Example 3 with NodeRunner

use of org.glassfish.cluster.ssh.connect.NodeRunner in project Payara by payara.

the class NodeUtils method runAdminCommandOnNode.

/**
 * Run on admin command on a node and handle setting the message in the
 * ActionReport on an error. Note that on success no message is set in
 * the action report
 *
 * @param node  The node to run the command on. Can be local or remote
 * @param command  asadmin command to run. The list must contain all
 *                  parameters to asadmin, but not "asadmin" itself.
 * @param context   The command context. The ActionReport in this
 *                  context will be updated on an error to contain an
 *                  appropriate error message.
 * @param firstErrorMessage The first message to use if an error is
 *                          encountered. Usually something like
 *                          "Could not start instance".
 * @param humanCommand  The command the user should run on the node if
 *                      we failed to run the passed command.
 * @param output        Output from the run command.
 * @param waitForReaderThreads True: wait for the command IO to complete.
 *                      False: don't wait for IO to complete, just for
 *                      process to end.
 *                      Currently this only applies to locally run commands
 *                      and should only be set to false by start-instance
 *                      (see bug 12777).
