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。丸趣 TV 小编觉得挺实用的，因此分享给大家做个参考，一起跟随丸趣 TV 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/[email protected]:1531/cpcdb as sysdba

$sqlplus sys/[email protected]:1533/ncdb as sysdba – 含有！需要单独输入密码
