Whether month end process can be automated in progress bases applications like nessie? I already searched for it and I think maybe it can done by scheduling it through background jobs.
Scheduling jobs is a function of the OS or of 3rd party applications that specialize in such things (generally used in large enterprises with IT groups that obsess over that kind of stuff).
If you are using UNIX then you want to look into "cron".
If you are using Windows then "scheduled tasks".
In any event you will need to create a "wrapper" script that properly sets the background job environment and launches a Progress session. If you are using Windows you should be aware that a batch process is "headless" and that unless your batch process is doing something very strange it will not be using GUI components -- so you should probably run _progres.exe rather than prowin32.exe.
A generic (UNIX) example:
#!/bin/sh
#
DLC=/usr/dlc
PATH=$DLC/bin:$PATH
export DLC PATH
_progres -b -db /path/dbname -p batchjob.p > logfile 2>&1 &
(That is "_progres" with just 1 "s" -- this is from the days when file names were restricted to 8 characters on some operating systems.)
Windows is very similar:
# echo off
set DLC=c:\progress
set PATH=%DLC%\bin;%PATH%
_progres.exe -b -db \path\dbname -p batchjob.p > logfile 2>&1
But there are a lot of "gotchyas" with Windows. If, for instance, you run a job using a login-id that might actually login then you will have the problem that on logout all the scheduled tasks will be "helpfully" killed by the OS. Aside from stopping your job when you probably don't want it to this may have other negative side effects like crashing the db. To get around that problem on Windows you either create a "service account" that never logs in or use 3rd party scheduler that runs jobs "as a service".
I am able to execute scrip from command line.
I'm executing it like this:
/path/to/script run
But while executing it from cron like below, the page is not comming:
55 11 * * 2-6 /path/to/script.pl run >> /tmp/script.log 2>&1
The line which is getting a webpage uses LWP::Simple:
my $site = get("http://sever.com/page") ;
I'm not modyfing anything. The page is valid and accessible.
I'm getting enpty page only when I execute this script from crontab. I am able to execute itfrom command line!
Crontab is owned by root. And job is executed as root.
Thanks in advance for any clue!
It's difficult to say what might be causing this, but there are differences between your environment, and the environment created by crontab.
You could try running it through a shell with appropriate args to construct your user environment:
55 11 * * 2-6 /bin/tcsh -l /path/to/script.pl run >> /tmp/script.log 2>&1
I'm assuming you are running it by cron with your own user ID of course. If you aren't, then obviously you should try running it manually with the user ID that cron is using to run it.
If it's not a difference in environment variables (e.g. those that specify a proxy to use), I believe you are running afoul of SElinux. Among other things, it prevents background applications (e.g. cron jobs) from accessing the internet unless you explicitly allow them to do so. I don't know how to do so, but you should be able to find out quite easily.
I am new to using cygwin and don't really understand how the scripting of it works. Currently I am running it on Windows 7 and using task scheduler to do this inefficiently.
What I want to do is to run a .bat file already made that runs tests in the cmd line and than take the results of that test and email that people.
Some side notes:
1. It doesn't HAVE to be a batch file, from my reading I think maybe a .sh would be easier to run with bash. Being able to run it on CentOS would be even better, that way others can run if I leave.
2. This needs to run daily. I would like to run the batch file at around 10 am and give it an hour till the emailed results are sent, unless you can trigger the email when the .bat is done.
3. Every time I run this .bat file it saves the results to a .htm file and overwrites it every time the .bat is run.
Thank you
That could be in the crontab for a a centOS server (/etc/crontab)
0 10 * * * user cd /path/ && /bin/bash file.sh >> result_file
Is that what you needed ? Also, you can install Cron as a windows service with cygrunsrv
I have a perl script that I run from the command prompt: 3 times a day, the problem is now I need to run it every two hours. Im not going to be on an episode of lost so I need some help. Here is the command:
Perl C:/test/scripts/edi.pl
Does anyone know how this above one line command can be made into an executable (.exe) file so I can use the task scheduler to run?
