Now reboot the system - recompile VirtualBox guest Additions and restart CRS

# reboot

Rebuild Virtualbox Guest Additions 
# /etc/init.d/vboxadd setup
# reboot 

--> Relink Oracle CRS and RDBMs binaries [ using the relink command ] 

Re-enable and restart CRS
# crsctl enable crs
# crsctl start crs

  1. Hi Abdul,
    yes your are right. I have added a short comment on this
    You should relink the Oracle kernel even in my case it worked without relinking.

  2. If you upgrade or patch the operating system on which the Oracle software is installed, you will have to manually relink the Oracle software.
  3. If you want to enable or disable certain Oracle database features, you will have to relink the Oracle software.
