we have to use denodo connect the oracle db to retrieve some data. but recently, we find the connection
often occur timeout. we checked the interaction between 2 servers and it's ok.
sometimes, i open a admin tool to run some sql demo in the denodo server
when i firstly open the denodo admin tool, the sql run normally, but if i stay away for a while,
then back, i try to run the SQL again, it will be timeout. and our web application will be timeout too
