I have a BizTalk orchestration with an expression. The expression has the following:
construct msg_mymessage { msg_mymessage = msgInputXML; }
msgInputXML and msg_mymessage use the same schema, same message type and both show up under the Messages in Orchestration view.
After the expression I have a Construct Message and in the Construct message I have a Transform that uses msg_mymessage as a source and some other message as a destination.
I'm getting the errors:
use of unconstructed message 'msg_mymessage'
'msg_mymessage':message has not been initialized in construct statement
I'm not sure why I get this error. What should I be looking for?
Make sure that you use an assignment shape (inside a construct message wrapper) when you create msg_mymessage. Then just copy the code in the expression shape (msg_mymessage = msgInputXML;)
http://msdn.microsoft.com/en-us/library/ee253499(v=bts.10).aspx
Do you need to do,
msg_mymessage = new System.Xml.XmlDocument();
My guess is that you didn't construct msg_mymessage in earlier shapes.
Check the blog article Constructing BizTalk 2004 XML Messages (In an Orchestration) - Choices which demonstrates several ways to construct a message in BizTalk .
In your constructed messages shape, you need to define the message type you are going to create. when you drop the shape, the drop down dialog will ask you what type of message you are constructing. You can select more than one. so if you happen to have a message checked that isnt being constructed in this shape, you will get this exact message also.

I am trying to use Serilog in my .Net Core API to log to SQL Server with the Serilog-Sinks-MSSqlServer sink. The standard Level column either writes out the full value (e.g. Information, Warning, Error) or a TinyInt enum value if you set the StoreAsEnum property to true as shown here. I cannot seem to find an easy way (like there is in Log4net and NLog) to format the output to write only the first character of the Level (e.g. I, W, E). I tried setting the DataLength property to 1 but that causes the log entry to not be written at all.
I have been able to accomplish my desired behavior with a custom enricher that takes the Level value from the standard column and then uses just the first character to write to a custom column while removing the standard Level column but that really seems like overkill when I feel like there may be a formatting mechanism somewhere that I just haven’t seen.
For Serilog.Sinks.MSSqlServer, it does not expose easy way to custom the Level value.
If you check MSSqlServerSink, you will see that it convert IEnumerable<LogEvent> events to _traits.eventTable by a private method, which means you could not override the method void FillDataTable(IEnumerable<LogEvent> events).
In addition, for MSSqlServerSinkTraits, it is internal, you could not inherit from it to implement your own MSSqlServerSinkTrait.
There is no much thing you could not if you want to override something from Serilog.Sinks.MSSqlServer.
For easiest way, you may consider forking the Serilog.Sinks.MSSqlServer, and change GetStandardColumnNameAndValue from below code
case StandardColumn.Level:
return new KeyValuePair<string, object>(columnOptions.Level.ColumnName, columnOptions.Level.StoreAsEnum ? (object)logEvent.Level : logEvent.Level.ToString());
to change logEvent.Level.ToString() to your expected value like logEvent.Level.ToString().Substring(0,1).
Then build the project and reference this project instead of Serilog.Sinks.MSSqlServer
In an orchestration I notice that if I right-click in a construct message shape and select "Insert Shape" then three options are enabled:
Transform
Message Assignment
Call Rules
I would like to use the Call Rules option, have the rule populate a newly constructed message. Unfortunately, when I select this, I get the message "A Construct statement can only contain Message Assignment and Transform shapes".
Does anyone know if it possible to have a message populated in a BRE rule?
It seems the construct shape isn’t required. I guess a copy of the message that’s passed into the rule gets created implicitly.
I have a requirement where I will be receiving a batch of records. I have to disassemble and insert the data into DB which I have completed. But I don't want any message to come out of the pipeline except the last custom made message.
I have extended FFDasm and called Disassembler(), then we have GetNext() which is returning every debatched message out and they are failing as there is subscribers. I want to send nothing out from GetNext() until Last message.
Please help if anyone have already implemented this requirement. Thanks!
If you want to send only one message on the GetNext, you have to call on Disassemble method to the base Disassemble and get all the messages (you can enqueue this messages to manage them on GetNext) as:
public new void Disassemble(IPipelineContext pContext, IBaseMessage pInMsg)
{
try
{
base.Disassemble(pContext, pInMsg);
IBaseMessage message = base.GetNext(pContext);
while (message != null)
{
// Only store one message
if (this.messagesCount == 0)
{
// _message is a Queue<IBaseMessage>
this._messages.Enqueue(message);
this.messagesCount++;
}
message = base.GetNext(pContext);
}
}
catch (Exception ex)
{
// Manage errors
}
Then on GetNext method, you have the queue and you can return whatever you want:
public new IBaseMessage GetNext(IPipelineContext pContext)
{
return _messages.Dequeue();
}
The recommended approach is to publish messages after disassemble stage to BizTalk message box db and use a db adapter to insert into database. Publishing messages to message box and using adapter will provide you more options on design/performance and will decouple your DB insert from receive logic. Also in future if you want to reuse the same message for something else, you would be able to do so.
