If your purpose is to have a shared disk for Oacle EBS Apps Tier installation, then we are talking about a Shared Application Filesystem.

In order to build such an environment, Cluster filesystem is not a must. You can build such a configuration even with NFS..

In this types of configurations, I see mostly NFS is utilized rather OCFS or any other shared filesystem.

First, shared Appl_top using NFS is completely supported and documented.  The Oracle EBS system supports shared Application Filesystem terminology starting from application version 11i, and it’s supported until 12.2. It is easy to build and use.
Ofcourse, there are some points to be considered :

The sharing of APPL_TOP in a Windows environment is not supported.
INST_TOP also will be in shared locations unlike earlier releases.
All application tiers sharing the file system should be running on the same operating system.
Shared application tier file systems should be in read-write mode on all application tiers.

Please read : Sharing The Application Tier File System in Oracle E-Business Suite Release 12.2 (Doc ID 1375769.1)
