i grant the dba role to aa, but i can only get the privilege "UNLIMITED TABLESPACE" from dba_sys_privs view,where are the privileges of the dba role?

SQL> CREATE USER aa identified by 1;
SQL> grant dba to aa;
SQL> SELECT * FROM dba_sys_privs WHERE grantee = 'AA';
GRANTEE PRIVILEGE ADMIN_OPTION
------- ------------------------ ------------
AA UNLIMITED TABLESPACE NO

They stay in the DBA role.
Change AA by DBA in your query and you will see them.

GRANTEE PRIVILEGE ADMIN_OPTION
-------- -------------------------------- ------------
SYS UPDATE ANY CUBE BUILD PROCESS NO

ADMIN_OPTION is no,but why can sys grant the privilege to other users or roles?

Oracle and/or any other technology is "rocket science" if you don't consult docs.
ADMIN_OPTION is Indicates whether the grant was with the ADMIN option (YES) or not (NO).

Just test as sys user, grant any sys privilege to user with ADMIN_OPTION and now see dba_sys_privs. It will now show you Yes.

- Never ever use SYS (or SYSDBA) but for maintenance purpose (startup, shutdown, backup, recover)
- SYS/SYSDBA is special
- SYS/SYSDBA is Oracle proprietary (try to open a SR/TAR starting with "i did that with SYS/SYSDBA" and you'll see the immediate answer)
- SYS/SYSDBA does not act like any other user
- When you use SYS/SYSDBA Oracle deactivates some code path and activates others
- Whatever you do with SYS/SYSDBA will neither validate nor invalidate the same thing with any other user.

NEVER EVER use SYS/SYSDBA for anything that can be done by another user.
Use SYS/SYSDBA ONLY for something that can't be done by someone else.

Michel
