public PooledConnectionQueue(DataSourcePool pool)

Method Detail

toString

public String toString()

Overrides:

toString in class Object

reportClosingConnection

protected void reportClosingConnection(PooledConnection pooledConnection)

Collect statistics of a connection that is fully closing

getStatistics

public DataSourcePoolStatistics getStatistics(boolean reset)

getStatus

public DataSourcePool.Status getStatus(boolean reset)

setMinSize

public void setMinSize(int minSize)

setMaxSize

public void setMaxSize(int maxSize)

setWarningSize

public void setWarningSize(int warningSize)

ensureMinimumConnections

public void ensureMinimumConnections()
                              throws SQLException

Throws:

SQLException

returnPooledConnection

protected void returnPooledConnection(PooledConnection c,
                          boolean forceClose)

Return a PooledConnection.

getPooledConnection

public PooledConnection getPooledConnection()
                                     throws SQLException

Throws:

SQLException

shutdown

public void shutdown()

reset

public void reset(long leakTimeMinutes)

Close all the connections in the pool and any current busy connections when they are returned. New connections will be then created on demand.

This is typically done when a database down event occurs.

trim

public void trim(long maxInactiveMillis,
        long maxAgeMillis)

closeFreeConnections

public void closeFreeConnections(boolean logErrors)

Close all the connections that are in the free list.

closeBusyConnections

public void closeBusyConnections(long leakTimeMinutes)

Close any busy connections that have not been used for some time.

These connections are considered to have leaked from the connection pool.

Connection leaks occur when code doesn't ensure that connections are closed() after they have been finished with. There should be an appropriate try catch finally block to ensure connections are always closed and put back into the pool.

getBusyConnectionInformation

public String getBusyConnectionInformation()

dumpBusyConnectionInformation

public void dumpBusyConnectionInformation()
