external task system command
chrystel
Hi !
With TS6.1 SP1 / Windows 2000 server
I want to execute a script perl which may execute a system command "xcopy"
I run my perl script in a cmd window => it works (authenticated as an administrator)
As an external task => the xcopy doesn't work. (executed as user SYSTEM)
I verify the authorisation on xcopy (everyone full control).
I tried with a whoami cmd , it works ...
I don't know windows 2000 enough to have another idea ....
Thanks for your help or idea

You need to provide better, more detailed, diagnostics; "doesn't work" doesn't mean anything by itself.
How
doesn't it work?
What
happens?
What
does the code look like?
What
error messages, if any, exist in
which
log files?

Hi,
doesn't work = the xcopy seems to be ignored, no action, no trace, no error return code =0
WFT:
...
<command v="C:\iw-home\iw-perl\bin\iwperl.exe C:\iw-home\custom\bin\my_script.ipl -opt1=var1 -opt2=var2" />
.....
PERL:
my_script.ipl :
my %hCmd = (
'xcopy' => "xcopy $$hWkarea{WKUpdSrcPath} $$hWKarea{WkareaNTpatch} /I /E /C /R /Y",
.....
);
my %NTCmd = (
...
'sCmd' => "$hCmd{$$hWkarea{method}} 1>$$nomfic1 2>$$nomfic2 (where $$hWkarea{method} is xcopy)
);
processSystemCmd(\%hNTCmd);
.....
script.pm:
....
sub processSystemCmd {
....
chomp(
@aStdOut
= `$$href{sCmd}`
....
}
The command sCmd is logged and is well formed.
Is that better ???

I forget the end of the "chomp " line in my message but not in the script ....

Yes - that's better - now can you show us what the actual value of $$href{sCmd} is - from an actual debugging printout when it does work (from the command line) and when it doesn't work (from within a workflow externaltask) ?

Hello,
From a command line
2004-12-22 09:10:44|3044|3|- |chm_core_utilities|processSystemCmd|Executing : xcopy Y:\default\main\BrancheTST\EDITION\ed_0003 Y:\default\main\BrancheTSTxfer\WORKAREA\workTST /I /E /C /R /Y 1>F:/TeamSite/utils/setup/output/update_files_3044_1.txt 2>F:/TeamSite/utils/setup/output/failed_files_3044_1.txt
the file F:/TeamSite/utils/setup/output/update_files_3044_1.txt contains the file list copied
the file F:/TeamSite/utils/setup/output/failed_files_3044_1.txt is empty
All files are copied in the workarea WORKTST
From an external task
2004-12-22 09:11:37|1888|3|- |chm_core_utilities|processSystemCmd|Executing : xcopy Y:\default\main\BrancheTST\EDITION\ed_0003 Y:\default\main\BrancheTSTxfer\WORKAREA\workTST /I /E /C /R /Y 1>F:/TeamSite/utils/setup/output/update_files_1888_1.txt 2>F:/TeamSite/utils/setup/output/failed_files_1888_1.txt
the files are empty and files are not copied
I can't see any difference ?!

You might try using system() rather than back-ticks when running the command from within the script, or you might try prefacing the entire command string with: cmd /C "xcopy ....."
My guess is that the context/environment in which it is being (or attempted at being) run when used within a workflow externaltask is not identical to the context/environment you have when running from the command line yourself - and that more than likely it's not a case of xcopy failing - it's a case of xcopy not being recognized as a command and thus the back-ticks are essentially performing a no-op.

Hi,
I will try with system() thank you !
I've maid other tests and found that a command like whoami | xcopy ..... does work in the two cases ?! but whoami&xcopy not
Does it
Strange no !!!!!!
