Issue while creating common user in 12cR1

Hi All,

I was trying to create a common user for Golden gate bidirectional setup. However getting the below error while trying to do so:

SQL> SQL> create user c##sandeep identified by password;

create user c##sandeep identified by password

                                     *

ERROR at line 1:

ORA-01031: insufficient privileges

SQL> create user c##sandeep identified by password container=all;

create user c##sandeep identified by password container=all

                                     *

ERROR at line 1:

ORA-01031: insufficient privileges

SQL> sho user

USER is "SYS"

Even from SYS user I'm getting this error.

Can anyone please help me with this.

Thanks,

Sandeep
