Clusters: Configuration: Health Monitoring
Configuration Options Related Tasks Related Topics
This page allows you to configure the health monitoring characteristics for this cluster. WebLogic Server provides a self-health monitoring capability to improve the reliability and availability of servers in a WebLogic Server domain. Selected subsystems within each server monitor their health status based on criteria specific to the subsystem.
Configuration Options
Name Description Inter-Cluster Comm Link Health Check Interval If the cluster link between two clusters goes down, a trigger will run to periodically to see if the link is restored. The duration is specified in milliseconds.
MBean Attribute:
ClusterMBean.InterClusterCommLinkHealthCheckInterval
Health Check Interval Interval in milliseconds at which Migratable Servers and Cluster Masters prove their liveness via the database.
MBean Attribute:
ClusterMBean.HealthCheckIntervalMillis
Changes take effect after you redeploy the module or restart the server.
Health Check Periods Until Fencing Maximum number of periods that a cluster member will wait before timing out a Cluster Master and also the maximum number of periods the Cluster Master will wait before timing out a Migratable Server.
MBean Attribute:
ClusterMBean.HealthCheckPeriodsUntilFencing
Minimum value:
2
Changes take effect after you redeploy the module or restart the server.
Fencing Grace Period During automatic migration, if the Cluster Master determines a server to be dead, it waits for this period of time (in milliseconds) before the Cluster Master migrates the service to another server in the cluster.
MBean Attribute:
ClusterMBean.FencingGracePeriodMillis
Changes take effect after you redeploy the module or restart the server.
