This formation, accessible on my GitHub, will cover, in half a hour, how to read and write in csv and txt files, insert and get inside the IRIS database and a distant database using Postgres or how to use a FLASK API, all of that using the Interoperability framework using ONLY Python following the PEP8 convention.

While reviewing our documentation for our ^pButtons (in IRIS renamed as ^SystemPerformance) performance monitoring utility, a customer told me: "I understand all of this, but I wish it could be simpler… easier to define profiles, manage them etc.".

After this session I thought it would be a nice exercise to try and provide some easier human interface for this.

The first step in this was to wrap a class-based API to the existing pButtons routine.

I was also able to add some more "features" like showing what profiles are currently running, their time remaining to run, previously running processes and more.

The next step was to add on top of this API, a REST API class.

With this artifact (a pButtons REST API) in hand, one can go ahead and build a modern UI on top of that.

For example -

It is with great pleasure that the CIUSSS de l'Estrie - CHUS is sharing the mocking framework it developed and presented at the InterSystems Summit 2017.  I will update this post with more detailed instructions in the next few weeks but I wanted to share the code and presentation quickly :

Requirement: Transform source XML message to target JSON.

step1: First create json equivalent xml from any online tool.

step2: use add in  studio utility create persistent classes from json equivalent xml and compile it , now target persistent classes are ready

step3: Do the above step for source xml or xsd and generate persistent classes for source and compile it

step4: complete the DTL by selecting root node from source, target persistent classes and complete the mappings and compile it

One of my colleagues had developed an interface in Health Connect (HealthShare 2019.1) to add large amounts of data to an external SQL Server database. The data comes from many text files with delimited rows and data for one table per file. There is a business process to read a file line by line and send an Insert Request to an operation.

DTL Transformations and GetValueAt/SetValueAt calls on HL7 messages will truncate any fields longer than 32K.  To avoid this, the methods GetFieldStreamRaw and StoreFieldStreamRaw must be used when dealing with fields that might be larger than 32K.  OBX:5 is a frequent example.  These methods have some subtleties and must be used carefully.

This can't be done by simply dragging from left to right in a DTL.  It must be done with a code action.  Also, the StoreFieldStreamRaw call must be the last edit made to the segment because the segment becomes immutable after that.

IRIS/Ensemble as an ETL

IRIS and Ensemble are designed to act as an ESB/EAI. This mean they are build to process lots of small messages.

But some times, in real life we have to use them as ETL. The down side is not that they can't do so, but it can take a long time to process millions of row at once.

To improve performance, I have created a new SQLOutboundAdaptor who only works with JDBC.

BatchSqlOutboundAdapter

Extend EnsLib.SQL.OutboundAdapter to add batch batch and fetch support on JDBC connection.

Successful Troubleshooting

During the last weeks, I was working on various issues and problems related to SW development.
I found that quite often problem analysis was mostly chasing issues just on the surface
but not really attacking the deeper reasons of the problem and follow the consequences.
It's like the doc that stops your leg bleeding but doesn't see that it is broken.

InterSystems technologies are renowned for their high performing databases, which support the systems and operations of many organisations. However a key ingredient to this success is the quality and maintainability of their code. 

The quality of code can impact everything from speed and ease of fixing bugs and making enhancements, to the overall performance of your organization and your ability to get ahead in the marketplace. 

By ensuring your code is maintainable, you can reduce approximately 75% of the systems life cycle costs*. This is why, at George James Software, the solutions we build are always straightforward and written in high quality code - because we know that this solid foundation can positively impact the rest of your organization. 

With a maintainable system you're able to reduce your overall maintenance as any issues that occur are significantly faster to identify and fix. This means you're free to allocate that time and budget to enhancements, enabling you to get the most value out of your applications and ultimately better support your organization. 

Keep an eye out for our next few posts about what a maintainable system looks like and the tools that can help you keep your code maintainable, in order to help you to reduce those maintenance costs.

In this article I will demonstrate the following :

  • Update ReferencesRange(OBX:7) against ObservationIdentifier(OBX:3.1)[TestCode] from database by using custom utility function
  • Update Abnormal Flag(OBX:8) against ObservationIdentifier(OBX:3.1)[TestCode]  and ObservationValue(OBX:5)[Result] from database utility function
  • Route Message based on Abnormal Flag(OBX:8)

Below is the primary and transformed HL7 2.5 ORU_R01 message:

I work as an Integration Engineer for United States Department of Veterans Affairs (VA). I work on a Health Connect production which processes many RecordMap files. I do not fully understand RecordMaps and I wanted to develop an application for the Interoperability contest where I could learn more about working with RecordMaps. I browsed InterSystems documentation for inspiration on how to start. I was happy to find CSV Record Wizard.

The latest release of Serenji focuses on the debug experience. Not only can you now debug on the spot, no matter where you are or what you're doing, but we've also added some smaller features that will make debugging more straightforward. 

  • Run and Debug CodeLenses - clickable links above each class method, procedure, subroutine or extrinsic function.
  • Intuitive prompting for entrypoints and arguments - when debugging a class method, produce, subroutine or extrinsic function. 
  • Shaded read-only background - to clearly differentiate between documents which are editable and those that are read-only. 
  • Program output in debug console - output is shown in the debug console. 
  • Serenji commands on Server Manager's namespace trees - allowing you to launch Serenji through Server Manager.

Hi developers, 

We've incorporated VS Code's support for multiple concurrent debug sessions and consoles into the latest release of Serenji

So if you're working with processes that relate or are dependent on each other, you can now debug them together. Just launch a second Serenji debug session (F5) whilst the first one is still active. 

This short video below shows how it works. We hope you find this feature useful!
