SAP* & ddic password locked in 000 client

Hi All,

Accidently SAP* and DDIC user id's have been locked in 000 client ,we need to apply some patch through 000 client and we are unable to login.

I have seen a lot of fourms to unlock these id's from database level.We are running on Oracle 10g and SAP ECC 6.0.

Please give me the exact query and other things I need to perform to unlock these users.

Regards,

Prashant
