- Common : when you create this kind of users in root it’s automatically replicated in all Pluggable database.
- Local : this kind of users only created on pluggable database that you are connected to it now. and dose not effect on others pluggable database.
SQL> conn / as sysdba
Connected.
SQL> create user c##osama identified by osama ;User created.
SQL> select username, common, con_id from cdb_users where username like ‘C##%’;
USERNAME COM CON_ID

C##TEST YES 1

C##TEST YES 3
C##OSAMA YES 3
SQL> grant create session to c##osama ;Grant succeeded.
SQL> conn c##osama/osama@test12c:1521/db12c ;
Connected.
Let’s connect to pluggable database :
The user i will created it here will not appear in root container.
SQL> conn sys/sys@test12c:1521/new as sysdba
Connected.
SQL> create user test identified by test ;User created.
SQL> grant create session to test ;Grant succeeded.
SQL> select username, common, con_id from cdb_users where username =’TEST’;
USERNAME COM CON_ID
—————— ———-
TEST NO 3
SQL> conn test/test@test12c:1521/new ;
Connected.
Same rules and conditions applied on Roles if you created in Root Container it will be replicated to pluggable database, on other hand if you created in Pluggable database it will be local without effecting Container.
Let’s connect to Root Container
SQL> conn / as sysdba
Connected.
SQL> create role c##root_role ;Role created.
SQL> select role, common, con_id from cdb_roles where role=’C##ROOT_ROLE’;
ROLE COM CON_ID

C##ROOT_ROLE YES 1
C##ROOT_ROLE YES 3
SQL> conn sys/sys@test12c:1521/new as sysdba
Connected.
SQL> create role test2;Role created.
SQL> select role, common, con_id from cdb_roles where role=’TEST2′;
ROLE COM CON_ID
—————- — ———-
TEST2 NO 3
SQL> create role hr container=all ;

SQL > drop pluggable database new including datafiles;
Pluugable database dropped.

Thank you

Nice, I would like to add below for Pluggable database and common users for the readers:1. trigger to automatically opens all PDBs after startup root container database—————————————create or replace trigger Sys.After_Startup after startup on database begin execute immediate 'alter pluggable database all open'; end After_Startup;/2. Common user name format restriction—————————————Common user must start with c## and automatically replicated in each PDB except the seed PDB. Common users can connect to any PDB. ThanksMonowar
