Its been a long time since my historian was configured but I have managed to go 
past the licensed maximum by deleting points
I am at Unix 6.5.3 and aim 3.2.3 but have been past maximum for a while
histmgr reports 1873 configured, 127 available but 5000 maximum
histcfg reports 1873 configured 2000 licensed 127 available, but I am up to 
line 2242 for tag entries

the only clue is the 5000 maximum reported to histmgr but I don't know how it 
got there, a concern would be that aim 3.2.4 breaks it for me

Even after a force delete the license software wont release the point back in 
so that another point can be added. This has been added as a car but no real 
resolution as far as I am aware. You can verify this when deleting a point by 
first looking at the value in the histmgr instance tab, Real Time Points 
section and configured points value. When the point gets deleted this value 
should increase by the number of points deleted/force deleted. Our system 
reached the limit due to points being added and some were deleted so additional 
points could be added, however this didn't decrease and we were forced to 
increase our license to add the additional points even though our total count 
of active points was less than the original licensed amount of active points. :(
This meant $$$$ spent due to a bug or lose historical data and start the 
historian over.

List,

You can FORCE_DELETE your incorrect or deleted AIM points.

I use a small script to do this.
Basically you do a histcsave, use the "histname"_del.inp file to filter o=
n deleted point and do a force delete for these point with histcbatch (yo=
u will see that the used index nr is gone but you will be able to put new=
 points in. without deleting your complete database and rebuild it and lo=
ose al you histdata.
 
Syntax for force_deleted is: 

1 DELETE POINT C:B.P NAME FORCE_DELETE
