ORACLE修改数据库名<>


引题:在实际生产环境下我们可能需要快速的复制现有的数据库,又希望新库与原库不重名,或者我们需要复制生产库用来做研发测试,如果我们采用 DBCA 的方式,缺点是慢并且还没有数据,就需要从新导数据,费时又麻烦。下面我就详细介绍如何修改数据库名来完成使命,采用 2 种方法( 1. 重建控制文件修改数据库名 2. 使用 nid 工具修改数据库名)

一、重建控制文件修改数据库名

步骤概述

  • 生成controlfile创建脚本并写入trace文件
  • 执行查找trace文件语句,获取当前trace文件路径
  • 停掉数据库
  • 只复制数据文件、redo日志(不需要复制控制文件哦!)
  • 生成新的initLEO2.orac纯文本参数文件
  • 编辑新生成的initLEO2.ora纯文本参数文件
  • 利用initLEO2.ora纯文本参数文件创建spfileLEO2.ora二进制参数文件、
  • 数据库启动到nomount状态,加载参数文件
  • 删除原库控制文件(如果拷贝的时候包括了控制文件的话)
  • 修改/u01/app/oracle/admin/LEO/udump/leo_ora_25621.trc文件的内容

目标:我们用原库LEO复制出新库LEO2

1.生成controlfile创建脚本并写入trace文件

SYS@LEO> alter database backup controlfile to trace;

2.执行查找trace文件语句,获取当前trace文件路径

SYS@LEO> select c.value || '/' || d.instance_name || '_ora_' || to_char(a.spid,'fm99999') || '.trc' from v$process a, v$session b, v$parameter c, v$instance d<wbr></wbr>where a.addr = b.paddr and b.audsid = userenv('sessionid') and c.name = 'user_dump_dest';

Trace文件路径

C.VALUE||'/'||D.INSTANCE_NAME||'_ORA_'||TO_CHAR(A.SPID,'FM99999')||'.TRC'

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

/u01/app/oracle/admin/LEO/udump/LEO_ora_25621.trc

3.停掉数据库

SYS@LEO> shutdown immediate

Database closed.

Database dismounted.

ORACLE<wbr>instance shut down.</wbr>

4.只复制数据文件、redo日志(不需要复制控制文件哦!)

从原来的/u01/app/oracle/oradata/LEO/disk1复制到

/u01/app/oracle/oradata/LEO2/disk1

5.生成新的initLEO2.orac纯文本参数文件

export ORACLE_SID=LEO

sqlplus / as sysdba<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>进入原库执行命令

SYS@LEO> create pfile='/u01/app/oracle/product/10.2.0/db_1/dbs/initLEO2.ora' from spfile;

6.编辑新生成的initLEO2.ora纯文本参数文件

vim initLEO2.ora

需要修改的内容:

1)路径

*.audit_file_dest='/u01/app/oracle/admin/LEO2/adump'

*.background_dump_dest='/u01/app/oracle/admin/LEO2/bdump'

*.control_files='/u01/app/oracle/oradata/LEO2/disk1/control01.ctl','/u01/app/oracle/oradata/LEO2/disk2/control02.ctl','/u01/app/oracle/oradata/LEO2/disk3/control03.ctl'

*.core_dump_dest='/u01/app/oracle/admin/LEO2/cdump'

*.user_dump_dest='/u01/app/oracle/admin/LEO2/udump'

2)数据库名

*.db_name='LEO2'

7.利用initLEO2.ora纯文本参数文件创建spfileLEO2.ora二进制参数文件

export ORACLE_SID=LEO2

sqlplus / as sysdba

SYS@LEO2> create spfile from pfile;<wbr><wbr><wbr><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>创建spfile

8.数据库启动到nomount状态,加载参数文件

SYS@LEO2> startup nomount

ORACLE instance started.

