Oracle11g修改实例名和数据库名

参考博客http://blog.itpub.net/26870952/viewspace-2151994/，经过试验，做了一些补充和完善
分为两个阶段，第一阶段修改实例名sid；第二阶段修改数据库名dbname
将原先的实例名orcl 更改为 isdms
将原先的数据库名orcl 更改为 isdms

第一阶段：修改实例名sid

1、登录数据库查看先前的sid

（1）切换到oracle用户

[root@brms03 ~]# su - oracle
Last login: Mon Dec 10 11:35:21 CST 2018
[oracle@brms03 ~]$

（2）打开已经启动数据库并查看sid

[oracle@brms03 ~]$ sqlplus / as sysdba

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> select instance from v$thread;

INSTANCE
--------------------------------------------------------------------------------
orcl

SQL> 

2、关闭数据库

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> exit
Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

3、修改/etc/oratab文件

编辑文件/etc/oratab，将文件里面的orcl换成isdms

[oracle@brms03 ~]$ vim /etc/oratab

4、修改.bash_profile文件

编辑oracle用户的 .bash_profile文件,把orcl改成isdms

[oracle@brms03 ~]$ vim ~/.bash_profile

修改之后使文件生效

[oracle@brms03 ~]$ source ~/.bash_profile

查看环境变量，确定修改已经生效

[oracle@brms03 ~]$ env|grep ORACLE
ORACLE_SID=isdms
ORACLE_BASE=/opt/oracle
ORACLE_HOME=/opt/oracle/112

5、修改dbs目录下的文件名

dbs目录是用于存放数据库服务器端的参数文件Spfile、初始化文件init、还有密码文件orapw$ORACLE_SID
在$ORACLE_HOME目录下

[oracle@brms03 dbs]$ cd $ORACLE_HOME/dbs
[oracle@brms03 dbs]$ ll
total 20
-rw-rw----. 1 oracle oinstall 1544 Dec 12 16:48 hc_orcl.dat
-rw-r--r--. 1 oracle oinstall 2851 May 16  2009 init.ora
-rw-r-----. 1 oracle oinstall   24 Sep 10 14:13 lkORCL
-rw-r-----. 1 oracle oinstall 1536 Oct  8 17:23 orapworcl
-rw-r-----. 1 oracle oinstall 2560 Dec 10 11:35 spfileorcl.ora
[oracle@brms03 dbs]$ mv hc_orcl.dat hc_isdms.dat
[oracle@brms03 dbs]$ mv lkORCL lkISDMS
[oracle@brms03 dbs]$ mv spfileorcl.ora spfileisdms.ora 
[oracle@brms03 dbs]$ ll
total 20
-rw-rw----. 1 oracle oinstall 1544 Dec 12 16:48 hc_isdms.dat
-rw-r--r--. 1 oracle oinstall 2851 May 16  2009 init.ora
-rw-r-----. 1 oracle oinstall   24 Sep 10 14:13 lkISDMS
-rw-r-----. 1 oracle oinstall 1536 Oct  8 17:23 orapworcl
-rw-r-----. 1 oracle oinstall 2560 Dec 10 11:35 spfileisdms.ora

重新生成密码文件，并将旧的密码文件删除

[oracle@brms03 dbs]$ orapwd file=$ORACLE_HOME/dbs/oraw$ORACLE_SID password=sys entries=5 force=y
[oracle@brms03 dbs]$ ll
total 24
-rw-rw----. 1 oracle oinstall 1544 Dec 12 16:48 hc_isdms.dat
-rw-r--r--. 1 oracle oinstall 2851 May 16  2009 init.ora
-rw-r-----. 1 oracle oinstall   24 Sep 10 14:13 lkISDMS
-rw-r-----. 1 oracle oinstall 1536 Oct  8 17:23 orapworcl
-rw-r-----  1 oracle oinstall 2048 Dec 12 17:09 orawisdms
-rw-r-----. 1 oracle oinstall 2560 Dec 10 11:35 spfileisdms.ora
[oracle@brms03 dbs]$ rm -rf orapworcl 
[oracle@brms03 dbs]$ ll
total 20
-rw-rw----. 1 oracle oinstall 1544 Dec 12 16:48 hc_isdms.dat
-rw-r--r--. 1 oracle oinstall 2851 May 16  2009 init.ora
-rw-r-----. 1 oracle oinstall   24 Sep 10 14:13 lkISDMS
-rw-r-----  1 oracle oinstall 2048 Dec 12 17:09 orawisdms
-rw-r-----. 1 oracle oinstall 2560 Dec 10 11:35 spfileisdms.ora

6、登录启动数据库，查看实例名字

修改成功，实例名已经由orcl变成isdms

[oracle@brms03 dbs]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Wed Dec 12 17:14:13 2018

Copyright (c) 1982, 2009, Oracle.  All rights reserved.

Connected to an idle instance.

SQL> startup
ORACLE instance started.

SQL> select instance from v$thread;

INSTANCE
--------------------------------------------------------------------------------
isdms

第二阶段：修改数据库名dbname

不用退出登录，接着开始修改数据库名dbname

1、备份控制文件，并关闭退出数据库

SQL> alter database backup controlfile to trace resetlogs;  

Database altered.

