Dynamic cluster collection

Use this page to view your existing dynamic clusters. The members of the dynamic clusters, or server instances, reside on a node within a node group. The dynamic clusters, as well as the associated node groups, are used to perform application placement when the environment is running in automatic mode.

To view this administrative console page, click Servers > Clusters > Dynamic clusters.

You must have monitor privileges to view dynamic cluster information. For other administrative roles and privileges information, see the information center.

Name

Specifies a name for the dynamic cluster. The name for a dynamic cluster must be unique among all the clusters in the cell.

The name field cannot contain the following characters: # \ / , : ; " * ? < > | = + & % ' . The name cannot begin with a period (.) or a space. A space does not generate an error, but leading and trailing spaces are automatically deleted.

Type

Specifies the type of servers that are being used in the dynamic cluster.

The following list contains the server types:

WebSphere® Application Server: Specifies that the dynamic cluster contains application servers that are running WebSphere Application Server Intelligent Management.
Liberty profile server: Specifies that the dynamic cluster contains Liberty profile servers.
Apache server: Specifies that the dynamic cluster contains Apache servers.
Custom HTTP server: Specifies that the dynamic cluster contains HTTP servers.
JBoss server: Specifies that the dynamic cluster contains servers that are running JBoss Application Server.
On demand router: Specifies that a dynamic cluster of on demand routers is being created.
PHP server: Specifies that the dynamic cluster contains servers that are running PHP.
Apache Tomcat server: Specifies that the dynamic cluster contains servers that are running Apache Tomcat.
WebSphere Application Server Community Edition server: Specifies that the dynamic cluster contains servers that are running WebSphere Application Server Community Edition.
BEA WebLogic server: Specifies that the dynamic cluster contains servers that are running BEA WebLogic.
External WebSphere application servers: Specifies that the dynamic cluster contains servers that are in other cells. These cells might be running other versions of WebSphere Application Server, such as Version 5.1 or 6.0. You can map these static clusters to a dynamic cluster.

Operational mode

Specifies the level that the dynamic cluster interacts with the dynamic operations environment.

Manual: In manual mode, the dynamic cluster is no different than the normal application server environments with static clusters. No interaction with the dynamic operations environment occurs.
Supervised: In supervised mode, the intelligent management environment provides information and recommendations for actions that the administrator can use.
Automatic: In automatic mode, the intelligent management environment takes actions automatically. In automatic mode, the dynamic operations environment handles placements and provisioning.

To change the operational mode, select the clusters that you want to change, select the mode type that you want to define, and click Set mode.
