Hi,

I can't work out how to use the Cache CA Server to process certificate request from external clients!

We are setting up an interface where we use SSL/TLS 'Mutual Authentication' to allow a client system to securely transmit document to our server. (they are off-site and hosting a service for us)

I am not a security expert, but my understanding of setting up mutual authentication where my instance of ensemble is the server, and it is receiving messages from a client is as follows

Hi -

I'm trying to follow the documentation, but I seem to end up in a circular reference, where the docs say "Login to TrakCare" to get access to the Layout Editor, with a link to "Logging Into TrakCare", and then that whole sections assumes that the account being used has been created, but doesn't seem to point to any means of actually creating the account in the first place.

Where is it described in the HealthShare Documentation, how to create a TrakCare login account?

Enterprise Monitor and HealthShare

Enterprise Monitor is a component of Ensemble and can help organizations monitor multiple productions running on different namespaces within the same instance or namespaces running on multiple instances.

Documentation can be found at:

http://docs.intersystems.com/ens20161/csp/docbook/DocBook.UI.Page.cls?KEY=EMONITOR_all#EMONITOR_enterprise

In Ensemble 2016.1 there were changes made to make this utility work with HealthShare environments.

This article will:

  • Show how to set up Enterprise Monitor for HealthShare sites
  • Show some features of Enterprise Monitor
  • Show some features of Enterprise Message Viewer

For this article, I used the following version of HealthShare:

Cache for Windows (x86-64) 2016.1 (Build 656U) Fri Mar 11 2016 17:42:42 EST [HealthShare Modules:Core:14.02.2415 + Linkage Engine:14.02.2415 + Patient Index:14.02.2415 + Clinical Viewer:14.02.2415 + Active Analytics:14.02.2415]

In this posting I want to raise the profile of a feature that arrived in 2009.1 but is perhaps not very well known.

It is sometimes useful to make certain packages, globals or routines available to all of your namespaces. Of course you can add the necessary mappings whenever you create a new namespace, but here's a simpler way.

Git and Atelier

Hi,

I'm in the process of trying to convert my team to a Git-based workflow for source code version management (we use Ensemble and HealthShare, but build a lot of customizations on top). We are having a hard time working with Atelier in this regard for a few reasons:

I wanted to share a little tidbit which is in the Studio documentation (http://docs.intersystems.com/cache20152/csp/docbook/DocBook.UI.Page.cls?...) but many people who have been using the InterSystems Studio for a long time missed the addition of this *very* useful feature, and every time I mention this to an audience I see at least one face light up because of how excited they are to learn about it!

Within Studio, the Output pane (View -> Output) is actually misnamed. It is actually an Input/Output window which can be used to run Caché ObjectScript commands!

Running HealthShare XSLTs from Terminal

HealthShare uses a lot of XSLTs. These are used to convert IHE medical documents to SDA (internal HealthShare format) and back to IHE formats, to create summary reports, and to deal with IHE profiles (e.g., patient information query, document provide and register). Customers may customize the XSLTs to customize reports or for other reasons.

For debugging and development, it is very convenient to be able to run an XSLT from Terminal.

Routing Rules

Is there a way in the routing rule to compare two fields in two different segments? For example, for the message below we need to compare one Identifier in PID-3 (uiytr5678906^^^^CKS)against another in MRG-1 (uiytr5678A06^^^^CKS). Both will always have the same IdentifierTypeCode (PID-3.5/MRG-1.5), but the ID number can be different. Just to clarify, we only want to compare the CKS IdentifierID, not the entire field or all the identifiers in the MRG-1 or PID-3 field.

1. Scope and Objective:

Recently we supported a few NHS cases that required TIE (Trust Integration Engine) integration with the PKB service. Hence this article is meant to be a 10-minute quick guide to describe a demo solution (simple configurations and end-2-end implementation steps) for Health Connect (Ensemble) Integration with PKB (Patient-Knows-Best) service.

