Nick,
z9BC to z10BC : Last time I looked at an upgrade, processor speed will be
better but, check what was ordered. Engine speeds can depend on which model of
z10BC. As others(Roger,Mark,Alan,...) have already said, NO need to change the
directory entries first shot out of the barn, except for your most precious
guest(s) and those currently running constrained (90-100%).
If you do change the directory, z/Linux will have no problem using the
additional processor, z/VM will dispatch as usual.

Subject: 2 to 3 IFLs
Hello All,
We are upgrading our z9BC to a z10BC and increasing the IFLs from two to
three. I am planning on modifying the Linux guest definitions to utilize the
third IFL. Are there any performance issues or problems adding a third IFL? I
can't imagine this would do anything but help, I'm just checking.
We are running z/VM 5.4 in support of Linux guests.
TIA!
