Logminer Unsupported error

Question

Hi
i am working in oracle10g Database..
my problem is ,i find out logfile transaction..why means? some time archivelog created more file within one minute..
so,i used Logminer ...
Logminer done correctly.but i can't get the correct username,operation
sql>select * from V$LOGMNR_CONTENTS;
it will come like operation=Unsupported, user name=unknown
how to find the username and operation ??
in oracle document i found out this
UNSUPPORTED = change was caused by operations not currently supported by LogMiner (for example, changes made to tables with ADT columns)
note: The database imported from oracle8 to oracle10g
please help...

But we are not use LOB and I don’t think we have that
much of ADT and encrypted values in our database
I get 23996 unsupported values from 65536 number
of row in log table
I think my database is generating unnecessary archive
logs number of archive log generation is very high
that’s why i want to know which operation is going on
the database
So please help me soonIf you have Enterprise Manager running, then you cannot easily confirm what you have in tables and what you do not have unless you know all the object structures in SYSMAN schema.
You may also have problems easily knowing what datatypes and attributes SYS and Background processes are using in the database at a particular time.
There is more unsupported datatype and attrubute types: bfile, nested tables and varrays , xmltype, table compression, object refs etc.
Instead of selecting *, you can try using elimination process at least to help you identify the owner/user of the objects.
