IBM i : Share Memory Control (QSHRMEMCTL) - '1'

Information

The Share Memory Control (QSHRMEMCTL) system value defines which users are allowed to use shared
memory or mapped memory that has write capability.

Solution

Set QSHRMEMCTL to 1, so that users can use shared memory or mapped memory that has write capability.

This value means that users can use shared-memory APIs (for example, shmat()
- Shared Memory Attach API), and can use mapped memory objects that have
write capability (for example, mmap() - Memory Map a File API provides this
function).
