    Setting this property has no effect if getRemoveAbandonedOnBorrow() and getRemoveAbandonedOnMaintenance() are false.
    
    Parameters:
    
    removeAbandonedTimeout - new abandoned timeout in seconds
    
    See Also:
    
    getRemoveAbandonedTimeout(), getRemoveAbandonedOnBorrow(), getRemoveAbandonedOnMaintenance()
  - getLogAbandoned
```
public boolean getLogAbandoned()
```
    Flag to log stack traces for application code which abandoned a Statement or Connection.
    
    Defaults to false.
    
    Logging of abandoned Statements and Connections adds overhead for every Connection open or new Statement because a stack trace has to be generated.
    
    Specified by:
    
    getLogAbandoned in interface BasicDataSourceMXBean
    
    Returns:
    
    getLogAbandoned()
  - setLogAbandoned
```
public void setLogAbandoned(boolean logAbandoned)
```
    Parameters:
    
    logAbandoned - new logAbandoned property value
  - getAbandonedLogWriter
```
public PrintWriter getAbandonedLogWriter()
```
    Gets the print writer used by this configuration to log information on abandoned objects.
    
    Returns:
    
    The print writer used by this configuration to log information on abandoned objects.
  - setAbandonedLogWriter
```
public void setAbandonedLogWriter(PrintWriter logWriter)
```
    Sets the print writer to be used by this configuration to log information on abandoned objects.
    
    Parameters:
    
    logWriter - The new log writer
  - getAbandonedUsageTracking
```
public boolean getAbandonedUsageTracking()
```
    If the connection pool implements UsageTracking, should the connection pool record a stack trace every time a method is called on a pooled connection and retain the most recent stack trace to aid debugging of abandoned connections?
    
    Specified by:
    
    getAbandonedUsageTracking in interface BasicDataSourceMXBean
    
    Returns:
    
    true if usage tracking is enabled
  - setAbandonedUsageTracking
```
public void setAbandonedUsageTracking(boolean usageTracking)
```
    If the connection pool implements UsageTracking, configure whether the connection pool should record a stack trace every time a method is called on a pooled connection and retain the most recent stack trace to aid debugging of abandoned connections.
    
    Parameters:
    
    usageTracking - A value of true will enable the recording of a stack trace on every use of a pooled connection
  - addConnectionProperty
```
public void addConnectionProperty(String name,
                                  String value)
```
    Adds a custom connection property to the set that will be passed to our JDBC driver. This MUST be called before the first connection is retrieved (along with all the other configuration property setters). Calls to this method after the connection pool has been initialized have no effect.
    
    Parameters:
    
    name - Name of the custom connection property
    
    value - Value of the custom connection property
  - removeConnectionProperty
```
public void removeConnectionProperty(String name)
```
    Removes a custom connection property.
    
    Parameters:
    
    name - Name of the custom connection property to remove
    
    See Also:
    
    addConnectionProperty(String, String)
  - setConnectionProperties
```
public void setConnectionProperties(String connectionProperties)
```
    Sets the connection properties passed to driver.connect(...).
    Format of the string must be [propertyName=property;]*
    
    NOTE - The "user" and "password" properties will be added explicitly, so they do not need to be included here.
    
    Parameters:
    
    connectionProperties - the connection properties used to create new connections
  - close
```
public void close()
           throws SQLException
```
    Closes and releases all idle connections that are currently stored in the connection pool associated with this data source.
    
    Connections that are checked out to clients when this method is invoked are not affected. When client applications subsequently invoke Connection.close() to return these connections to the pool, the underlying JDBC connections are closed.
    
    Attempts to acquire connections using getConnection() after this method has been invoked result in SQLExceptions.
    
    This method is idempotent - i.e., closing an already closed BasicDataSource has no effect and does not generate exceptions.
    
    Specified by:
    
    close in interface AutoCloseable
    
    Throws:
    
    SQLException - if an error occurs closing idle connections
  - isClosed
```
public boolean isClosed()
```
    If true, this data source is closed and no more connections can be retrieved from this datasource.
    
    Specified by:
    
    isClosed in interface BasicDataSourceMXBean
    
    Returns:
    
    true, if the data source is closed; false otherwise
  - isWrapperFor
```
public boolean isWrapperFor(Class<?> iface)
                     throws SQLException

    Throws:

    SQLFeatureNotSupportedException
  - invalidateConnection
```
public void invalidateConnection(Connection connection)
                          throws IllegalStateException
```
    Manually invalidates a connection, effectively requesting the pool to try to close it, remove it from the pool and reclaim pool capacity.
    
    Parameters:
    
    connection - The Connection to invalidate.
    
    Throws:
    
    IllegalStateException - if invalidating the connection failed.

  - createDataSource
```
protected DataSource createDataSource()
                               throws SQLException
```
    Creates (if necessary) and return the internal data source we are using to manage our connections.
    
    Throws:
    
    SQLException - if the object pool cannot be created.
  - createConnectionFactory
```
protected ConnectionFactory createConnectionFactory()
                                             throws SQLException
```
    Creates a JDBC connection factory for this datasource. The JDBC driver is loaded using the following algorithm:
    1. If a Driver instance has been specified via setDriver(Driver) use it
    2. If no Driver instance was specified and driverClassName is specified that class is loaded using the ClassLoader of this class or, if driverClassLoader is set, driverClassName is loaded with the specified ClassLoader.
    3. If driverClassName is specified and the previous attempt fails, the class is loaded using the context class loader of the current thread.
    4. If a driver still isn't loaded one is loaded via the DriverManager using the specified url.
    This method exists so subclasses can replace the implementation class.
    Throws:
    
    SQLException
  - createConnectionPool
```
protected void createConnectionPool(PoolableConnectionFactory factory)
```
    Creates a connection pool for this datasource. This method only exists so subclasses can replace the implementation class.
    This implementation configures all pool properties other than timeBetweenEvictionRunsMillis. Setting that property is deferred to startPoolMaintenance(), since setting timeBetweenEvictionRunsMillis to a positive value causes GenericObjectPool's eviction timer to be started.
  - createObjectPool
```
protected GenericObjectPool<PoolableConnection> createObjectPool(PoolableConnectionFactory factory,
                                                                 GenericObjectPoolConfig poolConfig,

```
    Creates an object pool used to provide pooling support for JDBC connections.
    
    Parameters:
    
    factory - the object factory
    
    poolConfig - the object pool configuration
    
    abandonedConfig - the abandoned objects configuration
    
    Returns:
    
    a non-null instance
  - startPoolMaintenance
```
protected void startPoolMaintenance()
```
    Starts the connection pool maintenance task, if configured.
  - createDataSourceInstance
```
protected DataSource createDataSourceInstance()
                                       throws SQLException
```
    Creates the actual data source instance. This method only exists so that subclasses can replace the implementation class.
    
    Throws:
    
    SQLException - if unable to create a datasource instance
  - createPoolableConnectionFactory
```
protected PoolableConnectionFactory createPoolableConnectionFactory(ConnectionFactory driverConnectionFactory)
                                                             throws SQLException
```
    Creates the PoolableConnectionFactory and attaches it to the connection pool. This method only exists so subclasses can replace the default implementation.
    
    Parameters:
    
    driverConnectionFactory - JDBC connection factory
    
    Throws:
    
    SQLException - if an error occurs creating the PoolableConnectionFactory
  - validateConnectionFactory
