Disk Space Requirements for the Operations Console

  • Article

When you launch the Operations Console on your workstation or even on the management server (or RMS for that matter), the data from the Operations Manager database is cached locally in the file "momcache.mdb." By default, the console will poll the SDK Service on the RMS every 15 seconds to update the local cache.  Depending on the number of agent managed systems that are in the management group, potential size of the database will be (as indicated by the Product Group): 

  • 100 server deployment = 300 MB
  • 1000 server deployment = 600 MB
  • 5000 server deployment = 1 GB

The database file is located in %USERPROFILE%\Local Settings\MIcrosoft\Microsoft.Mom.UI.Console. 

For my small lab environment with only 12 servers being actively monitored by Operations Manager with many core and custom management packs, the file size is 34 MB (as an example).

So if you are intending or are already hosting the console on a Terminal Server or Citrix Server, you will need to factor this in to ensure you don't impact the volume supporting other shared applications.
