AM working on camunda bpm 7.3 with eclipse plugin camunda modeler 3.0.0 am clearing the all war files in webapps but still in processes it showing the processes how to remove the old task process from cockpit please help me
and my env is :
os:ubuntu 14.0.4
eclipse:Luna
tomacat:7.x
camunda:7.3
camunda modeler:3.0.0
See the reference[1] for the processes.xml file. Setting the property 'isDeleteUponUndeploy' to true will delete everything from that deployment when you undeploy the WAR. It that what you are looking for?

Embedded;
if you know which taskId is active, you can get list of them; then delete with cascade true.
taskService.deleteTask(task.getId, true)
or you can give your task DueDate and you can delete with cascade after get your active TaskList
List<Task> taskList = taskService.createTaskQuery().dueBefore(new Date()).active().list();
for (Task task : taskList) {
taskService.deleteTask(task.getId, true);
}

the azure webjob with runmode set to "onDemand" keeps running and I am not able to stop it.
I don't see anything that needs to be handled but the job.
{
"$schema": "http://schemastore.org/schemas/json/webjob-publish-settings.json",
"webJobName": "ScheduledJob",
"runMode": "OnDemand"
}
ScheduledJob Triggered Running n/a
the only way to restarted is by restarting the web service. Then start the job manually. And then it keeps running. It does not stop.
What is going on with this webjob?
Update1:
I am using the code from Pnp Partner package which can be found here.
As the code is two long I am just providing the code in the program.cs file.
For the rest please have a look at the I posted above.
static void Main()
{
var job = new PnPPartnerPackProvisioningJob();
job.UseThreading = false;
job.AddSite(PnPPartnerPackSettings.InfrastructureSiteUrl);
job.UseAzureADAppOnlyAuthentication(
PnPPartnerPackSettings.ClientId,
PnPPartnerPackSettings.Tenant,
PnPPartnerPackSettings.AppOnlyCertificate);
job.Run();
#if DEBUG
Console.ReadLine();
#endif
}
In your code, the PnPPartnerPackProvisioningJob class is inheritted from TimerJob class.
In TimerJob class, there is not a stop method. And if timer job has started executing, you can not really stop it unless you restart web jobs. For more details, you could refer to this article.
So if your requirement is to cancel a job, you will need to delete the timer job definition. However if timer job has started executing, you can not really STOP it unless you reset IIS or stop Sharepoint Windows Timer Service.
I've seen some guidance around using settings.job for this but it's not working - in the console I see:
WebJob singleton setting is False
How can I go about preventing scale-outs from running multiple instances of my webjob?
As far as I know, to set a continuous job as singleton, we could create a file called settings.job with the content: { "is_singleton": true } and put it at the root of the WebJob directory.
And we could get continuous job settings to make sure whether it is singleton.
GET /api/continuouswebjobs/{job name}/settings
in the console I see:
WebJob singleton setting is False
Please use Kudu tool to check whether the settings.job is existing at the root of the WebJob directory and the actual value of “is_singleton” property.
If you can use the WebJobs SDK, I prefer to use the Singleton attribute.
https://learn.microsoft.com/en-us/azure/app-service/webjobs-sdk-how-to#singleton-attribute
[Singleton]
public static async Task ProcessImage([BlobTrigger("images")] Stream image)
{
// Process the image.
}
If you have something like a ServiceBus trigger you should use [Singleton(Mode = SingletonMode.Listener)] in combination with the other host settings.
I registered my task app in Spring Cloud Data Flow, created a definition for it and the status shows 'unknown'. I created the stream and trying to launch the task through task-sink and I get an error:
java.lang.IllegalStateException: failed to resolve MavenResource:
How to launch a task from the task-sink? Am I missing something? Any help is appreciated. Another question I have is how do I access the payload sent via TaskLaunchRequest in my task?
S1 http | step1: transformer-rabbit | log
S2 :S1.step1 > filter --expression=payload.contains('CUSTADDRMODRQ_V15') | task-processor | task-sink
task-sink is launching the task provided by the uri in the TaskLaunchRequest. It is looking for the resource as shown in the log
OUT Using manager EnhancedLocalRepositoryManager with priority 10.0 for /home/vcap/.m2/repository
OUT Using transporter HttpTransporter with priority 5.0 for https://repo.spring.io/libs-snapshot and finally failing.
The task is deployed in our repository and as mentioned I registered and created the definition for it as well.
This one is in cf environment and I am using SCDF server 1.0.0.M4.
