How to Relink Oracle 12CR2 Grid Infrastrure ( GI ) Binary

1)Change ownership of some root owned files like extjobO and jssuO, etc, because the relink script will be run as “grid’ user to change the file permissions.

chmod 600 /u01/app/ )
chmod 700 /u01/app/
chmod 600 /u01/app/ )

2) As root user:


#cd /u01/app/
# ./ -unlock

3) As grid user:

$ cd /u01/app/
$ relink
writing relink log to: /u01/app/

-- Check any errors ?
$ grep -i error /u01/app/

4) As root user:

# cd /u01/app/
# ./

# cd /u01/app/
# ./ -lock
Using configuration parameter file: /u01/app/
