Introduction

• The outage of an Agent will stop execution of workflows with that Agent. Workflows running with Agents that remain available are not affected.
• Workflows that miss their scheduled execution date will be executed when the Agent becomes available.

• Testing by SOS includes to perform tests for the scenario when an Agent becomes unavailable for 24 hours. Tests include to move the Agent's journal files to a new Agent after the 24 hours outage and to modify the Agent registration with JOC Cockpit. Then the new Agent executes any outstanding workflows of the previous day and any newly added orders.

• For information about the behavior in case of outages see JS7 - FAQ - What happens to workflows in case of outage of an Agent?

Troubleshooting

The Agent is the component in JS7 that executes workflows, stores information about execution results and order state transitions in its journal and passes results to the Controller. The outage of an Agent prevents execution of workflows.

An Agent outage can be handled either by resolving the issue with the current Agent, e.g. by restarting or by relocating the ./state directory to a different Agent provided that access to the same scripts and programs is available that should be executed. The Agent's journal is stored with this directory. To relocate the journal copy the journal files to a new Agent. Refer to the JS7 - Moving Components - Relocating an Agent article for the steps to apply.
