Release 10.1A: OpenEdge Data Management:
DataServer for ORACLE

Transactions

The ORACLE RDBMS handles transaction roll back and recovery, but the Progress 4GL transaction scoping rules apply.

In the Progress 4GL, transactions end at the end of the outermost block where an update takes place. When a transaction that updates an ORACLE database ends successfully, the Progress 4GL sends a COMMIT to the ORACLE instance. If you interrupt the transaction, the Progress 4GL sends a ROLLBACK to the ORACLE instance.

See OpenEdge Development: Progress 4GL Handbook for more information on how the Progress 4GL handles transactions and error conditions.
