Oracle 12c 学习之启动关闭CDB&PDB

1、默认登陆到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、启动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

默认会有一个PDB$SEED,PDB1是通过模版创建的。

SQL> show pdbs
CON_ID CON_NAME                       OPEN MODE  RESTRICTED

---------- ------------------------------ ---------- ----------

         2 PDB$SEED                       READ ONLY  NO

         3 PDB1                           MOUNTED

    5、默认pdb未启动，手动启动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、关闭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只读打开

SQL> alter pluggable database pdb1 open read only;
Pluggable database altered.
8、切换到pdb1

SQL> alter session set container=pdb1 ;
Session altered.
SQL> show con_name
CON_NAME

------------------------------

PDB1

9、也可以这样启动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、切换到cdb,关闭cdb的同时，pdb也会跟着关闭

SQL> alter session set container=CDB$ROOT;
Session altered.

SQL> shutdown immediate; Database closed. Database dismounted. ORACLE instance shut down. SQL>
