Logminer Question

We're trying to figure out exactly what an application has done in the db. I restored an archive log from tape and mined it.

When querying the logminer view I'm seeing two rows for a transaction in V$LOGMNR_CONTENTS The first row has sql entries in SQL_REDO and SQL_UNDO, and the ROLLBACK field is 0

The second row has sql only in SQL_REDO and the ROLLBACK field is 1

Both rows have the same SCN and TIMESTAMP, does this mean that the first row was applied and the second was indeed a rollback entry?

What's especially puzzling is we are not seeing any lost connections or abnormal program terminations, so what's causing this rollback entry?

all ideas and comments welcome.

thanks
