Depending on the application, couldn't these large pauses be performance problems in the client program? Not a server tuning issue nor a SQL*Net tuning issue at all? For example, if the client program was pausing a long time between FETCH commands, processing previously fetched data? Or would that just be accounted for under "SQL*Net message from client" events?

Hi,

I am tuning a system at a client site and notice lots of waits for SQL*Net more data to client (97%) for a fraction

of the CPU consumed by the system.

I know this is not to be characterized as an idle wait event and can yield better performance if we increase

the packet size.

The database is Oracle 7.3.4 (SQL Net 2.3). What effect will increasing TDU and SDU have

on this wait to increase packet size.

It seems that if we can reduce this wait then we can save lots of time (I Think).

Will using BEQ protocol help at all.

Regards

Suhen
