Subject Re: Cayenne Connection Pool Monitoring - to solve "out of connections" error
Date Wed, 12 May 2010 16:30:29 GMT

My original question was how can I query the Cayenne Connection Pool Manger to find out how
many connections are currently open and how many are currently closed?

Is there a way to do this via the Cayenne API?  (If there is I have not been able to determine
how to access the PoolManager from the DataContext, or whatever means is available.)

I would like to start with the standard API first if possible.
