Team,
My biztalk send port instance gets hung and stays in the active state for longer periods of time. I would like to monitor that send port active instance with the help of C#.
I intend to run a code which will check if the send port(passed as a parameter) is still in a running state or not. Can anyone help me with that piece of code ?
Use WMI MSBTS_ServiceInstance.ServiceStatus Property:
public static int GetRunningServiceInstanceCount()
{
int countofServiceInstances = 0;
try
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\MicrosoftBizTalkServer", "SELECT * FROM MSBTS_ServiceInstance WHERE ServiceStatus = 1 or ServiceStatus = 2");
countofServiceInstances = searcher.Get().Count;
return countofServiceInstances;
}
catch (ManagementException exWmi)
{
throw new System.Exception("An error occurred while querying for WMI data: " + exWmi.Message);
}
}
To get to your actual problem: The SFTP adapter in BizTalk 2016 has a great way of using the most recent version of the FTP code. This might solve stability issues.
Assuming from your BizTalk 2013 tag, you're probably not using the 2016 version, in that case double check you are at least at CU3 since that one solves a few critical SFTP bugs.

I recently created a proof of concept console application using SignalR (self host). It worked a treat for our use. The client connected fine and I was able to send updates from the server to the client. Lovely!
I've now transferred the code from the Console application to a winforms application for a prettier UI. Now that same client won't connect to the server yet it will still connect to the old Console version.
Winforms code:
string url = "http://localhost:8080";
using (WebApp.Start(url))
{
// Let the app know the server is up
}
Console code:
string url = "http://localhost:8080";
using (WebApp.Start(url))
{
Console.WriteLine("Server running on {0}", url);
Console.ReadLine();
}
Client connection code:
if (!connected)
{
int i = 0;
// Try 3 times
while (i <= 2)
{
try
{
string server = Properties.Settings.Default.Server + ":" + Properties.Settings.Default.PortNumber.ToString();
connection = new HubConnection(server);
connection.StateChanged += connection_StateChanged;
hub = connection.CreateHubProxy("MyHub");
connection.Start().Wait();
hub.On<string>("addMessage", param => { UpdateAlarmStatus(param); });
return true;
}
catch (Exception)
{
i++;
}
}
return false;
}
else
{
return true;
}
The error the client is reporting is:
Exception:Thrown: "No connection could be made because the target machine actively refused it" (System.Net.Sockets.SocketException)
A System.Net.Sockets.SocketException was thrown: "No connection could be made because the target machine actively refused it"
Time: 25/01/2015 15:09:23
Thread:Worker Thread[8232]
Why would the target machine (localhost) refuse itself which the Console version doesn't? I've been looking at the code over and over and I cannot see where I'm going wrong. Can anyone point me in the right direction please?
Thank you for reading.
Paul.
I suspect this is an issue with the configuration of your machine/infrastructure rather than the code itself, which looks fine at first glance.
Have you checked the console debug output in Visual Studio? I recently encountered an issue with similar symptoms and that was what gave me the initial clue to keep investigating. In my particular case, an exception was written to the console debug output that didn't make it to the client.
SignalR will normally negotiate with the server automatically to determine the best transport method to use. In a .NET client, the available options are LongPollingTransport, ServerSentEventsTransport and WebSocketTransport. So for some reason, your console app can use at least one of those methods, whereas your WinForms client cannot.
You can perhaps enable tracing to give you more information to work with. To do this, enter the below before you create the hub proxy:
hubConnection.TraceLevel = TraceLevels.All;
hubConnection.TraceWriter = Console.Out;
ASP.NET doco on SignalR tracing
I'm currently developping a failover service for an environment using Dynamics AX and 2 mirrored SQL servers, and I have some issues getting AX to work the way I expect it to.
I have developped a service which does the following :
- try to connect to the SQL servers instances
- start Dynamics AX using the reachable SQL server.
To do this, I have created 2 AX configuration files (.axc), each one pointing to a SQL server.
