Oracle 12c 多租户在 CDB 中 Plug A PDB,Unplugging A PDB

Oracle 数据库 12 c 中介绍了多租户选项允许单个容器数据库（CDB）来承载多个单独的可插拔数据库 (PDB)。
本文简单的演示了如何在 CDB 中 Plug A PDB,Unplugging A PDB 操作。

一、 plugged PDB into Unplugged PDB
SQL> show pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 PDB01 READ WRITE NO
SQL>alter pluggable database pdb01 close immediate;
SQL>alter pluggable database pdb01 unplug into '/home/oracle/pdb01.xml';
[oracle@12c01 ~]$ pwd
/home/oracle
[oracle@12c01 ~]$ ll pdb01.xml
-rw-r--r--. 1 oracle oinstall 7758 May 7 05:09 pdb01.xml
[oracle@12c01 ~]$ cat pdb01.xml
<?xml version="1.0" encoding="UTF-8"?>
<PDB>
<xmlversion>1</xmlversion>
<pdbname>PDB01</pdbname>
<cid>3</cid>
<byteorder>1</byteorder>
<vsn>203424000</vsn>
<vsns>
<vsnnum>12.2.0.1.0</vsnnum>
<cdbcompt>12.2.0.0.0</cdbcompt>
<pdbcompt>12.2.0.0.0</pdbcompt>
<vsnlibnum>0.0.0.0.24</vsnlibnum>
<vsnsql>24</vsnsql>
<vsnbsv>8.0.0.0.0</vsnbsv>
</vsns>
<dbid>2550500229</dbid>
...省略
SQL> show pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 PDB01 MOUNTED
SQL> drop pluggable database pdb01 keep datafiles;
Pluggable database dropped.
SQL> show pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO

二、 Plug Unplugged PDB into CDB

SQL> SELECT NAME,CDB FROM V$DATABASE;
NAME CDB
--------- ---
ANDYCDB YES
SQL> create pluggable database pdb01 using '/home/oracle/pdb01.xml';
Pluggable database created.
SQL> show pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 PDB01 MOUNTED
SQL> alter pluggable database pdb01 open;
Pluggable database altered.
SQL> show pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 PDB01 READ WRITE NO
