Meaning – The term quiesce, refers to the process of ending a process by allowing operations to complete normally. In software applications that modify information stored on disk, this generally involves flushing any outstanding writes; see buffering. With telecom applications, this generally involves allowing existing callers to finish their call but preventing new calls from initiating.

Perhaps the best-known support for this was incorporated into Microsoft Shadow Copies which was introduced in Microsoft Windows Server 2003. For an application to be quiesced during the shadow copy process, it must register itself as a writer and it is responsible for putting itself into a quiescent mode upon notification.

Example of usage“In all caps, QUIESCE is the command line. Quiesce is a database function similar to restricted or adminmode. In quiesced mode, it allows database administrators to perform maintenance tasks in an exclusive or controlled mode.”
