MYCDB Multitenant Option enabled READ WRITE 0
SQL> select con_id,name,open_mode from v$pdbs;
CON_ID NAME OPEN_MODE
2 PDB$SEED READ ONLY
- 基于PDB$SEED演示创建PDB
SQL> alter system set db_create_file_dest='/u02/oradata/';
System SET altered.
SQL> create pluggable database MYPDB1 admin user admin identified by 123456 roles=(connect) file_name_convert=('/u02/oradata/MYCDB/pdbseed','/u02/oradata/MYCDB/MYPDB1');
- 查看创建后的状态，刚刚创建的pdb status列为NEW
SQL> select pdb_id,pdb_name,status,creation_time from cdb_pdbs;
PDB_ID PDB_NAME STATUS CREATION_TIME
3 MYPDB1 NEW 02-NOV-18
2 PDB$SEED NORMAL 31-OCT-18
#如下查询，当前的数据库处于mount状态
SQL> select con_id,dbid,NAME,OPEN_MODE from v$pdbs;
CON_ID DBID NAME OPEN_MODE
2 988450796 PDB$SEED READ ONLY
3 2853971070 MYPDB1 MOUNTED
- 将pdb数据库切换到open状态
SQL> alter pluggable database MYPDB1 open;
or
SQL>alter session set container=MYPDB1 ;
SQL> startup;
SQL> select con_id,dbid,NAME,OPEN_MODE from v$pdbs;
CON_ID DBID NAME OPEN_MODE
2 988450796 PDB$SEED READ ONLY
3 2853971070 MYPDB1 READ WRITE
- 使用公共用户sys连接到刚刚创建的pdb数据库
SQL> conn sys/[email protected]:1521/MYPDB1 as sysdba;
Connected.
SQL> show user;
USER is "SYS"
SQL> show pdbs;
CON_ID CON_NAME OPEN MODE RESTRICTED

ALTER DATABASE DEFAULT TABLESPACE MYPDB1_UD;
drop tablespace USERS including contents and datafiles;
- 对用户授权
GRANT DBA to ADMIN;
grant connect,resource,unlimited tablespace to ADMIN;
grant create any directory to ADMIN;
grant drop any directory to ADMIN;
#修改密码(可选)
alter user ADMIN identified by "xag123";
#账户锁定后解锁命令(可选) sys or system
alter user ADMIN account unlock;
#设置用户密码无限次尝试登录
alter profile default limit failed_login_attempts unlimited;
#设置用户密码不过期：
alter profile default limit password_life_time unlimited;
#查看配置的参数
select profile,RESOURCE_NAME,resource_type,limit from dba_profiles where
RESOURCE_NAME in('FAILED_LOGIN_ATTEMPTS','PASSWORD_LIFE_TIME') and profile='DEFAULT';
- 使用pdb本地管理员账户连接到pdb数据库

- 创建新用户
[oracle@XAG143 ~]$ sql admin/[email protected]:1521/MYPDB1
SQL> CREATE USER OSSUSER IDENTIFIED BY "123456" DEFAULT TABLESPACE MYPDB1_UD TEMPORARY TABLESPACE TEMP_GP;
SQL> GRANT DBA to OSSUSER;
