Quiescing the Server Farm

Posted: October 21, 2008 in Quiescing

This is a feature in MOSS that enables you to gradually shut down the farm for maintenance. This feature is called “Quiescing

Quiescing is the process of gradually bringing long-running applications of a resource offline without incurring data loss. It has been introduced in Microsoft Office servers for 2007.”
So if you need to perform maintenance on a farm, you “quiesce” it. IMHO, something like “Take Farm Offline” would have been a better choice.

Why should you use the quiesce feature?

  • Simply put, to prevent data loss.

How do you quiesce the farm?

  • From Central Administration, Operations, select “Quiesce Farm.”
  • Enter the number of minutes in which you want the farm to be fully quiesced and click “Start Quiescing.”
  • The page will display the quiescing status

Quiescing has three states: normal, quiescing, and quiesced.

  • Normal is the active state in which the farm handles all requests that come into it.
  • Quiescing is the state in which the farm only handles requests from existing sessions
  • Quiesced is the state in which the farm does not allow any new sessions to start.”

How do you “un-quiesce” (reset) a farm:

  • From Central Administration, Operations, select “Quiesce Farm.”
  • Click “Reset Farm.” Why couldn’t they have come up with an obscure word for “reset?”
