Oracle does keep track of the number of commits and rollbacks, both on
session level and systemwide dynamically in v$sysstat and v$sesstat.
This info can be captured dynamically by various Oracle provided
tools, which are version dependent.
Statspack has been available since 8.1. It is located in $ORACLE_HOME/rdbms/admin, all files starting with sp belong to statspack.
Spauto keeps track of values at regular intervals, spreport calculates the delta between two statspack sessions.
