If you rely on journaling for hardware failures, put your journal receivers into a different ASP. If you want to protect your data from loosing your computer room, have two rooms in two different building fiber attached and mirror from one cabinet in room A to the remote cabinet in room B or to a completely different machine in a completely different building. If you want to protect from application failure, journaling is great. Journaling also works great for catastrophic disk/ctl failure if you use two ASP on two controllers on two busses. Journaling does have its place but not for High Availability! Christopher K.

If you expect to depend on Journalling as a poor-man's solution, there's a good chance that you are fooling yourself. You can set up procedures so that you can be fairly confident in recovering from your last SAVLIB (or SAVwhatever), but the confidence level in applying journal changes goes down quickly. Thanks for the info, Al. It's not what I wanted to hear, but I appreciate your frankness. Phil
