I'm new to jade and I have 5 agents in eclipse that have formula for finding an average and the question is how to send information from agent to this formula for calculation?
I'll be glad if someone can help me with this.
For example, there is one of my agents. There's no formula, because I don't know how to represent it. This is math expression of it: n+=alfa(y(1,2)-y(1,1))
public class FirstAgent extends Agent {
private Logger myLogger = Logger.getMyLogger(getClass().getName());
public class WaitInfoAndReplyBehaviour extends CyclicBehaviour {
public WaitInfoAndReplyBehaviour(Agent a) {
super(a);
}
public void action() {
ACLMessage msg = myAgent.receive();
if(msg != null){
ACLMessage reply = msg.createReply();
if(msg.getPerformative()== ACLMessage.REQUEST){
String content = msg.getContent();
if ((content != null) && (content.indexOf("What is your number?") != -1)){
myLogger.log(Logger.INFO, "Agent "+getLocalName()+" - Received Info Request from "+msg.getSender().getLocalName());
reply.setPerformative(ACLMessage.INFORM);
try {
reply.setContentObject(7);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
else{
myLogger.log(Logger.INFO, "Agent "+getLocalName()+" - Unexpected request ["+content+"] received from "+msg.getSender().getLocalName());
reply.setPerformative(ACLMessage.REFUSE);
reply.setContent("( UnexpectedContent ("+content+"))");
}
}
else {
myLogger.log(Logger.INFO, "Agent "+getLocalName()+" - Unexpected message ["+ACLMessage.getPerformative(msg.getPerformative())+"] received from "+msg.getSender().getLocalName());
reply.setPerformative(ACLMessage.NOT_UNDERSTOOD);
reply.setContent("( (Unexpected-act "+ACLMessage.getPerformative(msg.getPerformative())+") )");
}
send(reply);
}
else {
block();
}
}
}
So from what I can make out you want to (1) send a formula/task to multiple platforms, (2) have them performed locally, (3) and have the results communicated back.
I think there are atleast two ways of doing this:
The first is sending an object in an ACLMessage using Java Serialisation. This is a more OOP approach and not very "Agenty".
The second being the cloning or creating a local task agent.
Using Java SerialZation. (Solution 1)
Create an object for the calculation
class CalculationTask implements serialization
{ int n;
int calculate(){
n+=alfa(y(1,2)-y(1,1));
}
}
send the calculation object via ACLMESSAGE from the senderAgent.
request.setContentObject(new CalculationTask())
recieve the calculation object by recieverAgent and perform calculation on the object. Then response setting the complete task in the response.
CalculationTask myTask = request.getContentObject();
myTask.calculate();
ACLMESSAGE response = request.createReply();
response.setContentObject(myTask());
response.setPerformative(ACLMESSAGE.INFORM)
send(response)
The senderAgent then receives the complete job.
ACLMESSAGE inform = getMessage();
CalculationTask completeTask = inform.getContentObject();
completeTask.process()
Creating local Task Agents (Solution 2)
The Agent Orientated way of doing it would be to launch a task agent on each platform. Have each task agent complete the task and respond appropriately.

Our web app allows the end-user to set the queue of recurring jobs on the UI. (We create a queue for each server (use server name) and allow users to choose server to run)
How the job is registered:
RecurringJob.AddOrUpdate<IMyTestJob>(input.Id, x => x.Run(), input.Cron, TimeZoneInfo.Local, input.QueueName);
It worked properly, but sometimes we check the log on Production and found that it runs on the wrong queue (server). We don't have more access to Production so that we try to reproduce at Development but it's not happened.
To temporarily fix this issue, we need to get the queue name when the job running, then compare it with the current server name and stop it when they are diferent.
Is it possible and how to get it from PerformContext?
Noted: We use HangFire version: 1.7.9 and ASP.NET Core 3.1
You may have a look at https://github.com/HangfireIO/Hangfire/pull/502
A dedicated filter intercepts the queue changes and restores the original queue.
I guess you can just stop the execution in a very similar filter, or set a parameter to cleanly stop execution during the IElectStateFilter.OnStateElection phase by changing the CandidateState to FailedState
Maybe your problem comes from an already existing filter which messes up with the queues.
