LogMiner and "UNKNOWN"."OBJ# and HEXTORAW

 Hi All,

Oracle 10g R2 Standard 

I had to dig into archived logs from last week for about 2 hour window on our production database.  Also we don't have additional supplemental logging on.

I'm mining on the same database.

But when I mine the logs, I got  -

update "UNKNOWN"."OBJ# 472665" set "COL 7" = HEXTORAW('c10d')

same thing for INSERTs.

I tried all 3 methods of using dictionary and still no luck. 

I know there is no DDL occured on the tables of interest, so why am I not getting actual object names and data values?

Is there anyway to get meaningful SQL REDO for this?
