Hello,
I try locked shared memory with shmctl.
I get :

ipcs

------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x00000000 131072 root 644 110592 6 dest
0x00000000 163841 root 777 196608 2 dest
0x00000000 262146 root 644 110592 2 dest
0xd679dce8 360451 oracle 640 38506496 6 locked

Segments 'oracle' is locked (I guess)

cat /proc/meminfo
total: used: free: shared: buffers: cached:

MemShared is 0kB. Why ?
Is shared memory really locked ?
