Hi beloved members of the Community!

It is very common in the daily life of IRIS or Health Connect users that it is necessary to install new instances or update the ones they already have and in many cases it is not these same users who carry out the installation, but rather systems personnel who often do not take into account the particularities of the assignment of permissions necessary for the installation.

Hi,

I running an SQL so I can find the databases with the largest amount of free space. This is in case I can compact the databases.

However SQL cannot find the SYS.Database table.

Can someone please explain how to fix?

[SQL]TEST:%SYS>>select * from SYS.Database
ERROR #5540: SQLCODE: -30 Message:  Table 'SYS.DATABASE' not found

[SQL]TEST:%SYS>>  << entering multiline statement mode, 'GO' to execute >>

FHIR repositories, applications and servers typically serve clinical data in small quantities, whether to return data about a patient, their medications, vaccines, allergies, among other information. However, it is common for a large amount of data in FHIR/JSON format to be requested to be used to load into Data Lakes, identifying study cohorts, population health, or transferring data from one EHR to another. To meet these business scenarios that require large extractions and loads of data, it is recommended to use the FHIR Bulk Data Access feature provided by HL7 institution.

Hi all! Here I would like to share how we use vector search and GenAI with InterSystems technology. As an example, I'll describe BG-AppealAI project, which our company submitted to the InterSystems Vector Search, GenAI and ML Contest. BG-AppealAI application can write an appeal if you upload an insurance contract and the insurance company’s letter with a refusal to pay medical expenses. Of course, we are aware that at the moment AI has not reached such a level as to create ready-made legal documents.

Hi, this post was initially written for Caché. In June 2023, I finally updated it for IRIS. If you are revisiting the post since then, the only real change is substituting Caché for IRIS! I also updated the links for IRIS documentation and fixed a few typos and grammatical errors. Enjoy :)


In this post, I show strategies for backing up InterSystems IRIS using External Backup with examples of integrating with snapshot-based solutions. Most solutions I see today are deployed on Linux on VMware, so a lot of the post shows how solutions integrate VMware snapshot technology as examples.

Hey everyone.

I came across some issues when setting up Freeze and Thaw batch scripts for use with VMWare in a Windows ecosystem, and I wanted to share what I found in the hopes it can help others. This was undertaken in an environment using Healthconnect 2019.1.x.

IRIS not up (2)

It seems that the sample script from the documentation in my my case would tell me that the environment was not running (despite it running). To correct this, I provided the filepath to the Mgr location as so:

c:\InterSystems\HealthConnect\bin\irisdb -s"C:\InterSystems\HealthConnect\Mgr" -U%%SYS ##Class(Backup.General).

Question Mike Yackanich · Jan 13, 2021

Hi all,

I have a passthru REST setup using EnsLib.HTTP.GenericService and EnsLib.HTTP.GenericOperation. Works well.

I am adding some logic to the Operation and for some scenarios I want to return an HTTP 40x response status code.

I create an httpResponse object within the Business Operation, but I can't figure out how to set the http response status code that is returned to my Posstman client that initiated the request. I set StatusCode=400, and StatusLine and ReasonPhrase properties - but when the ultimate requestor (Postman) receives the response back it is a 200 status code.

Hey everyone.

As I have been working with IRIS (nee Caché) for some time now, I decided to take a look at how I manage things like functions and scripts that may not belong to a single namespace or environment, but should still have a home.

I have taken to creating a github repo where I can keep track of a single .cls of "general functions" that I can then drop into an environment when required.

I have an operation using $ZF this operation ran and did not error but the job has been active and it can not be stopped I have tried stopping it from the front end and through the terminal using ##class(ENSLIB.Job).%New() Stop method. Now my production will not update even if I add a new item to the production I cannot update the item is there a way to force stop  this job.

Question Ali Chaib · Feb 7, 2025

I have a scenario where I send a GET request to a broker and receive a FHIR response. When I attempted to use the built-in InterSystems functions to convert this FHIR response into SDA, the transformation failed—likely because it is not a standard FHIR request.

How should I handle this situation? Is there a recommended approach to processing FHIR responses in this context?

Additionally, if I manage to convert the FHIR response into a request format, I noticed that the broker sends a Task resource.

