我修改后的ccf.sql文件内容如下

STARTUP NOMOUNT

MAXLOGFILES 16

MAXLOGMEMBERS 3

MAXDATAFILES 100

MAXINSTANCES 8

2.7、修改数据文件、在线日志文件名

如果上一步修改了ccf.sql文件中的datafile和logfile段的文件名，这里要将这些文件名重命令为与其一致。

因为我的实验环境使用了ASM，在Oracle 10.2中ASM中不能重命名和复制文件，我采用了创建别名的方式，操作如下：

oracle@oracle[/oracle/admin/cnhtm/udump]> export ORACLE_SID=+ASM

oracle@oracle[/oracle/admin/cnhtm/udump]> sqlplus / as sysdba

SQL*Plus: Release 10.2.0.1.0 - Production on Sun Dec 20 12:08:52 2009

Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production

With the Partitioning, OLAP and Data Mining options

idle> alter diskgroup data add directory '+data/CNHTM';

Diskgroup altered.

idle> alter diskgroup data add directory '+data/CNHTM/DATAFILE';

Diskgroup altered.

idle> alter diskgroup data add alias

2 '+data/CNHTM/DATAFILE/EXAMPLE01.DBF'

3 for

4 '+data/ORCL/DATAFILE/EXAMPLE.261.705922745';

Diskgroup altered.

......

idle> alter diskgroup data add alias

2 '+data/CNHTM/DATAFILE/USERS01.DBF'

3 for

4 '+data/ORCL/DATAFILE/USERS.266.705922777';

Diskgroup altered.

idle> alter diskgroup data add directory '+data/CNHTM/ONLINELOG';

Diskgroup altered.

......

idle> alter diskgroup data add alias

2 '+data/CNHTM/ONLINELOG/group_4.LOG'

3 for

4 '+data/ORCL/ONLINELOG/group_7.273.705923695';

Diskgroup altered.

2.8、如果归档日志目录名中包含sid，那么修改归档目录名

我的测试环境，归档目录使用的是flash_recovery_area，所以需要将这个目录中的ORCL目录重命名为CNHTM

2.9、使用spfile生成pfile

注意这里没有启动数据库，只是链接到idle状态

oracle@oracle[/home/oracle]> export ORACLE_SID=cnhtm

oracle@oracle[/home/oracle]> sqlplus / as sysdba

SQL*Plus: Release 10.2.0.1.0 - Production on Sun Dec 20 11:49:20 2009

Copyright (c) 1982, 2005, Oracle. All rights reserved.

Connected to an idle instance.

idle> create pfile='?/dbs/initcnhtm.ora' from spfile;

File created.

idle> exit

Disconnected from Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production

With the Partitioning, OLAP and Data Mining options

2.10、进入$ORACLE_HOME/dbs目录

2.11、编辑initcnhtm.ora文件

搜索所有的orcl，重命令为cnhtm，搜索所有的ORCL，重命名为CNHTM

2.12、删除控制文件

将原来的控制文件删除或重命名

控制文件的位置名称可以通过查看2.11步骤中的*.control_files来确定

如果控制文件在ASM中，可以进入asmcmd命令，然后用rm命令删除

2.13、进入$ORACLE_BASE/admin目录

将orcl目录重命名为cnhtm

2.14、使用修改过的pfile生成spfile

oracle@oracle[/oracle/admin/cnhtm/udump]> sqlplus / as sysdba

SQL*Plus: Release 10.2.0.1.0 - Production on Sun Dec 20 11:59:56 2009

Copyright (c) 1982, 2005, Oracle. All rights reserved.

Connected to an idle instance.

idle> create spfile from pfile='?/dbs/initcnhtm.ora';

File created.

2.15、调用2.6步骤修改好的ccf.sql

idle> @/oracle/admin/cnhtm/udump/ccf.sql

ORACLE instance started.

Total System Global Area 167772160 bytes

Fixed Size 1218292 bytes

Variable Size 67111180 bytes

Database Buffers 92274688 bytes

Redo Buffers 7168000 bytes

Control file created.

Database altered.

Database altered.

Tablespace altered.

2.16、检查数据库状态

idle> conn / as sysdba

Connected.

sys@CNHTM>select open_mode from v$database;

OPEN_MODE

----------

READ WRITE

sys@CNHTM> show parameter name

NAME TYPE VALUE

------------------------------------ ----------- ------------------------------

db_file_name_convert string

db_name string cnhtm

db_unique_name string cnhtm

global_names boolean FALSE

instance_name string cnhtm

lock_name_space string

log_file_name_convert string

service_names string cnhtm

发现数据库名(db_name)已经修改为cnhtm
