Cluster Members (Components tab)
The Server Tools Cluster Members – Components tab provides information on the components running on the server that you select in the Cluster Members (Application Server Instances) table. These components, with the exception of the work queues, are all singleton components. You can view all components, or, filter the list to see only those components of a specific type.
The Components table provides the following information about the components running on the selected server.
Type |
Type of component, one of the following:
|
Name |
Name of component. This name is the work queue name, or, the message destination name, for example. |
Started |
Date and start time for each component. |
State |
State of the component, for example, Assigned. |
Retry Failover |
Date and time of the deadline in which to complete the failover process. If a lease manager detects the expiration of a component lease owned by another cluster member, the first lease manager starts a failover process for this lease. This failover process is not instantaneous. It is possible that during the failover process the cluster member performing the failover itself might fail, or lose database connection, or encounter other potential problems. To be able to handle this situation gracefully, the cluster member starting the failover gives itself a deadline to complete the failover process. If the current failover process does not finish by the specified timestamp, some other cluster member needs to start the failover process for the same component lease. See Automatic failover of a component lease for a description of how PolicyCenter calculates this timestamp. |
You can view similar information to that of the Components table on the Cluster Components screen.
