Be sure that you set the PYTHONPATH environment variable in the
environment in which STAFProc is running (as opposed to the command line
environment in which you are submitting the STAF PROCESS START request).
This is because when running a command via STAF, the command is run in the
environment in which STAFProc is running, not in the environment of the
command line where you submitted the STAF PROCESS START request.
When debugging a problem using the STAF PROCESS START request to run a
command, I recommend that you redirect stdout/stderr for the command you
are running and specify the WAIT option to wait for the command to
complete so that you can immediately see the return code and stdout/stderr
result from running the command. For example, RC 2 (which is the return
code you were getting when running oldSTAFPython) is the Linux operating
system return code that means FileNotFound. You said you were running:
STAF local PROCESS START COMMAND python PARMS "oldSTAFTestcase"
This is incorrect as you need to specify the .py extension. Without the
.py extension, it will fail with RC 2 when running this python command
without using STAF as follows:
[root tmp]# python oldSTAFTestcase
python: can't open file 'oldSTAFTestcase': [Errno 2] No such file or
directory
[root tmp]#
Also, when running this command via STAF, you need to specify the path to
oldSTAFTestcase.py so that the system can find this file (e.g.
/tmp/oldSTAFTestcase.py). This is because when running a command via
STAF, the command is run in the environment in which STAFProc is running,
not in the environment of the command line where you submitted the STAF
PROCESS START request. So, for example, the following request (which is
like yours) fails with RC 2 (Linux operating system return code 2 means
FileNotFound) as follows because python cannot find file oldSTAFTestcase:
# STAF local PROCESS START COMMAND python PARMS oldSTAFTestcase
RETURNSTDOUT STDERRTOSTDOUT WAIT
Response
--------
{
Return Code: 2
Key : <None>
Files : [
{
Return Code: 0
Data : python: can't open file 'oldSTAFTestcase': [Errno 2] No
such
file or directory
}
]
}
#
However, if I correctly specify the full name of the file (e.g.
/tmp/oldSTAFTestcase.py), then the STAF PROCESS START request works fine.
Note I changed the count from 100 to 5 on oldSTAFTestcase.py so that it
would complete quickly when debugging this issue.
# STAF local PROCESS START COMMAND python PARMS /tmp/oldSTAFTestcase.py
RETURNSTDOUT STDERRTOSTDOUT WAIT
Response
--------
{
Return Code: 0
Key : <None>
Files : [
{
Return Code: 0
Data : OS Name: Linux
Loop # 0
Loop # 1
Loop # 2
Loop # 3
Loop # 4
}
]
}
#
Or, instead of fully-qualifying the path to the command, you could specify
the WORKDIR option with the directory where the oldSTAFTestcase.py file
resides. For example:
# STAF local PROCESS START COMMAND python PARMS "oldSTAFTestcase.py"
WORKDIR /tmp RETURNSTDOUT STDERRTOSTDOUT WAIT
Response
--------
{
Return Code: 0
Key : <None>
Files : [
{
Return Code: 0
Data : OS Name: Linux
Loop # 0
Loop # 1
Loop # 2
Loop # 3
Loop # 4
}
]
}
#
Note that I personally prefer using the COMMAND option to specify the
complete command instead of using the PARMS option. When you do this, you
must also specify the SHELL option. For example:
# STAF local PROCESS START SHELL COMMAND "python /tmp/oldSTAFTestcase.py"
RETURNSTDOUT STDERRTOSTDOUT WAIT
Response
--------
{
Return Code: 0
Key : <None>
Files : [
{
Return Code: 0
Data : OS Name: Linux
Loop # 0
Loop # 1
Loop # 2
Loop # 3
Loop # 4
}
]
}

Here, I am attaching files which producing above return codes. so
kindly help me.
When I am running the oldSTAFTestcase.py with python seperately,
it's working fine
Command: $ python oldSTAFTestcase.py
OS Name: Linux
Loop # 0
Loop # 1
Loop # 2
....
....
....
Loop # 97
Loop # 98
Loop # 99
But when i am running under staf environment it's giving response code 2.
I exported PYTHONPATH
export PYTHONPATH=/usr/local/staf/lib:${PYTHONPATH}
(oldSTAFTestcase.py exist in /usr/local/staf/lib)
Thanks & Regards,
