More on WebSphere 6.0 and shared file systems

It's worth pointing out what may be obvious to some but not to others. If you are putting transaction logs on a shared file system then make sure you configure it to do write through, no caching. It must be capable of ensuring that when WebSphere tells the file system to flush, the change goes all the way through to storage and doesn't get buffered in a file system cache somewhere.

Most shared file systems can be configured to work in this mode and indeed MUST be configured in this mode to be safe for use with WebSphere in this model.

May have been obvious, but worth pointing out.
