public LoadBalancingPolicy()

Method Detail

getPolicyTypeFromOperationId

public String getPolicyTypeFromOperationId(int operationId)

returns current load-balancing policy from desired operation id

getOperationName

public static String getOperationName(int operationId)

Converts load-balancing operation from int to String

getRecoverableTargets

public List<SpaceURL> getRecoverableTargets(String clusterName,
                                            String myMemberName,
                                            List<String> excludeTargets)

Finds all the recovery targets in cluster. If jini URLs are used, the first target will always be multicast url. only if it fails the unicast and rmi URLs will be used.

Parameters:

clusterName - the cluster to recover in.

myMemberName - the member of the cluster that needs to be recovered.

excludeTargets - targets that should be excluded from recovery

Returns:

a list of recoverable members SpaceURLs. returns empty list if recovery is disabled.
