Method Detail

• start

  public void start(org.apache.uima.ducc.transport.cmdline.ICommandLine cmdLine,
           int howMany,
           String ip,
           String nodeName)
             throws Exception

  This method is used to launch multiple Agents on the same physical machine. It allows to scale up Agents on a single machine to simulate load. Each Agent instance will assume a given name and IP address.

  Parameters:

  cmdLine - - defines the command line used to exec Agent process

  howMany - - how many Agents to exec

  ip - - initial IP address to assign to first Agent instance. Subsequent Agent instances will have this IP incremented as in XXX.XXX.XXX.XX+1,XXX.XXX.XXX.XX+2, etc

  nodeName - - name of the physical machine. The Agents will be assigned this name plus a suffix as in watson-1, watson-2, etc

  Throws:

  Exception

• launchProcess

  public ManagedProcess launchProcess(NodeAgent agent,
                             org.apache.uima.ducc.common.NodeIdentity nodeIdentity,
                             org.apache.uima.ducc.transport.event.common.IDuccProcess process,
                             org.apache.uima.ducc.transport.cmdline.ICommandLine commandLine,
                             ProcessLifecycleObserver observer,
                             ManagedProcess managedProcess)
                               throws Exception

  Submit request to exec a process. The process will be exec'd in a separate thread.

  Parameters:

  process -

  commandLine -

  Throws:

  Exception

• launchProcess

  public void launchProcess(String host,
                   String ip,
                   org.apache.uima.ducc.transport.cmdline.ICommandLine cmdLine)
                     throws Exception

  This method is used to simulation only. It enables launching an agent with a given name and IP address which are different from a physical node name and IP address. With that multiple agents can be launched on the same physical machine simulating a cluster of nodes.

  Throws:

  Exception

• main

  public static void main(String[] args)
