Problems porting an application from HPUx 11 to HPUx 11.11

Hi Everybody,

I am pretty new to the HPUx topic and got the job to port a CORBA application from HPUx 11 to HPUx 11.11.

I recompiled and installed the whole thing on the new machine, it compiled without errors, but when I try to run the application it core dumps.

The stack trace delivers the following:
#0 0x77f34b7c in _sigfillset+0x5bc () from /usr/lib/libc.2
#1 0x77f3297c in _sscanf+0x68c () from /usr/lib/libc.2
#2 0x77f3801c in malloc+0x18c () from /usr/lib/libc.2
#3 0x77d83a08 in operator new []+0x40 () from /usr/lib/libCsup.2
#4 0x77bd8ae8 in ObjectReferenceImpl::ior_extract_MT_UNSAFE+0x68 ()
from /cluster/oowma/appl/Orbix_3.3/lib/liborbixmt.3.3.aCC.1
#5 0x77bd8a34 in ObjectReferenceImpl::ior_extract+0x5c ()
from /cluster/oowma/appl/Orbix_3.3/lib/liborbixmt.3.3.aCC.1
...

As you surely have seen we use Orbix for the CORBA stuff.

Now, when I do a "set heap bounds on" the application runs without any warning / error...

When I do a "set heap free on" I get a few notifications about maybe corrupted footers.

Now, as you surely already noticed I am not very experienced in the C++ - Unix story...

So, what can I read from the above to messages? Is there a way to find out, where the heap bounds are violated, or who violated them?

I also tried to increase the MAX_DSIZE Kernelparameter with no effect.

Has there been any additional restriction about the stricness of allocating and freeing memory between HPUx 11 and 11.11?

I really hope someone can help me in this topic, it's almost driving me insane...

best regards

Compare kernel params on 11.00 and 11.11
also you can check Kernel parms with Glans.
Did you install all needed library ?

send your error !

Hi,

the server terminates with a SIGSEGV.

The client naturally says "no connection to server".

Where can I find Kernelparams in glance? I know, you can monitor and change them in SAM (but only with admin-rights), but in glance?

HI
Glans Plus is HP software.
you can download and install free 30 day version from software.hp.com

Just start Glans and review menus
#glance
for shell
#gpm
for X env
Find system menu for kernel parms

Re: Problems porting an application from HPUx 11 to HPUx 11.11

Hi

sigsegv is indeed memory

kmtune -l on the machine to see all the variables

file applicationexecutable to see if a 32 or 64 bit application
ELF-64 executable object file - PA-RISC 2.0 (LP64) is 64 bit


check /var/adm/syslog/syslog.log for messages

check swapinfo -at for enough swap

see
ftp://eh:spear9@hprc.external.hp.com/memory.htm

tells you how to use glance and other soft to check memory usage

Hi again,

thanks a lot, I will look at the ftp-document you mentioned and see, if I find out more...

Re: Problems porting an application from HPUx 11 to HPUx 11.11

Hm, that document looks real interesting. I think I will ask our operations team to adjust some parameters...

But there two other questions came up:

1) I found out my app is compiled as a 64 Bit app. Could it be any problem that it has been linked against 32-Bit libraries?

2) which bounds exactly does set heap-check keep an eye on? I am wondering because if it is enabled the application runs properly if it is not enabled it core dumps...

Re: Problems porting an application from HPUx 11 to HPUx 11.11

Hi

If it uns with heap check then 1 is no problem

HeapCheck, which can detect problems that corrupt the system memory pool, such as writing off the end of an array or using a "freed" pointer.

Thus you have a memory leak

Check for Java version and latest patche son machine via

www.hp.com/go/java and the itrc

Re: Problems porting an application from HPUx 11 to HPUx 11.11

Is java also important if the application is in C++?
