#Ensemble

The article is a step by step guide for beginners to learn how to build a RESTful web service consumer (or client) in Ensemble. The provider can be any RESTful service, but the example is based on the service we made during the previous sessions.

It is more than obvious that many client development environment has programming libraries or containers to build a RESTful client.For example in the earlier sessions we used Java Script to access services.Ensemble as a container also offers client functionality.Let us have a quick list what Ensemble offers.

I want Healthconnect to be the middle man between my client and my respository vendor. I've setup

HS.IHE.XDSb.RepositoryServices > HS.IHE.XDSb.Respository.Process>HS.IHE.XDSb.DocumentSource.Operations

Is this the correct approach?

Anyone has already been successful in connecting google calendar to Ensemble ?

We are using object EnsLib.EDI.XML.Document and the method OutputToString -- ( context.XMLObject.OutputToString("C(utf-8)") ), In the string that we get back, Hebrew characters are unknown and we get question mark instead.

How can we overcome it?

Cross-origin Resource Sharing (CORS) is one of the basic security features built into browsers. CORS controls accessing resources from a HTML page in domains other than the original domain. It is particularly important for AJAX calls. Since RESTful services can be used as data provider to any AJAX call, you have to be able to control cross-origin access. By default services are not allowed to do CORS. You are going to learn how to enable it for Ensemble RESTful services.

The Resource Map class (the subclass of %CSP.REST) controls whether CORS is enabled.There are two approaches to do.

 Windows 7 and some other Microsoft Operating Systems can shutdown too fast for large applications, such as a Cache instance with a large amount of data and changes, to close gracefully. This results in the instance being forced down by the OS and so causing problems on the next start up.

To solve this we can change the OS shutdown timeout values to give Cache more time to close gracefully. We do this by editing some settings in the Registry.

1.Click Start (on Win 7) and type “regedit” and make sure you run registry editor as administrator.

2.Go to

Hi All,

We are Using Ensemble 2014, Windows Server 2012 64 bit operating System.
We need to sense whether Htpps is alive or not.
In Cache we tried %HttpsRequest Library we set https property and port=443. But it doesn't work.
Anyone help us plz.

Thanks, Sansa

Preface: our small, but very ambitious company called “Black Mushroom Studio” came up with an idea for an e-commerce project and a mobile app that would let users pay for certain goods/services via a payment aggregator.

What we had initially: an Android app skeleton that, of course, liked communicating via HTTP and JSON, and a payment system with an API – web services with SOAP content.

Goal: make it all work together.

Hi-

Can someone please explain the affect of the Failure Timeout on an ensemble business operation with a EnsLib.HL7.Adapter.TCPOutboundAdapter

Is this setting indicating the number of seconds that the operation will attempt to resend a message to a target before it fails?

How does this setting affect message processing of messages that fail because of a missing or failure response code that comes back in an HL7 message response?

A beginners guide to develop Ensemble RESTful web services.

Background

Before you start reading this short introduction please go through the on-line documentation of Ensemble with special attention to chapter “Creating REST services and clients with Ensemble”.

The approach in the documentation is undisputable the fastest and easiest way to create RESTful services. As a beginner I went through the documentation and I had several questions. This short article is listing those questions plus my humble answers.

When I refer to documentation I mean Ensemble 2016.2 and onwards.

What does an Ensemble

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!

Thanks!

Hi All,

We have an application running on Ensemble 3.0.0.2185, And we want to upgrade to latest version of Ensemble.

Can somebody please outline the process of upgrading from version 3.0.0.2185 and all the risks involved?

Thanks

Framing refers to the characters that mark the start and end of an HL7 message (or other types of framed messages).  Most HL7 services and operations have a Framing setting that allows the user to define this framing.  The most common choices are available as defaults, but with the AsciiMM/NN setting, components can be configured to recognize any framing characters.

The most common framing error is ErrEndBlock.  Other typical errors include a warning saying "Discarding received non-HL7 data", a warning saying "Returning unused unexpected n-char segment", and "Discarding leftover input ''".

