Examples with ACTIVE_READ_ONLY org.apache.ignite.cluster.ClusterState.ACTIVE_READ_ONLY used on opensource projects

Example 1 with ACTIVE_READ_ONLY

use of org.apache.ignite.cluster.ClusterState.ACTIVE_READ_ONLY in project ignite by apache.

the class ClusterReadOnlyModeSelfTest method testEnableReadOnlyModeInsideTransaction.

/**
 */
@Test
public void testEnableReadOnlyModeInsideTransaction() throws Exception {
    IgniteEx grid = startGrids(SERVER_NODES_COUNT);
    grid.cluster().state(ACTIVE);
    CacheConfiguration cfg = Stream.of(grid.configuration().getCacheConfiguration()).filter(c -> c.getAtomicityMode() == CacheAtomicityMode.TRANSACTIONAL).filter(c -> !CU.isSystemCache(c.getName())).findAny().get();
    final int key = 1;
    IgniteCache<Integer, Integer> cache = grid.cache(cfg.getName());
    cache.put(key, 0);
    CountDownLatch startTxLatch = new CountDownLatch(1);
    CountDownLatch clusterReadOnlyLatch = new CountDownLatch(1);
    Thread t = new Thread(() -> {
        try {
            startTxLatch.await();
            grid(1).cluster().state(ACTIVE_READ_ONLY);
            assertEquals(ACTIVE_READ_ONLY, grid(1).cluster().state());
            clusterReadOnlyLatch.countDown();
        } catch (InterruptedException e) {
            log.error("Thread interrupted", e);
            fail("Thread interrupted");
        }
    });
    t.start();
    Transaction tx = grid(0).transactions().txStart();
    try {
        cache.put(key, 1);
        startTxLatch.countDown();
        tx.commit();
    } catch (Exception e) {
        log.error("TX Failed", e);
        tx.rollback();
    }
    assertEquals(1, (int) cache.get(key));
    t.join();
}

Example 2 with ACTIVE_READ_ONLY

use of org.apache.ignite.cluster.ClusterState.ACTIVE_READ_ONLY in project ignite by apache.

the class ClusterStateChangeEventTest method test.

/**

@Test
public void test() throws Exception {
    IgniteEx crd = grid(0);
    crd.cluster().state(ACTIVE);
    Map<Integer, Integer> data = IntStream.range(0, 1000).boxed().collect(Collectors.toMap(i -> i, i -> i));
    crd.cache(DEFAULT_CACHE_NAME).putAll(data);
    for (Ignite node : G.allGrids()) assertEquals(node.name(), ACTIVE, node.cluster().state());
    // ACTIVE -> READ_ONLY
    changeStateAndCheckEvents(ACTIVE_READ_ONLY);
    // READ_ONLY -> ACTIVE
