How to clear CRS/RAC for 10/11g
#!/bin/sh
#=============================================================================#
# #
# This script is used to fully delete Software of CRS/RAC for 10/11g #
# Delete CRS/RAC SW, CRS related socket/temp/init files #
# And change back ownership of OCR and VF #
# #
# Right now, it is only tested on AIX and Linux #
# #
# warren.xu@oracle.com #
#=============================================================================#
# ------------------------- Change Logs --------------------
#
# 12/13/2007 - Creation and Test for AIX Platform
# 01/03/2008 - Add Platform Variables for Linux/HP/SUN
# 01/05/2008 - Change and Test for Linux Platform
# 01/07/2008 - Delete SW on all cluster nodes if possible
#
# ----------------------------- End ------------------------
