Since Oracle 10g Release 2 was released earlier than rhel5.4, the official Oracle documentation does not provide the 10gr2 installation manual on rhel5.4. I will write a separate article on installing 10gr2 on rhel5.4, this document describes how to delete database software. In fact, the idea is simple: Delete the relevant files. There are two methods: manual deletion on the Character interface and deletion on the GUI through oui. This article only describes manual deletion on the Character interface.
Perform the following operations:
1. Delete all content under ORACLE_HOME: Rm-RF $ ORACLE_HOME
2. rm-RF/etc/ora *
3. rm-RF/path/to/Your/orainventory
4. And there are some binaries in/usr/local/bin/(by default ):
Rm-F/usr/local/bin/coraenv
Rm-F/usr/local/bin/oraenv
Rm-F/usr/local/bin/dbhome
Can also see this post: http://forums.oracle.com/forums/thread.jspa? Threadid = 266762. This section describes the corresponding operations in windows. This: http://perumal.org/removing-oracle-10g-software-from-linux-server/