In the application.properties for the task-sink i am providing maven.remote.repositories.snapshots.url=**
task create fis-ifx-event-task --definition "fis-event-task"
My goal is launching the task from the stream.
Thanks for the information. I am in fact using the BUILD-SNAPSHOT as I am unable to enable taks in 1.0.0M4 version. Here is the one I am using spring-cloud-dataflow-server-cloudfoundry-1.0.0.BUILD-20160808.144306-116. I am able to register and create task definitions. The status of the task definition is showing as 'unknown' even when I am using the sample task module provided by your team. But when I initiate the flow of the stream and when task-sink tries to launch the task, it is unable to find the maven resource. When I create the task definition, does the task module gets deployed? I don't see any app in Pivotal Apps Manager. As mentioned earlier, I provided maven.remote.repositories.snapshot.url in the application.properties file for the task-sink application. Another thing I observed is when I launch the task manually from dataflow shell it gives an error CF-UnprocessableEntity(10008): The request is semantically invalid: Unknown field(s): 'staging_disk_in_mb', 'staging_memory_in_mb' and also a message saying 'Source is empty'. Presently the task is supposed to print the timestamp and is not dependent on any input.
TaskProcessor code:
#EnableBinding(Processor.class)
#EnableConfigurationProperties(TaskProcessorProperties.class)
public class TaskProcessor {
#Autowired
private TaskProcessorProperties processorProperties;
public TaskProcessor() {
}
#Transformer(inputChannel = Processor.INPUT, outputChannel = Processor.OUTPUT)
#ELI(level = "info", eventType = ELIEventType.INBOUND)
public Object setupRequest(String message) {
Map<String, String> properties = new HashMap<String, String>();
properties.put("payload", message);
TaskLaunchRequest request = new TaskLaunchRequest(processorProperties.getUri(), null, properties, null);
return new GenericMessage<>(request);
}
}
TaskSink code:
#SpringBootApplication
#EnableTaskLauncher
#EnableBinding(Sink.class)
#EnableConfigurationProperties(TaskSinkProperties.class)
public class FisIfxEventTaskSinkApplication {
public static void main(String[] args) {
SpringApplication.run(FisIfxEventTaskSinkApplication.class, args);
}
}
I provided the stream I am using earlier in the post. Sink is receiving the TaskLaunchRequest with uri and payload as you can see here and unable to launch the task.

Before I begin, you have a number of questions here. In the future, it's better to break them up into multiple questions so that they are easier to find by other users and easier to answer. That being said:
A little context on the current state of things
In order to understand how things will work, it's important to understand the current state of things. The current releases of the software involved are:
Pivotal Cloud Foundry (PCF) - 1.7.12. This version is required for any task support.
Spring Cloud Task (SCT) - 1.0.2.RELEASE
Spring Cloud Data Flow CF (SCDF) - 1.0.0.BUILD-SNAPSHOT (current as of the date of this post).
Currently PCF 1.7.12+ has all the capabilities to run tasks. You can create v3 applications (the type of application used to launch a task), run it as a task, etc. However, the tooling around that functionality is not currently complete. There is no support for v3 applications in Apps Manager or the CLI. There is a plugin for the CLI that is more of a dev tool that can be used to help with some functions (it will show you logs, etc), but it is not fully functional and requires a specific version of the CLI to work [1]. This is one of the reasons that the task functionality within PCF is still considered experimental.
Spring Cloud Task is currently GA and supports all the functionality needed to effectively run tasks on CF. However, it's important to note that SCT doesn't handle orchestration so the actual launching of tasks on CF is the responsibility of either the user, or Spring Cloud Data Flow (the easier route).
Spring Cloud Data Flow's Cloud Foundry server implementation currently has functionality to launch tasks on PCF in the latest snapshots. We have validated this against 1.7.12 as well as the development branch of 1.8.
The task workflow within SCDF
Tasks are fundamentally different from stream applications within the context of SCDF. When you create a stream definition, you are given the option to deploy it. What this does is it actually downloads the Spring Boot über jars and deploys them to PCF as long running processes. If they go down, PCF, will relaunch them as expected, etc.
Tasks on the other hand, are not deployed. They are launched. The difference is that while you create a task definition, there is nothing deployed until you click launch. And when the task completes, the software is shut down and cleaned up. So while a stream definition may have states, it's really a one to one relationship between the definition and the deployed software. Where with a task, you can launch a task definition as many times as you want.
