Use this page to specify settings for the first cluster member.

There are two ways to create the first member of a cluster:

When you create the first cluster member, a copy of that member is stored as part of the cluster data and becomes the template for all additional cluster members that you create.

When adding servers to a cluster, remember that the only way to remove an appserver from a cluster is to delete the appserver from the list of cluster members.

Member name

Name of the appserver that is created for the cluster.

The member name must be unique on the selected node.

Select node

Node on which the appserver resides.

Weight

Amount of work that is directed to the appserver.

If the weight value for the server is greater than the weight values that are assigned to other servers in the cluster, the server receives a larger share of the cluster workload. The value can range from 0 to 20. Enter zero to indicate that you do not want requests to route to this appserver unless this server is the only server that is available to receive requests.

Core group

The core group in which the appserver resides.

This field displays only if you have multiple core groups configured. You can change this value only for the first cluster member.

Generate unique HTTP ports

A unique HTTP port is generated for the appserver. By generating unique HTTP ports for the appserver, you avoid potential port collisions and configurations that are not valid.

Select basis for first cluster member:

If you select...

Create the member using an appserver template

...the settings for the new appserver are identical to the settings of the appserver template you select from the list of available templates.

If you select...

Create the member using an existing appserver as a template

... the settings for the new appserver are identical to the settings of the appserver you select from the list of existing appservers.

If you select...

Create the member by converting an existing appserver

...the appserver you select from the list of available appservers becomes a member of this cluster.

If you select...

None. Create an empty cluster

...a new cluster is created but it does not contain any cluster members.

The basis options are available only for the first cluster member. All other members of a cluster are based on the cluster member template which is created from the first cluster member.
