Rollback per transaction %:73 %?

Folks

Is "Rollback per transaction %: 73.06" under "Load Profile" section of AWR Report abnormally High? .., If so, what does this imply? .. How is the issue to be approached?

NOTE - This was observed during a Benchmark run of a Banking Java Application using Oracle thin driver to connect to the Database. Dedicated Server process connections to Database. OLTP Nature of Transactions

Cheers & Advice pls

Vivek
