it is still available to users for read-only queries. Microsoft Windows SharePoint Services 3.0 and Microsoft Office SharePoint Server 2007/2010 support a QUIESCE or QUIESCE FROM TEMPLATE (2010) option within the Central Administration operations window. This allows an administrator to stop the server farm from accepting new user connections and gradually brings any long-running applications offline without causing data loss. JADE Object Oriented Database system can perform a quiesced backup with the parameter 'quiesced=true'. The database is placed in a quiescent state by allowing current active transactions to complete and then flushing modified buffers from cache to the stable database. During a quiesced backup, updating transactions are not permitted and attempts to execute database transactions raise a database exception. Microsoft Visual Studio Team Foundation Server supports quiesce functionality by using the TFS Service Control command-line utility. More information exists about this command-line utility in the MSDN Library. A Microsoft Knowledge Base article describes it by indicating that it disables access to Team Foundation Server services for the duration of servicing operations.
