Restart and resume flow services
Use restart and resume to control the run of flow services after a failure or interruption.
IBM® webMethods Integration provides functionality to restart or resume failed flow service executions. If an execution fails, it can be resumed from the point of failure. Resuming an execution does not run the previously successful operations but runs only the failed operations and operations that are not yet ran. When a flow service execution is restarted, the execution occurs from the beginning.
-
The Restart and Resume options are available upon request for a tenant. Contact IBM support.
-
The Restart and Resume options are not available for flow services that are created through Swagger (REST APIs) and WSDL (SOAP APIs).
-
If a flow service is invoked through a Messaging subscriber, then the Restart and Resume options are not applicable.
The following table provides information on when you can restart or resume a flow service execution:
| Execution Result Status | Restartable | Resumable |
|---|---|---|
| Successful Executions | Yes | No |
| Failed Executions | Yes | Yes |
| Completed with Errors | Yes | No |
| Running Executions | No | No |
-
You can restart one or multiple flow services as per your requirements.
-
If a flow service has only the restart capability that is enabled, resuming it from the flow service Executions listing page will also trigger a restart of the execution instead of resuming from the point it failed in the previous run.
-
The flow service executions list displays two buttons in the Actions column for the relevant execution: Restart and Resume.
