Based on your operating system and
architecture, the formulae are provided in
the following list:
v HP-UX 32-bit:
If memory allocated to the container node
is greater than or equal to 3068 MB, it
allocates 3068 MB. Else, if the memory
allocated to container node is lesser than
or equal to 512 MB, it allocates the
memory assigned to the container node.
v HP-UX 64-bit:
if (MEMORY_CONTAINER >= 3068, 3068,
if (MEMORY_CONTAINER <= 512, 512,
MEMORY_CONTAINER))
v IBM AIX 32-bit:
if (MEMORY_CONTAINER >= 3068,
MEMORY_CONTAINER, if
(MEMORY_CONTAINER <= 512, 512,
MEMORY_CONTAINER))
v IBM AIX 64-bit:
if (MEMORY_CONTAINER >= 3328,
MEMORY_CONTAINER, if
(MEMORY_CONTAINER <= 512, 512,
MEMORY_CONTAINER))
v Sun Solaris 32-bit:
if (MEMORY_CONTAINER >= 3900, 3900,
if (MEMORY_CONTAINER <= 512, 512,
MEMORY_CONTAINER))
v Sun Solaris 64-bit:
if (MEMORY_CONTAINER >= 1536,
