When win10 uses plsql to connect to the database on the local area network, what if after a period of time (30 minutes? If you do not operate, you will "not respond" when you do it again.

sometimes it gets stuck. What if I keep plsql connected all the time?
other methods on the Internet have been tried and have not worked
