Bryan,

 

You can run=20 statspack snapshots every hour, then run reports comparing each = hourly=20 snapshot and it will show you the transactions/sec in the top "Load"=20 section.  No init setting required for this, but you'll want=20 timed_statistics=3Dtrue in order to gather other useful=20 stats.
