Issue/Introduction
We have an application that re-triggers itself at the end of the application with this javascript -->
...execTrigger('%APPL._event');
We are experiencing an issue where it doesn't re-trigger. In the tracelog, I am seeing this message -->
20230106 09:49:21.152 [ss:tdr] [WARN] SS.sequential_event_trigger_1825: [2023-01-06_09:49:21.152] Event ADMIN.<APPL_NAME> cannot be triggered, it currently holds an active application.
Environment
Release : 12.1
Cause
The event had the flag "Do not trigger if active" selected.
Resolution
To resolve this issue:
- Open the properties for the event.
- Go to the "Schedule" page.
- Deselect the option "Do not trigger if active"
Warning:
Using the javascript documented in the description may generate an infinite loop of application generations to be created - which may lead to eventually crashing the DE Server/Service (as it may quickly reach the active.appl.gen.stop limit). If using the javascript documented, please be sure to execute it with other conditions and/or with the Application configured to use the "Wait for previous generation" option - which will cause the new application generation to start in APPLWAIT state.
Additional Information
If an event is triggered while the Event's "Do not trigger if active" checkbox is selected AND there is an active generation, the tracelog.txt will have the following message:
sequential_event_trigger_1825: [2023-01-06_09:49:21.152] Event ADMIN.<APPL_NAME> cannot be triggered, it currently holds an active application.
If an event is triggered while the Application's "Do not trigger if active" checkbox is selected AND there is an active generation, the tracelog.txt will have the following message:
sequential_event_trigger_7: [2023-01-06_19:05:09.022] Application <APPL_NAME> cannot be generated, it is currently active.
