How To Synchronize Job Execution Across Job Chains

Scope

This article is about methods that can be used with the JobScheduler for synchronizing the execution of jobs in Job Chains.

See the How to Execute Jobs in a Job Chain in Parallel article for methods about executing jobs within a job chain in parallel. This method is available for JobScheduler Versions 11.4 and newer and uses significantly less resources than synchronization.

Methods for Synchronization of Jobs in different Job Chains

The JobScheduler can use a number of methods to synchronize the execution of jobs in different job chains.

Static Configuration

• For the static configuration of the parallel execution of jobs:
  • Using JITL split and sync jobs:
    • Example showing how to set up a splitter job
    • Example showing how to set up a sync job
    • Example showing the synchronization of multiple job chains
    • How to start a job chain with a time event and only when another job chain has finished

Dependencies Across Job Chains

• For the configuration of complex dependencies between jobs and orders across job chains:
  • Use backward dependencies:
    • How to Configure Backward Dependencies in Jobs and Job Chains
  • Use event handlers to implement dependencies between job chains:
    • Event handling for job dependencies
    • How To - Event Handling
    • How to use the JobScheduler event handler in a complex job chain
