1.安裝Oracle 10g r2的軟件
2.打Oracle 10g最新的補丁，我打的是升級到10.2.0.2的補丁
3.運行Pre-Upgrade Information Tool.它用來分析升級到10g前你要做的一些操作，比如需要增加或減少的參數等.
啟動要升級的DB，用SYSDBA運行10g的Oracle_HOME/rdbms/admin下的utlu102i.sql，查看產生的日志.
SQL> SPOOL info.log
SQL> @utlu102i.sql
SQL> SPOOL OFF
下面是我的info.log.
SQL> @d:\utlu102i.sql;

copy oracle 9i的pfile(D:\oracle\ora92\database\INITzhangye.ORA)到oracle 10g的pfile(D:\Oracle10g\database\INITzhangye.ORA).
檢查info.log，對Oracle 10g的pfile修改.

4.運行Oracle Net Configuration Assistant，生成10g的listener.ora
5.rman備份DB.
6.stop所有Oracle 9i的服務.
刪除Oracle 9i的服務.
C:\> ORADIM -DELETE -SID ZHANGYE
新建Oracle 10g的服務
C:\> ORADIM -NEW -SID ZHANGYE -MAXUSERS 10 -STARTMODE AUTO -PFILE D:\Oracle10g\database\INITzhangye.ORA
7.UPGRADE選項啟動DB.
SQL> STARTUP UPGRADE
8.創建SYSAUX表空間
CREATE TABLESPACE sysaux DATAFILE 'D:\Oracle\oradata\zhangye\sysaux01.dbf'
SIZE 500M REUSE
EXTENT MANAGEMENT LOCAL
SEGMENT SPACE MANAGEMENT AUTO
ONLINE;
9.運行10g的Oracle_HOME/rdbms/admin/catupgrd.sql，然後運行utlu102s.sql查看升級結果.
SQL> SPOOL upgrade.log
SQL> @catupgrd.sql
SQL> @utlu102s.sql
SQL> SPOOL OFF
檢查upgrade.log，如果有錯誤，處理錯誤後再次運行catupgrd.sql.
10.重新啟動DB，編譯無效對象.
SQL> shutdown immediate
SQL> startup pfile=D:\Oracle10g\database\INITzhangye.ORA
SQL> @D:\Oracle10g\RDBMS\ADMIN\utlrp.sql
編譯後沒有無效對象
SQL> SELECT count(*) FROM dba_objects WHERE status='INVALID';
COUNT(*)
----------
0
升級完成.
