About

This is a alternative and easy way to run scheduled tasks on Windows. It is useful to workaround access or group policy restrictions, for example if your group policy logs you out after a short period.
The script has been tested to run as service using srvany.exe .

Features

  • Can run scheduled programs every minute, hour, day or week
  • Protocol events in a xml file
  • Log all activities



Requirements

  • srvany.exe
  • Active State Perl >= 5.14
  • Additional Modules:
    • Win32::Process
    • Win32::Process::List


Installation

Unextract and copy the files to a directory of you your choice, this example is using c:\scheduled-task
These are the required script files:

  • c:\scheduled-task\st.pl
  • c:\scheduled-task\st.xml

Perl Modules

You need to have a recent version of active state perl installed, please run the installation commands:

ppm install Win32-Process
ppm install Win32-Process-list

Service Registration

Get the tool srvany.exe and copy it to c:\windows\system32\, then register the service by running:

sc create Perl-Scheduled-Task binPath= C:\Windows\System32\srvany.exe DisplayName= Perl-Scheduled-Task

Optional you may want to set a description for the service:

sc description Perl-Scheduled-Task "Schedule Task Manager for Perl"

Service Configuration

Open your registry and add the key Parmeters:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Perl-Scheduled-Task\Parameters]
  • Add a string value called Application within Parameters and add the path to perl and the path to the script:
"Application"="c:\\perl\\bin\\perl.exe c:\\scheduled-task\\st.pl -c c:\\scheduled-task\\st.xml"
  • Check your service permission, make sure the service user has enough permissions to start applications and has edit and create right in its application directory.



Script Configuration

Description of the configuration file used with st.pl.
Note: Please use the forward slash as a directory separator like on linux even on windows, this way we get no trouble with escape sequences.

Default Filename: st.xml

Security information: Please keep this file secure, only authorized accounts should be able to edit the configuration file.

st.xml
Element Array Attribute Description
System No ApplicationDirectory Path to appliactaion
StatusFile Path and Name to Status File, leave empty or set zero to disable
Log Path to Log Directory
LogAge Path to Log Directory
LogDirectory Path to Log Directory
ScheduledTask Yes Enabled Job enable (1/0)
Name Any Jobname
ApplicationPath Path to perl, eg: c:/perl64/bin/perl.exe
ApplicationParameter Path to the script, eg: c:/scheduled-task/st.xml
ApplicationPriority Available: Below or Normal
Mode Currently only Repeat
FrequencyUnit M=Every Minute
D=Daily
W=Weekly
FrequencyInterval Only with Mode=M, the interval in minutes for the scheduled task

Examples

  • Run 2 Jobs every 5 and every 2 minutes.

A XML status file is available to obtain the current status of the application, the file is read only.
Structure:
