I check the permission for Grid Home/bin/oracle binary file

[oracle@node1 ~]$ ls -l /u02/app/11.2.0/grid/bin/oracle
-rwxrwxr-x oracle dba 210824714 June 30 09:00 /u02/app/11.2.0/grid/bin/oracle


Stop the ASM instance and then execute following command

[oracle@node1 ~]$ chmod 6751 /u02/app/11.2.0/grid/bin/oracle
[oracle@node1 ~]$ ls -l /u02/app/11.2.0/grid/bin/oracle
-rwsr-s–x 1 oracle dba 210824714 July 30 09:02 /u02/app/11.2.0/grid/bin/oracle

By Changing the permission on second node grid home oracle binary file .

Start the ASM instance and then tried to create the database using DBCA. It was successful.
