java.lang.Object edu.sdsc.inca.agent.ReporterManagerProxy
public class ReporterManagerProxy
Class for managing Grid proxy credentials. This class is used for 2 purposes: 1) When using remoteInvocationMethod 'globus', we use the Globus CoG API to transfer files and launch processes on a remote resource. The CoG API uses Globus services on the remote resource which needs a valid credential to authenticate. A proxy credential is a limited lifetime credential which allows you to authenticate to Globus services without typing in a password. Since a proxy has a limited lifetime and we anticipate the Reporter Agent and Reporter Manager to be long living processes, we can either create a long running proxy credential (not so good) or provide the ability to retrieve new proxy credentials from a MyProxy server. This class stores all the information to retrieve proxy credentials automatically from a MyProxy server. 2) Most likely the Reporter Managers will be executing reporters that need a valid proxy credential as part of their test, benchmark, or whatever. As with above, we need a way to refresh a proxy credential automatically. The information in this class will be passed to a remote reporter manager so that a process can be forked to retrieve new proxy credentials periodically.
