Re: [staf-users] STAF running but does not return command output

If the date command is failing soon after a reboot, then my guess is that 
the date command, or STAFProc itself (as a process started via STAF runs 
in STAFProc's environment) needs something which hasn't been started or 
initialized yet on reboot.


When STAFProc first starts, it starts the STAFProcessMonitorThread.  You 
said that you're seeing message "STAFProcess::processMonitorThread: Error 
opening /dev/tty, errno: 6" in the STAFProc output.  Error code 6 means 
that /dev/tty does not yet exist.  This may be because of the way you're 
starting STAFProc when booting up -- such that it is being started too 
soon, where devices haven't been initialized yet, etc., 

You may need to use a different method to start STAFProc on reboot so that 
it starts up later in the boot cycle.

Re: [staf-users] STAF running but does not return command output





I'm lazy, so in this case - RedHat 5 - I just used rc.local:

# cat /etc/rc.d/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local
/usr/local/staf/startSTAFProc.sh

A lot of my tests involve reboots or (clean and unclean/power-cycles).  I 
am not sure if this error occurs soon after a reboot, but I believe it 
actually does.

Thanks,
Paul

Paul,

On this system, are you starting STAFProc during reboot?  That error 
message can occur when STAFProc is started during reboot, and the message 
doesn't really indicate that there is a problem with STAF.  We have 
sometimes found that the method used to start STAFProc during reboot can 
have some side effects when running processes via STAF.  Can you show us 
the exact system file updates you have made to start STAFProc during 
reboot?  Can you retry your tests when you start STAFProc manually after 
the reboot, and assuming they work correctly, try rebooting the system so 
that STAFProc starts automatically, and then run the tests again to see if 
the problem occurs?  This would help us narrow down the problem.
 
Thanks, 
David

Re: [staf-users] STAF running but does not return command output



It has shown up again. This is a Linux box. STAF was working fine and a 
STAX job was running (STAX machine is separate) and interacting with two 
Linux machines. One of them began having this error randomly, as far as I 
can tell; it successfully was running processes 14 seconds earlier.

It looks like, from the nohup.out file, this is the "cause" of the 
failure, especially since it appears to only effect the process service:

-- snip --
Startup time : 20100128-17:49:35

It looks like the AIX box had some funny things going on. I restarted STAF 
on it and now it's working ok.

After restarting STAF, I'm not sure I have any more servers in the strange 
state. I'll e-mail again if it happens to a server that is already working 
ok. :)

Thanks,
Paul

Try adding the STDIN option specifying an empty file, e.g. /tmp/empty.txt, 
you created on the machine where the process is running, e.g. on 
sjpwr5c2c. Does that make a difference?

STAF sjpwr5c2c PROCESS START SHELL COMMAND "date" RETURNSTDOUT 
STDERRTOSTDOUT STDIN /tmp/empty.txt WAIT

The first return code of 1 doesn't always show up. Here's another machine 
that it's happening, this time STAF is running on AIX.

[r...@sjx86098 ~]# staf sjpwr5c2c process start shell stderrtostdout 
command "date" returnstdout wait
Response
--------
{
Return Code: 0
Key : <None>
Files : [

[r...@sjx86098 ~]# staf sjpwr5c2c ping ping

PONG

Re: [staf-users] STAF running but does not return command output


First, add option STDERRTOSTDOUT so that you can see if there's any 
additional error information when it fails.

Also, try adding option SHELL. For example: STAF local PROCESS START SHELL 
COMMAND "date" RETURNSTDOUT STDERRTOSTDOUT WAIT

[staf-users] STAF running but does not return command output





This has happened both right after starting STAF as well as after it 
already has been working.

It appears to mainly affect starting processes. STAF pinging it works. 
Here's an example of the failure:

sjx64ycle:~ # staf local process start command "date" returnstdout wait
Response
--------
{
Return Code: 1
Key : <None>
Files : [
{
Return Code: 0
Data :
}
]
}

It should be:
[r...@sjx86098 ~]# staf local process start command "date" returnstdout 
wait
Response
--------
{
Return Code: 0
Key : <None>
Files : [
{
Return Code: 0
Data : Thu Jan 28 10:19:12 PST 2010

}
]
}

Any ideas?

Thanks,
Paul E.
