1.安装oracle 10g r2的软件

2.打oracle 10g最新的补丁，我打的是升级到10.2.0.2的补丁

3.运行Pre-Upgrade Information Tool.它用来分析升级到10g前你要做的一些操作，比如需要增加或减少的参数等.

启动要升级的DB，用SYSDBA运行10g的ORACLE_HOME/rdbms/admin下的utlu102i.sql，查看产生的日志.

SQL> SPOOL info.log

SQL> @utlu102i.sql

SQL> SPOOL OFF

下面是我的info.log.

copy oracle 9i的pfile(D:oracleora92databaseINITzhangye.ORA)到oracle 10g的pfile(D:oracle10gdatabaseINITzhangye.ORA).

检查info.log，对oracle 10g的pfile修改.

4.运行Oracle Net Configuration Assistant，生成10g的listener.ora

5.rman备份DB.

6.stop所有oracle 9i的服务.

删除oracle 9i的服务.

C:> ORADIM -DELETE -SID ZHANGYE

新建oracle 10g的服务

C:> ORADIM -NEW -SID ZHANGYE -MAXUSERS 10 -STARTMODE AUTO -PFILE D:oracle10gdatabaseINITzhangye.ORA

7.UPGRADE选项启动DB.

SQL> STARTUP UPGRADE

8.创建SYSAUX表空间

CREATE TABLESPACE sysaux DATAFILE 'D:oracleoradatazhangyesysaux01.dbf'

SIZE 500M REUSE

EXTENT MANAGEMENT LOCAL

SEGMENT SPACE MANAGEMENT AUTO

ONLINE;

9.运行10g的ORACLE_HOME/rdbms/admin/catupgrd.sql，然后运行utlu102s.sql查看升级结果.

SQL> SPOOL upgrade.log

SQL> @catupgrd.sql

SQL> @utlu102s.sql

SQL> SPOOL OFF

检查upgrade.log，如果有错误，处理错误后再次运行catupgrd.sql.

10.重新启动DB，编译无效对象.

SQL> shutdown immediate

SQL> startup pfile=D:oracle10gdatabaseINITzhangye.ORA

SQL> @D:oracle10gRDBMSADMINutlrp.sql

编译后没有无效对象

SQL> SELECT count(*) FROM dba_objects WHERE status='INVALID';

COUNT(*)

----------

升级完成.
