Lingering locks for replicated data objects |
摘要 |
In a network wherein replicas of a data object reside at a plurality of nodes, a node has a lock manager which handles requests for access to the data object by processes of differing nodes. When a process native to the node desires access to the data object, the lock manager sets a lingering lock flag in a lock table for the data object. Setting the lingering lock flag indicates that the data object can only be accessed at the node to the exclusion of processes of other nodes. The lingering lock flag can remain set after the process native to the node terminates access to the data object, thereby enabling a successive access to the data object by the same process or another process native to the node, such successive access being without notification to other nodes of the network.
