When you configure an application service, you designate a node to run the service process. When a service process runs, the Service Manager assigns a port number from the range of port numbers assigned to the node.
The service process is the runtime representation of a service running on a node. The service type determines how many service processes can run at a time. For example, the PowerCenter Integration Service can run multiple service processes at a time when you run it on a grid.
If you have the high availability option, you can run a service on multiple nodes. Designate the primary node to run the service. All other nodes are back-up nodes for the service. If the primary node is not available, the service runs on a back-up node. You can subscribe to alerts to receive notification in the event of a service process failover.
If you do not have the high availability option, configure a service to run on one node. If you assign the service to multiple nodes, then the service will not start.
