It leads to - No managed connections available.  During the application run-time, I need to flush the pool using Console. I have tried with ojdbc14 and ojdbc6 drivers also.  My application uses nearly 11 data sources.  This application and their data sources were absolutely fine with Weblogic 10.3.5. Eventually, I should move towards to managed nodes later.

AS 7.2.0 standalone deployment

Min-Pool Size =30; Max-Pool Size=100 with Prefil=false.

spy is not yielding to any conclusion.

I believe there should be some mechanism manage the connection pool automatically.

Thanks
