We have to route messages in a Process Class by their source (using either the SourceConfigName from the Message Header or the Source in the Message Body.

The inputs are standard HL7 messages from different Services but need to be routed on to different Processes depending on where they come from (not my design & I can't change it now) does any one have any suggestions how I could do this?

Source control and the production class

When you create an Ensemble production your namespace acquires a new class definition. For example here is what the class that defines the Demo.Loan.BankUSProduction production in the ENSDEMO namespace looks like when opened in Studio:

Enterprise Monitor

Has anybody managed to get Enterprise Monitor to work to monitor multiple namespaces on manay instances?

I am hitting an issue trying to get a local instance namespace working.

I have this error for my first local namespace sytem configured.

"Ensemble encountered an error while loading this page"

Multiple Namespaces vs One

We are beginning a project to switch over to a differnt EMR for our inpatient system, and we are wondering if others out here have worked on a similar project and how did you handle your Ensemble environment?

Currently, we use one namespace for all of our HL7 interfaces. Has anyone used a separate namespace for a project to keep the build separate until go-live? What were the pros/cons for you using a different namespace? Or did you use one and what issues did you have because of it?

Who does Windows think I am?

When my COS code is executing in a Caché process it might want to interact with the host operating system. For the purpose of this post I'm focusing on a Windows host, but much of it applies to other host OS platforms as well.

A common example of host OS interaction is when my process wants to read from or write to a file. What credentials will apply when Windows is checking whether or not to allow me access to the file?

To answer that we need to consider another question. How did our process start?

If you've got more than one developer on a project, do you each work in your own namespace? Or do you all use a common namespace?

Through my work at George James Software I have encountered many different Caché and Ensemble development setups. At risk of over-generalizing, the older and more established users of InterSystems technologies seem more likely to have all their developers working in a common namespace, whereas the newer 'converts' tend to favour giving each developer their own namespace.

Filtering incoming records?

We have a situation where we want to detect and ignore documents/records at the earliest possible point based on certain criteria. We have an existing "CDA Preprocessor" in the workflow which is an XSL transform. This is what our contractors are planning to utilize to "filter" these documents. This doesn't really make sense to me. I see XSLT as a way to manipulate the contents of a document and filter certain peices of data. In my brain, I would use an Ensemble business rule to detect the criteria and route the document as necessary.

The cdirectmgr utility will no longer be included with product distributions beginning with the Caché 2016.2 release . This was an older VB application (predating the Caché cube) which allowed users to define server connections for Visual M/Caché Direct applications. As VB 6 is no longer supported by Microsoft, we will no longer ship this component. The same functionality is already available from the cube utility.

It is also posted in Compatibility blog.

What is the recommended approach to handle the following scenario: Large number of HL7 messages are serviced via Ensemble. Those messages are then transformed and routed to an Operation which calls a web service which does a number of different activities. If will do address normalization, location geo coding, MPI lookup and resolution, and insert into a SQL Server database to stage for an analytics product. Unfortunately all of this work takes time and the first thing that happens in the web service is a lock taken out on the Patien in SQL Server.

Zen Reports has offered multiple choices for direct printing including use of Adobe Reader or Foxit reader. Recent changes in Windows 10 and in the readers themselves have made it no longer possible to invoke these readers from background processes in Windows 10 and all future versions. Because of this Zen Reports will no longer support printing with these tools on Windows 10.

Windows 10 support was added for 2015.1 and 2015.2. On Windows 10, the only option for direct printing with Zen Reports will be Qoppa JPDFPrint.

Why Atelier? And what about Studio?

I have been meaning to make a post about this topic for a few weeks and the other day an issue came in through the WRC about it so it seems this is a conversation we should be having. I want to begin by taking a few moments to explain "Why Atelier" then we can talk about what this means in the general sense for Studio and Atelier and Caché developers. We have wrestled with what to do with Studio for years. When I moved to Product Management in 2008 this was already a "thing". At the time we could not reach a consensus. Some felt Studio was fine as is.

I'm working on a proposal for a deployment tool development project and I was wondering if anyone had any experience with such a thing.

We use Healthshare and implementations for new clients are tedius and lengthy. Lots of ensemble service, registry value, lookup tables, namespaces and other things have to be created and configured.

I would like to create a Zen or CSP page based deployment tool that can do all this with a few parameters and some custom code.

Hi all,

I was wondering, what is your favourite public cloud provider?

What is your level of engagement with the cloud provider? Are you testing their infrastructure? In which case I'd expect you being progressing a parallel test with at least a second provider ;-) Or, are you already running a production environment?


OK, so, let me be the first one to share my experience with one specific cloud provider.

Ensemble 2016.1


Does anybody know when Ensemble 2016.1 will be general availability?

We are holding off upgrading, providing the wait won't be too long.

We do have a production including a SOAP.OutboundAdapter that make a request to a .NET WCF Service. The response from that service vary in size. When it come to large one, we talk about maybe 8000 records (with 6-8 attributes per record) in xml, the adapter always give a timout. Even if we put a high number of seconds or set -1. After 1 1/2h still nothing get back. It's just standing there and waiting for ever.

Our .NET developer have look at it (on the WCF-service) and from ther point of view they say that it seems like Ensemle can't handle such big responses.

We heard from a customer who wanted to display a version number as a read-only production setting. During the build on the build server, this version number is added to the Production class. This works fine, and the Version is displayed in the Portal, but the customer wanted to write protect it, so the enduser can’t change it. The customer had defined the setting like this:

Property Version As %String;
Parameter SETTINGS = "Version:Info";

We advised the customer to define SETTINGS like this instead:

Parameter SETTINGS = "Version:Alerting:label"

Do to unforseen circumstances the Atelier build that was distributed with the Cache 2016.2 field test had certain incompatibilites which prevented it's effective use with the server that it was bundled with.

We are working on remediating this regretable situation and will provide a compatible Atelier in the 2016.2 field test refresh which is scheduled for today Monday, 1st of Februrary.

We sincerely apologize for any inconvenience so caused.

I'm designing a workflow for PHR via FTP. What I've done is create a single FTP adapter to pick up files from multiple customers. A router then accesses a lookup table and determines if a particular customer is allowed to send a particular message type to the state. If not, the message doesn't go out. It seems like everyone is against this approach (other than my CEO, thankfully), including Intersystems:

2016.2 Field Test Kit 2016.2.0.585.0

I am pleased to announce the next in the series of 2016.2 field test kits, 2016.2.0.585.0.

In the two weeks since the last field test posting Development has made over a hundred fixes and improvements in Atelier, Enterprise Manager, Ensemble and Caché.

In Atelier alone there were over a dozen changes including a fix for the incompatibility issue that Jamie Newton described in his posting of February 1.

In Caché major areas of focus include:

Is there any simple way to query data about processed messages in all Ensemble productions?
What I ultimately would like to do is to periodically export that data to another system and run statistics on it.

I've been digging around in the SQL tables view and Ens.MessageHeader seems to contain most of what I'm after.
Using ODBC I could access that table view and query data, but only for one namespace per DSN it seems.
