public ConnectionMonitorImpl()

Method Detail

initialize

public void initialize(ConnectionPool pool)

Description copied from interface: ConnectionMonitor

Initializes the monitor, called after the manager has been started up.

Specified by:

initialize in interface ConnectionMonitor

Parameters:

pool - Instance of connection pool

connectionCreated

public void connectionCreated(PooledConnection connection,
                              long duration)

Description copied from interface: ConnectionMonitor

Notifies creation of connection. Upon notification connection is considered pending, not yet reserved.

Specified by:

connectionCreated in interface ConnectionMonitor

Parameters:

connection - PooledConnection

duration - Duration of operation, in milliseconds

connectionReserved

public void connectionReserved(PooledConnection connection,
                               long duration)

Description copied from interface: ConnectionMonitor

Notifies reservation of connection immediately after operation has been performed.

Specified by:

connectionReserved in interface ConnectionMonitor

Parameters:

connection - PooledConnection

duration - Duration of operation, in milliseconds

connectionAcquireTimedout

public void connectionAcquireTimedout(ConnectionPool pool,
                                      long duration)

Description copied from interface: ConnectionMonitor

Notifies unsuccessful attempt to acquire connection. Maximum timeout for acquire operation has been exceed.

Specified by:

connectionAcquireTimedout in interface ConnectionMonitor

Parameters:

pool - ConnectionPool

duration - Duration of operation, in milliseconds

connectionReleased

public void connectionReleased(PooledConnection connection)

Description copied from interface: ConnectionMonitor

Notifies release of connection immediately after operation has been performed.

Specified by:

connectionReleased in interface ConnectionMonitor

Parameters:

connection - PooledConnection

connectionClosed

public void connectionClosed(PooledConnection connection)

Description copied from interface: ConnectionMonitor

Notifies that connection is being closed, because maximum lifetime has been exceeded or java.sql.Connection instance has been expliticly closed (for instance with java.sql.Connection.close()).

Specified by:

connectionClosed in interface ConnectionMonitor

Parameters:

connection - PooledConnection

connectionTimeout

public void connectionTimeout(PooledConnection connection)

Description copied from interface: ConnectionMonitor

Notifies that the maximum reservation time of connection has been exceed. Thus the reserving thread is considered dead and connection has been a subject to forced shutdown.

Specified by:

connectionTimeout in interface ConnectionMonitor

Parameters:

connection - PooledConnection

connectionException

public void connectionException(java.lang.String source,
                                java.lang.Exception exception)

Description copied from interface: ConnectionMonitor

Notifies exception situation.

Specified by:

connectionException in interface ConnectionMonitor

Parameters:

source - Informative source name (class.method)

exception - Exception that occured

printStatus

public void printStatus(java.lang.String operation,
                        ConnectionPool pool,
                        long duration)

printStatus

public void printStatus(java.lang.String operation,
                        PooledConnection conn,
                        long duration)