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> exit
Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

2、根据旧的控制文件生成修改更新控制文件的sql语句

进入控制文件的备份目录，根据alter_orcl.log找到控制备份文件
oracle11.2g 的控制文件备份目录为：$ORACLE_BASE/diag/rdbms/orcl/isdms/trace

[oracle@brms03 trace]$ cd $ORACLE_BASE/diag/rdbms/orcl/isdms/trace
[oracle@brms03 trace]$ vim alert_isdms.log

在alert_isdms.log文件中找到contolfile的备份trc
Backup controlfile written to trace file /opt/oracle/diag/rdbms/orcl/isdms/trace/isdms_ora_27000.trc
复制一份进行修改：

[oracle@brms03 trace]$ cp /opt/oracle/diag/rdbms/orcl/isdms/trace/isdms_ora_27000.trc isdms.sql

编辑文件isdms.sql
1）查找STARTUP NOMOUNT语句，将这一行上面的所有行都删除
2）将-- End of tempfile additions.语句下面的行全部删除
3）查找所有以–开始的行，把这些行删除
4）查找所有的orcl修改为isdms，所有的ORCL修改为ISDMS
5）找到CREATE CONTROLFILE REUSE DATABASE…语句，将其中的REUSE修改为SET
6）找到RECOVER DATABASE USING BACKUP CONTROLFILE语句，将其用双横线（–）注释掉

最终isdms.sql文件如下：

STARTUP NOMOUNT
CREATE CONTROLFILE SET DATABASE "ISDMS" RESETLOGS  NOARCHIVELOG
    MAXLOGFILES 16
    MAXLOGMEMBERS 3
    MAXDATAFILES 100
    MAXINSTANCES 8
    MAXLOGHISTORY 2336
LOGFILE
  GROUP 1 '/opt/oracle/oradata/isdms/redo01.log'  SIZE 50M BLOCKSIZE 512,
  GROUP 2 '/opt/oracle/oradata/isdms/redo02.log'  SIZE 50M BLOCKSIZE 512,
  GROUP 3 '/opt/oracle/oradata/isdms/redo03.log'  SIZE 50M BLOCKSIZE 512
DATAFILE
  '/opt/oracle/oradata/isdms/system01.dbf',
  '/opt/oracle/oradata/isdms/sysaux01.dbf',
  '/opt/oracle/oradata/isdms/undotbs01.dbf',

  '/opt/oracle/oradata/isdms/isdms_01.dbf',
  '/opt/oracle/oradata/isdms/dwd_produce_01.dbf',
  '/opt/oracle/oradata/isdms/dwd_produce_02.dbf',
  '/opt/oracle/oradata/isdms/dwd_produce_03.dbf',
  '/opt/oracle/oradata/isdms/isdms_xz.dbf'
CHARACTER SET AL32UTF8
;
--RECOVER DATABASE USING BACKUP CONTROLFILE
ALTER DATABASE OPEN RESETLOGS;
ALTER TABLESPACE TEMP ADD TEMPFILE '/opt/oracle/oradata/isdms/temp01.dbf'
     SIZE 1504M REUSE AUTOEXTEND ON NEXT 655360  MAXSIZE 32767M;

3、生成配置文件

[oracle@brms03 oracle]$ sqlplus  / as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Wed Dec 12 18:59:07 2018

Copyright (c) 1982, 2009, Oracle.  All rights reserved.

Connected to an idle instance.

SQL> create pfile   from spfile;

File created.

SQL> exit
Disconnected

最终生成的文件在$ORACLE_HOME/dbs目录下文件名为init$ORACLE_SID.ora
在本示例中为：initisdms.ora

[oracle@brms03 dbs]$ ll
total 28
-rw-rw----. 1 oracle oinstall 1544 Dec 12 17:17 hc_isdms.dat
-rw-r--r--  1 oracle oinstall 1265 Dec 12 18:59 initisdms.ora
-rw-r--r--. 1 oracle oinstall 2851 May 16  2009 init.ora
-rw-r-----. 1 oracle oinstall   24 Sep 10 14:13 lkISDMS
-rw-r-----  1 oracle oinstall   24 Dec 12 17:14 lkORCL
-rw-r-----  1 oracle oinstall 2048 Dec 12 17:09 orawisdms
-rw-r-----. 1 oracle oinstall 3584 Dec 12 17:14 spfileisdms.ora

4、目录和文件更改

-rw-r--r--. 1 oracle oinstall 2851 May 16  2009 init.ora
-rw-r-----. 1 oracle oinstall   24 Sep 10 14:13 lkISDMS
-rw-r-----  1 oracle oinstall   24 Dec 12 17:14 lkORCL
-rw-r-----  1 oracle oinstall 2048 Dec 12 17:09 orawisdms

4.6 修改监听的配置文件tnsnames.ora

监听配置文件目录：$ORACLE_HOME/network/admin
修改文件内容，将orcl替换成isdms，ORCL替换成ISDMS

[oracle@brms03 admin]$ cd $ORACLE_HOME/network/admin
[oracle@brms03 admin]$ ll
total 20
-rw-r--r--. 1 oracle oinstall  343 Sep 10 14:11 listener.ora

-rw-r-----. 1 oracle oinstall  301 Sep 10 14:14 tnsnames.ora
[oracle@brms03 admin]$ vim tnsnames.ora 

修改前文件内容：

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = brms03)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

修改之后的文件内容：

ISDMS =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = brms03)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = isdms)
    )
  )

5、调用前面步骤修改好的isdms.sql，目的是生成链接控制文件等