Your issues
Reading through your post, I see a few things that you are struggling with. Let me see if I can help:
Task Definitions within SCDF and launching them via a stream - When launching a task from a stream, the task registry within SCDF is not used. The sink expects the URL for the resource to be within the TaskLauchRequest.
Apps Manager and tasks - As mentioned above, there is no support for v3 applications in Apps Manager yet so you won't be able to see your tasks there.
Viewing the logs - In order to debug what's going wrong with launching your task on CF, you're going to want to view the logs. To do so, use the v3 CLI plugin mentioned above to view them. It's important to note that you can only tail live logs with the plugin, not view logs that have previously been rendered. Because of that, when testing, you'll want to tail the logs as soon as the app is created, before it's launched.
Error in SCDF Shell - The error you received from the SCDF shell (CF-UnprocessableEntity(10008):...) leads me to wonder if you have both the correct version of PCF (1.7.12+) and the correct version of the following other libraries:
spring-cloud-deployer-cloudfoundry - The latest snapshots
cf-java-client - 2.0.0.M10+
reactor-core - 3.0.0.RC1+
I hope this helps!
[1] https://github.com/cloudfoundry/v3-cli-plugin
Task support is not available in 1.0.0.M4 release of SCDF's CF-server. In this release, the task commands/REST-APIs should be disabled - see here. And for that reason, you wouldn't see any docs related to Tasks in the 1.0.0.M4 reference guide.
That said, the Task support is available/enabled in the BUILD-SNAPSHOT release. If you're locally building the CF-server and upon pushing it to CF, you could take advantage the task commands in the shell to create and launch task definitions.
I can't understand whether there's something in sharepoint that that's causing
my web worker to throw an error as soon as its created In IE11 . The same worker runs great on chrome. Even tried a simple test:
the worker file :
self.addEventListener('message',function(e){ console.log("message"); })
and I'm creating the worker like so:
var worker = new Worker('http://{rootSite}/sites/53/Style%20Library/testworker.js')
worker.addEventListener('message',function(e){ console.log("message"); });
worker.addEventListener('error',function(e){ console.log("error"); });
It's strange because I tested the same script on a non sharepoint site and it worked on IE.
but on a sharepoint site as soon as create the test worker from the same site's doc library.. it throws an error.. with a null message !!
Please can anyone tell me what is going on here?!
Old question but I'd like to leave an answer for anyone who stumbles upon it.
Loading a Web worker via blob in IE has many limitations. Wouldn't recommend going down that route.
For some reason, Internet Explorer blocks Web workers from loading when the file is loaded from a sharepoint site.
Storing your Web worker files in the _layouts folder works well.
Okay ... So for all the share point developers who ever want to use web workers in their apps..
I still don't know why in internet explorer the web worker failed to load the external script
But apparently an inline web worker works !
So you could store you worker code in the doc library as a text file. And then get its content via ajax and then create an inline worker. You will need the window.URL object and the blob constructor :
First build a blob from the javascript code as a string:
Var string = "worker code ";
Var blob = new blob([ string] , {type:"text/javascript"});
Var worker = new Worker(URL.createUriObject(blob));
I have a Ruby on Rails 4.0 and PostgreSQL app hosted in an Ubuntu VPS. in this application I want to send email based on data in the database. for example a background job check a table content per hour and depend on content send email to user or not. I decided to do this work by Resque.
how can I do that?
should I do in Rails app or in an independent service?
and how can I schedule this job?
There are couple of more options I advise you to try to
1. Cron : One of most preferred approach for any unix developer to run a task based upon some interval . here are read more about
FYI: if you facing problem with understanding cron settings there are gem available to do the same for you its called whenever
2. Resque-Scheduler : Surely you missed one of Resque plugins that provide exactly the same feature that you need its called resque-scheduler . It too provide cron like settings for you to work on
Please check the above link for more info
Hope this helps.
I do not use Resque because I want a process in the Ubuntu server that in a schedule time (per hour). for example per hour check the table content and send alarm to the users by email.
I make a process by Daemon and rufus-scheduler for scheduling.
Process.daemon(true)
task_test = TaskTest.new
pid = Process.fork do
task_test.task
end
class TaskTest
def task
scheduler = Rufus::Scheduler.new
scheduler.every '1h' do
msg = "Message"
mailer = MailerProcess.new
mailer.send_mail('email-address', 'password', 'to-email', 'Subject', msg)
puts Time.now
end
scheduler.join
end
end
