I couldn't find any hints on how floating and fixed licenses should behave on AIX 4.3

The problem we got here is this:
there are 85 fixed user licenses.
We ran out of them.
I increased the number fixed licenses to 150.
Since it requires a reboot I added 50 floating licenses with smit. (can't reboot right now)

makes no difference whatsoever.

why not?
monitord is running, smit shows the 50 float licenses.

Also how is AIX licensed? I am quite baffled by the fact that I can increase the number of licenses arbitrarily.

pointers to online docs would also be welcome.
