Adding the Active Directory helper object (OOMADs) to DC servers.

Hi Experts,

I have recently got alerts form one of our DC machines.

It says The script 'AD Replication Partner Op Master Consistency' failed to create object 'McActiveDir.ActiveDirectory'.  The Active Directory Management Pack Objects (OOMADs) components are not installed on the Domain Controller.  These components are required for the monitoring scripts to run successfully.

We haven't installed Active Directory helper object (OOMADs) separatley to the DC servers. I went through the AD 2008 management pack guide.

There are few items under optional configuration, PFB :

  1.    Collecting Replication Performance Data
  2.    Client Monitoring
  3.    Enabling Agent-Only Discovery
  4.    Placing Monitored Objects in Maintenance Mode

Does the above optional configurations needs to have OOMADs separately installed. ?

What is the main purpose of of having this OOMADs.msi addtionally instlled.  ?

Steps to install the OOMADs ?

What are the set of permisions needed for the action account ?

Eagerly looking forward for your expert comments.

Thanks in Advance.

Hi, installing Active Directory Management Pack Objects (OOMADs) it's an important part of functioning AD MP correctly as you can see it states "These components are required for the monitoring scripts to run successfully."

you can export AD MPs to xml and you will see where object 'McActiveDir.ActiveDirectory' is used.

to install OOMADs you only need to run OOMADs.msi manually (with correct version (x86, amd64))

as for action account, local system

Hi 

Does the above optional configurations needs to have OOMADs separately installed. ?

If you deploy the SCOM Agent this OOMADs gets installed autmatically if you deploy an Agent to a DC. If you install the SCOM Agent manually you Need to installt OOMAD manually Fact is you Need this component on your Domain Controller to monitor properly. It doesn't matter what configurations from the AD MP you choose.

What is the main purpose of of having this OOMADs.msi addtionally installed?

It is an Additional Piece of software to the SCOM Agent to utilize the AD MP functionality to it's full degree.

Steps to install the OOMADs ?

Just execute the MSI which you will find in the AgentManagement Directory on your SCOM Management Server.

What are the set of permisions needed for the action account ?

Local System

Hi Stefan and Alexis,

Thanks a lot for your responses.

Just to understand, any ideas what are the parameters that would go unmonitored if this ADMP helper object OOMADs.msi is not installed separately ?

As this change needs to be performed on the DC machines, i am liable to a flood of cross questions :)

So just getting my self prepared for it with your help :)

Hi

Besides the alerts you will not have fully monitored your AD.

Check These http://blogs.technet.com/b/janelewis/archive/2010/05/14/optimizing-and-reducing-the-noise-on-admin-packs-scom.aspx and http://technet.microsoft.com/en-us/library/hh212915.aspx .

You need to understand that it is a "must" to install this component.

Check also the MP Guide!

Thanks a lot Stefan.... your responses have been of great help in understanding the concepts realated to AD monitorings and OOMADs.

Learning :

To enable SCOM to monitor Active Directory to its full degree, we need to have an additional Active Directory Management Pack Objects (OOMADs.msi) component to be installed on all the DC servers.

There are multiple scripts run by the SCOM agent to monitor many aspects in case of AD monitoring. The ADMP COM helper object, OOMADs, is used by several ADMP monitoring scripts for making system calls that are not available in Microsoft Visual Basic Scripting Edition (VBScript).

Steps of install OOMADs.msi

               

  •             Check the architecture of the domain controller (32 or 64 bit)
  •             Locate ADMP helper objects installer (OOMADs.msi)  atC:\Program Files\System Center Operations Manager 2007\HelperObjects.
  •                                 Folders present  : amd64 for 64bit and i386 for 32bit
  •            Double-click the OOMADs file to install the Active Directory Management Pack helper object
  •             Restart the System Center Management service once.
  •             Once installed, Check the folder Program Files\System Center Operations Manager 2007\AgentManagement\<cpu architecture> contains the    file OomADs.msi

I've got a better idea, why don't they fix the management pack to take care of this oversight?   Oh, and you could put this information into the DOCUMENTATION don't you think?

Make a mistake? It's as designed.  Simply unbelievable.  With SCOM it's just one thing after the other.

Typical response from a user who cant configure things on their own.

Typical response from someone who's fine with sloppy work.

Bugs, errors, no documentation?  OK with you.  Don't want to set the standards too high.
