The TPC-C benchmark, as I was given to understand, runs 4 of its 5 transactions using the Repeatable Read isolation level and the fifth (the stocklevel transaction) using the Cursor Stability isolation level. Repeatable Read implies row locks are held until a commit point is encountered. I don't really know what Oracle supports as regards row locking. Could someone from Oracle enlighten us?
