Please read the first email carefully and if you know the reason, I would be glad to have your Idea.

The question is clear, I am using Oracle 9i. I logined as SYSdBA
and ran the DBMS_Stat for my shcema I got the error message.
After verifing I found that it is working form some shcema but for
the one that I mentioned.

I exported the schema, removed the tablespace and created again,
impoted the schema, but still DBMS_Stat gives me error message.

that's it.
