**************************************** Step By Step Analysis ******************************************************

#########################################
# 1) Folder Overview
#########################################

We have created new database with name RACDB01. But later on we need to create the same database with Different name. So We have used DBCA in silent mode to remove the database.
RAC Database and its instances was removed from OCR, but the database file which are present in ASM didn't get removed. so we are manually removing the directories as its not needed anymore.