But when I try to start the service, no mater which way I use, AX always start using the configuration that is set using the AX server configuration tool.
Here are the command I've tried to start the AX service :
sc start AOS60$01 -regConfig=Config1
net start AOS60$01 /"-regConfig=Config1"
The service always start successfully, but doesn't care about the regConfig parameter.
As anybody an idea about how to solve this issue?
Regards,
Thomas T.
After looking for a while after a way to start the service with the -regConfig parameter, I finally gave up and developped a method which directly edit the Registry key holding the startup configuration value.
private void UpdateRegistry(string parameter)
{
RegistryKey key = Registry.LocalMachine.OpenSubKey("SYSTEM\\CurrentControlSet\\services\\Dynamics Server\\6.0\\01", true);
key.SetValue("Current", parameter, RegistryValueKind.String);
key.Close();
}
public void StartLocalServiceWithCLI(string serviceToStart, string parameter)
{
try
{
UpdateRegistry(parameter);
Process process = new System.Diagnostics.Process();
ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = string.Format("/C sc start {0} ", serviceToStart);
process.StartInfo = startInfo;
process.Start();
logger.WriteInfo(string.Format("Process {0} starting, parameters [{1}]", serviceToStart, parameter));
}
catch (Exception e)
{
logger.WriteError(string.Format("Error starting process {0}, parameters [{1}]\nError details :{2}", serviceToStart, parameter, e.Message));
}
}
I am trying to use elastic search with java api, but when i try to run application, i am getting following exception.

can any one kindly help me, i am new to elastic search and have no idea how to resolve the issue.
I am using this code to connect to my elasticsearch and its pretty well working.

.put("cluster.name", clusterName).build();
this.client = new TransportClient(settings)
.addTransportAddress(new InetSocketTransportAddress(ipAddress,9300));
Where ipAddress and Clustername are argument of my function.
You should have a look at the network on your laptop. Check if you can connect to localhost. Another thing you could try is start two elasticsearch instances with the same configuration to see if they connect. Finally have a look at the network part of elasticsearch.yml. When having network problems on a local machine I usually try the following two options:
network.host: localhost
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicast.hosts: ["localhost"]
I think Elastic search server is Not started.. Try to hit in browser or curl comments.. If it works.. Try the above code..
NOTE:IF YOUR JAVA API JAR VERSION DIFFERS ALSO LL RAISE PROB.. ( get java api version same as ES version
Note : elasticsearch java api helps you connect to with elasticsearch.. But its can't start a elasticsearch node using api..
Your code is good.. It's Vry standard too..
I am developing a vehicle tracking system which uses GPS/GPRS/GSM. The tracking device I am currently using is GV100, a GPS/GPRS/GSM tracker from Quectel ([www.quectel.com][1].)
I am not able to establish connection between the device and the backend server. My question particularly is:
How do I send commands (AT Commands) to the device from the server?
How do I accept the response (reports and acknowledgement messages) from the device to save it in the database?
I sent command to the device with the MGV100 Manage Tool (Software provided by Quectel) via serial port. And I got acknowledgement SMS message on GSM enabled mobile telephone. Now, I want to send message from the server and accept reply on the server (not by SMS). I don’t know how to send command and receive the reply. I have no previous experience in developing such systems.
It would be great if I can get a sample code and setup procedures if it requires.
Where can I get a relevant tutorial for the case I mentioned?
Thanks jhonkola
To understand how server receives and send data to the device, I decided to first implement the communication between the client (currently my PC) and server. Though my ultimate goal is communicating with the device, currently I am trying to establish connection from my PC to the server. If I succeed in this, I will strive to communicate to server from the device which needs IP address and port number of server to send and receive data.
This is my assumption how to do it:
I can open a port on the server from .cs code so as to communicate
using TCP/UDP.
Client then can send and receive data via this
port.
