Error: ORA-65096: invalid common user or role name in oracle 19c database

Dear DBA-Mates, Happy New Year to you all!!!

Hope you all doing good.

Here, we would like to share user creation error ORA-65096: invalid common user or role name in 19c database.

How to create database user in 19c oracle database because when you create database user in oracle 19c database you may get an ORA error like ORA-65096 as shown below in details.

So, to avoid that user creation error either we can set one hidden parameter to true or else put pre-fix word as c##.

For kind information without alter of the hidden parameter or pre-fix word c## you can’t create the user in oracle 19c database like previous version of the oracle database.

Please find the below details:

Error:

SQL> show user

USER is "SYS"

SQL> create user ogg identified by ogg account unlock;

create user ogg identified by ogg account unlock

            *

ERROR at line 1:

ORA-65096: invalid common user or role name

SQL>

 

Solutions:

1.   Here, we have one hidden parameter which needs to be set as True as shown in below command:

SQL> alter session set "_ORACLE_SCRIPT"=true;

 Session altered.

 SQL> show user

USER is "SYS"

SQL>

 SQL> create user ogg identified by ogg account unlock;

 User created.

 SQL>

 

SQL> GRANT CONNECT, RESOURCE, DBA TO ogg;

 Grant succeeded.

 SQL>

SQL> conn ogg/ogg

Connected.

SQL> show user

USER is "OGG"

SQL>

2.   As discussed, there is another method also which can be used here but it will be different like pre-fix word as shown below:

 

SQL> create user C##OGGS identified by oggs;

 User created.

 SQL> create user c##OGGS identified by oggs container=all;

 User created.

SQL>