I need to deploy an Ensemble production to several different clients.  Each client requires certain production settings to be set specific for them, things like pool sizes, IP addresses, SSL configurations, etc.

What is the best way to customize configuration settings when a production is deployed?

Right now I have a developer/free version of Cache 2016.1 on my local dev box but it doesn't have Ensemble installed, is there a way to get Ensemble?

After having gone to the 2016 Global Summit I want to play around with it on my own and see what it's capable of.

Thanks

Is there any issue with using a pool size setting greater than 1 for an  inbound file service? The reason I ask is we can easily dump 100k+ files to a folder in minutes, but using a pool size of 1 can take hours for that backlog to clear.

Hi all

I was just in the process of implementing a custom SOAP web service to receive a message with an embedded base64 encoded HL7 message when I noticed the above-mentioned OOTB service.I've been unable to find any documentation describing its use but it appears to expose a single operation named Send which takes a single parameter (a %Stream.GlobalCharacter) named Input.Does anyone know if this service is indeed useful and if so quite how the HL7 should be passed in?

Hi All 

I have a process that I want to analyze and find bottle necks (e.g BO that had taken to long) something similar to the SQL query optimizer

Any suggestions?

Thanks

Hi All

I have a BP which has a transformation. 

when I run the process I end up with the following error: 

----

ERROR <Ens>ErrBPTerminated: Terminating BP Propirion.BP.GetServices # due to error: ERROR <Ens>ErrGeneral: Object is immutable
+
ERROR <Ens>ErrGeneral: Object is immutable 

----

I have created a context named : HL7Message  type of: EnsLib.HL7.Message  and in the start of the BP assigned the request to it  (using set in assigned activity)

What did I miss ?

Thanks

Hi

Some time ago, I was started to work at a new company even in other country, and more important in a different sphere when I have not been worked before, in HealthCare.It's a very new project even for company.Since I have not experience in HealthCare, I looked at what I can use in my project, and found that I should not reinvent the bicycle, and think about how to store all my data which I need and how to get access to this data.And I can use FHIR, which is looks like everything what I need, what else I need it's just a client.

What is the syntax for referencing the source config from my process OnRequest method?

This short article was motivated by a problem of one of my customers. They use Ensemble to integrate many systems, some of them use just plain files.

So they naturally selected File Outbound Adapter to write into target file. Things were running smoothly for years, until recently, when the volume of data being written to the file reached large size of tens of megabytes. The operation took around half an hour to complete, causing timing problems where subsequent operations within the process had to wait, and third party system was not happy to wait so long.

The customer's code looked somehow

Hi

I do not really have much information yet about an upcoming mission but i know it is about to seal a flatfile and then send it further. I think  SHA256 HMAC will be used. There is a fixed sealkey to be used each time. Does anyone know if the Ensemble supports this ? I have looked in the documentation but not really found anything .

This is the first follow up after the post about headstarting SAPJCo3 with Ensemble and HealthShare ( https://community.intersystems.com/post/headstart-connect-sap-using-sapjco3-ensemble-and-healthshare).

Using the wizard which is available with Version 2016.1 and up (currently only through direct call in the webbrowser http://<server>:<port>/csp/<namespace>/EnsPortal.Dialog.SAPJCO.BaseConfiguration.cls ).

Make sure you have a running production with a configured SAPJCoOperation.

Hello everyone,

Does anyone know how to create integration tests using the Cache unit test framework in order to test an Ensemble production?

For example, what would be the best way to create automated tests for a BPL that calls multiple business operations (SQL, WebService ...)?

Should we create some kind of mock service/operation to simulate the response from the business operations ? 

The FT keys InterSystems currently make available to us in the zips from the download pages are due to expire at the end of this month (31-Aug-16). Will there be new keys soon?

Also wondering when we might expect new FT builds for 2016.2 and 2016.3. The last published ones were 24-Jun-16 and 16-Jun-16 respectively.

I haven't seen an Atelier update for a while either.