I can save the data sent from the client on server's file
system and review it any time. (Am not storing the data in relational database because I don't want to bother about database issues now.)
This is how I tried to implement:
Server a C# Web Application:
When a button is clicked it opens a port and listens to client
protected void btnConnect_Click(object sender, EventArgs e)
{
try
{
continueListening = true;
while (continueListening)
{
int port=Int32.Parse(txtPort.Text);
lblOutput.Text = "Port is now " + port +". Waiting for connection";
TcpListener myList = new TcpListener(IPAddress.Parse(txtIpAddress.Text), port);
myList.Start();
Socket s = myList.AcceptSocket();
lblOutput.Text="Connection accepted from " + s.RemoteEndPoint;
byte[] b = new byte[100];
int k = s.Receive(b);
lblOutput.Text = ("Recieved...");
String obtainedText = "";
for (int i = 0; i < k; i++)
{
obtainedText = obtainedText + " " + (Convert.ToChar(b[i]));
}
writeToTextFile("C:/Users/MekAtIbex/Desktop/TESTED/RECIEVED.txt", obtainedText);
lblOutput.Text = obtainedText;
ASCIIEncoding asen = new ASCIIEncoding();
lblOutput.Text = lblOutput.Text +" "+ ("The string was recieved by the server.");
lblOutput.Text = lblOutput.Text +" "+ ("\r\nSent Acknowledgement");
}
Client: C# Windows application
private void btnSend_Click(object sender, EventArgs e)
{
try
{
TcpClient tcpClient = new TcpClient();
int port=Int32.Parse(txtPort.Text.Trim());
tcpClient.Connect(txtIpAddress.Text, port);
lblStatus.Text = ("Connected");
Stream stm = tcpClient.GetStream();
ASCIIEncoding asen = new ASCIIEncoding();
byte[] bytesToSend = asen.GetBytes(txtData.Text);
lblStatus.Text = ("Transmitting.....");
stm.Write(bytesToSend, 0, bytesToSend.Length);
byte[] bb = new byte[100];
int k = stm.Read(bb, 0, 100);
for (int i = 0; i < k; i++)
{
txtaResponse.Text = txtaResponse.Text + "\n" + "Res... " + new DateTime() + " " + Convert.ToChar(bb[i]);
Console.Write(Convert.ToChar(bb[i]));
}
tcpClient.Close();
}
catch (Exception ex)
{
lblStatus.Text = ("Connected");
txtaRequest.Text = txtaRequest.Text + "\n" + "Err... " + new DateTime() + " " + ex.StackTrace;
}
}
My current questions are:
Is my assumption correct? If not how should I do it?
I have tried to save it using the above code but I didn't got the file.
What is the advantage and disadvantage of using UDP in comparison TCP for tracking applications?
I have browsed well, but I couldn't find a place for a good start. And, as I have no experience in such applications, I couldn't debug my application.
My current questions are:
Is my assumption correct? If not how should I do it?
Yes, your basic assumptions are correct. The server would open a listening port and then the client could connect to this port and drop off data as needed. You can have the server log this to a file for later review too.
I have tried to save it using the above code but I didn't got the
file.
Is the file already created? The method you have will fail if the file is not existent on the system.
What is the advantage and disadvantage of using UDP in comparison TCP
for tracking applications?
UPD is less expensive in terms of network setup. It is the "fast and dirty" method of communication. The downside is that you may not get every message properly delivered. In some applications, this just doesn't matter and the benefits are worth this cost.
Now a few things I'd change:
Change IPAddress.Parse(txtIpAddress.Text) to IPAddress.Any
This will allow your listener the broadest ability to catch incoming messages and will most likely not effect other systems (since this is essentially your first networking program).
You'll also want to make your listener spawn a thread to handle the file writing and then go back to listening. This is a very standard practice and allows for servers to handle multiple connections.
It is difficult to comprehensively answer this, as a good answer would require detailed knowledge about the product. I suggest that you contact the manufacturer / reseller for support.
