Example 6 with Semaphore

use of nl.nn.adapterframework.util.Semaphore in project iaf by ibissource.

the class JdbcTableListenerTest method testParallelChangeProcessState.

public void testParallelChangeProcessState(boolean mainThreadFirst) throws Exception {
    listener.configure();
    listener.open();
    JdbcUtil.executeStatement(dbmsSupport, connection, "DELETE FROM TEMP WHERE TKEY=10", null);
    JdbcUtil.executeStatement(dbmsSupport, connection, "INSERT INTO TEMP (TKEY,TINT) VALUES (10,1)", null);
    ChangeProcessStateTester changeProcessStateTester = new ChangeProcessStateTester(() -> getConnection());
    Object rawMessage1;
    Semaphore waitBeforeUpdate = new Semaphore();
    Semaphore updateDone = new Semaphore();
    Semaphore waitBeforeCommit = new Semaphore();
    Semaphore commitDone = new Semaphore();
    try (Connection conn = getConnection()) {
        conn.setAutoCommit(false);
        try {
            changeProcessStateTester.setWaitBeforeAction(waitBeforeUpdate);

Example 7 with Semaphore

use of nl.nn.adapterframework.util.Semaphore in project iaf by ibissource.

the class PullingListenerContainer method configure.

public void configure() {
    if (receiver.getNumThreadsPolling() > 0 && receiver.getNumThreadsPolling() < receiver.getNumThreads()) {
        pollToken = new Semaphore(receiver.getNumThreadsPolling());
    }
    processToken = new Semaphore(receiver.getNumThreads());
    maxThreadCount = receiver.getNumThreads();
    if (receiver.getTransactionAttribute() != TransactionAttribute.NOTSUPPORTED) {
        DefaultTransactionDefinition txDef = new DefaultTransactionDefinition(TransactionAttribute.REQUIRESNEW.getTransactionAttributeNum());
        if (receiver.getTransactionTimeout() > 0) {
            txDef.setTimeout(receiver.getTransactionTimeout());
        }
        txNew = txDef;
    }
}
