Oracle 12c 學習之啟動關閉CDB&PDB

pro sysdba pdb lob ins connect nec plus start
1、默認登陸到CDB
<roidb01:cdb:/home/oracle>$sqlplus / as sysdba
SQL*Plus: Release 12.1.0.2.0 Production on Sat Jan 20 11:01:46 2018
Copyright (c) 1982, 2014, Oracle. All rights reserved.
Connected to an idle instance.
2、啟動CDB
SQL> startup
ORACLE instance started.
Total System Global Area 1560281088 bytes
Fixed Size 2924784 bytes
Variable Size 956305168 bytes
Database Buffers 587202560 bytes
Redo Buffers 13848576 bytes
Database mounted.
Database opened.
3、查看容器名
SQL> show con_name
CON_NAME
------------------------------
CDB$ROOT
4、查看pdb
默認會有一個PDB$SEED,PDB1是通過模版創建的。
SQL> show pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 PDB1 MOUNTED
5、默認pdb未啟動，手動啟動pdb
SQL> alter pluggable database all open;
Pluggable database altered.
SQL> show pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 PDB1 READ WRITE NO
6、關閉pdb
SQL> alter pluggable database pdb1 close;
Pluggable database altered.
SQL> show pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 PDB1 MOUNTED
7、pdb只讀打開
SQL> alter pluggable database pdb1 open read only;
Pluggable database altered.
8、切換到pdb1
SQL> alter session set container=pdb1 ;
Session altered.
SQL> show con_name
CON_NAME
------------------------------
PDB1
9、也可以這樣啟動pdb
SQL> shutdown immediate;
Pluggable Database closed.
SQL> startup
Pluggable Database opened.
SQL> show pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
3 PDB1 READ WRITE NO
10、切換到cdb,關閉cdb的同時，pdb也會跟著關閉
SQL> alter session set container=CDB$ROOT;
Session altered.
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
