Trace System Call

cmo-itri — Mon, 11 May 2009 07:07:37 GMT

I've read some articles. I can use the trace-1.6 to trace system call on HPUX 10.2. My question is: where I can download the trace-1.6? many Thanks.

That tries to reach so far back into the bot-rotted areas of my dimm memory I can barely remember that there was any system call tracing on 10.20... But what little recollection remains suggests it was spotty at best.

If at all possible, you would be far better-off with tusc on an 11.X release.

Still, if you must tilt after the windmill of 10.20 system call tracing, you might ask in netnews in the comp.sys.hp.hpux newsgroup and/or check its FAQ.

If simple counts/rates of system calls would suffice with your 10.20 situation, you might be able to use glance - if it is installed that is.

I find the trace-1.6 on http://forums11.itrc.hp.com/service/forums/questionanswer.do?admit=109447626+1242097381969+28353475&threadId=1233991, but the link about trace-1.6 was broken. Because I have a program that's will core dump randomly, so I need to catch the signal-SIGSEGV. Tracing the system call maybe can help me.

Not that I have the details handy as to which debuggers were around in 10.20 nor how they would be used, but have you considered running the application under a debugger?
