Exemples (1) - Création d’un Hub private static final String m_CDriver = "com.pointbase.jdbc.jdbcUniversalDriver"; private static final String m_CURL = "jdbc:pointbase://localhost:9092/hubdb"; private static final String m_CUser = "pbpublic"; private static final String m_CPassword = "pbpublic"; private static final String PUB = "Pub1"; private static final String HUBNAME = "Hub1"; public void configureHub2() { try { // First get an instance of the SyncManager SyncManager l_SyncManager = SyncManager.getInstance(m_CURL, m_CDriver, m_CUser, m_CPassword); // Check if the Hub already exists Hub l_Hub = l_SyncManager.getHub(HUBNAME); if(l_Hub == null) { // Create the Hub from the SyncManager l_Hub = l_SyncManager.createHub(HUBNAME); l_Hub.startServer(); } // Publish specified tables String[] tableNames = new String[]{"SCOTT.TABLE1", "SCOTT.TABLE2"}; // Check if the Publication already exists Publication l_Pub = l_Hub.getPublication(PUB); if(l_Pub == null) { // Create a new Publication l_Pub = l_Hub.newPublication(PUB, SyncDataSource.DEFAULT, tableNames); // Save the Publication l_Hub.publish(l_Pub); } } catch(Exception e) { // Handle the exception here } }

31. Exemples (2) - Création d’un Spoke private static final String m_SDriver = "com.pointbase.jdbc.jdbcUniversalDriver"; private static final String m_SURL = "jdbc:pointbase://localhost:9093/spokedb"; private static final String m_SUser = "pbpublic"; private static final String m_SPassword = "pbpublic"; private static final String PUB = "Pub1"; private static final String SUB = "Sub1"; private static final String SPOKENAME = "Spoke1"; private static final String m_HubURL = "tcp://localhost:8123"; public void configureSpoke1() { try { // First get an instance of the SyncManager SyncManager l_SyncManager = SyncManager.getInstance(m_SURL, m_SDriver, m_SUser, m_SPassword); // Check if the Spoke already exists Spoke l_Spoke = l_SyncManager.getSpoke(SPOKENAME); if(l_Spoke == null) { // Create the Spoke from the SyncManager l_Spoke = l_SyncManager.createSpoke(SPOKENAME); // Save the URL to connect to the hub l_Spoke.saveHubURL(m_HubURL); } // Subscribe to Publication PUB. This should get all the SyncTables from the Publication // Check if the Subscription already exists Subscription l_Sub = l_Spoke.getSubscription(SUB); if(l_Sub == null) { SyncDataSource l_DataSource = l_SyncManager.getSyncDataSource(SyncDataSource.DEFAULT); // Get all the tablenames from schema "SCOTT" String[] tableNames = l_DataSource.getAllTableNames("SCOTT"); // Create a new Subscription l_Sub = l_Spoke.newSubscription(SUB, SyncDataSource.DEFAULT, PUB, tableNames); // Save the Subscription l_Spoke.subscribe(l_Sub); } // Get the full snapshot from the Hub l_Spoke.getSnapshot(SUB); } catch(Exception e) { // Handle the exception here } }
