I already said I got a thread crossed on this one.
ASM is for the datafile and CRS files
You can use GFS, NFS and supposedly OCSF2 for the shared APPL_TOP but
I am getting mixed messages on Metalink as to what is supported for 12i 64
bit unbreakable Linux. I do have a SR open on this.

Hi Gentlemen,
Just wonder if ASM or OCFS have anything to do with Shared APPL_TOP :)
I thought those technologies are used for DB data files only on RDBMS side.
NFS or GFS might be considered as solution for shared APPL_TOP.
I have got few customers sites running NFS for shared APPL_TOP. No
significant problems at all. One think that I would like to impact
somehow is performance during maintenances procedures like running
autoconfig or generating Forms files. Does anybody in that list have
experience in improving NFS performance? I believe mounting parameters
might make a change in that area.
GFS - I have suspicions that this technology might work for shared
APPL_TOP. I would be happy to here any real live experience with using
GFS for shared APPL_TOP if somebody have in that list. If possible
please compare two solutions giving +/- es.
Thank you in advance,
Jurijs
