Hey, did anyone re-worked IPC naming design recently?
Several years ago it was implemented simply as a base number + an integer
number preassigned to the particular IPC object at compile time.
Since a few preassigned numbers are reserved for every database instance
increasing the max number of databases to 10000 inflates the range of
preassigned numbers greatly.
This doesn't affect resource consumption in any way however the probability
of naming conflict with IPC objects that don't belong to Sedna is increased.
You known SYS V uses integer "keys" to identify objects.
Normally such a key is obtained from ftok instead of using some arbitrary
number.
There could be other issues as well since no one ever tested or even
considered the number of databases being increased so high.
