Oh shi... For those who don't follow the list, here's something we've so far overlooked in our DR planning.

In the server, yes, but it's not needed for the apps. There are some concerns, however, if one of the universes collapses while holding the file locks, but we've been unable and unwilling to test this in the lab. After all, one does not collapse a universe without a good business reason, as getting the darned thing restarted tends to disrupts the containment field that hold the singularity. The result is debris everywhere; a real mess. The building maintenence people get upset. Not Good. [As an aside, planning for the collapse of the universe is a customer responsibility. IBM assumes no responsibility in this area. Please ensure your DR plans include this scenario.] Alan
