Oracle 12c CDB PDB

先说基本用法：

先按11G之前进行

conn / as sysdba;

create user test identifed by test;

ORA-65096: 公用用户名或角色名无效.

查官方文档得知“试图创建一个通用用户，必需要用C##或者c##开头”，这时候心里会有疑问，什么是common user？不管先建成功了再说

create C##user test identifed by test;

创建成功

SQL>show con_name;

CON_NAME

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

CDB$ROOT

selectcon_id,dbid,NAME,OPEN_MODEfromv$pdbs;

CON_ID DBID NAME OPEN_MODE ---------- ---------- ------------------------------ ---------- 2 4066409480 PDB$SEED READ ONLY 3 2270995695 PDBORCL MOUNTED

SQL>alter session set container=PDBORCL;

这时再用create user test identifed by test;建立用户就可以了。

CDB和PDB是ORACLE 12C一个很亮的新特性,由于他们的引入导致传统的ORACLE数据库管理理念不少发生了改变,这里列举了部分最基本的cdb和pdb管理方式

pdb的管理可以在cdb中进行也可以在pdb中进行,如果是cdb中进行,需要PLUGGABLE关键字,如果是pdb中直接和普通数据库一样

ERROR at line 1:

ORA-65094: invalid local user or role name

创建用户默认的是container=all,在cdb中只能创建全局用户(c##开头),会在cdb和所有的pdb中创建该用户(但是pdb中的全局用户需要另外授权才能够在pdb中访问)。在pdb中只能创建的用户为本地用户

用户授权

SQL> grant connect to c##xff;

Grant succeeded.

SQL> select GRANTEE,con_id from cdb_ROLE_PRIVS where GRANTED_ROLE='CONNECT' AND GRANTEE='C##XFF';

GRANTEE CON_ID

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

C##XFF 1

SQL> grant resource to c##xff container=all;

Grant succeeded.

SQL> select GRANTEE,con_id from cdb_ROLE_PRIVS where GRANTED_ROLE='RESOURCE' AND GRANTEE='C##XFF';

GRANTEE CON_ID

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

C##XFF 1

C##XFF 3

用户授权默认情况下是只会给当前container,在cdb中也可以指定container=all,对所有open的pdb且存在该用户都进行授权

修改参数

SQL> alter system set open_cursors=500 container=all;

System altered.

SQL> conn sys/xifenfei@pdb1 as sysdba

Connected.

SQL> show parameter open_cursors;

NAME TYPE VALUE

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

open_cursors integer 500

SQL> alter system set open_cursors=100;

alter system set open_cursors=100

*

ERROR at line 1:

ORA-01219: database or pluggable database not open: queries allowed on fixed

tables or views only

SQL> alter database open;

Database altered.

SQL> alter system set open_cursors=100;

System altered.

SQL> show parameter open_cursors;

NAME TYPE VALUE

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

open_cursors integer 100

SQL> conn / as sysdba

Connected.

SQL> show parameter open_cursors;

NAME TYPE VALUE

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

open_cursors integer 500

这里可以看到在cdb中修改,pdb会继承进去;如果在pdb中修改会覆盖pdb从cdb中继承的参数含义
