Re: PGA_AGGREGATE_TARGET, AUTO PGA TARGET and WORKAREA_SIZE_POLICY

Interesting. I have good experiences with pooled connections. As for the inactive process killer, I usually do that by setting the resource limit for the idle time, like described here:

https://docs.oracle.com/database/121/SQLRF/statements_6012.htm#SQLRF01310

With the pooled connection, disconnection results in returning the server to the pool. I definitely agree that for OLTP applications, inactive sessions should be killed after relatively short time of inactivity, like 15 minutes or so. Sometimes 3rd party applications are written in such a way that screen forms are populated by using "select for update", which can have interesting consequences if the person operating the session goes to a meeting or takes a lunch break.

We have an idle process killer. Some days it's very active. Other days are not very active. It's third party stuff so we can't see what they are doing.
