The NCP load module is not a problem, as you should already be
licensed for NCP and SSP on your z/OS system -- after all, it's the
3745s that you already have that you want to replace with CCL, right?
Tony is correct in that CCL is a licensed product; as we all know
getting a license to run IBM mainframe code on Hercules is, well,
difficult. ;)
For the curious, I know that an NCP on CCL (under SLES 9 SP1) and
VTAM in z/OS v1r4, both running under z/VM on a FLEX/ES machine, will
chat quite happily through an Ethernet switch or crossover cable.
Running the CCL part under Hercules would in theory not be a problem
-- but it would be a good test of the accuracy of Hercules' LCS
emulation :)
Bear in mind that depending on how much traffic your 3745s handle,
CCL can be hungry for resource -- I've heard that the amount of SNI
traffic that a maxed-out 3745-61A could handle will consume an entire
zSeries IFL with CCL...
Sellers of the FLEX/ES boxes might get some business; for some shops
with only lightly loaded small 3745s and no grander plans for Linux
on zSeries, buying a FLEX/ES system to run CCL on might be a better
financial proposition than buying an IFL (and storage, and maybe
disk, and probably more OSAs...).
