Examples of com.sun.faban.harness.engine.CmdService

com.sun.faban.harness.engine.CmdService
This file contains the class that implements the Command service API. The Command Service object is created by the Engine at the start of a run and it starts up the CmdAgent applications on all the machines and connects to them via RMI. In the API implementation, it identifies the particular CmdAgent and passes the call along. The CmdAgents take care of any error messages generated by the command and automatically log them to the run's error log. The CmdAgent's path will include the default faban bin directories (in addition to /usr/bin, /usr/sbin, /usr/ucb), so any faban executables will be found. Commands in any other path should be invoked with the full pathname of the command. The CmdAgent's environment will also include CLASSPATH set to the faban lib directory to find any Java classes. Shell commands or any commands whose output must be re-directed or piped (basically using shell) should be executed using syntax such as : "sh -c [] [> out]". IMPORTANT: There should be a single CmdService object in the entire framework or else multiple copies of the CmdAgent application will be spawned on the target machines. Therefore, this class is implemented as a Singleton. No public constructors are defined and the object cannot be cloned. @author Ramesh Ramachandran @see com.sun.faban.harness.agent.CmdAgent @see com.sun.faban.harness.engine.GenericBenchmark
