===== 
## Rest the password of 'sap*' in client 000 
## Log on to oracle database using sqlplus. 
sqlplus / nolog 
SQL>connect /as  sysdba 
SQL>update <SchemaOwner>.USR01 set bname='SAP*1' where bname='SAP*'  and MANDT=000;
## [ e.g.: update SAPR3.USR01 set bname='SAP*1' where bname='SAP*'  and MANDT=000; ] 
## [e.g. : update SAP<SID>.USR01 set bname='SAP*1' where bname='SAP*'  and MANDT=000;]
SQL>commit; 
SQL>exit
## This will reset the user SAP* in client 000 . After loggin in client with user SAP* change the passwords for other users.
## You can user client number of your respective client.
## Please note do not reset any other user than SAP* with this method.