If there is another way to do this with the task scheduler to run once every two hours every day then I could do that as well.
Thanks for your time.
Can you not simply create a batch file that runs the script, and set that batch file to run every two hours? I know from a quick test there that I can schedule a batch file to run from Task Scheduler on Windows XP at least.
You can actually use the task scheduler to run that exact command without a batch.
The task scheduler should allow you to pass some arguments to the script without a problem (I have done this on a few Windows servers in order to have them run PHP scripts)
I have a Perl script that contains this code snippet, which calls the system shell to get some files by SFTP and unzip them with WinZip:
# Run script to get files from remote server
system "exec_SFTP.vbs";
# Unzip any files that were retrieved
foreach $zipFile (<*.zip>) {
system "wzunzip $zipFile";
}
Even if some files are retrieved, they are never unzipped, because by the time the files are retrieved and the SFTP connection is closed, the Perl script has already completed the unzip step, with the result that it doesn't find anything to unzip.
My short-term fix is to insert
sleep(60);
before the unzip step, but that assumes that the SFTP connection will finish within 60 seconds, which may sometimes be a gross over-estimate, and other times an under-estimate.
Is there a more sound way to cause Perl to pause until the SFTP connection is closed before proceeding with the unzip step?
Edit: Responders have questioned (and reasonably so) the use of a VB script rather than having Perl do the file transfer. It has to do with security -- the VB script is maintained by others and is authorized to do the SFTP.
Check the code in your *.vbs file. The system function waits for the child process to finish before execution continues. It appears that your *.vbs file is forking a background task to do the FTP and returning immediately.
In a perfect world your script would be rewritten to use Net::SFTP::Foreign and Archive::Extract..
An ugly quick-hackish kind of way might be to create a touch-file before your first system call, alter your sftp-fetching script to delete the file once it is done and have a while like so
while(-e 'touch.file') {
sleep 5;
}
# foreach [...]
Of course, you would need to take care if your .vbs fails and leaves the touchfile undeleted and many other bad side effects. This would be for a quick solution (if none of the other suggestions work) until you get the time to rewrite without system() calls.
You need a way for Perl to wait until the SFTP transfer is done, but as your script is currently written, Perl has no way of knowing this. (It looks like you're combining at least two scripting languages and a (GUI?) SFTP client; this can work, but it's not exactly reliable or robust. Why use VBscript to start the SFTP transfer?)
I can think of four options:
Your Perl script could do the SFTP transfer itself, using something like CPAN's Net::SFTP module, rather than spawning an external job whose status it cannot track.
Your Perl script could spawn a command-line SFTP utility (like PSFTP) that doesn't return until the transfer is done.
Or change exec_SFTP.vbs script to not return until the transfer is done.
If you're currently using a graphical SFTP client and can't switch for whatever reason, I'd recommend using a scripting language like AutoIt instead of Perl. AutoIt has features to wait for windows to change state and so on, so it could more easily monitor for an activity's completion.
Options 1 or 2 would be the most robust and reliable.
The best I can suggest is modifying exec_SFTP.vbs to exit only after the file transfer is complete. system waits for the program it called to complete, so that should solve your problem:
system LIST
system PROGRAM LIST
Does exactly the same thing as "exec LIST", except
that a fork is done first, and the parent process
waits for the child process to complete.
If you can't modify the vbs script to stay alive until it terminates, you may be able to track subprocess creation. If you get subprocess ids, you can monitor them thereby know when the vbs' various offspring terminate.
Win32::Process::Info lets you get a subprocess ids from a running process.
Maybe this is a dumb question, but why not just use the Net::SFTP and Archive::Extract Perl modules to download and unzip the files?
system will not return until the shell it's running the command in has returned; this may be wrong for launching graphical programs and file associations.
See if any of the following help?
system('cscript exec_SFTP.vbs');
use Win32::Process;
use Win32;
Win32::Process::Create(my $proc, 'wscript.exe',
'wscript exec_SFTP.vbs', 0, NORMAL_PRIORITY_CLASS, '.');
$proc->Wait(INFINITE);
