SQL*Net message from client
Short Description
The server process (foreground process) waits for a message from the client process to arrive.
Detailed Description​
Usually the SQL*Net message from client event is an idle event where the database is waiting to be asked to do something.
How to reduce this wait​
This wait event is not usually indicative of an issue, as it can just be a user session waiting for someone to type the next command, but if the wait time increases rapidly, it can be a sign of connections being opened and not being closed/terminated in a timely fashion.
