shmat - shared memory core dump differences (NcWn353)
Shared memory segments created with the shmat system call are
included in process core dumps by default on Tru64 UNIX but not on
On Tru64 UNIX, the shm_enable_core_dump system attribute disables
(0) or enables (1) the dumping of shared memory segments. The default value is 1.
On HP-UX, the core_addshmem_read and core_addshmem_write kernel tunables disable (0) or enable (1) the dumping of shared memory segments. Their default value is 0.
These mechanisms only affect shared memory segments created with
shmat and do not affect memory regions created with mmap.
To include shared memory segments in process core dumps on HP-UX,
set the core_addshmem_read and/or core_addshmem_write kernel tunables to 1.
