oracle 12c pdb开启和关闭,及设置开机自启动

//开启数据库

sqlplus / as sysdba;                  //登录连接CDB,默认是root container;
startup;                              //open 模式,但此时的pdb模式是mounted,需要手工开启
alter session set container=testpdb1;                     //切换到某个pdb
alter pluggable database open;                            //开启选定的pdb
alter pluggable database all open;                        //开启全部pdb


//关闭数据库

alter pluggable database all close;                       //关闭所有dpb


alter session set container=testpdb1;                     //切换到某个pdb
shutdown immediate;


alter session set container = CDB$ROOT;                   //切换到cdb
shutdown immediate;

可以通过添加Trigger的形式来客制化startup时自动将PDB OPEN

使用SYS用户创建如下触发器即可:

CREATE TRIGGER open_all_pdbs
AFTER STARTUP
ON DATABASE
BEGIN
EXECUTE IMMEDIATE 'alter pluggable database all open';
END open_all_pdbs;
