  • Finer grained quiescence for data replication
    Patent number: 5991768
    Abstract: A method and apparatus for performing an administrative function on an object, replicated at a plurality of sites, suspends or "quiesces" replication activities at the granularity of an object group. Each object resides in an object group, and each object group has a status flag that indicates whether replication activities are quiesced. In response to detecting a request to perform an administrative function on an object, replication activities are suspended for the object group. Previous transactions are propagated to other sites. When each site has propagated all the previous transactions, the administrative function is performed and replication activities for the object group are resumed.
