Let me just preface this by saying that I work at Oracle, but not in the Database or in OCFS2...

I don't know the answer offhand, but the user guide can be found here (http://oss.oracle.com/projects/ocfs2/dist/documentation/ocfs2_users_guide.pdf) and chop that address down to just the oss.oracle.com to find general information about all of Oracle's Open Source endeavors.

Considering that they support Oracle running on OCFS2 (as well as shared root), I doubt this would be a problem in either case. As for the mysql question, I'm not sure that Larry would be too happy with someone running mysql on top of OCFS2. Not that I expect you to consider it, but there is a "lite" version of Oracle DB that's free called Express Edition (http://www.oracle.com/technology/products/database/xe/index.html). Exactly how scaled back it is, I have no idea, but its Oracle DB and free - that's at least something. > Could we setup a cluster of nodes which all read and write from the database > stored on such a FS? This would be more a database issue (locking and so forth), but yea. -- [email protected] mailing list
