Question
· Aug 9
Manifest or Class?

I have the unfortunate job of installing IRIS and Healthshare (real Healthshare not Healthconnect) on 16 difference instances (tst, stg, prd with mirrors etc). the Dev was set up manually (mostly by me).

So I decided to create a class that installed the db's, namespaces, mappings and HSREGISTRY options , i then decided an installer manifest was a better idea, I keep changing my mind on which!. I understanding manifest is "typically" for dockers to create the environment but have seen ISC use them for creating new setups aswell (outside docker)

The operations manager in our company was using structured logging in IRIS to tail information to an on-prem monitoring tool and started to get concerned with the ever-growing size of the output file. He just leaned across the aisle here and informed me that the output file has no mechanism for rolling this file over at a certain point for archival or disposal. Sure enough, I can't find any documentation to refute this.

Hi everyone,

I am trying to create a treeMapChart in IRIS BI that will then be displayed on my DeepSeeWeb dashboard. In the IRIS BI User Portal, this is an example of what my treeMapChart looks like:

I know there is a huge amount of rectangles in this graphic - I care most about the common components (the largest boxes) but I still want all of the boxes to show. However, it projects to my DeepSeeWeb dashboard as the following:

For example, you start debugging the AAA function, which calls the BBB function, then goes to the CCC^ABC function in a different routine and ends up while executing XXX^XYZ. No other routines or functions are visited in this example. What I would like is to get the record of AAA -> BBB -> CCC^ABC -> XXX^XYZ. No marking each function with recording code should be involved: too time consuming, too many functions in real code.

UPD: Iris has built in %SYS.Trace for this purpose but this class is apparently absent in Cache 2017. Did not find any substitutes yet.

Hey, Developer Community!

We’ve launched a brand-new activity on Global Masters — the Article Bounty!
It’s your chance to share your expertise, help fellow developers, and, of course, earn points while doing it.

👉 Join the August Article Bounty on Global Masters here

Earlier, we launched the Submit an Article Idea challenge — where Global Masters members could suggest new articles, tutorials, how-tos, and more. We received an overwhelming number of fantastic ideas!

👉 Now, once a month, we’ll publish a list of 10 in-demand topics requested by the community.
You can choose a topic from the list, write an article about it, and earn bounty of 🏆 5,000 points when the article is approved.

I have a personal copy of Cache which I use to help me with certain things. The instance resides on my Windows desktop. The apps I use a web enabled. It would be great if I could access my apps via web browser from my laptop without having to keep a copy of Cache on my laptop. It would make it difficult to keep the databases synced. So, if I restart my Cache instance, then I can use get to my apps by entering the url: http://ipadd:57772/csp/user/myapp.cls.

⏯️ Auto-scaling made easy in GKE with InterSystems Kubernetes Operator (IKO)

Kubernetes horizontal pod auto-scaling (HPA) is the key to handle the unpredictable compute workload in healthcare systems. IKO helps orchestrating the IRIS container deployment in Kubernetes including the capability to configure HPA. This demo uses XSLT processing as an example to showcase this type of elasticity.

This great article sparked some recent private discussion, and I'd like to share some of my own thoughts from it.

The motivating concern boils down to: Why do we need coding rules or conventions at all? What happened to the wonderful era of the Renaissance artist-programmer forging their own path, prior to being supplanted by the craftsman and now (even worse) by AI?

Data is at the heart of the digital transformation sweeping healthcare. Radical change requires a new foundation to handle the massive data demands of modern healthcare.

Time to market is crucial as you develop the next therapeutic breakthroughs, genomic insights, and intelligent clinical workflows. You need to deliver them now.

That’s why we’ve extended the power of our InterSystems IRIS Data Platform to address the unique characteristics of healthcare information. InterSystems IRIS for Health is the world’s first and only data platform engineered specifically for the rapid development of healthcare applications to manage the world’s most critical data.

I have a table with 5M rows, the table contains lab observation codes and display names, both columns have type varchar(2000) and both are indexed.

The query looks like:

select code_1_text, count(code_1_text)
  from demo.observation_lab
  group by code_1_text
  order by 2 desc

The table contains ~1000 distinct display names.

It takes 4 minutes for the query to complete on a VM with some pretty old Xeon, 4 cores, 32G RAM, NVME SSD and Linux on board.

I am writing a little app where I press a button on a Zen form. It calls a ZenMethod that uses zenPage.launchPopupWindow() to provide me a way to choose a file. I then click on an upload button that calls a csp cache language script file that runs on the server, that grabs the contents of the file and stuffs it into a global. I want it then close and return to the parent window to continue processing the contents of the file.

I have a custom Buffer class which is designed to capture written/printed statements to the device, to be able to transform the captured text to string or stream type. I have used this in ObjectScript to capture ObjectScript write statements and return a string. I would like to try to use this with a [ Language = python ] method as follows. This class will be called by a scheduled task.

Trying to extract the narrative text from large CCDA files using EnsLib.EDI.XML.Document:GetValueAt method

Getting a MAXSTRING error from the GetValueAt method.. Tried alternate by using GetSubDocumentAt and put it to string. Still it is giving a Invalid OREF method. Is there any limitation on these OOB methods. Also looking for ideas to extract it
