ADB issue on 11iv2

Geoff Wild — Thu, 04 May 2006 09:03:36 GMT

Comparing 2 RP4440 HP-UX 11.23 systems.Both have:

HPUX11i-OE-Ent B.11.23.0505 HP-UX Enterprise Operating Environment Component

I have a script called hpmem (attached).

On one system, works perfect...

On other, I get an adb error - but it still works:

# hpmem

Something up with these lines?

hexval=$(echo "phys_mem_pages/A" | adb $kernel /dev/kmem | tail +2 | awk '{print $2}')
REAL_MEM=$(echo ${hexval}=D | adb)
mb=$(expr ${REAL_MEM} / 256)

From command line:

# echo "phys_mem_pages/A" | adb /stand/current/vmunix /dev/kmem|tail +2 |awk '{print $2}'
0x17fe00

no error - so that seems fine...

Try full:

hexval=$(echo "phys_mem_pages/A" | adb /stand/current/vmunix /dev/kmem|tail +2 |awk '{print $2}')

That's okay...

REAL_MEM=$(echo ${hexval}=D | adb)
adb: warning: No memory file specified ...
adb: warning: Using 'core'.
adb: warning: Object file not SOM ...
adb: warning: Shared library symbols could not be read.

Aha - what gives?

Is it really a good idea to be using adb to try to pull those things from the kernel?

IIRC there is kctune to get the value of those tunables. Not sure about some of the other stuff if there is a way to grab them via a script, but it might be good to investigate to avoid using adb that way.

Can kctune get cpu and memory info?

Not that I'm aware. At least some of that comes out of machinfo though.

Geoff Wild — Fri, 05 May 2006 15:46:34 GMT

Rick, but isn't /usr/contrib/bin/machinfo for IA64 only?

I wasn't under that impression, but then I also don't have a PA-RISC system running 11.23 to try it on. Some of what you want may also be available via getconf

Hi Geoff:

According to the manpages, 'machinfo' is confined to Itanium processors only:

Nothing wrong with adb -- it has definitely undergone some changes to support IA64 but as has always been true, HP-UX symbols are subject to change without notice. It appears that adb's ability to convert a number to another base requires some changes (or may require use of bc instead). The warnings indicate that it expects a memory and object file.

I wrote a similar script to gather info from HP-UX versions 7.xx, 8.xx, 9.xx and 10.xx and there were kernel changes in every revision. Sorry, I don't have a list of the new or changed symbols.

Here's a link for 11v2 Release Notes. adb is covered on page 274:

Well, that's annoying - indeed the manpage does say IPF only - in something right up at the top in the header I often ignore :( and nothing in the text itself.

Hi Geoff,

"machinfo" added to HP-UX from 11.2x onwards. But, when you install 11.23 in a PA box, you won't get this nefty little utility.

Not sure will it be available from 11.31 onwards to PA.. ??

Shalo Geoff,

Interesting. Another little nudge form HP to go Itanium. You get the feature on IPF but not PA-RISC.

If the "rumor" is true and 11.31 is the last PA-RISC release this brings forth important decisions for the admins that make recommendations and the management that listens. PA-RISC is even today not being provided the same level of support as Itanium.

Interesting indeed, as last Thursday I tried to do my first 11i v2 install on a rx2600 box (I admin a few now) and the box just broke and won't even except its 11i v1.6 Ignite backup.

In the end it was just the core in the same dir whrn I ran the script...
