Examples with FileMoveManager org.apache.activemq.artemis.core.server.files.FileMoveManager used on opensource projects

Example 1 with FileMoveManager

use of org.apache.activemq.artemis.core.server.files.FileMoveManager in project activemq-artemis by apache.

the class ActiveMQServerImpl method moveServerData.

/**
 * Move data away before starting data synchronization for fail-back.
 * <p>
 * Use case is a server, upon restarting, finding a former backup running in its place. It will
 * move any older data away and log a warning about it.

    File[] dataDirs = new File[] { configuration.getBindingsLocation(), configuration.getJournalLocation(), configuration.getPagingLocation(), configuration.getLargeMessagesLocation() };
    for (File data : dataDirs) {
        FileMoveManager moveManager = new FileMoveManager(data, maxSavedReplicated);
        moveManager.doMove();
