An HPUX would say how much memory at boot time:
After you would have to use other tools like glance/gpm stm etc...
In simple language, what you are seeing in top is the reflect of how HPUX works (memory management...) For HPUX memory is "virtual" and so your device swap count as memory...
HPUX till 11.23 (after I have no boxes nor knowledge...) the size of your usable (addressable) memory is the size of your swap
Depending on the kernel parameter swapmem_on (set to 0/1) it will extend the swap size by using some of your RAM... and so extend its "memory".
As you can see, depending how you configured your kernel and swap size you may face different issues: Not enough swap although plenty RAM, and box saying run out of mem resource or boy loading far more than it can afford and swapping like mad...
I will present you 2 cases:
box1 D230 HPUX11 with 1 GB RAM:
You could guess by looking at the above outputs that this box swapmem_on is set to 0:
swapmem_on 0 - - -
(TRUE!) And you know this box could not exceed 1 GB memory usage...
If it had swapmem_on on, it would have maybe an extra 200MB of addressable memory...
Box2 : K360 HPUX11...
2GB RAM - 5GB swap
5GB swap matches the total device swap so?
swapmem turned off... but 5 GB of memory would be seen...
This allowed me to install 6 oracle (of different versions...)instance plus 1 sybase and more than 600 concurent users and the lot was slow perhaps but was from the beginning and everybody was happy once used to its speed (180Mhz bi-proc..) The most amasing... Never did you have a cursor freeze for a moment even short...
Box3 L2000 HPUX11.11
you comment...
How much can be loaded in memory?
And so?
Now tricky one
Box4 L2000 (RP5450) HPUX11.11
All the best

As the artefacts are non repetetive (rewinding and watching again does not show artefacts), I can exclude a corrupted video source.... (23 Replies)

is there any idea bout that ?

Hi all,
Unix has the TOP and SAR command to monitor machine's performance. Can it be used in a script to alert if the cpu utilization is more than 80 or memory used is more than 90.
Is SAR preferable than TOP?
Please advise. (3 Replies)
