Archived redo log not to recoed DML statements, only to record DDL statements. Why?
Please help me!

Answer 1

Archived redo log not to recoed DML statements, only to record DDL statements. Why?This simply isn't true. This may be a bug in your unsupported 10.2.0.3, which needs to be upgraded anyway, but it has always worked.
Also one usually doesn't mine the current open online redologs.