Even then for any reason if you have to insert from pipeline component then do the following:
Please note, GetNext() method of IDisassembler interface is not invoked until Disassemble() method is complete. Based on this, you can use following approach assuming you have encapsulated FFDASM within your own custom component:
Insert all disassembled messages in disassemble method itself and enqueue only the last message to a Queue class variable. In GetNext() message then return the Dequeued message, when Queue is empty return null. You can optimize the DB insert by inserting multiple rows at a time and saving them in batches depending on volume. Please note this approach may encounter performance issues depending on the size of file and number of rows being inserted into db.
I am calling DBInsert SP from GetNext()
Oh...so...sorry to say, but you're doing it wrong and actually creating a bunch of problems doing this. :(
This is a very basic scenario to cover with BizTalk Server. All you need is:
A Pipeline Component to Promote BTS.InterchageID
A Sequential Convoy Orchestration Correlating on BTS.InterchangeID and using Ordered Delivery.
In the Orchestration, call the SP, transform to SOAP, call the SOAP endpoint, whatever you need.
As you process the Messages, check for BTS.LastInterchagneMessage, then perform your close out logic.
To be 100% clear, there are no practical 'performance' issues here. By guessing about 'performance' you've actually created the problem you were thinking to solve, and created a bunch of support issues for later on, sorry again. :( There is no reason to not use an Orchestration.
As noted, 25K records isn't a lot. Be sure to have the Receive Location and Orchestration in different Hosts.
In Flash/Flex, is it possible to capture the result of 'trace' in code?
So, for example, if one part of the code calls trace("foo"), I'd like to automatically capture the string "foo" and pass it to some other function.
Edit: I'm not interested in trying to use trace instead of a proper logging framework… I want to write a plugin for FlexUnit, so when a test fails it can say something like: "Test blah failed. Here is the output: ... traced text ...".
Edit 2: I only want to capture the results of trace. Or, in other words, even though my code uses a proper logging framework, I want to handle gracefully code that's still using trace for logging.
As far as I know it's impossible to do it externally, google brings up no results. Have you considered creating a variable for the output and then adding that to the log, eg:
var outputtext = "text";
trace(outputtext);
// log outputtext here
Disregard if it isn't feasible, but I can't think of any other way.
However you can do it internally, if it's just for development purposes: http://broadcast.artificialcolors.com/index.php?c=1&more=1&pb=1&tb=1&title=logging_flash_trace_output_to_a_text_fil
If you want to write traces to a log, you can just use the Debug version of Flash Player and tell it to log traces.
I have a Debug.write method that sends the passed messages over a LocalConnection which I use that instead of trace. My requirement is to be able to capture the debug statements even when the SWF is running out of the authoring environment, but you can use this method to capture the trace messages.
As far as I understood you don't want to use logging, which is of course the right way to do it.
So, you can simply create a Static class with method trace, and call this method from anywhere in the application, that's how you will get all traces to one place, then could do what ever you want with the trace string before printing it to console.
Another way is to create bubbling trace event and dispatch it whenever you want to trace message, then add listener to STAGE for it and catch all events...
Hope its help
I would suggest looking through the source for the swiz framework. They use the flex internal logLogger app-wide and use best practices in a good majority of their code.
My problem, simplified:
I have a dataGrid with a dataProvider "documents"
A column of the datagrid has a labelFunction that gets the project_id field of the document, and returns the project name, from a bindable variable "projects"
Now, I dispatch the events to download from the server the documents and the projects, but If the documents get downloaded before the projects, then the label function gives an error (no "projects" variable)
Therefore, I must serialize the commands being executed: the getDocuments command must execute only after the getProjects command.
In the real world, though, I have dozens of resources being downloaded, and those command are not always grouped together (so I can't for example execute the second command from the onSuccess() method of the first, because not always they must be executed together..)..
I need a simple solution.. I need an idea..
If I understand you correctly, you need to serialize the replies from the server. I have done that by using AsyncToken.
The approach: Before you call the remote function, add a "token" to it. For instance, an id. The reply from the server for that particular call will then include that token. That way you can keep several calls separate and create chains of remote calls.
It's quite cool actually:
service:RemoteObject;
// ..
var call:AsyncToken = service.theMethod.send();
call.myToken = "serialization id";
private function onResult(event:ResultEvent):void
{
// Fetch the serialization id and do something with it
var serId:String = event.token.myToken;
}
