Example showing how to run a job chain with jobs that are to be run on different servers

Starting jobs on different servers using process classes for remote execution 

• JobScheduler can execute jobs on different servers.
• Such jobs can be distributed in a way that within one job chain the respective jobs are executed on different servers.

Example

• A job chain contains 3 jobs, i.e. TaskB1, TaskB2, TaskB3. 

• A user wants to configure TaskB1 to be executed on server ServerA (localhost), TaskB2 to be executed on server ServerB (Windows) and TaskB3 on server ServerC (Linux). 

• JobScheduler can execute jobs on remote JobScheduler instances, by JobScheduler Agents or by SSH. 

• In this example JobScheduler will execute jobs on remote JobScheduler instances using a process class. 

  • A JobScheduler process class is similar to a connection configuration where the remote JobScheduler's host name and port number are defined. 
  • With that process class being defined jobs can be configured to use the process class for remote execution.
  • JobScheduler will excute jobs on the remote JobScheduler instance and that instance will report back the status and the log to the local JobScheduler.
