Hi,

The presentation code is a proof of concept only designed to unwrap a very simple procedure whose DIANA is stored in the IDL$ tables. There is limited access to DIANA in the IDL$ tables and as stated in the paper the DIANA for packages is not stored. To unwrap packages you would need to write a complete unwrapper.

cheers

Pete

Pete,

I have a problem, when i execute EXEC SYS.DUMPDIANA.DUMP(aname => 'UL_BOOKING_REPORT') i get the following error.
ERROR at line 1:
ORA-06510: PL/SQL: unhandled user-defined exception
ORA-06512: at "SYS.DUMPDIANA", line 67
ORA-06512: at "SYS.DUMPDIANA", line 84
ORA-06512: at line 1

These also dont give proper result. They give the following

-
$$$ s_subpNotFound

EXEC SYS.PSTUB('UL_BOOKING_REPORT',NULL,:A,:B);
EXEC SYS.SUBPTXT('UL_BOOKING_REPORT',NULL,NULL,:A);

I did dump the datafile with proper no from UB2$ (Got it from running rowid.sql).

Pls help this procedure was created in oracle 8i.

Best Regards

Anenthan

is it a procedure or package or package body? - if its a package body then there is no DIANA stored.

I suspect your issue is that you are running the dumpdiana.dump not as the owner of the pl/sql yoy are trying to dump. if you are then add the usr=>'username' to the get_diana call in dump - you cannot pass this in as it defaults to usr=>user. this applies if you call the dump procedure. The other simpler approach is to call sys.dumpdian.get_diana directly and pass in the user name.

hth

Hi,

What are you trying to unwrap with this sample code? - the code is from my Blackhat presentation and is a proof of concept only to show how unwrapping works in 9i and lower. It was written to unwrap a simple procedure like http://www.petefinnigan.com/aa.sql only.

cheers

Pete

I really understand the write up and i know you delibrated much more on the process for Oracle 9i and bellow with respect to DIANA and m code. But I have an issue in house. I have a package that we wrapped in Oracle 10g. What the package does is to send notification to our numerious customers once a trasaction takes place in their account. We need to expand the scope of this package and we are stucked. The source code cannotbe trace again. Wehave the .plb only. We dont want to re invent the wheel as it took some time to get to that position . I really need your advice in this case. what can we do.
