Intégration Bitronix avec chauffeur JTDS

Question

Je suis en train d'exécuter un PoolingDataSource avec le pilote JTDS pour SQL Server et Sybase connexions.

protected DataSource dataSource() throws Exception { 
    // Create pool datasource 
    final PoolingDataSource poolingDataSource = new PoolingDataSource(); 
    poolingDataSource.setClassName("bitronix.tm.resource.jdbc.lrc.LrcXADataSource"); 
    poolingDataSource.setMaxPoolSize(20); 
    poolingDataSource.setUniqueName(getDataSourceProperty().getUserName()); 
    poolingDataSource.setAllowLocalTransactions(true); 
    poolingDataSource.setAutomaticEnlistingEnabled(true); 
    poolingDataSource.setShareTransactionConnections(false); 

    final Properties properties = new Properties(); 
    properties.put("driverClassName", getDataSourceProperty().getDriverClassName()); 
    properties.put("url", getDataSourceProperty().getUrl()); 
    properties.put("user", getDataSourceProperty().getUserName()); 
    properties.put("password", DataSourceSecureIdentity.decode(getDataSourceProperty().getPassword())); 

    poolingDataSource.setDriverProperties(properties); 

    return poolingDataSource; 
} 

Une fois que le serveur est démarré il montre:

Caused by: bitronix.tm.internal.BitronixSystemException: cannot enlist more than one non-XA resource, tried enlisting an XAResourceHolderState with uniqueName=xxx XAResource=a JDBC LrcXAResource in state NO_TX with XID null, already enlisted: an XAResourceHolderState with uniqueName=xxx2 XAResource=a JDBC LrcXAResource in state STARTED (started) with XID a Bitronix XID [7465737465000000001757A2D000000005 : 7465737465000000001757A70A00000006]

Je lis, je ne peux pas avoir une source de données non-XA, mais si la classe LrcXADataSource est enveloppait la source de données pourquoi se fait-il?

Est-il possible d'informer JTDS pilote sur l'option XA?

Answer 1

J'ai découvert qu'émuler une source de données XA via LrcXADataSource et l'insérer dans un pool XA via PoolingDataSourceBean Je peux avoir plusieurs sources de données non-XA fonctionnant sur Bitronix.

protected DataSource dataSource() throws Exception { 
    // Create XA datasource 
    final LrcXADataSource lrcXADataSource = new LrcXADataSource(); 
    lrcXADataSource.setDriverClassName(getDataSourceProperty().getDriverClassName()); 
    lrcXADataSource.setUrl(getDataSourceProperty().getUrl()); 
    lrcXADataSource.setUser(getDataSourceProperty().getUserName()); 
    lrcXADataSource.setPassword(DataSourceSecureIdentity.decode(getDataSourceProperty().getPassword())); 

    // Create a pool of XA datasource 
    final PoolingDataSourceBean poolingDataSourceBean = new PoolingDataSourceBean(); 
    poolingDataSourceBean.setDataSource(lrcXADataSource); 
    poolingDataSourceBean.setMaxPoolSize(getDataSourceProperty().getMaxPoolSize()); 
    poolingDataSourceBean.setMinPoolSize(getDataSourceProperty().getMinPoolSize()); 
    poolingDataSourceBean.setTestQuery(getDataSourceProperty().getValidationQuery()); 

    return poolingDataSourceBean; 
}
