Environment

  • Red Hat JBoss BPM Suite (BPMS) 6.4.x
    • Business-central as execution server;

Issue

  • How to trigger a stuck timer from a process instance running in business-central for JBoss BPM Suite 6.4.x?
  • After looking at the tables, it looks like process instance entered the timer node and it's never exited it;

Resolution

It is possible to set a timer as triggered. This way the process instance will continue the execution right after the timer. A sample project can be found attached, however, bear in mind that the attached project is supposed to be only a sample and that we don't provide support for it.

This sample project uses Java 8, so business-central must run with java 8. It is based on BxMS 6.4.2 (Maven library version: 6.5.0.Final-redhat-7). In order to run it, please apply the following steps:

  1. Build the project with mvn clean package
  2. Copy the jar from target dir to business-central.war/WEB-INF/lib

  3. Start the server and make a request in Jobs page to start a job that will run the custom command. Provide the processInstanceId and identifier (deployment_id where process instance is running), for example:

    3.1 Go to Deployments -> Job page;
    3.2 Create a New Job;

    Name: TriggerMyStuckTimer
Type: example.executor_update_timer.commands.SetTimerAsTriggeredCommand

    3.3 In Advanced tab add parameters:

    identifier - example:Test:1.0 (deployment_id where your process is running)
processInstanceId - 1

You should see the command being executed and the process instance continue its execution after it.

NOTE: The attached project is supposed to be only a sample and that means we do NOT provide support for it. We recommend to check the code to build your own project.
