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 > 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 or WebSphere Virtual Enterprise.
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.
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 WebSphere Virtual Enterprise environment provides information and recommendations for actions that the administrator can use.
  • Automatic: In automatic mode, the WebSphere Virtual Enterprise 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.
