    Update Rollup 3 (UR3) for OpsMgr 2012 SP1 shipped originally several months back.  I took a cautious approach to this update, as there were some components pulled early for DPM (all have been resolved).  Does not look like anything was an issue in SCOM, beyond the known issues documented at...
  • Blog Post: Do I need a specific Cumulative Update Release (UR) in order to upgrade to SCOM 2012 or 2012 SP1 or 2012 R2?

    There is sometimes confusion over upgrades, if you can just upgrade to the next version, or if there is an CU (Cumulative Update) or UR (Update Rollup) minimum level that is required BEFORE a major version upgrade. The MAJOR VERSION upgrade path is below, which Marnix talked about HERE . This article...

    Given the recent support of Server 2008 with an OpsMgr 2007 agent.... (see Announcing OpsMgr support for Windows Server 2008 )  We need a good way to determine if all of our Server 2008 machines have the required hot-fixes.   We can do this by creating a Extended Class, and adding attributes...

  • Blog Post: Do you randomly see a MonitoringHost.exe process consuming lots of CPU?

    Randomly, you might see a single MonitoringHost.exe process on an agent, consuming 100% CPU. (Or 50%, or 25% depending on how many cores you have).  This process will stay at this level, and will not recover.  If you restart the OpsMgr HealthService, the problem goes away, and might not return...

    Something I noticed today..... when you deploy a gateway server - the helper object oomads.msi was not copied to the local \ AgementManagement directory for agent push.
