Enabling Oracle ACFS on Oracle Restart Configurations
You must enable root access to use Oracle ACFS.
To enable root access, log in as 
               
               root, navigate to the path Grid_home/crs/install, and run the script roothas.sh —lockacfs. For example:
               # cd /u01/app/oracle/product/12.2.0/grid/crs/install
# roothas.sh -lockacfsNote:
Starting with Oracle Database 12c Release 1 (12.1.0.2), theroothas.sh script replaces the roothas.pl script in the Oracle Grid Infrastructure home.
