Class NodesLockRestorationManager

java.lang.Object

org.ow2.proactive.resourcemanager.core.recovery.NodesLockRestorationManager

public class NodesLockRestorationManager
extends Object

Encapsulates the logic about Nodes lock restoration upon Resource Manager restart.

It was decided to keep the mechanism simple by considering the node source name only when the lock restoration is made. The hostname does not enter into account.

Considering the hostname is non-trivial since it is not stable. It may change on machine restart or due to node state change. Besides, some infrastructures are dynamics and the number of nodes deployed from a restart to another may differ.

This class is not thread-safe.
