I didn't got the point here as is that mean I can install Oracle
clusterware. Actually I have one Veritas cluster environment where I
have two database server in Active Passive mode with Shared Storage. I
am looking on some hint as if Veritas Cluster environment can be changed
with such solution.

...it is just an API, but sure, you can cobble this together. Ready,
begin...you're starting
from scratch