Hi ,

In HSBUS we have out of box operation HS.IHE.XDSb.Repository.Operations to route CCD's from HSBUS to Edge gateway.

Earlier it was working fine, but for maintenance we have to rest the DEV environment, Now its throwing below error. I have verified all registry configuration and the CCD feed is also same, nothing is changed except reset. Can someone help me, where to look for this problem or what I am missing here.

I running a query and get the results inside a result set. Now I have to iterate through the result set many times. From the doc I've seen only the Next() method. Is there a way to reset the cursor? Otherwise what is a good data structure to save multiple rows of a table?

My code in this case is something like this:

set sql = "SELECT * FROM MY_TABLE WHERE X= '"_Y_"'"
set status = ..Adapter.ExecuteQuery(.rs, sql)
// somehow iterate the rs more than one time

Is this available anywhere (for Health Connect)? I've found a few presentations but they are aimed at entry level.

We're looking at supporting more and more FHIR, REST plus OAuth interfaces in future. I've built some of this into older versions of HealthShare and Ensemble but it's desirable to move to supported versions.

We would be using Healthshare as a facade to other systems.

PDF Compression Using Ghostscript

Introduction.

Have you ever felt like your PDF files take up too much space on your server? As you collect more and more of these files, you might run into storage issues that can be costly to solve. But what if there was a way to shrink the size of these PDFs by 50% to 70% without compromising the document's visual clarity.

Today, we're going to explore a solution for this problem that I really like: GhostScript.

Tools for CDA/CCD?

I have a tool I absolutely love for HL7 v2 analysis and manipulation. It's called 7edit. I'm wondering if there is anything similar for HL7v3/CDA/CCD. I know it is considerably more complex, but I still have hope.

So far the best resource I've found is http://www.cdapro.com/. I'd love to hear anyone else's tips for tools or resources.

Is it a good practice to set the MAXLEN value of %Library.String property type? Will it lead to wasted storage if its not really using it?

For example, I have to store a 5 characters long string into the below str field. Which of the statement is recommended?

Property str As %String;

vs

Property str As %String(MAXLEN="5");

This is more for my memory that anything else but I thought I'd share it because it often comes up in comments, but is not in the InterSystems documentation.

There is a wonderful utility called ^REDEBUG that increases the level of logging going into mgr\cconsole.log.

You activate it by

a) start terminal/login

b) zn "%SYS"

c) do ^REDEBUG

Suppose I have an image and need to convert that image into a PDF for inclusion in an HL7.

I know that Zen Reports can display an image in a PDF but I do not want to view the image in a web page. I just need to convert the image to PDF in a Process and then include that PDF in an HL7. The workflow would be like this:

Get image -> Convert image into PDF -> Include PDF in HL7 OBX.

I know how to do the last part to include PDF in HL7 OBX. Just need ideas on the first part.

I was searching for the most simple way to connect from visual studio code to my local instance via terminal without having to change any window.

I know this can also be achieved via telnet but seems a bit overhead if you're in your local machine.

For me the simplest sollution is to open a terminal window in VS Code, navigate to the /bin folder of your instance installation and run .\csession.exe INSTANCENAME

For simplicity you can just include your /bin folder in your path so you don't even need to navigate there

HealthShare HealthConnect and Information Exchange version 15.03 support import transformations from C-CDA 2.1 to SDA. You can find these transforms in your installation's csp/xslt/SDA3 directory. For general information about import transforms, see "CDA Documents and XSL Transforms in HealthShare" in Overview of Health Connect.

Among the enhancements to import functionality added in connection with C-CDA 2.1 support is the ability to preprocess your C-CDA input files prior to the transformation done for import.

Hello,

When creating an outbound X12 file (834, 835, 837, etc), what's the easiest way to keep a segment count to use in the SE01 element? Other mapping tools I've used either detect it's an X12 file and do this automatically, or there's an option to keep a count after each outputted segment. The Data Transformation tool within Health Connect doesn't seem to have similar functionality, but I could just be missing something. Any help would be greatly appreciated!

Thanks,

Jason
