Oracle 12C CDB、PDB常用管理命令
–查看PDB信息(在CDB模式下)show pdbs
--查看所有pdbselect name,open_mode from v$pdbs;
--v$pdbs为PDB信息视图
select con_id, dbid, guid, name , open_mode from v$pdbs;
--切换容器
alter session set container=orcl1
--切换到PDBorcl1容器alter session set container=CDB$ROOT
--切换到CDB容器
–查看当前属于哪个容器select sys_context('USERENV','CON_NAME') from dual;
--使用sys_context查看属于哪个容器show con_name
--用show查看当前属于哪个容器
–启动PDBalter pluggable database orcl1 open;
--开启指定PDBalter pluggable database all open;
--开启所有PDBalter session set container=orcl1;
--切换到PDB进去开启数据库
startup
–关闭PDBalter pluggable database orcl1 close;
--关闭指定的PDBalter pluggable database all close;
--关闭所有PDBalter session set container=orcl1;
--切换到PDB进去关闭数据库
shutdown immediate
–创建或克隆前要指定文件映射的位置(需要CBD下sysdba权限)
alter system set db_create_file_dest='/u01/app/oracle/oradata/orcl/orcl2';
–创建一个新的PDB:(需要CBD下sysdba权限)
create pluggable database test admin user admin identified by admin;
alter pluggable database test_pdb open;
--将test_pdb 打开
–克隆PDB(需要CBD下sysdba权限)create pluggable database orcl2 from orcl1;
--test_pdb必须是打开的,才可以被打开alter pluggable database orcl2 open;
--然后打开这个pdb
–删除PDB(需要CBD下sysdba权限)alter pluggable database orcl2 close;
--关闭之后才能删除drop pluggable database orcl2 including datafiles;
--删除PDB orcl2
–设置CDB启动PDB自动启动(在这里使用的是触发器)
CREATE OR REPLACE TRIGGER open_pdbs
AFTER STARTUP ON DATABASE
BEGIN
EXECUTE IMMEDIATE 'ALTER PLUGGABLE DATABASE ALL OPEN';
END open_pdbs;
