How To Deinstall Oracle Home In 11GR2?
=======================================

Oracle Deinstall Utility - 11g R2

Starting with Oracle Database 11g Release 2 (11.2.0.1.0), a separate deinstallation and deconfiguration tool is available as a separate download. The deinstall tool is for deinstalling the 11.2 software. This tool can be used to deinstall an Oracle Grid Infrastructure home, Oracle Real Application Clusters (Oracle RAC) database homes, single-instance databases, database clients, and Oracle Grid Infrastructure for standalone server homes.

The deinstall tool is also installed by default when installing an Oracle 11.2 home. The deinstall tool has built-in intelligence to check for installed software, and access the files that it needs to complete the deinstallation. If the tool detects missing files, it prompts you to download a standalone version of the deinstall tool to complete a deinstallation successfully.
