PowerCenter Repository Service and Service Processes
PowerCenter Repository Service and Service Processes
When you enable a PowerCenter Repository Service, a service process starts on a node designated to run the service. The service is available to perform repository transactions. If you have the high availability option, the service can fail over to another node if the current node becomes unavailable. If you disable the PowerCenter Repository Service, the service cannot run on any node until you reenable the service.
When you enable a service process, the service process is available to run, but it may not start. For example, if you have the high availability option and you configure a PowerCenter Repository Service to run on a primary node and two backup nodes, you enable PowerCenter Repository Service processes on all three nodes. A single process runs at any given time, and the other processes maintain standby status. If you disable a PowerCenter Repository Service process, the PowerCenter Repository Service cannot run on the particular node of the service process. The PowerCenter Repository Service continues to run on another node that is designated to run the service, as long as the node is available.
