Interface UniversalConnectionPoolManager

  • All Known Implementing Classes:
    oracle.ucp.admin.UniversalConnectionPoolManagerBase, UniversalConnectionPoolManagerImpl
    public interface UniversalConnectionPoolManager
    The UniversalConnectionPoolManager interface defines operations for creating and maintaining the Universal Connection Pool instances. A pool instance is registered with the pool manager every time a new pool is created. All the pool operations can be called by providing the pool name as a key. Operations for controlling the metric collection for individual Universal Connection Pool instances are also provided.

    The jmxFlag property on UniversalConnectionPoolManager determines the availability of JMX support. The default value for jmxFlag is true. The jmxFlag property is automatically set to false when the MBeanServer is not available.

    • Method Detail

      • startConnectionPool

        void startConnectionPool​(java.lang.String poolName)
                  throws UniversalConnectionPoolException
        Starts the connection pool instance with the given name.

        Starting the pool does not start metric collection for the pool. Operation startMetricsCollection needs to be called to start the metric collection for the pool.

        Parameters:
        poolName - Connection pool name for identifying the pool instance registered with the pool manager.
        Throws:
        UniversalConnectionPoolException - If an error occurs while starting the connection pool.

      • stopConnectionPool

        void stopConnectionPool​(java.lang.String poolName)
                 throws UniversalConnectionPoolException
        Stops the connection pool. Connection pool object is obtained from the manager by providing pool name as key. Pool operation is called to stop the connection pool. Stops the metric collection if it is already started.
        Parameters:
        poolName - Connection pool name to find the connection pool object from the pool manager.
        Throws:
        UniversalConnectionPoolException - If an error occurs while stopping the connection pool.

      • refreshConnectionPool

        void refreshConnectionPool​(java.lang.String poolName)
                    throws UniversalConnectionPoolException
        Refreshes the connection pool. Connection pool object is obtained from the manager by providing poolname as key. Pool operation is called to refresh the connection pool.
        Parameters:
        poolName - Connection pool name to find the connection pool object from pool manager.
        Throws:
        UniversalConnectionPoolException - If an error occurs while refreshing the connection pool.

      • recycleConnectionPool

        void recycleConnectionPool​(java.lang.String poolName)
                    throws UniversalConnectionPoolException
        Recycles the connection pool. Connection pool object is obtained from the manager by providing poolname as key. Pool operation is called to recycle the connection pool. This is similar to refresh(), but allows only invalid available connections in the pool to be replaced with new/fresh connections.
        Parameters:
        poolName - Connection pool name to find the connection pool object from pool manager.
        Throws:
        UniversalConnectionPoolException - If an error occurs while recycling the connection pool.

      • purgeConnectionPool

        void purgeConnectionPool​(java.lang.String poolName)
                  throws UniversalConnectionPoolException
        Purges the connection pool. Connection pool object is obtained from the manager by providing poolname as key. Pool operation is called to purge the connection pool.

        Removes all connections from the connection pool. The primary difference in behavior between this and refresh() is that the connection pool is left empty with no connections available after calling purge(). Some of the connection pool properties such as minPoolSize or initialPoolSize may not be honored when purging connections from the pool.

        Parameters:
        poolName - Connection pool name to find the connection pool object from pool manager.
        Throws:
        UniversalConnectionPoolException - If an error occurs while purging the connection pool.

      • createConnectionPool

        void createConnectionPool​(UniversalConnectionPoolAdapter ucpAdapter)
                   throws UniversalConnectionPoolException
        Creates a connection pool instance based on specified UCP Adapter. Pool and connection factory configuration properties should be set on the Adapter prior to invoking this method. The created pool instance will be added to this UCP manager.
        Parameters:
        ucpAdapter - The UCP Adapter for pool creation.
        Throws:
        UniversalConnectionPoolException - If an error occurs while creating the connection pool.

      • destroyConnectionPool

        void destroyConnectionPool​(java.lang.String poolName)
                    throws UniversalConnectionPoolException
        Destroys the connection pool. The connection pool is obtained from the manager by providing poolname as key. Pool operation is called to stop the connection pool. Pool will be stopped and removed from the manager.
        Parameters:
        poolName - Connection pool name to find the connection pool object from the pool manager.
        Throws:
        UniversalConnectionPoolException - If an error occurs while destroying the connection pool.

      • reconfigureConnectionPool

                               java.util.Properties configuration)
                        throws UniversalConnectionPoolException