INSTANCE_NAME

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

LEO2

9.删除原库控制文件(如果拷贝的时候包括了控制文件的话)

路径:

/u01/app/oracle/oradata/LEO2/disk1/control01.ctl,

/u01/app/oracle/oradata/LEO2/disk2/control02.ctl,

/u01/app/oracle/oradata/LEO2/disk3/control03.ctl

10.修改/u01/app/oracle/admin/LEO/udump/leo_ora_25621.trc文件的内容

vim<wbr></wbr>leo_ora_25621.trc

把内容拷贝到vim<wbr></wbr>test.sql临时文件中修改

定位--<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>Set #2. RESETLOGS case<wbr></wbr>位置

1)把CREATE CONTROLFILE REUSE DATABASE "LEO" RESETLOGS<wbr></wbr>NOARCHIVELOG

修改成

CREATE CONTROLFILE SET DATABASE "LEO2" RESETLOGS<wbr></wbr>NOARCHIVELOG

2)把在线日志文件和数据文件的路径中的“PROD”替换成“LEO2”,修改路径

例子:/u01/app/oracle/oradata/PROD/disk1/<wbr></wbr>替换

/u01/app/oracle/oradata/LEO2/disk1/

使用:%s#PROD#LEO2#方法替换所有“PROD

最后的完成版并执行此脚本,就完成了控制文件的创建

CREATE CONTROLFILE SET DATABASE "LEO2" RESETLOGS<wbr></wbr>NOARCHIVELOG

<wbr><wbr><wbr></wbr></wbr></wbr>MAXLOGFILES 30

11.把数据库启动到mount状态,在启动到open状态

注:必须添加resetlogs选项打开数据库,resetlogs所有以前的备份和归档日志均不可用

注:当我们执行完控制文件创建脚本后,数据库就已经是mount状态了。

11.新建LEO2密码文件

orapwd file=orapwLEO2 password=oracle entries=30

<wbr></wbr>

二、使用nid工具修改数据库名

Nidoracle软件提供的一个小工具,可以修改数据库名称,位置:$ORACLE_HOME/bin/

优点:可以不用重建控制文件就修改数据库名

步骤概述

  • 验证当前数据库名,实例名,服务名参数
  • 停掉数据库
  • 数据库启动到mount状态,nid工具在mount状态下才能用,直接修改控制文件内容
  • 生成新的initLEO3.orac纯文本参数文件并修改数据库名
  • 利用initLEO3.ora纯文本参数文件创建spfileLEO3.ora二进制参数文件
  • 创建转储目录
  • 启动数据库到open状态
  • 检查当前数据库名,实例名,服务名参数
  • 新建LEO3密码文件
  • 修改listener.oratnsnames.ora文件内容

目标:我们用原库LEO2修改成新库LEO3,还用原来的控制文件、数据文件、在线日志

1.验证当前数据库名,实例名,服务名参数

4.生成新的initLEO3.orac纯文本参数文件并修改数据库名和路径

SYS@LEO2> create pfile='/u01/app/oracle/product/10.2.0/db_1/dbs/initLEO3.ora' from spfile;

vim<wbr></wbr>initLEO3.ora

1)路径

*.audit_file_dest='/u01/app/oracle/admin/LEO3/adump'

*.background_dump_dest='/u01/app/oracle/admin/LEO3/bdump'

*.control_files='/u01/app/oracle/oradata/LEO3/disk1/control01.ctl','/u01/app/oracle/oradata/LEO2/disk2/control02.ctl','/u01/app/oracle/oradata/LEO3/disk3/control03.ctl'

*.core_dump_dest='/u01/app/oracle/admin/LEO3/cdump'

*.user_dump_dest='/u01/app/oracle/admin/LEO3/udump'

2)数据库名

*.db_name='LEO3'

5.利用initLEO3.ora纯文本参数文件创建spfileLEO3.ora二进制参数文件

SYS@LEO2> create spfile='/u01/app/oracle/product/10.2.0/db_1/dbs/spfileLEO3.ora' from pfile='/u01/app/oracle/product/10.2.0/db_1/dbs/initLEO3.ora';

6.创建转储目录

mkdir -p $ORACLE_BASE/admin/LEO3/adump

mkdir -p $ORACLE_BASE/admin/LEO3/bdump

mkdir -p $ORACLE_BASE/admin/LEO3/cdump

mkdir -p $ORACLE_BASE/admin/LEO3/udump

7.直接启动数据库到open状态

注:必须添加resetlogs选项打开数据库,resetlogs所有以前的备份和归档日志均不可用

export ORACLE_SID=LEO3

sqlplus / as sysdba

SYS@LEO3> startup

ORACLE instance started.
