Administration Groups in EM12c Date: 04/02/2012 Author: Rob Zoeteweij http://oemgc.wordpress.com In previous releases of Enterprise Manager, we were able to create Groups that allowed us to monitor a group of Targets that were logically related. For instance specific groups based on the Lifecyle phase (Development, Test, Acceptance, Production), of based on the specific SLA the Targets were assigned to. A great way to organise Targets and to focus on specific Groups in your monitoring setup. A drawback however, when looking at maintaining these groups. In too many situations at Customer sites, assigning newly created Targets to a specific Group simply was forgotten. This often resulted in incomplete monitoring of specific Targets. Enterprise Manager 12c brings us a solution to this problem by introducing ‘Administration Groups’. When setting up an Administration Group, you need to identify specific Target Properties like ‘Department’, ‘Line of Business’, ‘Lifecycle Phase’ and others to relate to a certain level in the Administration Hierarchy. Where a Hierarchy might be based on multiple Properties. If then for instance, a Target get’s assigned a specific ‘Line of Business’, the Target will be assigned automatically to the appropriate Group in the Hierarchy. By this you will be sure each Target is assigned to the right Group. Let’s see how we can setup such an Administration Group. From the Setup menu select Add Target à Administration Groups
Select the “Hierarchy” Tab or select the Setup Administration Group Hierarchy link
Next press the [Add] Icon at the Hierarchy Level
Select Lifecycle Status
As we can see, an Hierarchy is automatically created based on the 5 predefined Lifecycle statuses ‘Development’, ‘Mission Critical’, ‘Production’, ‘Staging’ and ‘Test’ We notice that all names for the Groups are created by default ‘Dev-‐Grp’, ‘MC-‐Grp’ etc. In this example we will change these names
Select the Deve-‐Grp link that will bring up a Dialog allowing you to change the name. In this example we will use ‘DEV_GROUP’. In the same way we will change all other names to: ‘MSC_GROUP’, ‘PRD_GROUP’, ‘STG_GROUP’ and ‘TST_GROUP’
In this example we will merge both the Development and Test Group as these Groups will be monitored similar.
Under ‘Hierarchy Nodes’ we will both select Development, Staging and Test and select Edit à Merge
We will do the same with the Mission Critical and Production Groups
Next we will change the names to ‘PRE_PRD_GROUP’ and ‘PRD_GROUP’ We will now extend the Hierarchy with the ‘Line of Business’
To do so we will select the [Add] Icon at ‘Hierarchy Levels’ and select ‘Line of Business’
We notice that the Line of Business level is included in the Hierarchy, showing the ‘FINANCE’ and ‘SALES’ Line of Business. These Groups could have been included simply because of the fact that several Targets have been assigned a ‘Line of Business’. You can do this starting at the Target Home page and then select Targets Setup à Properties Before we finalize the creation of the Group, we will first change the names of the ‘Line of Business’ Groups to: ‘PRE_PRD_FINANCE_GROUP’, ‘PRE_PRD_SALES_GROUP’, ‘PRD_FINANCE_GROUP’ and ‘PRD_SALES_GROUP’. Press the [Create] button and acknowledge the Confirmation
Next we will navigate to the Group Targets page
Select Targets à Groups
The Groups Pages shows the Administration Group we just created It also shows the Targets and number of Targets that are member of this Group, as well as Status and Incident information
After expanding the Top Level, the complete Hierarchy is shown as we just created it We notice that Group ‘PRD_FINANCE_GROUP’ does not have any Members. The beauty of Administration Groups is: that as soon as a Host or Database Instance is assigned Line of Business ‘FINANCE’ it will become a Member of this Group automatically! What we will do next is assign a new Database to the ‘FINANCE’ Line of Business In this example we have just created a new Database orcl5.mycorpdomain.com, which should be assigned to the ‘FINANCE’ Line of Business. When in the Database Homepage, we select from the Database menu Target Setup à Properties
Next we enter ‘FINANCE’ as the Line of Business the Database Instance needs to be assigned to. If we now take a look at the Groups Targets Page we will notice that the Database was automatically assigned to Group ‘PRD_FINANCE_GROUP’
When selecting the Top Level Group ADMGRP0, we will get this nice Console view
What next? Well we could now start assigning Template Collections to each of these Groups, in order to setup monitoring. Just check for new postings on my Blog
