Storing transaction and compensation logs in a relational database for high availability

This is something about which I've been reading recently.

I was semi-aware that WebSphere Application Server 8.5.5 offers the option to store transaction and compensation logs in a relational database rather than as operating system files, providing high availability (HA) support without having to use a shared file system.

However, a colleague also pointed out that this functionality has been retrofitted into WAS 8.0 via Fixpack 7 ( 8.0.0.7 ), as per the Information Center here: -

which is nice to know.
