I think I have to disagree.  I can't see where there is any evidence that 
altering the LINKLIST while things are running would not "work".  If that were 
the case, I think there would be a lot of angry people opening problems with 
IBM support, and I would be one of the first on that list of people.

Not using the features is not an option, that's why we asked for them in the 
first place.  I know that IBM doesn't always provide what we ask for, but in 
this case it was done and it has never been unsuccessful for me.  I install and 
upgrade new systems for clients many times per year and I have yet to have this 
process fail or to experience a problem with this method.

I "could" just be lucky, but with the frequency that I use these commands and 
the number of systems I use them on, I would think that I would have 
experienced a problem by now.:)
