Close pool being maintained by this datasource. | | public int | getMaxActive()
The maximum number of active connections that can be allocated from
this pool at the same time, or non-positive for no limit. | | public int | getMaxIdle()
The maximum number of active connections that can remain idle in the
pool, without extra ones being released, or negative for no limit. | | public int | getMaxWait()
The maximum number of milliseconds that the pool will wait (when there
are no available connections) for a connection to be returned before
throwing an exception, or -1 to wait indefinitely. | | public int | getNumActive()
Get the number of active connections in the pool. | | public int | getNumIdle()
Get the number of idle connections in the pool. | | protected synchronized PooledConnectionAndInfo | getPooledConnectionAndInfo(String username, String password)

pool, without extra ones being released, or negative for no limit. | | public void | setMaxWait(int maxWait)
