In this post I will be showing you how to create an user in the CDB, what are called “Common Users” (users using the COMMON_USER_PREFIX parameter to set the user prefix at creation time) and then afterwards an user in a PDB called TECHDATABASKET , which are the “Local Users”.
1- Creating Common User in a CDB:
SQL> select instance_name, status from v$instance; INSTANCE_NAME STATUS ---------------- ------------ cdb4 OPEN SQL> show parameters COMMON_USER_PREFIX NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ common_user_prefix string C## SQL> show con_name CON_NAME ------------------------------ CDB$ROOT SQL> CREATE USER c##techdatabasket IDENTIFIED BY my_password DEFAULT TABLESPACE USERS QUOTA UNLIMITED ON USERS CONTAINER = ALL; 2 3 4 User created.
2- Creating Local User in a PD
SQL> select name from v$pdbs; NAME ------------------------------ PDB$SEED PDBCDB4 CDBSEED CDBSEED2 MIG NONCDB TECHDATABASKET TECHDATABASKET2 8 rows selected. SQL> alter session set container=TECHDATABASKET; Session altered. SQL> CREATE USER techpdb IDENTIFIED BY my_password DEFAULT TABLESPACE USERS QUOTA UNLIMITED ON USERS CONTAINER = CURRENT; 2 3 4 User created.
Neste post estarei mostrando simplificamente como criar um usuário no CBD, o que chamados de “Common Users” (usuários que utilizam o parâmetro COMMON_USER_PREFIX para definir o prefixo do usuário no momento da criação) e posteriormente a criação de um usuário em um PDB chamado TECHDATABASKET, o que chamamos de “Local Users”.
1- Criando o usuário no CDB:
SQL> select instance_name, status from v$instance; INSTANCE_NAME STATUS ---------------- ------------ cdb4 OPEN SQL> show parameters COMMON_USER_PREFIX NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ common_user_prefix string C## SQL> show con_name CON_NAME ------------------------------ CDB$ROOT SQL> CREATE USER c##techdatabasket IDENTIFIED BY my_password DEFAULT TABLESPACE USERS QUOTA UNLIMITED ON USERS CONTAINER = ALL; 2 3 4 User created.
2- Criando um usuário local no PDB:
SQL> select name from v$pdbs; NAME ------------------------------ PDB$SEED PDBCDB4 CDBSEED CDBSEED2 MIG NONCDB TECHDATABASKET TECHDATABASKET2 8 rows selected. SQL> alter session set container=TECHDATABASKET; Session altered. SQL> CREATE USER techpdb IDENTIFIED BY my_password DEFAULT TABLESPACE USERS QUOTA UNLIMITED ON USERS CONTAINER = CURRENT; 2 3 4 User created.