Here is the code from the link above :
public class PreserveOriginalQueueAttribute : JobFilterAttribute, IApplyStateFilter
{
public void OnStateApplied(ApplyStateContext context, IWriteOnlyTransaction transaction)
{
var enqueuedState = context.NewState as EnqueuedState;
// Activating only when enqueueing a background job
if (enqueuedState != null)
{
// Checking if an original queue is already set
var originalQueue = JobHelper.FromJson<string>(context.Connection.GetJobParameter(
context.BackgroundJob.Id,
"OriginalQueue"));
if (originalQueue != null)
{
// Override any other queue value that is currently set (by other filters, for example)
enqueuedState.Queue = originalQueue;
}
else
{
// Queueing for the first time, we should set the original queue
context.Connection.SetJobParameter(
context.BackgroundJob.Id,
"OriginalQueue",
JobHelper.ToJson(enqueuedState.Queue));
}
}
}
public void OnStateUnapplied(ApplyStateContext context, IWriteOnlyTransaction transaction)
{
}
}
I have found the simple solution: since we have known the Recurring Job Id, we can get its information from JobStorage and compare it with the current queue (current server name):
public bool IsCorrectQueue()
{
List<RecurringJobDto> recurringJobs = Hangfire.JobStorage.Current.GetConnection().GetRecurringJobs();
var myJob = recurringJobs.FirstOrDefault(x => x.Id.Equals("My job Id"));
var definedQueue = myJob.Queue;
var currentServerQueue = string.Concat(Environment.MachineName.ToLowerInvariant().Where(char.IsLetterOrDigit));
return definedQueue == "default" || definedQueue == currentServerQueue;
}
Then check it inside the job:
public async Task Run()
{
//Check correct queue
if (!IsCorrectQueue())
{
Logger.Error("Wrong queue detected");
return;
}
//Job logic
}
I am trying to learn unit testing with Akka.
I have a situation where one of my tests was throwing an exception on construction and was wondering what the best way to capture this and log or otherwise throw it would be. As it stands now I had to attach a debugger and see where it threw.
I thought that I could perhaps create another actor which does logging and, on error, have a message sent to it. Breakpoints I put in the ErrorActor were never hit though. It seems as though the RootActor failed and timed out before the message was sent / received.
Is there something I'm doing wrong here or am I fundamentally off base with this? What is the the recommended way to catch errors in unit tests?
Thanks very much
[Fact]
public void CreateRootActor()
{
// Arrange
var props = Props.Create(() => new RootActor());
Sys.ActorOf(Props.Create( () =>new TestErrorActor(TestLogger)), ActorPaths.ErrorActor.Name); // register my test actor
// Act
var actor = new TestActorRef<RootActor>(this.Sys, props);
// Assert
Assert.IsType<RootActor>(actor.UnderlyingActor);
}
public class RootActor : ReceiveActor
{
private ITenantRepository tenantRepository;
public RootActor(ILifetimeScope lifetimeScope)
{
try
{
this.tenantRepository = lifetimeScope.Resolve<ITenantRepository>(); // this throws
}
catch (Exception e)
{
Context.ActorSelection(ErrorActor.Name).Tell(new TestErrorActor.RaiseError(e));
throw;
}
....
I got around this by using Akka.Logger.Serilog and a try / catch in the RootActor. I deleted the ErrorActor.
I have some parameterized tests
#ParameterizedTest
#CsvFileSource(resources = "testData.csv", numLinesToSkip = 1)
public void testExample(String parameter, String anotherParameter) {
// testing here
}
In case one execution fails, I want to ignore all following executions.
AFAIK there is no built-in mechanism to do this. The following does work, but is a bit hackish:
#TestInstance(Lifecycle.PER_CLASS)
class Test {
boolean skipRemaining = false;
#ParameterizedTest
#CsvFileSource(resources = "testData.csv", numLinesToSkip = 1)
void test(String parameter, String anotherParameter) {
Assumptions.assumeFalse(skipRemaining);
try {
// testing here
} catch (AssertionError e) {
skipRemaining = true;
throw e;
}
}
}
In contrast to a failed assertion, which marks a test as failed, an assumption results in an abort of a test. In addition, the lifecycle is switched from per method to per class:
When using this mode, a new test instance will be created once per test class. Thus, if your test methods rely on state stored in instance variables, you may need to reset that state in #BeforeEach or #AfterEach methods.
Depending on how often you need that feature, I would rather go with a custom extension.
I'm currently working on a Petrel plug-in in which I need to run a simulation case (through a "For Loop"), I create my case runner, export it and the run it...but after finishing the simulation and closing the console, I check the CaseRunner.IsRunning property and it shows true! This cause that the results have not been loaded to the petrel system.
