=====
## Rest the password of 'sap*' in client 000
## Log on to oracle database using sqlplus.
sqlplus / nolog
SQL>connect /as sysdba
SQL>update .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.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.
