使用Deinstall专用工具删除Oracle Database

發布時間：2025/3/19 编程问答 21 豆豆

生活随笔收集整理的這篇文章主要介紹了使用Deinstall专用工具删除Oracle Database 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

通常情況下，Oracle數據庫安裝之后是不會輕易的刪除的。但是當我們進行日常實驗或者軟件故障問題調整時，是需要進行Database Server或者Client刪除的。

刪除Oracle軟件（主要是$ORACLE_HOME目錄下內容）主要有兩種方式，一種是使用內置在Oracle安裝目錄下的deinstall工具腳本。其調用路徑分別為：

????$ORACLE_HOME/deinstall/deinstall??????(unix platforms)

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

?另一種方法是使用專門的deinstall工具進行刪除操作。該工具在Oracle官方網站上可以單獨的下載。

這兩種方式上，Oracle官方推薦的做法是使用后者，也就是專門的刪除工具。原因是內置的deinstall工具腳本中常常帶有很多bug，很多時候不能完全的將其刪除干凈。特別是Windows環境下的卸載工具，不能正常工作的場景很多。

本篇就來一步步的介紹使用deinstall卸載方法。

1、?環境介紹

首先看看我們的實驗環境，是Linux 4下的Oracle11g。其中配置了完整的安裝路徑變量。

--環境變量信息

[oracle@oracle11g~]$ env | grep ORA

ORACLE_SID=wilson

ORACLE_BASE=/u01

ORACLE_HOME=/u01/oracle

首先，使用lsnrctl stop命令，將監聽程序停止工作。使用status參數進行確認。

--檢驗監聽器狀態

[oracle@oracle11g~]$ lsnrctl status

LSNRCTL for Linux: Version11.2.0.1.0 - Production on 18-NOV-2011 22:46:52

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

關閉數據庫服務器。

[oracle@oracle11g~]$ sqlplus /nolog

SQL*Plus: Release11.2.0.1.0 Production on Fri Nov 18 22:47:02 2011

SQL> conn / as sysdba

Connected.

SQL>shutdown immediate

Database closed.

Database dismounted.

ORACLE instance shut down.

確定oracle相關進程全部停止。

[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、上傳和解壓deinstall程序

使用FTP客戶端，將下載的內容上傳到Linux目錄上。

[oracle@oracle11gtest]$ ls -l

total 111264

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

使用unzip進行解壓文件。?

[oracle@oracle11gtest]$ 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……）

進入deinstall目錄。使用deinstall是不需要額外的安裝過程的。

[oracle@oracle11gtest]$ 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@oracle11gdeinstall]$ 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、調用腳本語句

調用語句，刪除指定的$ORACLE_HOME。

--指定刪除的$ORACLE_HOME

[oracle@oracle11gdeinstall]$./deinstall -home /u01/oracle

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

############ ORACLE DEINSTALL & DECONFIG TOOL START ############

在腳本運行中，會有若干的確認點，確認刪除的對象、監聽器的名稱等信息。通常都會有默認值。
