Hello all,
Asking why to use this parameter? Why this is set in your environment? Or even how it can hep you? Here we go:

As per Oracle documentation, this parameter is used to avoid unused sessions to be kept open in database and locking resources.
It describe in minutes how much time a client/probe can be inactive before be ended.

I recently found an environment where this parameter was too low (1 minute), potentially causing some overhead in communication only for validations. By documentation, if it’s decided to enable it, Oracle recommends value “10”.
This way, after checking and no one be aware about this parameter reason to be there, I just suppressed him from SQLNET.ORA (going back to default “0”, which is equivalent to “disabled”), so we could even reduce the network workload.
However, now we are aware that in case we have abnormal closure of clients, we can have some unused connections opened consuming resources… Not a problem at this point… 🙂
