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.
SQL> @d:utlu102i.sql;

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(*)
----------
0
升级完成.
