I have 473 java licenses available. I started using license reservation for a subset of my total profiles in my production environment (the thought was to ensure my most critical deployments had sufficient monitoring). 7 of 12 profiles have specific reservations (Min and Max). The reservation screen shows 19 licenses available. Do I need to include all profiles in the reservations screen (it seems like the left out profiles don't get any licenses even if they are available). The documentation doesn't go in to much detail.
Yes, I think you would need to include the other profiles in this case. Since 7 of the 12 profiles have reservations, you only have a small subset of licenses left (sounds like its 19?) for the remaining 5 profiles. Even if more than 19 were available at any point, the extra would not be allocated towards the 5 profiles since they are 'reserved' for the 7 profiles.
Hope that makes sense.
