Re: [U2] Error 4 22 from PHP exec of uv on AIX

[John Thompson]

That is pretty much dead on.  Some things to note:

I decided not to go through the headache of compiling php and apache myself
on AIX.
There are some wonderful folks at a community college that created packages
for smit.

http://pware.hvcc.edu/

I typed up everything I did to get it installed, so
if anyone is interested, let me know.
The idea is not to use the AIX/Universe machine as a webserver, but, to use
Apache/PHP to receive requests from a webserver.

So its possible that the "pware" folks put that environment setting in their
build of apache.
I don't know enough about it to say one way or the other.

Whatever the case may be, you can find what apache and php are doing by
using the following php script, and calling it in a browser (NOT a shell).


";
echo system('/usr/ibm/uv/bin/uv 2>&1');  //Be sure and redirect stderr to
stdout.
echo 'AFTER Universe is executed' . "";

?>


The echo system('set'); and the redirection of universe's stderr to stdout
should let you see what is happening.

Then to actually get universe to fire up, you can just follow Kevin's
example.



This is on Universe 10.3.4 on AIX 5.3.  I'm guessing the same problem would
exist on version 11 too.  I did call our support with Rocket and they were
clueless, so I'll probably email it on over to them (just to be a good
messenger).

Also someone posted this link earlier from the IBM website.

Re: [U2] Error 4 22 from PHP exec of uv on AIX

[Kevin King]

When John and I were working on this we noticed that the LDR_CNTRL
environment variable wasn't set at all on a normal telnet login.  When we
DID set it manually on the telnet session, Universe wouldn't start with the
4 22 message.  So the simplest version the script was basically like this
(and forgive me as I'm reciting from memory):



John has been working on this more after we got this far so I'll defer to
him for more details. Note that all this script was proving was the ability
to start UV successfully from a PHP script invoked through Apache.  There is
more going on with moving data in and out of UV using JSON, which allows
massive amounts of structured data to be moved into and out of the
environment.

Re: [U2] Error 4 22 from PHP exec of uv on AIX

[fft2001]

LDR_CNTRL has to do with the settings for your temporary work space (as we used 
to call it)
How much space to allocate for your process' heap and so on.
Can you give a full PHP script showing how you got around this?
I mean the entire script, just post it into the board here.

Thanks for all of your replies.
Thanks to Bob Woodward for the shell environment idea.
Thanks to Kevin King for his help.

Apache sets extra environment variables when compared to the shell of a
regular user.

One of these environment variables is called:
LDR_CNTRL
Apparently it has something to do with the way AIX handles the memory space.
See:

http://publib.boulder.ibm.com/infocenter/javasdk/v6r0/index.jsp?topic=/com.ibm.java.doc.user.aix32.60/user/aix_ldr_cntrl_page_sizes.html

Apache seems to set the following when it starts a session:

LDR_CNTRL=MAXDATA=0x8000

If you set this to "null" in a php script, then Universe will run just fine.

Anyone have any ideas on the proper use of LDR_CNTRL?

This is shell variables, 

You will need $UVHOME and $UVBIN setting otherwise uv does not work.

I thought I would resurrect an old issue I found on the mailing list...

As I am not a mailing list junky (google and web forums have spoiled me),
I'm not entirely sure how to reply directly to the old post...

This is a bit of a stumper (for me, anyway).

I'm having issues trying to exec uv from PHP on AIX.

Things work just fine in Windows (Apache or IIS) or Linux (Apache) so I know
my PHP syntax is fine.

On the AIX (5.2 uv 10.2.7) box:

Using PHP, I can exec 'echo 1 + 2 | bc' and get 3
I can run this at the shell as user nobody: 'cd /u2/uv/HS.SALES;
/u2/uv/bin/uv "display 42"'
I can get a CGI script to return 'cd /u2/uv/HS.SALES; /u2/uv/bin/uv "display
42"' correctly

With PHP, I can't exec ' /u2/uv/bin/uv "display 42"' (after a chdir).

UV throws this error (into the Apache logs):

An error has occurred during uniVerse initialization
Please contact the system administrator Error code: 4 22

The codes translate into:

4. System V semaphores are probably not configured in the kernel.

22. (EINVAL) Invalid argument. Here are some examples of invalid
arguments: dismounting a nonmounted device, mentioning an unknown
signal in signal, reading or writing a file for which seek has generated a
negative pointer. EINVAL is also set by math functions.

Has anyone else bumped into this?  IBM support suggested it might be an
issue with SIGTTOU but this seems unlikely to me - especially for a one-line
command.  PHP is a bit outside their bailiwick.

Thanks, Ross.

End of Original Post 


I am having the exact same problem.  I have tried using nohup before
called universe.

There is something about when apache calls the php script, then the
php script executing universe, that universe does not like...

Anyone ever figure out a way around this?

Thanks for all of your replies.

Thanks to Kevin King for his help.

Apache sets extra environment variables when compared to the shell of a
regular user.

One of these environment variables is called:
LDR_CNTRL
Apparently it has something to do with the way AIX handles the memory space.
See:

http://publib.boulder.ibm.com/infocenter/javasdk/v6r0/index.jsp?topic=/com.ibm.java.doc.user.aix32.60/user/aix_ldr_cntrl_page_sizes.html

Apache seems to set the following when it starts a session:

LDR_CNTRL=MAXDATA=0x8000

If you set this to "null" in a php script, then Universe will run just fine.

