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. <p/> 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. <p/> 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:

String - 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:

String - 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:

String - 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:

String - 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. <p/> 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:

String - 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:

UniversalConnectionPoolAdapter - 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:

String - Connection pool name to find the connection pool object from the pool manager.

Throws:

UniversalConnectionPoolException - If an error occurs while destroying the connection pool.

setConnectionPool

void setConnectionPool(UniversalConnectionPool connectionPool)
                       throws UniversalConnectionPoolException

Sets the Universal Connection Pool with the UniversalConnectionPoolManager Object. Once the pool is stored, it can be maintained with the operations provided on the pool manager.

Parameters:

UniversalConnectionPool - The UniversalConnectionPool object to be maintained by the Universal Connection Pool Manager.

Throws:

UniversalConnectionPoolException - If an error occurs while storing the UniversalConnectionPool object with the Universal Connection Pool Manager.

getConnectionPool
