Core file management with HP-UX on Itanium (points!)

Christian Deutsch_1 — Mon, 21 Apr 2008 12:34:37 GMT

Hi folks,

This thread has been closed: http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=898593&admit=109447626+1208434092190+28353475

The command works for HP-UX 11.11 but on HP-UX 11.23 on Itanium I get:

echo " core_addpid/W1" | adb -w /stand/vmunix /dev/kmem

core_addpid:
adb: warning: Unrecognized format character - 'W'.

Does this matter? If so, what command must I use on HP-UX 11.23 on Itanium?

Truly helpful answers will be generously rewarded with points!

Thanks, Christian

You just need to add "-o":
echo "core_addpid/W1" | adb -o -w /stand/vmunix /dev/kmem

And on 11.31, just use coreadm(1M).

Hi Christian:

First, that should be a lowercase 'w' not an uppercase one.

In 11.23 you have 'coreadm' to manage core files:

For more info about core files you might want to look at the wdb documentation:

coreadm is only available in 11.31, isn't it?

Hi Christian

use "w" and after a space then 1

# echo "core_addpid/w 1" | adb -o -w /stand/vmunix /dev/kmem

Hi folks,

Ahsan's command worked, James' command did not.

I have no indication so far that coreadm is available on HP-UX 11.23. If someone thinks it is, please tell me where to find it?

Thanks for all your responses, Christian

>I have no indication so far that coreadm is available on HP-UX 11.23.

You should have given my reply precedence. :-)
If you looked at JRF's man page entry, it clearly says 11.31.

I'm pretty sure it is "W" and not "w", I'll check the source later.

coreadm is for HP-UX 11iv3 only.
I am unaware of any current plans to backport it to 11.23 at the moment

Hi (again):

My apologies, I meant to say that in *11.31* you have 'coreadm'. I erroneously muddied the water when I said 11.23 when I meant 11.31. Dennis caught that. I guess He's used to me :-)

Regards!

>JRF: Dennis caught that. I guess he's used to me :-)

I did but I was going to let it slide since the man page said 11.31.

>ME: I'm pretty sure it is "W" and not "w", I'll check the source later.

Yes, the proper adb format is "W" and not "w". It is a 4 byte int.

Dear Dennis,

Thanks for the link for wdb that can be very helpful!

As a matter of fact, both of these commands work:

echo "core_addpid/w 1" | adb -o -w /stand/vmunix /dev/kmem
echo "core_addpid/W 1" | adb -o -w /stand/vmunix /dev/kmem

This one does not work:

echo "core_addpid/W1" | adb -o -w /stand/vmunix /dev/kmem

Any comments?

Christian

>As a matter of fact, both of these commands work:

As I mentioned, don't even think of using "/w", it doesn't clear all 32 bits.

>This one does not work: echo "core_addpid/W1"

Naturally, it needs a space between the format and the value. (I was only looking at the adb option side and I assumed that the original thread had the LHS correct.)

ok then to make things a little bit cleaner I will use these:

for HP-UX 11.11:

echo "core_addpid/W 1" | adb -w /stand/vmunix /dev/kmem

for HP-UX 11.23:

echo "core_addpid/W 1" | adb -o -w /stand/vmunix /dev/kmem

Thanks for all your help, Christian
