  • 1. Pluggable Database tutorial Part 2 Osama Mustafa Page 1 In my Part 1 Tutorial for how to deal with Pluggable database 12c I mentioned how to use pluggable database, How to create pluggable database, how to create table space, and how to open/close pluggable database. Please checks the Part (1) before continue reading this article here. Welcome to Pluggable database Part 2  Rename Pluggable Database  Manage Pluggable database  Drop Pluggable database  Security In Pluggable database SQL> select name, con_id from v$active_services order by 1; NAME CON_ID ----------------------------- ---------- TEST 3 As you see in the above query, I already created pluggable database called test. and it's in Read write Mode. Rename Pluggable database SQL> alter pluggable database TEST close immediate ; Pluggable database altered. SQL> alter pluggable database TEST open restricted ; Pluggable database altered. SQL> select name, open_mode from v$pdbs; NAME OPEN_MODE ------------------------------ ---------- TEST READ WRITE SQL> alter pluggable database TEST rename global_name to new ; Pluggable database altered.
  • 2. Pluggable Database tutorial Part 2 Osama Mustafa Page 2 SQL> select name, con_id from v$active_services order by 1; NAME CON_ID --------------------------------------- ---------- new 3 if you are not connected to pluggable database or set session container then you will receive error message ORA-65046: operation not allowed from outside a pluggable SQL> alter pluggable database new close immediate; Pluggable database altered. SQL> alter pluggable database new open ; Pluggable database altered. Manage Pluggable Database Back to root container using / as sysdba like below: SQL> conn / as sysdba Connected. SQL> select name, con_id from v$active_services order by 1; NAME CON_ID --------------------------------------------------- ---------- SYS$BACKGROUND 1 SYS$USERS 1 db12c 1 db12cXDB 1 new 3 We Control which list for for tablespace & datafiles by using con_id.  List tablespace in root container
  • 3. Pluggable Database tutorial Part 2 Osama Mustafa Page 3 SQL> select tablespace_name, con_id from cdb_tablespaces where con_id=1; TABLESPACE_NAME CON_ID ------------------------------ ---------- SYSTEM 1 SYSAUX 1 UNDOTBS1 1 TEMP 1 USERS 1 CDATA 1  List Database In root Container SQL> select file_name, con_id from cdb_data_files where con_id=1; FILE_NAME CON_ID --------------------------------------------------------------------- ---------- /u01/app/oracle/oradata/db12c/users01.dbf 1 /u01/app/oracle/oradata/db12c/undotbs01.dbf 1 /u01/app/oracle/oradata/db12c/sysaux01.dbf 1 /u01/app/oracle/oradata/db12c/system01.dbf 1 /u01/app/oracle/oradata/db12c/gls/test.dbf 1  Temp Tablespace in root container SQL> select file_name, con_id from cdb_temp_files where con_id=1; FILE_NAME CON_ID ----------------------------------------------------------------------------- ---------- /u01/app/oracle/oradata/db12c/temp01.dbf 1  Create Tablespace ( already mentioned in Part (1)) SQL> create tablespace test datafile '/u01/app/oracle/oradata/db12c/gls/test03.dbf' size 20M; Tablespace created.
  • 4. Pluggable Database tutorial Part 2 Osama Mustafa Page 4 SQL> select tablespace_name, con_id from cdb_tablespaces order by con_id; TABLESPACE_NAME CON_ID ------------------------------ ---------- SYSTEM 1 TEST 1 CDATA 1 SYSAUX 1 TEMP 1 UNDOTBS1 1 USERS 1 SYSAUX 2 TEMP 2 SYSTEM 2 TEMP 3 SYSAUX 3 PDB_TEST 3 SYSTEM 3 14 rows selected.  Create temp tablespace SQL> create temporary tablespace temp_test tempfile '/u01/app/oracle/oradata/db12c/gls/temp_test.dbf' size 20M ; Tablespace created. SQL> select file_name, con_id from cdb_temp_files where con_id=1; FILE_NAME CON_ID --------------------------------------------------------------------------- ---------- /u01/app/oracle/oradata/db12c/temp01.dbf 1 /u01/app/oracle/oradata/db12c/gls/temp_test.dbf 1 The Same Steps in root container for create tablespace and temp tablespace for pluggable database.
  • 5. Pluggable Database tutorial Part 2 Osama Mustafa Page 5 Security In Pluggable Database In This Section we will discuss how to manage Users, roles and privileges. before Demonstration you need to know what is the difference between two users type :  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. To Create Common Users you need to be connected to root container. 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##OSAMA 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.
  • 6. Pluggable Database tutorial Part 2 Osama Mustafa Page 6 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.
  • 7. Pluggable Database tutorial Part 2 Osama Mustafa Page 7 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 ; create role hr container=all * ERROR at line 1: ORA-65050: Common DDLs only allowed in CDB$ROOT SQL> create user hr identified by hr container=all ; create user hr identified by hr container=all * ERROR at line 1: ORA-65050: Common DDLs only allowed in CDB$ROOT ---> you cannot create a common role inside a PDB.
  • 8. Pluggable Database tutorial Part 2 Osama Mustafa Page 8 Check user privileges: SQL> select grantee, privilege, common, con_id from cdb_sys_privs where privilege='CREATE SESSION' and grantee='TEST'; GRANTEE PRIVILEGE COM CON_ID -------------- --------------------------------------- TEST CREATE SESSION NO 3 Drop Pluggable Database SQL > drop pluggable database new including datafiles; Pluugable database dropped.