A few general points:
Sending commands over network to the device requires that you are able to connect to the device from internet. This is not always easy over GSM network, as the operators may block all incoming traffic. The manufacturer may have provided solutions for this.
If you can connect to the device, the protocol that is used to give commands (assuming that such protocol is built-in) will also contain a mechanism to receive any responses.
Am facing a problem, while creating components through TOM API using .NET/COM Interop.
Actual Issue:
I have 550 components to be created through custom page. I am able to create between 400 - 470 components but after that it is getting failed and through an error message saying that
Error: Thread was being aborted.
Any idea / suggestion, why it is getting failed?
OR
Is there any restriction on Tridion 2009?
UPDATE 1:
As per #user978511 request, below is error on Application event log:-
Event code: 3001
Event message: The request has been aborted.
...
...
Process information:
Process ID: 1016
Process name: w3wp.exe
Account name: NT AUTHORITY\NETWORK SERVICE
Exception information:
Exception type: HttpException
Exception message: Request timed out.
...

...
UPDATE 2:
#Chris: This is my common function, which is called in a loop by passing list of params. Here am using Interop dll's.
public static bool CreateFareComponent(.... list of params ...)
{
TDSE mTDSE = null;
Folder mFolder = null;
Component mComponent = null;
bool flag = false;
try
{
mTDSE = TDSEInitialize();
mComponent = (Component)mTDSE.GetNewObject(ItemType.ItemTypeComponent, folderID, null);
mComponent.Schema = (Schema)mTDSE.GetObject(constants.SCHEMA_ID, EnumOpenMode.OpenModeView, null, XMLReadFilter.XMLReadAll);
mComponent.Title = compTitle;
...
...
...
...
mComponent.Save(true);
flag = true;
}
catch (Exception ex)
{
CustomLogger.Error(String.Format("Logged User: {0} \r\n Error: {1}", GetRemoteUser(), ex.Message));
}
return flag;
}
Thanks in advance.
Sounds like a timeout, most likely in IIS which is hosting your custom page.
Are you creating them all in one synchronous request? Because that is indeed likely to time out.
You could instead create them in batches - or make sure your operations are done asynchronously and then polling the status regularly.
The easiest would just be to only create say 10 Components in one request, wait for it to finish, and then create another 10 (perhaps with a nice progress bar? :))
How you call TDSE object. I would like to mention here "Marshal.ReleaseComObject" procedure. Without releasing COMs objects can lead to enormous memory leaks.
Here is code for component creating:
private Component NewComponent(string componentName, string publicationID, string parentID, string schemaID)
{
Publication publication = (Publication)mTdse.GetObject(publicationID, EnumOpenMode.OpenModeView, null, XMLReadFilter.XMLReadContext);
Folder folder = (Folder)mTdse.GetObject(parentID, EnumOpenMode.OpenModeView, null, XMLReadFilter.XMLReadContext);
Schema schema = (Schema)mTdse.GetObject(schemaID, EnumOpenMode.OpenModeView, publicationID, XMLReadFilter.XMLReadContext);
Component component = (Component)mTdse.GetNewObject(ItemType.ItemTypeComponent, folder, publication);
component.Title = componentName;
component.Schema = schema;
return component;
}
After that please not forget to release mTdse ( in my case it is previously created TDSE object). Disposing "Components" object can be useful also after finish working with them.
For large Tridion batch operations I always use a Console Application and run it directly on the server.
Use Console.WriteLine to write to the output window and Console.ReadLine as the last line of code in the app (so the window stays open). I also use Log4Net as the logger.
This is by far the best approach if you have access to a remote session on the server - or can ask an admin to run it for you and give you access to the log folder via a network share.
As per #chris suggestions and part of immediate fix I have changed my web.config execution time out to 8000 seconds.
<httpRuntime executionTimeout="8000"/>
With this change, custom page is able to handle as of now.
Any more best suggestion, please post it.
