#Business Process (BPL)

5

InterSystems Ensemble Business Process Language (BPL) is a language used to describe executable business processes within a standard XML document.

Documentation.

I have a process that I am trying to duplicate from SQL Integration Services (SSIS) into Ensemble so that the rest of my team can help support any issues that may happen.

This particular job creates multiple dictionary files, but for each one of the dictionary files it creates, it also creates a control file that tells the vendor what to process.

I have a business process.

if it has an error it dies, or if a have a catch all/fault handler the execution flow goes there.

However, I want another behavior.

If any error occurs I want the process to "Pause" (and alert me), so I can figure out what went wrong and resume from the last request.

Here's an example of how it could work:

  1. If an error is caught, call BO
  2. BO defers response
  3. BO sends alert
  4. Fix BP
  5. Manually resolve deferred response

I'm not set on the exact pause/resume mechanic but I hope it makes the general idea of what I want clear enough. Ideas?

Opening Files Within A BPL

I have two files that I ultimately need to combine. The first file contains data from a PO. The second file contains tracking information. What I thought about doing was create a BS that grabs the first file, loads it into a record map and transfers it to a BPL. Then, the BPL would open the second file where I would write code to load the file into a second record map and then insert the tracking information to the correct places in the first file based on PO line items.

Hello,

I want to add a couple of properties to a custom Transform class to give the user the ability to edit its properties directly in the Business Process visual editor. It can be easily done with other Production components, but I can't find in the documentation how to do the same with my Transform. Is it possible?

And another question is about how to use the 'aux' parameter of the DataTransform.Transform method if my component is non-visual?

What are the pros and cons of developing a custom database driven routing engine vs. using the Ensemble standard routing engine. What I'm trying to accomplish with the custom routing engine is less manual intervention every time a new route is added. The con I can see with the custom engine is performance may lag behind the standard engine. My development vs. Intersystems essentially.

I appreciate feedback. Thanks!

I am creating a BPL using the Management Portal instead of creating a custom class.

As per the documentations 'request object' contains properties those were in the original request message object or primary request and can be reference using the dot syntax.

So if the primary request was an HL7 message, i should be able to pull the value MSH:9.2 as follow

request.{MSH:9.2} and assign it to a context property

Oracle Transaction

Hi,

I have a question related with EnsLib.SQL.OutboundAdapter adapter.

Is there a way to open an oracle transaction and do either commit or rollback depending on the query result?

Is posible to keep open an oracle transaction to execute a lot of queries on different methods on the same business operation and do a commit when the business process finished?

Thanks and Best Regards

Query Response from MSSQL

I am having an intermittent issue that when I make a call to MSSQL from a BPL that the response does not come back in the amount of time required. Since the call from the BPL is synchronous I tried changing the timeout to 60 but it has not helped (see below). Is there anyway to guarantee that the call waits long enough for a response before continuing on?

Thanks

Hi All,

If I remember it correctly there is a functionality in IRIS to make this possible.

I've got two incoming Business Services of files from different sources.

BS1: An Ens.StreamContainer with some info and metadata which point to a specific file. Ens.StreamContainer will be send to a BP.

BS2: The files where the metadata points to. It's in the Ens.StreamContainer

But dependent on the flow the file could be later available on BS2. So I want the BPL to wait for the file to arrive at BS2.

Hi all,

We're in the process of creating several courses for creating custom business components for productions. This includes custom business operations, BPL processes, and custom business services. Custom Business Operations and Custom Business Services are both aimed at software developers while BPL processes can be also be created by business analysts. What are some gotchas or best practices you've learned that you wish you knew when first building these components?

We'd love to include what you've learned into these courses so others can learn from them as well!

Is it possible to dynamically adjust the RetryInterval andFailureTimeout settings in a BPL?

I've got a business process that calls a web service operation to get a session ID from an external system. There is a string property returned in the body of the response that indicate an exception occurred in the external system. I have code in the BPL that examines the property and sets the status property to an error status when that occurs.

SQLCODE Error -400

I have a code block in a BPL. I have the below SQL and code. All variables have been declared and set. When I run the SQL, if there are no values returned, I get 100 for the value of SQLCODE when I perform the FETCH, which is correct. If values are returned, I get a -400 error when I perform the first FETCH. I've investigated, but cannot find the reason for a -400 error. Hoping someone out here understands this and knows what's wrong.

I have a production that takes in an HL7 message thru a business service. The business service passes the incoming HL7 message to a business process that calls a transform to transform the HL7 message to a message class. After the transform is finished, the business process uses a code block to pass the object created by the transform to a method class that processes the data in the object. What would be the correct syntax for passing in the object to the class method?

Hello,

I want to process more requests per second in Ensemble 2015 (soap service). My problem is in a business process that makes a great transformation. I thought that I can put its group size to 4 (the current value is 1), or put 4 business processes and apply, for example, the round-robin algorithm.
Which alternative is better?

Hi everyone

I am new to the bpl diagram. I would like to add an if statement that checks whatever an object is null or not.

I guess that: condition='response.Content != null' would not be ok...

<if name='CheckObj' condition='response.Content != null' xpos='200' ypos='1700' xend='277' yend='2197' >

I tried to search for this information in the documentation but I didn't find any help.

Do you have any suggestions?

Thanks and best regards

Milena

In a Business Process (BPL) I noticed that if I 'm using a "scope" to handle errors then inside the "scope" when a "call" is used, the "request" and "response" action (i.e set for callrequest.prop = request.prop & response.prop = callrespones.prop does NOT work !
The result is that the values of those properties in the callrequest are nulls (I do see the properties names in the content of the callrequest message)

Hi, I think it's a simple question this at the end of something fairly complex

I've a DTL to go to a target class in context

I get the error CLASS DOES NOT callrequest=##class(context.ConnectDocumentRequest).%New()'

I attempted to add code to initate the context with

set context.ConnectDocumentRequest =##class(Penn.EDT.Messages.ConnectDocumentRequest).%New()
