Deinstall Oracle 11gR2 windows

Somebody thinking This is simple one How do we deinstall Oracle Software. Then Why this post need? Yes. the previous release oracle software version like 10g  or less than, you can click on Oracle Universal Installer Page and then choose deinstall product and clicked what you want remove, you can easily. But now you cannot deinstall using Oracle universal Installer, It something different , See below when i try remove Oracle 11g product using OUI.

Okay.Now I’m going to deinstall the oracle product at using the picture mentioned path,

 C:\app\mazar\product\11.2.0\dbhome_1\deinstall\deinstall        Enter

But it showing some permissions issues and also It’s recommand, you should go to download Oracle Deinstall software from OTN.

Now I have plan to download this product from OTN, from here

http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-win32soft-098987.html

After downloaded it, I just unzip this file ,After extracted I go to deinstall folder and then again I run it deinstall, but it shows following message,

C:\Users\mazar>cd C:\software\oracle11gr2\win32_11gR2_deinstall\deinstall

C:\software\oracle11gr2\win32_11gR2_deinstall\deinstall>deinstall

C:\softwarbat -home <Complete path of Oracle home>
               [ -silent ]
               [ -checkonly ]
               [ -local ]
               [ -paramfile <complete path of input parameter properties file> ]
               [ -params <name1=value[ name2=value name3=value …]> ]
               [ -o <complete path of directory for saving files> ]
               [ -help | -h: Type -h or -help to get more information on each of the above options. ]

Tool is being run outside the Oracle Home, -home needs to be set.

C:\software\oracle11gr2\win32_11gR2_deinstall\deinstall>

So We need to set Oracle 11g home path here ,and then you can deinstall easily

C:\software\oracle11gr2\win32_11gR2_deinstall\deinstall>deinstall -home C:\app\mazar\product\11.2.0\dbhome_1
Location of logs C:\Program Files\Oracle\Inventory\logs\
