Does an ORMIT™-OpenJava Oracle Forms migration keep transactions? Commits and rollbacks as in Oracle Forms, with all blocks in one transaction?

Yes. The compatibility service reproduces the whole Oracle Forms save sequence, from validation through POST to COMMIT_FORM. That includes several blocks and their triggers taking part in the same transaction. Commits and rollbacks are managed by the back end and the Oracle database.
