We often run into connectivity problems with HealthShare (HS) deployments in Microsoft Azure that have multiple HealthShare components (instances or namespaces) installed on the same VM, especially when needing to communicate to other HS components while using the Azure Load Balancer (ILB) to provide mirror VIP functionality. Details on how and why a load balancer is used with database mirroring can be found this community article.

InterSystems and Intel recently conducted a series of benchmarks combining InterSystems IRIS with 2nd Generation Intel® Xeon® Scalable Processors, also known as “Cascade Lake”, and Intel® Optane™ DC Persistent Memory (DCPMM). The goals of these benchmarks are to demonstrate the performance and scalability capabilities of InterSystems IRIS with Intel’s latest server technologies in various workload settings and server configurations. Along with various benchmark results, three different use-cases of Intel DCPMM with InterSystems IRIS are provided in this report.

PerfTools IO Test Suite


This pair of tools (RanRead and RanWrite) is used to generate random read and write events within a database (or pair of databases) to test Input/Output operations per second (IOPS). They can be used either in conjunction or separately to test IO hardware capacity, validate target IOPS, and ensure acceptable disk response times are sustained. Results gathered from the IO tests will vary from configuration to configuration based on the IO sub-system. Before running these tests ensure corresponding operating system and storage level monitoring are configured to capture IO performance metrics for later analysis. The suggested method is by running the System Performance tool that comes bundled within IRIS. Please note that this is an update to a previous release, which can be found here.

REST JSON webservices presentation

Hello Community!

This article gives an overview of the REST JSON webservices developed for TrakCare.

These webservices allow users to access TrakCare data from outside of the software, mainly through external apps.

They are developed in REST with ObjectScript, and they allow data access in four modes:

Hundreds of users at TrakCare and HealthShare sites around the world rely on the InterSystems CCR Application (Change Control Record) to track their changes and deploy their configuration. InterSystems is excited to announce that following the launch of the Angular-based Documentation and FAQs this summer, the CCR application is now ready to accept beta testers to try out further expansion of the Angular UIs.

Users at CCR-controlled sites who wish to participate in the beta testing of the new UI can "opt-in" using the following steps:

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.

I am very pleased to announce that tomorrow (Dec 3) at 9 AM Cambridge time we plan to enable the new CCR UI for all users. No downtime should be required for the go-live. Existing beta testers will not see any change, but for non-beta testers the new Frost-based Angular UI will replace the legacy CSP-based application for the home page, navigation, System Details, and several other parts of the application.

Hi All,
I am a product owner for a 3rd party healthcare product.
We have built FHIR integrations with Cerner and EPIC using their FHIR sandboxes and would like to do the same for Trakcare.

Essentially we can lookup a patient record on the FHIR sandbox and import their demographics into our product. Switch out the sandbox credentials for production and we can integrate directly into the customers data.

Does a similar service exist for Trakcare?

Hi Experts

I am trying to pull the code tables Information and this code table has linked code table not exactly obviously joined by SQL tables or columns. This is confusing me. Please can you clarify how to link these two tables.

I will be generic to ensure, any privacy is protected

CT_Hospital has CT_Staff linked in.

When CT_Hospital has data, for that relevant hospital code, CT_Staff can be clicked and data entered.

When I see in the Components - > Items I do not see any SQL table or SQL column common between CT_Hospital and CT_Staff.

I'm running Windows 10 x64 Pro 20H2 with Intersystems Cache ODBC driver v2018.01.00.184. I've setup a System DSN using the 64-bit of ODBC Administrator.

I've been getting inconsistent results using my regular application (Microsoft Power BI) which I use through ODBC to query my hosted TrakCare T2017 instance.

Using Microsoft ODBC Test Tool (part of MDAC 2.8 SDK) I can verify I get the same errors as in Power BI. They seem to be ODBC driver related but I can't pin it down.

ODBC Test Tool GUI shows:

TrakCare iprint


I'm trying to configure iprint for trakcare.

My trakcare runs on linux IRIS(SUSE).

iprint is from MicroFocus [previously Novell]

iprint is a print facility that many printers support where there is a virtual queue for each AD user.

You can log onto any iprint printer using your AD credentials and you can access your virtual print queue. You can then physical print from that virtual queue.

Has anyone configured this for their trakcare?
In order to do this I need to:
- map each trakcare user to their equivalent AD user

I have a question for people currently in the community who support TrakCare implementations.

Are you all currently working through the migration from Crystal/Zen over to Logi Reports?

What are you plans for the Zen reports you can't migration off for example the HTML letter template?

I have spoken with a few people regarding this topic but starting to get concerned if there is a call in the near future to decommission ZEN/

Collect TrakCare's datas

Hey everyone,

Here's my issue, I would like to develop a web application which use and send datas to TrakCare app, but I really don't know how to communicate with TrakCare's datas.

With a little research, I think I could use "RESTForms" or "EnsembleWorkFlow" but I don't really get how...

Can somebody help me and tell me the way forward ?

I am a clinician and we use Trakcare Lab LIMS at our institution.

We understand histopathology reports are directly typed, stored and uploaded directly to the LIMS.

For clinical audit purpose we need to download these reports directly in text format in bulk. Can anyone offer some technical assistance in retrieval of these histopathology reports? Is there any script that can be run to access, retrieve and download these reports?

Hello -

I was curious as to if there is any online documentation for TrakCare on how to default collapse this encounter timeline graph? I can't seem to find anything online so I figured I would reach out here. Instead of the timeline auto-expanding, I would simply like for it to be collapsed when opening up a patient's record.
