extraction of a cpio file

[Grayh]

Hi All
When I was trying to extrace the below file on 11.23 hppux version.. I get the following error....
does that mean i have stopped it in the middle of extracting... it was almost 35 minutes that I have started to run this file....

# cpio -idcmv 10gr2_aix5l64_database.cpio
^Z[2] + Stopped (SIGTSTP) cpio -idcmv 10gr2_aix5l64_database.cpio

Is there a limitation for cpio on hpux also.. if so .. Is there any other way i can extract this file...

Hi:

The 'SIGTSTP' stands for "terminal stop". You probably typed CTL_S to stop the process. Try typing a CTL_Q to restart it.

"^Z[2] + Stopped (SIGTSTP) cpio -idcmv 10gr2_aix5l64_database.cpio"

thats not an *error* message, its *warning* you that *you* stopped the process by hitting a Ctlr-Z.... or somebody issued a "SIGSTP" (via kill ?) to that PID.

in posix / ksh it can be resumed with the "fg" command, if it was stopped from the keyboard, as in "fg %2", or
by sending SIGCONT (or 26) from a kill.....

I doubt that you need another method, if you let the one you tried work.

Thanks everyone... So I have left it as it is... it running since the last 20 minutes... Not really sure when it will stop execution

I have copied that cpio file from the below location

http://www.oracle.com/technology/software/products/database/oracle10g/htdocs/10201aixsoft.html

and the size of the file is (1,268,576,110 bytes) (cksum - 3772623559) And so I was wondering if there is any limitation for large files... cos in AIX I cannot extract files grater than 2GB using cpio...

And So I thought i will extract here on the hp box and push it to the AIX box.

After I give the below command it just goes to next like and the cursor blinks there... like it dosen't do anything...

# cpio -idcmv 10gr2_aix5l64_database.cpio

Shalom,

You may have hit a size limitation, or used incorrect options.

cpio for HP-UX is slightly different that its Linux relative.

You also might wish to check the patch database for a cpio patch.

"and the size of the file is (1,268,576,110 bytes) (cksum - 3772623559) And so I was wondering if there is any limitation for large files... cos in AIX I cannot extract files grater than 2GB using cpio..."

so you're limited to 2GB, the file is smaller than that.

in following the link, I see you downloaded a gzip file (10gr2_aix5l64_database.cpio.gz (1,268,576,110 bytes) (cksum - 3772623559)"

did you even bother to run a "cksum" on the downloaded file to see if it downloaded properly? Or unzip it as specified in the directions?

"Directions
1. Unzip the file: gunzip
2. Extract the file: cpio -idcmv <
......"

If you unzipped it, how big is it now? There is (or at least was) a 2GB limit to sizes, but I believe that mean the size of an individual file within the archive.

"Thanks everyone... So I have left it as it is... it running since the last 20 minutes... Not really sure when it will stop execution".....

Define "left it as is". Did you get it running again, or did you leave it "stopped" as posted previously. If you left it "stopped", its not doing anything

disregard what I said regarding signals...I read SIGTSTP as SIGSTOP.

See what James had to say regarding Ctl-Q / Ctl-S instead.

[Grayh]

now it looks like it has hung and I will have to do a ^Z to get to the prompt as ^c or ^S dosent work...


Is there a way I can extract 10gr2_aix5l64_database.cpio file. if so how....

If any patches are reqyuired... plz tell .. me the patches name

[OldSchool]

now it looks like it has hung and I will have to do a ^Z to get to the prompt as ^c or ^S dosent work...

ok, so heres the thing, the Control-Z will stop the process, but not remove it. If you tried Control-c and it didn't work, it was probably i/o ing.

Refer to my previous post....did you ever verify the download w/ cksum?

Did you ever unzip it?

You shouldn't need patches....

Try to exctract the archive with pax - http://docs.hp.com/en/B3921-90010/pax.1.html

>JRF: The SIGTSTP stands for "terminal stop". You probably typed CTL_S to stop the process.

SIGTSTP is what you get when you use control-Z.

>OldSchool: in posix / ksh it can be resumed with the "fg" command

You can also resume it by using "bg" to put it in the background.

>So I have left it as it is

If you hit control-z, it is suspended. What does "jobs -l" and top show?

>OldSchool: disregard what I said regarding signals. I read SIGTSTP as SIGSTOP.

What you said was correct.

[Dennis Handly]

># cpio -idcmv 10gr2_aix5l64_database.cpio

Duh. The correct syntax (for reading stdin) is:
cpio -idcmv < 10gr2_aix5l64_database.cpio

That's probably why you should use Ivan's suggestion of using pax(1).
That "<" was on that URL.

[Grayh]

# cksum 10gr2_aix5l64_database.cpio
2491728778 1321110528 10gr2_aix5l64_database.cpio


wow pax has done a miracle...It worked

pax -rvf 10gr2_aix5l64_database.cpio

"That "<" was on that URL".

Nice catch Dennis...I looked at the OP more than once and didn't notice it was missing.

[Grayh]

Thanks everyone... I have overlooked "<" ..

But pax was a wonder..

Thanks again

[Dennis Handly]

>OldSchool: I looked at the OP more than once and didn't notice it was missing.

Neither did I until after I replied. Especially since everyone was looking at the control-Z output.
I did remember you can get the shell to help you figure this out, if you put it in the background:
$ cpio -i xx &
[2] 28077
$ jobs
[2] + Stopped (tty input) cpio -i xx &

Here it says it is waiting for stdin. And you ask yourself why?
