1、連線SQLPLUS

sqlplus /nolog

2、SYSDBA登入

conn / as sysdba

3、檢視PDB

show pdbs;

4、將會話轉到具體某個DB下

alter session set container=dbname;

5、建立表空間

CREATE SMALLFILE TABLESPACE "PDSCI" DATAFILE 'D:\app\oracle\oradata\ORCL\hbres\pdsci.dbf' SIZE 100M AUTOEXTEND ON NEXT 5M MAXSIZE UNLIMITED LOGGING EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO;  

6、建立使用者

CREATE USER "PDSCI" PROFILE "DEFAULT" IDENTIFIED BY "123456" DEFAULT TABLESPACE "PDSCI" TEMPORARY TABLESPACE "TEMP" ACCOUNT UNLOCK;  

7、賦權

GRANT "CONNECT" TO "PDSCI";  

GRANT "DBA" TO "PDSCI";  

8、解決空表導不出的問題，使用者鎖定問題，密碼過期問題。

alter system set deferred_segment_creation=false;  

alter profile default limit FAILED_LOGIN_ATTEMPTS unlimited;  

ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;