I tried to load the results manually after finishing the Run of my case (using caserunner and also using a batch file in my code) and I can't see any results in the programming environment.
Does anybody have a solution for this situation?
This is the related part of my code:
Case theCase = arguments.TheCase;
Case Test2 = simroots.CreateCase(theCase, "FinalCase");
CaseRunner cRunners = SimulationSystem.GetCaseRunner(Test2);
cRunners.Export();
cRunners.Run();
bool b = cRunners.IsRunning;
actually I checked when the process finishes; after "cRunners.Run" the code waits for exit the process using:
System.Diagnostics.Process[] parray = System.Diagnostics.Process.GetProcesses();
foreach (System.Diagnostics.Process pr in parray)
{
if (pr.ProcessName == "cmd")
{
pr.WaitForExit();//just wait
}
}
and when the console closes itself, i checked the cRunners.IsRunning term.
However, I'm not so expert... can you show me an example of using CaseRunnerMonitor? both definition of the derived class and its implementation.
All I need is running a simulation case n times via a for loop and
after each Run access to its provided summary results.
I tried some different scenarios to get my desired results, I put here some of them
First I create my CaseRunnerMonitor class:
public class MyMonitor : CaseRunnerMonitor
{
//…
public override void RunCompleted()
{
// define arguments
foreach (Slb.Ocean.Petrel.DomainObject.Simulation.SummaryResult sr in simroot.SummaryResults)
{
IEnumerable ….
List ….
// some codes to change the input arguments according to the current step simulation summary results
}
PetrelLogger.InfoOutputWindow("MyMonitor is completed!");
}
//…
}
And then use it:
private void button1_Click(object sender, EventArgs e)
{
// Some codes that define some arguments…
for (int j = 0; j < 8; j++)
{
// some changes in the arguments
Case MyTest;
MyMonitor monit4 = new MyMonitor();
SimulationRoot simroot = SimulationRoot.Get(PetrelProject.PrimaryProject);
using (ITransaction trans = DataManager.NewTransaction())
{
trans.Lock(simroot);
MyTest = simroot.CreateCase(OriginalCase, MycaseNameFunc());
trans.Commit();
}
CaseRunner cRun = SimulationSystem.GetCaseRunner(MyTest);
cRun.Export();
cRun.Run(monit4);
//Wait(); //waits for current process to close
}
}
But the thing is that MyTest case results part are empty after my run is completed. in this case all the results loaded to the petrel when the 8th (last) simulation completes. If I don’t activate the Wait() function, all 8 runs are almost calling simultaneously…
I changed my scenario, my callback after each run is read the simulation results, change something and call next run so
I create my CaseRunnerMonitor class:
public class MyMonitor2 : CaseRunnerMonitor
{
//…
public override void RunCompleted()
{
// define arguments
index++;
if (index <=8)
{
foreach (Slb.Ocean.Petrel.DomainObject.Simulation.SummaryResult sr in simroot.SummaryResults)
{
IEnumerable ….
List ….
// some codes to change the input arguments according to the current step simulation summary results
}
Case MyTest;
MyMonitor monit4 = new MyMonitor();
SimulationRoot simroot = SimulationRoot.Get(PetrelProject.PrimaryProject);
using (ITransaction trans = DataManager.NewTransaction())
{
trans.Lock(simroot);
MyTest = simroot.CreateCase(OriginalCase, MycaseNameFunc());
trans.Commit();
}
CaseRunner cRun = SimulationSystem.GetCaseRunner(MyTest);
cRun.Export();
cRun.Run(monit4);
}
PetrelLogger.InfoOutputWindow("MyMonitor2 is completed!");
}
//…
}
And then use it:
private void button1_Click(object sender, EventArgs e)
{
Index=0;
// Some codes that define some arguments…
// some changes in the arguments
Case MyTest;
MyMonitor monit5 = new MyMonitor();
SimulationRoot simroot = SimulationRoot.Get(PetrelProject.PrimaryProject);
using (ITransaction trans = DataManager.NewTransaction())
{
trans.Lock(simroot);
MyTest = simroot.CreateCase(OriginalCase, MycaseNameFunc());
trans.Commit();
}
CaseRunner cRun = SimulationSystem.GetCaseRunner(MyTest);
cRun.Export();
cRun.Run(monit5);
}
in this situation no need to wait() function is required. But the problem is that I access to MyTest case results in one level before the current run completes. i.e, I can view the step 5 results via MyTest.Results when the run 6 is completed while step 6 results are empty despite of completion of its run.
