Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

the OS_MEM_FREE Column from Sysmaster:SysMachineInfo is Misleading on AIX

Take for example the following query:

select os_mem_free from sysmaster:sysmachineinfo;

This returns the amount of free memory on the OS in bytes. We
appear to get this information from the same function that
gathers that info for OAT (via the SMI query) and onstat -g osi.

The system call being used appears to be grabbing what is seen
in svmon -G's "free" column. (see below) While this does tend
to be showing a true value for free memory on the system, it is
not an accurate representation of the real available free
memory. That's because this free value incorporates a lot of
memory reserved/cached by the OS. Yet this memory can be
redistributed to new shared memory segments and process heap
memory if needed.

A more accurate value for free memory on the system (i.e. memory
that could be available if needed) would be the (memory->size) -
(memory->virtual). Or (memory->size) - (in use->work).

The wording for this description was supplied by IBM employee Brian Oligschlaeger [oligschl@us.ibm.com].
