3.通过现有的PDB创建一个新的PDB

發布時間：2024/10/12 编程问答 34 豆豆

生活随笔收集整理的這篇文章主要介紹了 3.通过现有的PDB创建一个新的PDB 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

實驗說明：創建PDB除了可以通過種子PDB創建外，現在測試通過一個現有的用戶PDB克隆創建新的PDB數據庫實驗步驟： 1.創建測試數據 SQL> alter session set container=emp;
Session altered.

SQL> conn dsg/dsg@emp
Connected.
SQL> create table test (id number(8));
Table created.

SQL> begin
? 2? for i in 1..100 loop
? 3? insert into test values(i);
? 4? end loop;
? 5? commit;
? 6? end;
? 7? /
PL/SQL procedure successfully completed.

SQL> select count(*) from test;
? COUNT(*)
----------
?????? 100 2.通過現有PDB創建新的PDB ?EMPTEST SQL> conn / as sysdba
Connected.
SQL> create pluggable database emptest from emp;
create pluggable database emptest from emp
*
ERROR at line 1:
ORA-65081: database or pluggable database is not open in read only mode
----源數據庫必須在read only狀態

SQL> alter pluggable database emp close;

Pluggable database altered.

SQL> alter pluggable database emp open read only;
Pluggable database altered.

SQL> create pluggable database emptest from emp;
Pluggable database created. 3.在tnsnames.ora中添加下面的信息，這樣就可以通過服務名連接數據庫了

EMPTEST =
? (DESCRIPTION =
??? (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
??? (CONNECT_DATA =
????? (SERVER = DEDICATED)
????? (SERVICE_NAME = EMPTEST)
??? )
? )

新的PDB創建成功，查看alert日志：

create pluggable database emptest from emp
Sun Jan 19 22:26:48 2014
****************************************************************
Pluggable Database EMPTEST with pdb id - 4 is created as UNUSABLE.
If any errors are encountered before the pdb is marked as NEW,
then the pdb must be dropped
****************************************************************

****************************************************************
Post plug operations are now complete.
Pluggable database EMPTEST with pdb id - 4 is now marked as NEW.
****************************************************************
Completed: create pluggable database emptest from emp

新的PDB創建后數據庫會自動監聽

[oracle@localhost datafile]$ lsnrctl status

說明： PDB的一些更改操作不能在CDB級別更改，必須切換到PDB下，下面以修改GLOBAL_NAME為例： SQL> select service_id,name,pdb from v$services;

SERVICE_ID NAME???????????????????????????????????????????????????????????? PDB ---------- ---------------------------------------------------------------- ------------------------------ 0 emptest??????????????????????????????????????????????????????????EMPTEST 6 emp ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?

alter pluggable database emptest rename global_name to emp_test
?????????????????????????????????????????????????????? *
ERROR at line 1:

SQL> alter pluggable database emptest close;
alter pluggable database emptest close
*
ERROR at line 1:

下面以RESTRICTED 模式打開數據庫
SQL> alter pluggable database emptest open restricted;
Pluggable database altered.

SQL> conn sys/oracle@emptest as sysdba
Connected.
SQL> alter pluggable database emptest rename global_name to emp_test;
Pluggable database altered.

SQL> select service_id,name,pdb from v$services;