Anyone have any ideas on the proper use of LDR_CNTRL?

this sounds like a permissions issue.

probably, the user that apache is running under doesn't have the permissions

As a workaround, you could try u2pipe:

http://www.pickwiki.com/cgi-bin/wiki.pl?U2pipe

You wouldn't need to install it as a inet service, just use it as a
pipe.  For example:

echo "display 42"|/usr/local/bin/u2pipe (or wherever you install it)

To configure u2pipe, you edit /etc/u2pipe.ini to enter the user,
password, and account.  Any commands you pipe to it will run in
universe and the output will go to stdout.

Re: [U2] Error 4 22 from PHP exec of uv on AIX

[Bob Woodward]

Sounds to me like it has something to do with shell environment not
being what is expected.  Something like maybe the path doesn't include a
needed directory.  I'm not a PHP programmer, though, so it's just a WAG
on my part.

Yep, the same behavior still happens.

The issue is:

On AIX 5.3 (Technology Level 9)
You can do the following:

-Call Universe from a php script from a shell.
So if I do:
php -f scriptname.php
The php script, is changing the directory and firing up universe.

Everything works fine from the shell.

-If I run that same script through the browser (i.e. Apache 2.2 on AIX),
then universe will crash with:

An error has occurred during uniVerse initialization
Please contact the system administrator
Error code:  4  22

Rocket's suggestion is to run it with nohup, which did NOT work.

Its not a permissions issue.  I made them wide open (777) as a test, and
I
can call the php script from the shell of the user that Apache runs as,
and
they work fine- Universe fires up and does its thing.

Universe does not get to the point to where it can even call the login
proc.
 It crashes before it can even start.

Have you tried "&&" instead of ";" to separate the cd and uv commands?

[U2] Error 4 22 from PHP exec of uv on AIX

[John Thompson]

I thought I would resurrect an old issue I found on the mailing list...

As I am not a mailing list junky (google and web forums have spoiled me),
I'm not entirely sure how to reply directly to the old post...

Original Post 
From:

Ross Morrissey
Fri, 24 Jul 2009 14:11:56 -0700

This is a bit of a stumper (for me, anyway).

I'm having issues trying to exec uv from PHP on AIX.

Things work just fine in Windows (Apache or IIS) or Linux (Apache) so I know
my PHP syntax is fine.

On the AIX (5.2 uv 10.2.7) box:

Using PHP, I can exec 'echo 1 + 2 | bc' and get 3
I can run this at the shell as user nobody: 'cd /u2/uv/HS.SALES;
/u2/uv/bin/uv "display 42"'
I can get a CGI script to return 'cd /u2/uv/HS.SALES; /u2/uv/bin/uv "display
42"' correctly

With PHP, I can't exec ' /u2/uv/bin/uv "display 42"' (after a chdir).

UV throws this error (into the Apache logs):

An error has occurred during uniVerse initialization
Please contact the system administrator Error code: 4 22

The codes translate into:

4. System V semaphores are probably not configured in the kernel.

22. (EINVAL) Invalid argument. Here are some examples of invalid
arguments: dismounting a nonmounted device, mentioning an unknown
signal in signal, reading or writing a file for which seek has generated a
negative pointer. EINVAL is also set by math functions.

Has anyone else bumped into this?  IBM support suggested it might be an
issue with SIGTTOU but this seems unlikely to me - especially for a one-line
command.  PHP is a bit outside their bailiwick.

Thanks, Ross.

End of Original Post 


I am having the exact same problem.  I have tried using nohup before
called universe.

There is something about when apache calls the php script, then the
php script executing universe, that universe does not like...

Anyone ever figure out a way around this?

Thanks Symeon, that looks very similar to what I'm doing - and what works
flawlessly on Linux/Apache, Windows/Apache, and Windows/IIS!!!  The darn

This is a snip from my php handler for a unidata program

$udtCmd="LANG=en_US.UTF-8;export LANG; cd
/usr/ud/accounts/$account;/usr/ud71/bin/udt RUN $BP flyGen $noads $style
$uid $keywords -G";
$result = array();
$i=1;
$done=0;
$time_start = microtime(true);
exec( $udtCmd, &$result);
$time_end = microtime(true);
foreach ( $result as $v )
{




Notice i do set an env var in the same command as the udt command and i put
the full path in as well. This works fine.

Thanks Henry, this sent me down another path of exploration.  I ran my PHP

fine - which makes it difficult to debug further.  I was able to compare
user and environment variables and there are no smoking guns.  If I can't

Good guess, but I *always* use the full path to executable when I'm using

This is a bit of a stumper (for me, anyway).

I'm having issues trying to exec uv from PHP on AIX.

Things work just fine in Windows (Apache or IIS) or Linux (Apache) so I know

On the AIX (5.2 uv 10.2.7) box:

I can run this at the shell as user nobody: 'cd /u2/uv/HS.SALES;

I can get a CGI script to return 'cd /u2/uv/HS.SALES; /u2/uv/bin/uv "display
42"' correctly

With PHP, I can't exec ' /u2/uv/bin/uv "display 42"' (after a chdir).

UV throws this error (into the Apache logs):

An error has occurred during uniVerse initialization
Please contact the system administrator Error code: 4 22

The codes translate into:

4. System V semaphores are probably not configured in the kernel.

22. (EINVAL) Invalid argument. Here are some examples of invalid
arguments: dismounting a nonmounted device, mentioning an unknown
signal in signal, reading or writing a file for which seek has generated a
negative pointer. EINVAL is also set by math functions.

Has anyone else bumped into this?  IBM support suggested it might be an
issue with SIGTTOU but this seems unlikely to me - especially for a one-line
command.  PHP is a bit outside their bailiwick.
