FAQ

JIT Scheduler contains the Bug report generator ("Diagnostics" in the "Services" menu). It collects some information on the Program and System and generates a report. It is recommended to attach this report to e-mail message, if you have problems with software and going to ask author about it via e-mail. It will help author to solve the problem. Tasks from Schedule can be also included to this report. Just select the tasks you want author to review before generating the report.

Q: How to specify file names and command line parameters correctly ?

A: As you know, (I hope you know) Windows supports Long File Names, which can also contain spaces. Such names should be quoted ( " - character). JIT Scheduler quotes it automatically, if Type of Task is set to "Application". So, you have to quote it manually, if you are going to run program with command line parameters. There are some rules here :

• Application name should be quoted separately of command line parameters.

• If command line parameters contain Long File Names, it should be also quoted.

• I also recommend to specify full file path and name.

• Never quote file names and never specify command line parameters in Document task.

Note, that two text strings separated by space will get to two command line parameters. If these two words are quoted they will get to one command line parameter.

Here some examples :

"C:\My Folder\program.exe"

"C:\My Folder\program.exe" "D:\somefile.txt"

"C:\My Folder\program.exe" param

"C:\My Folder\program.exe" param1 param2 - here we have two parameters

"C:\My Folder\program.exe" "param1 param2" - here we have one parameter

The quoting of file names was not invented by me. It is used by Windows. You can see such quoting in shortcuts, File Types properties and even in MS-DOS Prompt. Space separates executable name and parameters. So, it is not easy for programs to determine whether space is a separator or just the symbol in file name. Quoting allows to specify where the file name begins and where it ends.

Q: What to do if it doesn't work?

A: JIT Scheduler doesn't execute task in expected time. First of all, make sure that Schedule Executive sched.exe (schednt.exe) is running. Search for JIT Scheduler's icon in the System Tray on the TaskBar. It is recommended to start sched.exe at System startup. There is special option - "Run JIT at System startup" in "Options" dialog. It should be turned ON. When this option is enabled Program creates the "JITScheduler" value in "HKEY_CURRENT_USER\SOFTWARE\Microsoft \Windows\CurrentVersion\Run" key in System Registry. This key allows to start applications automatically. If you have problems with Registry try to include sched.exe to the StartUp folder in the Start Menu.

If Schedule Executive is running you should check the Activity flags of whole Program and task. They should be active.

You may also check "Warn about task launching" option and test if Program attempts to execute task or not. If it asks about launching but doesn't execute it means that something wrong with the Operating System. It sometimes happens while executing DOS or Win 3 executables. Try to check corresponding system settings. If "Report about execution errors" option enabled, JIT Scheduler reports about errors.

Q: What does it mean - "There is no registered System Schedule" ?

A: The name of System Schedule file must be specified in the DAT string value in "HKEY_LOCAL_MACHINE\ SOFTWARE\Polyakoff\JIT Scheduler 4\Scheduler" registry key. The impossibility to read this value means that there is no registered System Schedule.

Possibly System Scheduler was not installed or information in Registry has been lost.
