Re: Help on wait event SQL*Net message from client

Generally SQL*Net message from client means Oracle is just waiting on something to do; you have a session connected and Oracle is waiting for a command so it can do something. If you're thinking that this is the cause of a performance issue, there's likely another underlying issue such as the application connecting but not running any statements (which is not an Oracle issue but would appear to the end user as a performance problem), or you're looking in the wrong place for the source of the problem.

What type of report or query are you using that indicates this is a problem?
