Adding peers

The configuration distribution peer (CDP) is the primary peer in the grid. It provides a central administration point and is a workflow execution engine. The CDP houses the

Grid Manager application, which enables administrators to conduct various configuration, activation, and maintenance tasks on the grid. It can also host adapters and workflow modules, which are used by the grid to communicate with external systems. Typical grid configurations include a single CDP, although a grid can house two CDPs in high-availability (HA-CDP) mode. The CDP is added during installation.

An activity peer (AP) executes workflows. Similar to a CDP, the AP can host adapters, but it does not provide administrative services. When you add an AP to the grid, the AP automatically downloads activated workflows from the CDP to provide high-availability workflow load balancing. If a CDP becomes unavailable, the AP continues to process workflows with the other available peers in the same grid. Lightweight activity peers (LAPs) host adapters, but unlike the other peer types, they cannot execute workflows. 

Even though APs and LAPs can be added after installation, BMC recommends that you add a peer first and then install it. You can use the Grid Manager Peers tab to add peers.

To add a peer to a grid
