APEX

I have an applicatiion which queries from bugDB using a Dblink. There are an items in page which are entered/selected, that go as input into a query associated with the resion. When I submit, query get executed and records are displayed. When I do this selection/execution a few times SESSION_PER_USER limit get execeeded message is displayed.

I think every time a query is getting executed there is a database session which gets created and this gets execeeded. I have to wait for some time, before presumably a background process clears the connection. I tried logging out or closing browser. It did not help much.

I am not sure of the solution!
Is there a way everytime II exceucte a query, I close the session including the database conenction in the background and then restart a new session. Experts please help out!
