This is not a problem. Sessions with a status of INACTIVE in V$SESSION just means they are not currently running a query. When the session is running a query it will go to ACTIVE, then back to INACTIVE when the query finishes.

Experts,
Thanks for quick response. my problem is here why the sessions are in inactive even though it is not doing any activity in the DB. why session are not closing automatically after query execution is completed.?
at db side no chance to time out those sessions. we have allocated unlimited resource to that user account which are making session in the db.
can any one help me to find why the sessions are being inactive and not flushing out from db.

A session wouldn't close automatically when a query completes. Coding an application to connect, run one query and disconnect is very inefficient. A lot of time will be spent connecting to the database.

do you think this these inactive session are inactive due to connection is not made to oracle in proper time?
i did not understand your explanation. could you please clarify me once again.

Normally, an application would do this:
- connect
- run a query
- wait for user input <- Connection would show as INACTIVE here
- run a query
- wait for user input <- Connection would show as INACTIVE here
- .....
- disconnect
It should not do this:
- connect
- run a query
- disconnect
- connect
- run a query
- disconnect
- connect
- run a query
- wait for user input <- Connection would show as INACTIVE here
- run a query
- wait for user input <- Connection would show as INACTIVE here
- .....
- disconnect
It should not do this:
- connect
- run a query
- disconnect
- connect
- run a query
- disconnect

V$SESSION_WAIT will tell you what the session is waiting for. It will most likely be SQL Net message from client, or something similar.
