Home -> Community -> Mailing Lists -> Oracle-L -> RE: Wait event problems
I would add that the Statspack's Top 5 events miss out other SQL*Net related
waits. Those can not be ignored in the client/server type environments.
I fiddle with the perfstat.stats$idle_event table that contains a list of such 'idle' events. The events in this table are never reported by statspack in the 'Top 5' category. And that can be misleading.

This is never an "idle" event. The phrase "more data from client" indicates that the individual SQL operation is larger than a single SQL*Net packet. No big deal; it happens all the time, and SQL*Net handles it with "continuation packets". Only issue is that the client is taking a lot of time between each packet sent. Jack's conclusion that the client process (in the "client-server" database connection) is not providing data in a "timely fashion" is exactly correct. You most likely have a slow client process...
Oracle documentation frequently tries to encourage mucking about with SDU/TDU parameters in SQL*Net configuration files, but I've rarely seen this be more effective than tuning the client process... :-)
