Parameter
ipc/shm_psize_<(><<)>xx<(>><)>

Short text
Size of shared memory segmentsYou can specify the pool sizes for shared memory pools with thisparameter.
Essentially, you can make three different settings:
ipc/shm_psize_<(><<)>xx<(>><)>=0Pool <(><<)>xx<(>><)> is not to be created
ipc/shm_psize_<(><<)>xx<(>><)>=n, where n<(>><)>0Pool <(><<)>xx<(>><)> is to be created with a size of n bytes
ipc/shm_psize_<(><<)>xx<(>><)>=-<(><<)>yy<(>><)> where <(><<)>yy<(>><)>
is the number of anotherpoolPool <(><<)>xx<(>><)> is to be created in pool <(><<)>yy<(>><)>
Example
ipc/shm_psize_06=-10 Pool 6 is created in pool 10
ipc/shm_psize_10=23000000 Pool 10 is to be 23 MB in size
ipc/shm_psize_14=0 Pool 14 is not to be created(size 0)
