Managing Application Services
Use
Service management helps in centrally managing sets of services that are a part of the adaptive computing landscape.You can manage individual services or a set of services that belong to the same pool. When you manage services, you can perform the following activities:
· Display details of all the services that are a part of the adaptive computing landscape
· Execute the operations start, stop and relocate on individual services or on several services of the same pool simultaneously.
You cannot perform the relocate operation on traditionally installed services.
· Assign resources to services.
A specific resource can be assigned to the selected service, or based on the requirements of the service a resource can automatically be assigned.
· Display logs related to the operation performed on the service
