SYSDBA does not have privilege to create user
I have a fresh Oracle Database 11.1.0.7.0 installation.
I am able to connect to the database using either of the following commands from Linux :
sqlplus "/ as sysdba"
sqlplus "sys/pwd as sysdba"
But after I connect, I am not able to create user. Following command gives me error:
SQL> create user adi identified by adi;
create user adi identified by adi
*
ERROR at line 1:
ORA-01031: insufficient privileges
SQL>
My assumption was that sysdba role has unlimited privileges, then why does the database throw this error.
