part of restricted license from Oracle for one instance only. 

What I mean is that if you want to setup a Weblogic Cluster for HA, then you need to buy that separately

Use of Oracle WebLogic Server with Oracle Enterprise Manager is restricted to the servlet functionality without clustering for the Oracle Management Server (OMS).

Use of Oracle WebLogic Server with Oracle Enterprise Manager is restricted to servlet functionality. A restricted-use license for WebLogic clustering is included, to support deployment of cluster of Oracle Business Intelligence Publisher servers, only when used with Oracle Enterprise Manager.

multiple OMS can be run for scalability but can’t be clustered unless it is purchased separately
