Direct Oracle Access Object Single user with Oracle Monitor Pro (USD 50/License)

includes Oracle Monitor Pro

The Pro version displays network and server statistics (network roundtrips, network bytes sent/received, CPU time, physical I/O, logical I/O, table scans, index scans, records fetched, ...) for each activity. If the activity is a select, insert, update or delete statement, you can also view the query execution plan, and modify the SQL to see the effects this has.
