Hi all, I am trying to switch to AsyncExecutor and want to set it up in a clustered mode (enabled on all servers). My process engine configuration looks like this:
@Bean(name = "processEngineConfiguration")
public ProcessEngineConfigurationImpl processEngineConfiguration() {
SpringProcessEngineConfiguration processEngineConfiguration = new SpringProcessEngineConfiguration();
processEngineConfiguration.setClassLoader(getClass().getClassLoader());
processEngineConfiguration.setDataSource(dataSource()); // This is a postgres DB
processEngineConfiguration.setDatabaseSchema(activitiSchema); // Have a separate schema for activiti
processEngineConfiguration.setDatabaseSchemaUpdate("true");
processEngineConfiguration.setTransactionManager(annotationDrivenTransactionManager());
processEngineConfiguration.setJobExecutorActivate(false);
processEngineConfiguration.setAsyncExecutorEnabled(true);
processEngineConfiguration.setAsyncExecutorActivate(true);
processEngineConfiguration.setHistory("full");
processEngineConfiguration.setMailServerHost(mailServer);
processEngineConfiguration.setMailServerPort(mailServerPort);
return processEngineConfiguration;
}
But when I tested a workflow with two servers, I saw both servers executed a task from the same process instance. Is this expected? How can I configure the process engine so that only one server executes any given task?Thanks,Sankalp
