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

I am working on a BPL to take data from a MS SQL database and create an HL7 Materials Message for our EMR. I have done this plenty of times in the past however I am running into an error.

"Remote Gateway Error: JDBC Gateway SP execute(0) error 0: Access to the remote server is denied because no login-mapping exists."

What is confusing is that this BPL doesn't differ from any of my other BPLs in connecting to MS SQL Server. I know I am missing something..

Is it possible to hide certain properties in a class from displaying in the BPL visual editor, if you want to prevent drag and drop from accessing them or otherwise controlling or restricting their behavior?

Virtual document messages, such as EnsLib.HL7.Message, have hidden fields, such as Source, that do not show, presumably since the field list is rebuilt from the document schema. Setting the flag Internal, or XMLPROJECTION = "NONE" doesn't do it. Trying to follow the Virtual Document precedent to rebuild or edit the field list seems like a heavy list.

Hi ,

I'm currently working on a BPL (Business Process Language) in InterSystems Ensemble, and I'm facing an issue when trying to call the SendRequestSync() method within a code activity. My understanding is that SendRequestSync() is part of Ens.BusinessProcess, and since Ens.BusinessProcessBPL extends Ens.BusinessProcess, I believe it should be accessible.

However, during compilation, I'm encountering an error stating that the method doesn't exist in the class.

As I begin our adventure into using an External FHIR Repository, I wanted to see what opinions people have about a design Idea I was working on.

I want to create a way that my Team has the ability to send a Message Type, and the system knows from that Message Type which FHIR queries to execute and return the Response back to the user, sort of like a FHIR Query Hub. Does this sound reasonable?

BPL TechFAQ

The Business Processing Language - for orchestration and long-running business processes.

Ensemble can orchestrate calls to external systems. Very often this is done to implement or automate a long-running business process - that is, real business processes where people interact with a series of different systems to complete complex tasks. BPL (the Business Processing Language) provides a graphical way to create these orchestrations.

Could anyone help me out?

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,

After cloning "http://github.com/intersystems/Samples-Integration-RedLights" sample code I imported sample production from /home/project/Samples-Integration-RedLights/data/EndStateProduction.xml file to my local system.

Now I am getting the error "ERROR #5021: Directory '\home\project\shared\Samples-Integration-RedLights\data\SampleFiles\' does not exist." in my service.

While modifying the Directory path I am getting below error :

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 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?

Hello everyone!

I have set up an EnsLib.REST.GenericService with an EnsLib.HTTP.InboundAdapter which forwards the http requests received by a web app to my Business Process.

I would like to parse HTTP multipart/form messages I am receving and be able to iterate over the various fields within the request body, accessing its content type and the content itself.

As far as I understand I should use the %Net.MIMEReader class which should return a list of %Net.MIMEPart, one for each field within the request. However if I do :

Sign and verify in SMIME format

In some project, I found the need to use SMIME format https://www.ietf.org/rfc/rfc3851.txt, basically is an standard used to wrap a message together with its signature using a certificate (usually X509). Ensemble don't have a single class to do that but inside the Ensemble installation we have the openssl utility, so in this example I use the "openssl smime" command to sign or verify a message.

The example has two Business Process that able to sign or verify and in order to test I made a simple production.

Hope this helps

Hi,

I have a process in which i call a rest operation in a while loop, get a response in JSON format of 50 issues, with paging, meaning this call will happen until the total amount of issues will be returned. each JSON is parsed into a proxyObject, and inserted to a list. later the entire list will be sent to an SQL operation which will write the data in the appropriate tables.

I have a BPL Business process which always processes messages - mainly it waits for responses since downstream systems are seriously async.

I need to update this process.

Wwould the existing instances of this Business Process complete correctly after the update?

My BPL changes would result in:

  1. New S method in the Thread class
  2. New OnResponse method in the context class

Both changes are in the middle of the process, so there are S/OnResponse methods before and after my change.
