As far as I know, row concurrency is not guaranteed with row id column.

Do you mean ORA_ROWSCN pseudo column?

Do you have a column like modify_date on your tables? Or can you obtain a row version column by concatenating two or more columns. It doesn't have to be a number column. It may also be a varchar2 or date column.

If the above suggestions don't help, we can add a new concurrency method by checking each column value in the row (In the further releases).
