A requirement has arrived where writing/updating/deleting multiple files on a file system must occur atomically.
The disk is NFS mounted across all nodes in the cluster. Each node needs to be able to write to disk in order to achieve load balancing.
1) Can anyone comment on how to make the FileResourceManager safely coordinate with multiple JVMs all accessing the same directory ?
2) If #1 is possible, then it would surely be possible to write a JCA adapter so these disk writes could occur in a distributed transaction along with a DB write & JMS message publish.
Any thoughts?
