1、连接SQLPLUS

sqlplus /nolog

2、SYSDBA登录

conn / as sysdba

3、查看PDB

show pdbs;

4、将会话转到具体某个DB下

alter session set container=dbname;

5、创建表空间

CREATE SMALLFILE TABLESPACE “tablespacename” DATAFILE ‘D:apporacleoradataORCLhbrests.dbf’ SIZE 100M AUTOEXTEND ON NEXT 5M MAXSIZE UNLIMITED LOGGING EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO;  

6、创建用户

CREATE USER “username” PROFILE “DEFAULT” IDENTIFIED BY “123456” DEFAULT TABLESPACE “tablespacename” TEMPORARY TABLESPACE “TEMP” ACCOUNT UNLOCK;  

7、赋权

GRANT “CONNECT” TO “username”;  

GRANT “DBA” TO “username”;  

8、解决空表导不出的问题，用户锁定问题，密码过期问题。

alter system set deferred_segment_creation=false;  

alter profile default limit FAILED_LOGIN_ATTEMPTS unlimited;  

ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;
