Oracle数据库关闭
show pdbs;
alter pluggable database all close;
shutdown immediate;
exit;
Isnrctl stop

Oracle数据库启动
startup;
show pdbs;
alter pluggable database all open;
exit;
Isnrctl start

日志路径
select * from v$diag info;

Oracle PDB数据库登录
show pdbs;
show con_name;
切换到PDB
alter session set container=ITPUXPDB;

Oracle PDB表空间创建
create tablespace fgedu datafile '/oracle/app/oracle/oradata/itpuxdb/itpuxpdb/fgedu01.dbf' size 10m;

Oracle PDB用户创建
create user fgedu identified by fgedu123 default tablespace fgedu；
grant dba to fgedu；

Oracle PDB用户登录

create table itpuxt1(id number(12)primary key,name varchar(20));

Oracle PDB数据插入
insert into itpuxt1 values(1,'fgedu01');
insert into itpuxt1 values(2,'fgeduo2'');
