run

public void run()

Housekeeping thread. This thread runs every 30 seconds and checks connections for the following conditions:

• Connection has been open too long - it'll be closed and another connection created.
• Connection hasn't been used for 30 seconds and the number of open connections is greater than the minimum number of connections. The connection will be closed. This is done so that the pool can shrink back to the minimum number of connections if the pool isn't being used extensively.
• Unable to create a statement with the connection - it'll be reset.
