oradiag has joined #systemtap
<oradiag> hi all
<oradiag> I have some trouble installing systemtap on OL7.2
<oradiag> can anyone help?
<fche> hi oradiag
<fche> you figured irc out :)
<fche> ok so what have you tried, what are you seeing
<fche> see also [man error::reporting]
tromey has quit [Quit: ERC (IRC client for Emacs 25.0.90.1)]
<fche> OL7.2 is a rhel7.2 clone AIUI, so it should work just fine with the RHELish kernel
<oradiag> let me give you some background
<fche> the UEK one - if that's the one with the dtrace port in it, dunno, maybe oracle has hobbled the relevant parts of that kernel
<oradiag> previously, I've successfully installed systemtap on OL7 a few times
<oradiag> on virtual machines
<oradiag> now I finally got access to a physical Linux machine
<fche> (stap doesn't care either way)
<oradiag> however, the OS was not installed by me
<oradiag> so there may be some conflicts
<oradiag> anyhow, I tried the following:
<oradiag> yum install systemtap systemtap-runtime
mjw has quit [Quit: Leaving]
<oradiag> then I installed kernel-debuginfo
<fche> (you don't need kernel-debuginfo for userspace probing)
<oradiag> kernel-debuginfo-common
<oradiag> ok, good to know
<fche> see [man stapprobes] for more on that
<fche> ok so cutting to the chase, what script are you trying to run, with what results ?
scox has quit [Ping timeout: 250 seconds]
<oradiag> actually I tried to reinstall some packages
<oradiag> and now it's not running at all
<oradiag> I'm trying to run a script I downloaded from Luca Canali's blog
<oradiag> doing some probes of oracle function calls
<oradiag> and now it's failing to start
<oradiag> give me a min to email the error message across
<fche> can you paste the script / invocation / error message somewhere like pastebin or fpaste.org ?
<oradiag> as I'm connected to irc from a different machine
<oradiag> I guess I could
<oradiag> just not familiar with those
<fche> (web-based clipboard)
<oradiag> and not sure if I can open them at work
Test has joined #systemtap
<oradiag> yes, the names are pretty self-explanatory :)
<oradiag> let me try
<fche> failing that, yeah email to systemtap@sourceware.org
<fche> but in general things should work.
Test is now known as Guest17470
<fche> you will need the appropriate kernel-devel regardless
<fche> (consider running # stap-prep to check on things like that)
<oradiag> email sent
<fche> see also # stap-report
<oradiag> the email came back
Guest17470 has quit [Client Quit]
<fche> basically please scan over man error::reporting and SEE ALSO's
<fche> plain text only on that server
<fche> attachments give it spam worries
<oradiag> it was plain text
<oradiag> lib/modules/3.8.13-98.7.1.el7uek.x86_64/build/.config: No such file or directory
<oradiag> I had to omit the leading slash
<oradiag> actually, that's not quite accurate
<oradiag> the actual error message was: /lib/modules/3.8.13-98.7.1.el7uek.x86_64/build/.config
<oradiag> let me try stap-prep
<oradiag> looks like stap-prep is for Fedora?
<oradiag> it's complaining about missing packages -- but those packages are actually installed... and it's trying to download stuff from wrong repos and keeps failing...
ajakop has quit [Quit: Leaving]
drsmith has left #systemtap [#systemtap]
<fche> hi
<fche> back now, sorry, had to gut a chicken :)
<fche> ok so you're running a uek kernel, but are lacking the corresponding kernel-devel headers
<fche> (I don't / can't run UEK.)
<oradiag> yeah I've seen that link
<oradiag> doesn't look quite the same though
<fche> ie try #yum install kernel-uek-devel
<oradiag> it's alredy installed
<fche> the same version though?
<oradiag> although it's slightly more recent version
<fche> it has to match
<oradiag> than the rest
<oradiag> not exactly
<fche> righto. so that's step 1 - getting your kernel-uek and kernel-uek-devel into beautiful synchrony
<oradiag> the thing is
<oradiag> when I uninstall it
<oradiag> and try yum install kernel-uek-devel again
<oradiag> it's trying to install the same version as before
<fche> you may need to append the version code matching your kernel
<oradiag> i.e. more recent than everything else
<oradiag> tried that, too
<fche> i.e., kernel-uek-devel-3.8.13-98.7.1.el7uek.x86_64
<oradiag> although maybe not correctly
mbenitez has quit [Quit: Leaving]
<oradiag> just tried again
<oradiag> same as before
<oradiag> no package kernel-uek-devel-3.8.13-98.7.1.el7uek.x86_64 available
<fche> may have to look around oracle's software repositories for taht
<fche> or upgrade your kernel proper
<fche> or ... contact oracle support?
<oradiag> ok thanks
<fche> so anyway stap uprobes won't work (nor will any other out-of-tree kernel module stuff like vmware) until you have matching kernel & -devel
<oradiag> I see
<oradiag> I wonder why that particular version is not available
<oradiag> I guess I'll try to upgrade the kernel
<oradiag> maybe straight to version 4 if I have to do it anyway
<fche> your choice; I would suggest the smallest steps necessary to find all the dependencies
<oradiag> okay, thanks for your help!
<fche> np, hope the next error message you get is different! :)
<oradiag> :)
