DynamicCluster

This type is a class for model objects.

A dynamic cluster consists of a group of application servers. If one of the member servers fails, requests will be routed to other members of the cluster. The dynamic cluster membership changes dynamically during runtime according to the number of requests.

Package: dynamiccluster

Classifier ID:  -1
Instance class name:  * Unspecified *
Instance class:  * Unspecified *



Attributes Summary
isolationGroup : EString Specifies the group this dynamic cluster is a part of for grouped/shared isolation.
maxInstances : EInt The maximum number of running instances for a dynamic cluster is set to -1 by default for unbounded maximum. The acceptable entries for this field are integers equal to -1, or integers greater than or equal to 1.
membershipPolicy : EString * No description is available *
minInstances : EInt The minimum number of running instances for a dynamic cluster is set to 1 by default. This value is usually acceptable particularly for dynamic clusters that will be running in supervisedor automatic mode. The acceptable entries for this field are integers greater than or equal to 1. In the event a minimum value is set that is excessive, performance degradation will likely occur.
name : EString The name of the dynamic cluster has to be unique among dynamic clusters and clusters across the cell.
numVerticalInstances : EInt The number of instances allow to be started on the same node in the dynamic cluster is set to 0 by default, meaning disabled. If the nodes in the dynamic cluster have access processing capacity, vertical stacking will allow an application to make effective use of the capacity by starting multiple instances on the same node. The acceptable entries for this field are integers greater than or equal to 1.
operationalMode : EString The operational mode of the dynamic cluster dictates how it reacts to varying workloads. The mode may be one of three values: automatic, supervised, or manual. Automatic mode allows the WebSphere Dynamic Operations environment to handle placements and provisioning. Supervised mode is a combination of administering by WebSphere Dynamic Operations and the system administrator. The WebSphere Extended Deployment environment makes recommendations to the administrator, which the administrator may implement or disregard. Manual mode indicates no interaction from the WebSphere Dynamic Operations environment.
serverInactivityTime : EInt The time to wait in minutes before stopping all running instances in a dynamic cluster during periods of inactivity is set to 0 by default, meaning disabled. This is enabled when the minInstances is set to 0. The acceptable entries for this field are integers greater than or equal to 1.
serverType : EString * No description is available *
strictIsolationEnabled : EString This true/false value overrides the isolationGroup value, creating a strict isolation policy
minNodes : EInt The minimum number of nodes that should host running instances of a dyanamic cluster at any point in time.
maxNodes : EInt The maximum number of nodes that should host running instances of a dyanamic cluster at any point in time.
properties : Property * Some runtime components allow a collection of additional properties which can be used for further customization. See documentation related to the runtime component to determine if special properties can be used.
members : ClusterMember * A list of the servers that are members of this cluster.