Question Ali Chaib · Feb 7, 2025

I understand that InterSystems provides functions to facilitate transactions between FHIR and HL7 via the SDA segment. My question is:

  • Does this transformation only work when InterSystems receives FHIR requests and converts them into HL7, or does it also support responses?
  • Specifically, if our operation sends a GET request to a broker and receives a FHIR response, does InterSystems support transforming this response into an SDA segment automatically?
  • Or should we manually parse and modify the response to handle it according to our needs?

What would be the best approach in this scenario?

The IKO allows for sidecars. The idea behind them is to have direct access to a specific instance of IRIS. If we have mirrored data nodes, the web gateway will (correctly) only give us access to the primary node. But perhaps we need access to a specific instance. The sidecar is the solution.

Building on the example from the previous article, we introduce the sidecar by using a mirrored data node and of course arbiter.

Hello,

I am new to InterSystems FHIR server implementation and in process of evaluating it. (R5)

I try to create a Task referencing a CarePlan resource as above.

I got the following error message and I wonder what could be the mistake as it used to work against another FHIR server implementation. (the referenced CarePlan resource does not exist but I guess that in this case the error code would be different?

In this article, exceptions are covered.

Working with Exceptions

Instead of returning a %Status response, you can raise and throw an Exception. You are then responsible for catching the exception and validating it. IRIS provides five main classes to handle exceptions effectively. Additionally, you can create custom exception class definition based on your needs.

These exceptions are different from %Status, so you can't directly/efficiently use the exception object with $SYSTEM.OBJ.DisplayError() or $SYSTEM.Status.DisplayError().

You may encounter errors during any point of program execution, and there are several ways to raise and handle these exceptions. In this article, we'll explore how exceptions are handled efficiently in IRIS.

One of the most commonly used return types is %Status, which is used by methods to indicate success or failure. Let's begin by discussing %Status values.

Working with %Status

The %Status return type is used to represent errors or success. Many system methods return %Status when an error occurs.

Question Thomas Haig · Feb 4, 2025

At the moment we're creating multiple BPLs are using a router (or another BPL) to direct to these based on a unique key modulo the amount of BPLs available, e.g. if we have 3 BPLs created.
Message key = 1 mod 3 + 1 -> BPL02
Message key = 2 mod 3 + 1 -> BPL03
Message key = 3 mod 3 + 1 -> BPL01
FIFO only matters in that each messages for each key is processed in order.
What we were considering doing is increasing the pool size to 3 and programmatically creating a BPL on each thread that processes messages that would be directed to it, rather than having to create multiple BPLs into the production.

Hello,

When setting up a new web app in iris (iris is in a container) iris complains that a WSGI framework is not installed. I have installed python into the container as well as both flask and django via the python virtual environment (see second screenshot) and the python language server is running

Is this the wrong way to install flask? How do I get the container version to recoginize that flask is installed?

When removing a segment in DTL for hl7 using foreach the segment doesn't actually get removed and leaves a blank segment. 

i.e. 

MSH|^~\&|SendingSystem|ReceivingSystem|202301241000||ADT^A01|12345|P|2.4
EVN|S|202301241000
PID|1|MRN12345|1^^^^KEEP~2^^^^Remove~3^^^^Keep|M|19800101|  
PD1|PatientAddress^Street^City^State^Zip
PV1|I|INPATIENT|BED123|DoctorID|202301241000|202301241000

This blank segment to be removed

I read the notes and thought it might be about swizzling at https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?

Question Phillip Wu · Feb 3, 2025

Hi,

I have Objectscript routine stored in an external Linux file which I've called /my/home/DisplayDB.int

This file does not include any Class definitions and is simply a set a Object script routines. I think this is called INT objectscript

The file looks like this:

set db=##class(Config.Databases).DatabasesByServer("",.dbList)
for i=1:1:$LENGTH(dbList,",") {
  set dbName= $PIECE(dbList,",",i)
  write dbName,!
}

How do I load and compile the Objectscript code?
Do $system.OBJ.Load("/my/home/DisplayDB.int", "ck")
How would I run the code?
do ^DisplayDB
Thanks in advance for any help
