Oracle 12c多租户常用管理命令有哪些

这篇文章给大家分享的是有关oracle 12c多租户常用管理命令有哪些的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。

--进入cdb  
sqlplus /nolog  
conn sys/sys as dba  

--查看数据库基本信息
select name,cdb from v$database;

--查看容器的相关信息
select con_id,name from v$containers;

--查看数据文件的路径
select con_id,file_name from cdb_data_files order by 1;

--显示当前连接容器信息
show con_id con_name user

--显示所有pdb
show pdbs

--start和stop根容器

--启动数据
--CDB
sqlplus / as sysdba
startup

--PDB(所有PDB)
alter pluggable database all open;
--启动pdb1库
alter pluggable database pdb1 open;

--关闭数据库
--CDB
shutdown immediate

--pdb1
alter pluggable database pdb1 close;
alter pluggable database pdb1 close immediate;
--关闭所有pdb
alter pluggable database all close immediate;

--创建公用用户(sys和system在可插拔中就是自动创建的公用用户)
sqlplus / as sysdba
create user C#dba identified by alex;


--创建公用角色
sqlplus / as sysdba
create role c##dbaprivs container=all;

grant dba to c##dbaprivs container=all;

--公用角色给公用用户
grant c##dbaprivs to c#dba container=all;

--切换容器
alter session set container=ehrpdb;
--切换回根容器
alter session set container=cdb$root;


--2创建可插拔数据库
--2.1克隆种子容器
create pluggable database cpcdb
admin user cpcadm identified by  cpcadm
file_name_convert=('/oracle/app/oracle/oradata/edw/pdbseed','/oradata/edw/cpcdb/datafile/');


--2.2直接创建数据库
CREATE PLUGGABLE DATABASE hrdb
ADMIN USER hrdba IDENTIFIED BY hrdba
STORAGE (MAXSIZE 100G MAX_SHARED_TEMP_SIZE 2G)
DEFAULT TABLESPACE hrdb DATAFILE '/oradata/EDW/hrdb/datafile/hrdb001.dbf' SIZE 512M AUTOEXTEND on next 8M maxsize 10G;

CREATE PLUGGABLE DATABASE cpcdb
ADMIN USER cpcdba IDENTIFIED BY cpcdba
STORAGE (MAXSIZE 100G MAX_SHARED_TEMP_SIZE 2G)
DEFAULT TABLESPACE tbscpc DATAFILE '/oradata/EDW/cpcdb/datafile/tbscpc001.dbf' SIZE 512M AUTOEXTEND on next 8M maxsize 10G;

--2.3创建数据案例


create pluggable database cpcdb
admin user cpcadm identified by  cpcadm
file_name_convert=('/oracle/app/oracle/oradata/edw/pdbseed','/oradata/edw/cpcdb/datafile/');

create pluggable database ncdb
admin user ncadm identified by  ncadm
file_name_convert=('/oradata/edw/pdbseed','/oradata/edw/ncdb/datafile/');


CREATE PLUGGABLE DATABASE ncdb
ADMIN USER ncdba IDENTIFIED BY ncdba
STORAGE (MAXSIZE 100G MAX_SHARED_TEMP_SIZE 2G);

--访问ncdb的插拔数据库
sqlplus sys/ncdba@oraerp:1521/ncdb as sysdba  

--关闭PDB数据库
alter pluggable database ncdb close immediate;
alter pluggable database hrdb close immediate;
alter pluggable database cpcdb close immediate;
alter pluggable database edwpdb close immediate;
--删除PDB数据库  
DROP PLUGGABLE DATABASE ncdb INCLUDING DATAFILES;  
DROP PLUGGABLE DATABASE hrdb INCLUDING DATAFILES;  
DROP PLUGGABLE DATABASE cpcdb INCLUDING DATAFILES;
DROP PLUGGABLE DATABASE edwpdb INCLUDING DATAFILES;  

--创建pdb案例
--1、cpcdb
create pluggable database cpcdb
admin user cpcadm identified by  cpcadm
file_name_convert=('/oradata/edw/pdbseed/','/oradata/edw/cpcdb/');

--2、ncdb
create pluggable database ncdb
admin user ncadm identified by  ncadm
file_name_convert=('/oradata/edw/pdbseed/','/oradata/edw/ncdb/');


--3、hrdb
create pluggable database hrdb
admin user hradm identified by hradm
file_name_convert=('/oradata/edw/pdbseed/','/oradata/edw/hrdb/');

alter pluggable database all open;

--登录cpcdb
$sqlplus sys/Oracleedw13@192.168.2.218:1531/cpcdb as sysdba

$sqlplus sys/OraEdw!23@192.168.1.105:1533/ncdb as sysdba --含有！需要单独输入密码
