How can JobScheduler access files that are owned by another user?

Changing the UserID used by JobScheduler

Question

One of the files on our file system has an owner that is different to the user ID used by our JobScheduler.
This is causing the following errors:

 2012-10-15 18:26:27.360 [info]   SCHEDULER-918  state=starting (at=2012-10-15 18:26:27.333)
 2012-10-15 18:26:27.361 [info]   SCHEDULER-987  Starting process: '/bin/sh' '-c' '"/tmp/schedule/sos.w6p0JW"'
 2012-10-15 18:26:27.475 [info]   /tmp/schedule/sos.w6p0JW: line 4: ./TDloadFIM: Permission denied
 2012-10-15 18:26:27.475 [info]   SCHEDULER-915  Process event
 2012-10-15 18:26:27.476 [ERROR]  SCHEDULER-280  Process terminated with exit code 126 (0x7E)

I noticed there is a SETUID that could be used, I have looked through the FAQ, could you give us some information please as this could fix our issue?

Answer

There are two possible solutions if you are running on Unix:

• Use sudo in the JobScheduler job : sudo -u other_user script_for_other_user.sh

   Make sure that other_user don't need a password for sudo. For this edit the _sudoers_ file.
  

• If the owner of the file you want to access does not have to authenticate with a password, you can use the sudo command within a script job.
• Use the JobScheduler's setuid executible. This is described:
  • in English Is JobScheduler able to run jobs as a specific userid?
  • in German Kann der Scheduler Jobs in unterschiedlichen Benutzerkennungen ablaufen lassen?

If the file system you are accessing is on another computer and all the files you are acessing have the same owner you can either use SSH or a JobScheduler Agent.
