通常情况下，Oracle数据库安装之后是不会轻易的删除的。但是当我们进行日常实验或者软件故障问题调整时，是需要进行Database Server或者Client删除的。

 

删除Oracle软件（主要是$ORACLE_HOME目录下内容）主要有两种方式，一种是使用内置在Oracle安装目录下的deinstall工具脚本。其调用路径分别为：

 

 

    $ORACLE_HOME/deinstall/deinstall       (unix platforms)

    %ORACLE_HOME%\deinstall\deinstall.bat   (windows platforms)

 

 

另一种方法是使用专门的deinstall工具进行删除操作。该工具在Oracle官方网站上可以单独的下载。

 

这两种方式上，Oracle官方推荐的做法是使用后者，也就是专门的删除工具。原因是内置的deinstall工具脚本中常常带有很多bug，很多时候不能完全的将其删除干净。特别是Windows环境下的卸载工具，不能正常工作的场景很多。

 

本篇就来一步步的介绍使用deinstall卸载方法。

 

1、  环境介绍

 

首先看看我们的实验环境，是Linux 4下的Oracle 11g。其中配置了完整的安装路径变量。

 

--环境变量信息

[oracle@oracle11g ~]$ env | grep ORA

ORACLE_SID=wilson

ORACLE_BASE=/u01

ORACLE_HOME=/u01/oracle

 

 

首先，使用lsnrctl stop命令，将监听程序停止工作。使用status参数进行确认。

 

--检验监听器状态

[oracle@oracle11g ~]$ lsnrctl status

 

LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 18-NOV-2011 22:46:52

Copyright (c) 1991, 2009, Oracle.  All rights reserved.

 

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=oracle11g)(PORT=1521)))

TNS-12541: TNS:no listener

 TNS-12560: TNS:protocol adapter error

  TNS-00511: No listener

   Linux Error: 111: Connection refused

 

 

关闭数据库服务器。

 

 

[oracle@oracle11g ~]$ sqlplus /nolog

 

SQL*Plus: Release 11.2.0.1.0 Production on Fri Nov 18 22:47:02 2011

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

 

SQL> conn / as sysdba

Connected.

SQL> shutdown immediate

Database closed.

Database dismounted.

ORACLE instance shut down.

 

 

确定oracle相关进程全部停止。

 

 

[oracle@oracle11g ~]$ ps -ef | grep ora

root      5572  5540  0 22:43 pts/0    00:00:00 su - oracle

oracle    5573  5572  0 22:43 pts/0    00:00:00 -bash

oracle    5775  5573  0 22:47 pts/0    00:00:00 ps -ef

oracle    5776  5573  0 22:47 pts/0    00:00:00 grep ora

 

 

2、上传和解压deinstall程序

 

使用FTP客户端，将下载的内容上传到Linux目录上。

 

 

[oracle@oracle11g test]$ ls -l

total 111264

-rw-r--r--  1 root root 113811593 Nov 18 22:56 linux_11203_deinstall.zip

 

 

使用unzip进行解压文件。

 

 

[oracle@oracle11g test]$ unzip linux_11203_deinstall.zip

Archive:  linux_11203_deinstall.zip

   creating: deinstall/

  inflating: deinstall/deinstall.pl 

   creating: deinstall/sysman/

   creating: deinstall/sysman/admin/

  inflating: deinstall/sysman/admin/supportedtzs.lst 

  inflating: deinstall/sysman/admin/nsupportedtzs.lst 

   creating: deinstall/sysman/admin/dtds/

  inflating: deinstall/sysman/admin/dtds/tagsize.properties 

   creating: deinstall/sysman/admin/scripts/

（篇幅原因，有省略……）

 

 

进入deinstall目录。使用deinstall是不需要额外的安装过程的。

 

 

[oracle@oracle11g test]$ ls -l

total 111268

drwxr-xr-x  20 oracle oinstall      4096 Sep 22 14:24 deinstall

-rw-r--r--   1 root   root     113811593 Nov 18 22:56 linux_11203_deinstall.zip

 

[oracle@oracle11g deinstall]$ ls

assistants    cv            deinstall.xml  lib       perl        sshUserSetup.sh

bin           dc_ocm        diagnostics    logs      readme.txt  sysman

bootstrap.pl  deinstall     jlib           mapfiles  response    usm

crs           deinstall.pl  jre            oui       srvm        utl

 

 

3、调用脚本语句

 

调用语句，删除指定的$ORACLE_HOME。

 

--指定删除的$ORACLE_HOME

[oracle@oracle11g deinstall]$ ./deinstall -home /u01/oracle

Location of logs /test/deinstall/./logs/

4、结论

 

删除数据库是一种非经常性场景，但是预先准备，可以做到有备无患。
