Agentless Scheduling

Introduction

The SSH (Secure Shell) JITL job (JobSchedulerSSHJob) allows a JobScheduler to execute programs on another computer without a JobScheduler Agent being installed on that machine.

The JobSchedulerSSHJob allows execution on Windows and Unix systems.

• The elegance of SSH is its simplicity. It allows public/private key authentication and is well suited to executing programs for specific accounts.
  • The JobScheduler SSH JITL job allows shell scripts to return values to JobScheduler orders as parameters.
    
    • See How To - Usage of the SSH Job (JobSchedulerSSHJob) with JCraft's JSch.
• One of the restrictions of standard SSH connections is that there is limited control of child processes on the remote host. 
  • If a number of child processes are spawned by a program during an SSH session and that session gets killed then these child processes would normally continue running.
  • The JobScheduler provides a method for monitoring SSH connections that allows both remote sessions and local JobScheduler tasks to be terminated.
    • See How To - SSH Session Management for more information.
• The JobScheduler provides a means of controlling the behavior of standard error output and exit codes of shell commands using the SSH JITL Job.
  • See Job JobSchedulerSSHJob - Handling StdErr and ExitCode for more information.
