Example 26 with CacheListener

use of org.apache.geode.cache.CacheListener in project geode by apache.

the class HAClientCountEventListener method createClientCache.

public static void createClientCache(String host, Integer port1, Boolean isListenerPresent) throws Exception {
    int PORT1 = port1.intValue();
    Properties props = new Properties();
    props.setProperty(MCAST_PORT, "0");
    props.setProperty(LOCATORS, "");
    new HAConflationDUnitTest().createCache(props);
    AttributesFactory factory = new AttributesFactory();
    ClientServerTestCase.configureConnectionPool(factory, host, new int[] { PORT1 }, true, -1, -1, null);
    factory.setScope(Scope.DISTRIBUTED_ACK);
    factory.setEnableConflation(true);
    if (isListenerPresent.booleanValue() == true) {
        CacheListener clientListener = new HAClientCountEventListener();
        factory.setCacheListener(clientListener);
    }
    RegionAttributes attrs = factory.create();

Example 27 with CacheListener

use of org.apache.geode.cache.CacheListener in project geode by apache.

the class DurableClientQueueSizeDUnitTest method ackedEventsShouldBeRemovedFromTheQueueEventuallyEvenIfNoNewMessagesAreSent.

// Slows down client consumption from queue, this should cause a delay from server queue dispatch
// and receiving an ack from the client. The server should still clean up acked events from the
// queue even if no more messages are being sent. Previously events would get stuck in the queue
// if no new messages were sent because clean up was only done while sending messages
@Test
