LINT and the ipcs command seem to disagree on some points, like the
meaning of shmall (bytes vs. pages). In all examples, I've put the
quote from LINT followed by the excerpted output from ipcs -M or -S.
options SHMALL=1025 # max amount of shared memory (bytes)
vs.
shmall: 1024 (max amount of shared memory in pages)
Also, some values are very different:
options SHMMNI=33 # max number of shared memory identifiers
vs.
shmmni: 96 (max number of shared memory identifiers)
whereas many others are just off by one:
options SEMMNU=31 # number of undo structures in the system
vs.
semmnu: 30 (# of undo structures in system)
What I really want to know is, what do all these LINT variables mean? I
have a user who needs more semaphores and shm segments configured, and I
want to make sure I tune the right ones. Apparent candidates are
SHMMNI, SHMSEG, SEMMNI, SEMMNS, and SEMMSL.
