Now that the current configuration is saved, let's dare to change it. The script
rootdelete.sh
removes CRS entries from
/etc/inittab
, notifies
init
of the changes, removes files from
/etc/
init.d
as well as
/etc/rc[0-6].d
, and deletes
/etc/oracle/scls_scr
while retaining
/etc/
oracle/ocr.loc
. In case CRS is running in the endless loop mentioned before, kill the shell
scripts that were called with the argument
startcheck
by
init.cssd
. Otherwise stop CRS with
crsctl
stop
crs
and then run
rootdelete.sh
as root.
