MinChen Chai has created Keep-Alive Extension exactly for your situation: https://sites.google.com/site/keepaliveext

It will continually send TCP keep-alive packets and prevent server disconnection by inactivity timeout.

DISCLAIMER: I'm the developer of the extension. I hope the answer is not considered advertising, because this extension is open source (and the previous non-open-source extensions were accepted as an answer).

Answer 5

When used with the latest SQL Developer Version 4.0.0.13:
- MinChen's extension (http://sites.google.com/site/keepaliveext) doesn't work.
- The keepconnext extension (http://sites.google.com/site/keepconnext) too doesn't work anymore.

Answer 6

As the suggested extensions in this thread have had issues with recent versions of SQL Developer, I tried my way and got scristalli's code to work in a new project based on his code AND the oracle example repo.

Needs a lot of work but oh well, at least I can install the new build on SQLDev v19.2 and it works as expected.