I check the CaseRunner.IsRunning property and it shows true
This is because Caserunner.Run() is non-blocking; that is, it starts another thread to launch the run. Control flow then passes immediately to your cRunners.IsRunning check which is true as simulation is in progress.
cRunners.Run(); //non-blocking
bool b = cRunners.IsRunning;
You should look at CaseRunnerMonitor if you want a call-back when the simulation is complete.
Edit:
can you show me an example of using CaseRunnerMonitor? both definition of the derived class and its implementation.
Create your monitor class:
public class CustomCaseRunnerMonitor : CaseRunnerMonitor
{
//...
public override void RunCompleted()
{
//This is probably the callback you want
}
}
Use it:
Case myCase = WellKnownSimulators.ECLIPSE100.CreateSimulationCase(...);
CaseRunner runner = SimulationSystem.GetCaseRunner(myCase);
var myMonitor = new CustomCaseRunnerMonitor(...);
runner.Run(myMonitor);
//Your callbacks defined in your CustomCaseRunnerMonitor will now be called
See also "Running and monitoring a Simulation" in SimulationSystem API documentation.
Ah, OK. I didn't realise you were trying to load results with the CaseMonitor.
I'm afraid the short answer is "No, you can't know when Petrel has loaded results".
The long answer is Petrel will automatically load results if the option is set in the Case arguments. (Define Simulation Case -> Advance -> Automatically load results).
In API:
EclipseFormatSimulator.Arguments args = EclipseFormatSimulator.GetEclipseFormatSimulatorArguments(myCase);
EclipseFormatSimulator.Arguments.RuntimeArguments runtimeArgs = args.Runtime;
runtimeArgs.AutoLoadResults = true;
runtimeArgs.AutoLoadResultsInterval = 120; //How frequently in seconds Petrel polls sim dir.
You will have to poll SimulationRoot.SummaryResults (using the same API you are already using) after case has finished.
You should use the CaseRunnerMonitor we discussed to determine when to start doing this, rather than the System.Diagnostics.Process[] parray = System.Diagnostics.Process.GetProcesses(); code you currently have.
I'm struggling with making a call transfer in a UMCA IVR app I've built. This is not using Lync.
Essentially, I have an established call from an outside user and as part of the IVR application, they select an option to be transferred. This transfer is to a configured outside number (ie: Our Live Operator). What I want to do is transfer the original caller to the outside number, and if a valid transfer is established, I want to terminate the original call. If the transfer isn't established, I want to send control back to the IVR application to handle this gracefully.
My problem is my EndTransferCall doesn't get hit when the transfer is established. I would have expected it to hit, set my AutoResetEvent and return a True, and then in my application I can disconnect the original call. Can somebody tell me what I'm missing here?
_call is an established AudioVideoCall. My application calls the Transfer method
private AutoResetEvent _waitForTransferComplete = new AutoResetEvent(false);
public override bool Transfer(string number, int retries = 3)
{
var success = false;
var attempt = 0;
CallTransferOptions transferOptions = new CallTransferOptions(CallTransferType.Attended);
while ((attempt < retries) && (success == false))
{
try
{
attempt++;
_call.BeginTransfer(number, transferOptions, EndTransferCall, null);
// Wait for the transfer to complete
_waitForTransferComplete.WaitOne();
success = true;
}
catch (Exception)
{
//TODO: Log that the transfer failed
//TODO: Find out what exceptions get thrown and catch the specific ones
}
}
return success;
}
private void EndTransferCall(IAsyncResult ar)
{
try
{
_call.EndTransfer(ar);
}
catch (OperationFailureException opFailEx)
{
Console.WriteLine(opFailEx.ToString());
}
catch (RealTimeException realTimeEx)
{
Console.WriteLine(realTimeEx.ToString());
}
finally
{
_waitForTransferComplete.Set();
}
}
Is the behavior the same if you don't use the _waitForTransferComplete object? You shouldn't need it - it should be fine that the method ends, the event will still be raised. If you're forcing synchronous behavoir in order to fit in with the rest of the application though, try it like this:
_call.EndTransfer(
_call.BeginTransfer (number,transferOptions,null,null)
);
I'm just wondering if the waiting like that causes a problem if running on a single thread or something...
