purify on Itanium

Nyck_1 — Tue, 05 Aug 2008 05:40:11 GMT

I have been told by IBM that purify is available to Itanium but its not tested/supported on dual core. Has anyone out there used purify on a dual core itanium and if so does it work ok?

Thats my original thread from many moons ago:-)

I can go ahead and install it but I want to be sure that it will not crash my main development server once its being used!

Shalom,

If it works on Itanium at all, dual core will not be an issue. IBM is being a little anal here.

That came up before and that was our conclusion. It may make more sense if hyperthreading was involved.

Hi,

the Interim Fix 7.0.0.0-010 has support for HP on Itanium.

ftp://ftp.software.ibm.com/software/rational/private/pplusu-LJfG9yhjSvzR/PurifyPlus-7.0.0.0-010-release-notes.html

I don't know, if this a public available URL, however.

That is the one I have just installed on our itanium server and the install went fine. So its now handed over to the development guys to see if it works!

Well I installed purify yesterday and the developers gave it a whirl and it core dumped with the following:-

Missing BranchOut in Function at 0x4000000000E9A620
Address : 40000000012C1FC0
Missing BranchOut in Function at 0x4000000000E9A620

Does this ring any bells?

Hi,

did they use a compiler, which is supported by Purify-7.0.0.0-10 - use the Release Notes.

And: raise a call at Rational!

I'm looking to see which compiler they are using as the release notes mention that it has to be a certain level. Also purify is not actually supported on dual core itanium servers, so not too sure if i will get much help there.

I would ignore this part, you haven't even gotten to running it yet.

I have a contact at IBM who is going to help me out with this purify issue. I will let you know the solution.

I personally now believe that its probably the version of compiler we have on that server, its quite an old one.

Hi, I also try to use Purify on Dual Core Itanium, I installed it and it is successful for Purify Examples.
But when I try to compile my project as below, the system is hangup, I have to shutdown my HP server by power button, does anyone give me some advise? Here is my command:

purify cc -g -Ae -Y +Olit=none +wlint +DSitanium -Dhpux -o myproj.o myproj.c

purify cc myproj.o -L/opt/oracle/product/10.2.0/db/lib32 -lclntsh -o myproj

Instrumenting: myproj
libclntsh.so.10.1........................

Hi, did you get any answer?

>I try to compile my project as below, the system is hangup

I've had purify run over 24 hours before I killed it. Did you try kill then kill -9?

I assume you know that you can use +check= to check array bounds and heap corruption?

Re: purify on Itanium

Nyck_1 — Tue, 12 Aug 2008 04:54:47 GMT

I'm still awaiting a response from IBM, they are doing this as a favour so it might take a little longer. As soon as I get an answer I will let you know!

You are lucky!
I can't login even as root, I have to reboot it.

>I assume you know that you can use +check= >to check array bounds and heap corruption?
What do you mean?
The hangup was not happened when I run myapp, it was happened when I built myapp suing purify.

Now I got a method by build time options as below:
-selective -exclude-libs=libclntsh.so.10.1

By the way, I am working on

HP-UX 11i v3(11.32)
B3910B.A.06.15 compiler
B.12.43 linker ld

You need to monitor it with top to see what's going wrong. Are you out of swapspace?

>What do you mean?

Instead of using purify, you can compile with +check=.

>A.06.15

You can patch up to A.06.17, PHSS_37950.

I gor the reason, as no more memory.

>Instead of using purify, you can compile >with +check=.
I am not sure about this option, I will check it, you mean they have similar function?

>You can patch up to A.06.17, PHSS_37950.
Thanks a lot, I will try.

By the way, I run my app, I got a core dump as below:
in x_pure_change_sp+0 /purify.hpia.7.0.0-010/lib32/librtlib.so
....
in EM_mark_BOS+0x50 /usr/lib/hpux32/dld.so

Do you have any suggestion about this core dump?
