  • Pluggable Database Tutorial Part 1 Osama Mustafa Page 1 [oracle@test12c Desktop]$ sqlplus / as sysdba SQL*Plus: Release 12.1.0.1.0 Production on Wed Jul 3 19:05:10 2013 Copyright (c) 1982, 2013, Oracle. All rights reserved. Connected to: Oracle Database 12c Enterprise Edition Release 12.1.0.1.0 - 64bit Production With the Partitioning, OLAP, Advanced Analytics, Real Application Testing and Unified Auditing options SQL>show con_name CON_NAME ------------------- CDB$ROOT Where CON_NAME: Displays the name of the Container to which you are connected when connected to a Consolidated Database. For non-consolidated database, it will return "Non Consolidated". SQL>show con_id CON_ID ------------ 1 Where CON_ID: Displays the id of the Container to which you are connected when connected to a Consolidated Database. If issued when connected to a non-Consolidated Database, this command returns 0.
  • Pluggable Database Tutorial Part 1 Osama Mustafa Page 2 Now I want to check how Name for my my pluggable database , while installation i chosen five container with prefix db_ SQL>select name, con_id from v$active_services order by 1; NAME CON_ID SYS$BACKGROUND 1 SYS$USERS 1 db12c 1 db12cXDB 1 Db_1 2 Db_2 3 Listener will look like the below: Example how to connect Container, In my case i didn't create service in tnsnames.ora i am using easy connect: SQL>conn sys/sys@localhost:1521/db_1 as sysdba Connected. SQL>show con_name CON_NAME ---------------- DB_1 SQL>show con_id
  • Pluggable Database Tutorial Part 1 Osama Mustafa Page 3 CON_ID ------------ 3 Work On Pluggable Database: After create Container and enable pluggable database, we need to add new one since container empty. Under /u01/app/oracle/oradata ,create new folder [oracle@test12c db12c]$ mkdir test [oracle@test12c db12c]$ chmod -R 775 test Sqlplus / as sysdba SQL >create pluggable database TEST admin user admin identified by admin file_name_convert= ('/u01/app/oracle/oradata/db12c/pdbseed/','/u01/app/oracle/oradata/db12c/test/'); Pluggable database created. SQL>select pdb_name, status from cdb_pdbs; PDB_NAME Status ----------------------- ------------ PDB$SEED NORMAL TEST NEW SQL>select name, open_mode from v$pdbs; NAME OPEN_MODE ------------------------------ ---------- PDB$SEED READ ONLY TEST MOUNTED SQL>select name, con_id from v$active_services order by 1; NAME CON_ID ---------------------------------------------- SYS$BACKGROUND 1 SYS$USERS 1 db12c 1 db12cXDB 1 TEST 3
  • Pluggable Database Tutorial Part 1 Osama Mustafa Page 4 Now Con_id=3 , Most of Oracle Data Dictionary contains new_column called con_id , to check datafile related to new pluaggable database : SQL>select name from v$datafile where con_id=3 ; NAME -------------------------------------------------------------------------------- /u01/app/oracle/oradata/db12c/gls/system01.dbf /u01/app/oracle/oradata/db12c/gls/sysaux01.dbf Manage Oracle Container and Pluggable Database : If you need to shutdown container, it will not be different as before: SQL>show con_name CON_NAME ------------------------------ CDB$ROOT SQL>shutdown ; Database closed. Database dismounted. ORACLE instance shut down. SQL>startup ; ORACLE instance started. Total System Global Area 1252663296 bytes Fixed Size 2287864 bytes Variable Size 788530952 bytes Database Buffers 452984832 bytes Redo Buffers 8859648 bytes Database mounted. Database opened. Check status for PDB : SQL>select name, open_mode from v$pdbs; NAME OPEN_MODE ------------------------------ ---------- PDB$SEED READ ONLY TEST MOUNTED
  • Pluggable Database Tutorial Part 1 Osama Mustafa Page 5 If you the above Status for Test Database you will see it as mounted state which mean we cannot create anything yet on database, Let's Open it SQL>alter pluggable database TEST open; Pluggable database altered. SQL>select name,open_mode from v$pdbs ; NAME OPEN_MODE ------------------------------ ---------- PDB$SEED READ ONLY TEST READ WRITE The same for close Option SQL>alter pluggable database TEST close immediate; Pluggable database altered. SQL>select name,open_mode from v$pdbs ; NAME OPEN_MODE ------------------------------ ---------- PDB$SEED READ ONLY TEST MOUNTED Now you can open/close all pluggable database : SQL >Alter pluggable database all Open; SQL >Alter pluggable database all close ; SQL>select tablespace_name, con_id from cdb_tablespaces where con_id=3 ; TABLESPACE_NAME CON_ID ------------------------------ ---------- SYSTEM 3 SYSAUX 3 TEMP 3 to get data file SQL>select file_name, con_id from cdb_data_files where con_id=3 ; NAME -------------------------------------------------------------------------------- /u01/app/oracle/oradata/db12c/gls/system01.dbf /u01/app/oracle/oradata/db12c/gls/sysaux01.dbf
  • Pluggable Database Tutorial Part 1 Osama Mustafa Page 6 SQL>select file_name, con_id from cdb_temp_files where con_id=3; FILE_NAME CON_ID ------------------------------------------ /u01/app/oracle/oradata/db12c/gls/pdbseed_temp01.dbf 3 If you do the below query to create table space, it will not be created under TEST database, therefore it will be created on root : SQL >create tablespace cdata datafile '/u01/app/oracle/oradata/db12c/gls/test.dbf' SIZE 30M; SQL>select tablespace_name, con_id from cdb_tablespaces order by con_id; TABLESPACE_NAME CON_ID ------------------------------ ---------- SYSTEM 1 CDATA 1 SYSAUX 1 TEMP 1 UNDOTBS1 1 USERS 1 SYSTEM 2 TEMP 2 SYSAUX 2 SYSTEM 3 SYSAUX 3 TEMP 3 12 rows selected. Same for temp tablespace : SQL>create temporary tablespace root_temp tempfile '/u01/app/oracle/oradata/db12c/temp_01.dbf' SIZE 30M; If you need to create Tablespace in pluggable database follow the below, you have to options  connect to pluggable database in our case test using tnsnames.ora or easy connect o connect sys/sys@localhost:1521/test  alter session command line o alter session set container= <Name>
  • Pluggable Database Tutorial Part 1 Osama Mustafa Page 7 SQL>alter session set container=TEST; Session altered. SQL>create tablespace pdb_test datafile '/u01/app/oracle/oradata/db12c/TEST/test_pdb.dbf' SIZE 20M; Tablespace created. SQL>select tablespace_name, con_id from cdb_tablespaces order by con_id; TABLESPACE_NAME CON_ID ------------------------------ ---------- SYSTEM 3 SYSAUX 3 TEMP 3 PDB_TEST 3 Same for temporary table space, next post i will provide another manage for pluggable database.
