Groovy script to quiesce a CRX/CQ instance

quiesce.groovy

import javax.management.remote.JMXServiceURL;
import javax.management.remote.JMXConnectorFactory;
import javax.management.ObjectName;

// assuming that CQ is started with -Dcom.sun.management.jmxremote.port=9000

def jmxUrl = "service:jmx:rmi:///jndi/rmi://localhost:9000/jmxrmi";
def serviceUrl = new JMXServiceURL(jmxUrl);
def jmxConnector = JMXConnectorFactory.connect(serviceUrl);
def mbeanConn = jmxConnector.getMBeanServerConnection();
def repositoryName = new ObjectName("com.adobe.granite:type=Repository");

mbeanConn.invoke(repositoryName, "blockRepositoryWrites", new Object[0], new String[0]);

System.out.println("The System is now quiesced.");
