Deinstall and cleanup Oracle 11g RAC instance

Deinstall and Clean-up  11g RAC installaton:


1) Shutdown all the DB and cluster services on all the RAC node
From root:
crsctl stop cluster -all
and
crsctl stop crs  on both node



2) From Oracle User:

Run the below:

soatsdb1.com[GSOATS1]$ cd /opt/oracle/grid/11.2.0/deinstall

soatsdb1.com[GSOATS1]$ ls
bootstrap.pl  deinstall  deinstall.pl  deinstall.xml  jlib  readme.txt  response  sshUserSetup.sh
