Solução
It is really easy to log in as another user, just use the proxy user feature that is available since 8i. Unfortunately it does not work with SYS, but works with any other user. Basically you can grant the privilege to users to connect as another user.
SQL> alter user system identified by Oracle123;
User altered.
SQL> alter user hr identified by password account unlock;
User altered.
So the password of SYSTEM
is Oracle123
, and the password of HR
is password
. Now allow SYSTEM
to connect as HR
:
SQL> alter user hr grant connect through system;
User altered.
Finally, connect with SYSTEM
and its password, providing HR
in the brackets:
SQL> connect system[hr]/Oracle123
Connected.
SQL> show user
USER is "HR"
You can use any user for this, except SYS
:
SQL> alter user hr grant connect through sys;
alter user hr grant connect through sys
*
ERROR at line 1:
ORA-28154: Proxy user may not act as client 'SYS'
Outras dicas
you can use below command to change the password
alter user username identified by newpassword;
