Thanks, we have not done any upgrades to the Mainframe in over two years. 
My memory cells were very fuzzy on this. I had changed the memory but had 
not IPL'd. We just did that now and all is looking good.
The management that was here has left. The decision has been made that the 
cpu will remain here for at least 3 more years and the current management 
agrees living on unsupported software for that long is not a good idea.
Now I get to take off my new Unix hat and put the MVS hat back on.

And you don't even absolutely __need__ to do a deactivate and activate,
just change to 64 bit mode in the LOAD member. If your LPAR defination
has XSTOR in 64 bit mode, you'll just get a whining message at IPL time
and the XSTOR is ignored.
