Hi all,

we have Hobbit 4.2.0 up and running (very well!) and we have BBWin client installed on our Windows servers. We started to install hobbit client on our AIX server (AIX 5.2) using this pre-built package _http://rpm.razorsedge.org/aix-5.2/RE/ppc/hobbit-client-4.2.0-4.aix5.2.re.ppc..._ and it works fine.

But I noticed different memory reporting between AIX topas command and Hobbit web page, as follows

=== Topas output ===

Real,MB 8191 % Comp 49.3 % Noncomp 51.6 % Client 51.8

PAGING SPACE Size,MB 7680 % Used 20.5 % Free 79.4

=== Hobbit web output ===

Memory Used Total Percentage green Physical 8189M 8192M 99% green Swap 1612M 7680M 20%

While Total memory (8192MB) and Swap (7680MB, 20%) values are correct, reported Physical memory value is incorrect. Right value is % Comp 49.3 NOT 99%.

Is there anything I can change to have the right value?

Hi

AFAIK, AIX uses (by default) a lot of memory for file caching, so you end up using ~100% of your physical memory.

Try running this :

/usr/samples/kernel/vmo -a | grep perm%

    maxperm% = 40
    minperm% = 20

This means that 40% of your memory can (and often, is) be used for file caching.

vmo is available under AIX 5.2/5.3, you can use vmtune under AIX 5.1
