SCOM 2012 – Maintenance Mode Tool V 1.0

We’re all familiar with the Maintenance mode tool created by Ryan Andorfer, well Stefan Roth has created a utility for SCOM 2012 using the same look and feel. Well done Stephan.

I do need to note that this utility comes with a disclaimer to use at your own risk.

I’ve included the tool below, if you run into any issues or unexpected results the utility page is here  leave Stephan a comment so he is aware of it.



SCOM: Exporting and Importing User Roles

I came across a great article by Jimmy Harper on how to export and import SCOM user roles and notifications. I’ve dealt with migrating notifications in the past but it is refreshing to see that a method exists which allows the same to be done for user roles. It certainly makes working with side-by-side deployments that little bit easier.

Article and Method.



SCOM 2012: The System Center Management service stops responding after an instance of SQL Server goes offline

Update: this issue also applies to SCOM 2012 R2 as confirmed in this article by Kevin Holman

Microsoft released a KB article on the 5th of December on how to deal with a particular issue in SCOM 2012 SP1. It may be worth applying this fix preemptively if you are still running SP1, in order to avoid unnecessary downtime.

“After an instance of Microsoft SQL Server that hosts the OperationsManager database goes offline, the System Center Management service of the Microsoft System Center 2012 Operations Manager Service Pack 1 (SP1) management server stops responding.

For example, the System Center Management service stops responding after the instance of SQL Server disconnects, restarts, or fails. To recover from this issue after the instance of SQL Server is available again, you must restart the System Center Management service. “

NB: As always backup your registry before making any changes

To resolve this issue, you can enable the automatic recovery feature in System Center 2012 Operations Manager SP1. By default, this automatic recovery feature is disabled. 

To enable the automatic recovery feature on the management server, follow these steps:

  1. Start Registry Editor.
  2. Locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\System Center\2010\Common\DAL
  3. Create the following two registry entries:
    • DALInitiateClearPoolType: DWORD
      Decimal value: 1
    • DALInitiateClearPoolSecondsType: DWORD
      Decimal Value: 60Note The DALInitiateClearPoolSeconds setting controls when the management server drops the current connection pool and when the management server tries to reestablish an SQL connection. We recommend that you set this setting to 60 seconds or more to avoid performance issues.
  4. Restart the System Center Management service on the management server.
