Interface XADataSource

  • All Superinterfaces:
    CommonDataSource


    public interface XADataSource
    extends CommonDataSource
    A factory for XAConnection objects that is used internally. An object that implements the XADataSource interface is typically registered with a naming service that uses the Java Naming and Directory Interface™ (JNDI).

    An implementation of XADataSource must include a public no-arg constructor.

      • getXAConnection

        XAConnection getXAConnection​()
                              throws SQLException
        Attempts to establish a physical database connection that can be used in a distributed transaction.
        Returns:
        an XAConnection object, which represents a physical connection to a data source, that can be used in a distributed transaction
        Throws:
        SQLException - if a database access error occurs
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method
        SQLTimeoutException - when the driver has determined that the timeout value specified by the setLoginTimeout method has been exceeded and has at least tried to cancel the current database connection attempt

      • getXAConnection

        XAConnection getXAConnection​(String user,
                                     String password)
                              throws SQLException
        Attempts to establish a physical database connection, using the given user name and password. The connection that is returned is one that can be used in a distributed transaction.
        Parameters:
        user - the database user on whose behalf the connection is being made
        password - the user's password
        Returns:
        an XAConnection object, which represents a physical connection to a data source, that can be used in a distributed transaction
        Throws:
        SQLException - if a database access error occurs
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method
        SQLTimeoutException - when the driver has determined that the timeout value specified by the setLoginTimeout method has been exceeded and has at least tried to cancel the current database connection attempt

      • getLogWriter

        PrintWriter getLogWriter​()
                          throws SQLException

        Retrieves the log writer for this DataSource object.

        The log writer is a character output stream to which all logging and tracing messages for this data source will be printed. This includes messages printed by the methods of this object, messages printed by methods of other objects manufactured by this object, and so on. Messages printed to a data source specific log writer are not printed to the log writer associated with the java.sql.DriverManager class. When a DataSource object is created, the log writer is initially null; in other words, the default is for logging to be disabled.

        Specified by:
        getLogWriter in interface CommonDataSource
        Returns:
        the log writer for this data source or null if logging is disabled
        Throws:
        SQLException - if a database access error occurs

      • setLogWriter

        void setLogWriter​(PrintWriter out)
                   throws SQLException

        Sets the log writer for this DataSource object to the given java.io.PrintWriter object.

        The log writer is a character output stream to which all logging and tracing messages for this data source will be printed. This includes messages printed by the methods of this object, messages printed by methods of other objects manufactured by this object, and so on. Messages printed to a data source- specific log writer are not printed to the log writer associated with the java.sql.DriverManager class. When a DataSource object is created the log writer is initially null; in other words, the default is for logging to be disabled.

        Specified by:
        setLogWriter in interface CommonDataSource
        Parameters:
        out - the new log writer; to disable logging, set to null
        Throws:
        SQLException - if a database access error occurs

      • setLoginTimeout

        void setLoginTimeout​(int seconds)
                      throws SQLException

        Sets the maximum time in seconds that this data source will wait while attempting to connect to a database. A value of zero specifies that the timeout is the default system timeout if there is one; otherwise, it specifies that there is no timeout. When a DataSource object is created, the login timeout is initially zero.

        Specified by:
        setLoginTimeout in interface CommonDataSource
        Parameters:
        seconds - the data source login time limit
        Throws:
        SQLException - if a database access error occurs.

      • getLoginTimeout

        int getLoginTimeout​()
                     throws SQLException
        Gets the maximum time in seconds that this data source can wait while attempting to connect to a database. A value of zero means that the timeout is the default system timeout if there is one; otherwise, it means that there is no timeout. When a DataSource object is created, the login timeout is initially zero.
        Specified by:
        getLoginTimeout in interface CommonDataSource
        Returns:
        the data source login time limit
        Throws:
        SQLException - if a database access error occurs.

      • createXAConnectionBuilder

        default XAConnectionBuilder createXAConnectionBuilder​()
                                                       throws SQLException
        Creates a new XAConnectionBuilder instance
        Implementation Requirements:
        The default implementation will throw a SQLFeatureNotSupportedException.
        Returns:
        The XAConnectionBuilder instance that was created
        Throws:
        SQLException - if an error occurs creating the builder
        SQLFeatureNotSupportedException - if the driver does not support sharding
