Modifying shared memory kernel parameters for SMA on AIX
On AIX systems, the shared memory kernel parameters do not need to be modified for use with Shared Memory Access (SMA). The upper limits are defined for the AIX IPC mechanisms, which are not configurable. The shared memory limits are allocated and deallocated dynamically as needed, so that the memory requirements always depend on the current system usage.
Important Do not set the page space allocation policy to early page space allocation. Instead, use the deferred (default) or late space allocation policy.
