本文主要介紹oracle數據庫創建後進行的數據庫升級(10.2.0.1-10.2.0.4)，代碼如下：
[sql] view plaincopy
SQL> --查看當前數據庫版本
SQL> select * from v$version;
SQL> --給用戶scott解鎖
SQL> alter user scott account unlock;
SQL> --查看表空間
SQL> select * from dba_tablespaces;
SQL> --查看數據文件存放位置
SQL> select * from dba_data_files;
SQL> --創建測試表空間
SQL> create tablespace ts_upgrade datafile '/u02/oradata/data/orcl/ts_upgrade01.dbf' size 5m autoextend on maxsize 30g;
SQL> --創建用戶
SQL> create user u_upgrade identified by "123456" default tablespace ts_upgrade temporary tablespace temp;
SQL> --為用戶賦權
SQL> grant connect,resource to u_upgrade;
SQL> --創建測試表
SQL> create table u_upgrade.dept as select * from scott.dept;
SQL> select * from u_upgrade.dept;
