Re: Immediate PTF -- What's the point?

Glad to see that Vern only found a few with this wording.

While a ptf may be applied immediately often there will be some action 
required.  Sometimes the action is drastic enough that you might as well 
IPL.  Sample actions may include:
- Ending all users on all twinaxial ports.
- Bringing the system down into a restricted state.
- Ending all TCP/IP.
There may be good reasons to do this.  Much as often you have to kick all 
users out of an application when you update a screen program.

Technically, it makes IBM look good if they can reduce the number of PTF's 
that require an IPL to apply.  However, with the gyrations you have to go 
through to make some of these ptf's active it makes this number game about 
as meaningful as (editted for sensitivity).
