Interface UniversalConnectionPoolManagerMBean


public interface UniversalConnectionPoolManagerMBean

The Universal Connection Pool Manager MBean defines operations and attributes for managing pool instances. Remote users can get access to these operations and attributes using JMX operations. The MBean has access to the Universal Connection Pool Manager and gets the required pool object to start an operation.

There is only one Universal Connection Pool Manager MBean for a JVM and this is registered with an MBeanServer.

All the operations implemented on the pool manager MBean are called only when jmxFlag on the pool manager is set to true. Default value for jmxFlag is true. When the MBeanServer is not available, jmxFlag is automatically set to false.

Method Detail

startConnectionPool

void startConnectionPool(java.lang.String poolName)
                         throws UniversalConnectionPoolException
Starts the connection pool. A connection pool object is obtained from the manager by providing poolname as a key. Pool operation is called to start the connection pool.

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 to find the connection pool object from 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 poolname as a 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 a key. Pool operation is called to refresh the connection pool.
Parameters:
String - Connection pool name to find the connection pool object from the 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 a 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 the 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 a 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:
String - Connection pool name to find the connection pool object from the pool manager.
Throws:
UniversalConnectionPoolException - If an error occurs while purging the connection pool.

createConnectionPool

UniversalConnectionPoolMBean 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. Connection pool object is obtained from the manager by providing poolname as a key. Pool operation is called to stop the connection pool. The pool is 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.

getConnectionPoolNames

Returns:
String[] List of connection pool Names, returned as an Array.
Throws:
UniversalConnectionPoolException - If an error occurs while getting the pool names.

UniversalConnectionPoolException - If an error occurs while updating metric interval.

getMetricUpdateInterval

int getMetricUpdateInterval()
Gets the metric update interval value.
