Configuring communication between core groups that are in the same cell

If core groups that are in the same cell need to share workload management (WLM) information, then you must configure these core groups to communicate.

Before you begin

Create the core groups for your cell. Configure all of the processes within the core groups, including your servers and clusters.

About this task

You might configure multiple core groups for a cell in the following scenarios: With WebSphere® Application Server Network Deployment, a number of steps are required to configure this communication, including configuring bridge interfaces and core group access points. With WebSphere Extended Deployment, this configuration is simplified because these required elements are automatically configured.

Procedure

  1. Create the core groups for your cell.
  2. Add node agents and servers to each core group. Configure at least two node agents for each node group to ensure high availability. On process startup, if core group bridges have not already been configured, then every WebSphere Extended Deployment process automatically configures a core group access point for each configured core group. WebSphere Extended Deployment assumes that each of the node agents in each core group is a core group bridge. The configuration is modified to make each node agent a core group bridge. You might have to restart the processes again for this configuration to complete.
  3. Start the node agents. As long as two or more node agents per core group are running, the core groups can communicate.

Results

Core groups that are in the same cell can communicate and share WLM information.
