I am running into an issue where a JSON response is missing keys...

{
    "count"0

Within the JSON response I am only looking for two fields portalUrl and portalId. I have tried using $LENGTH and %IsDefined to check if they are valued but neither work. 

Can anyone tell me how I can check to see if a key exists within a JSON response?

Regardless of whether an instance of IRIS is in the cloud or not, high availability and disaster recovery are always important considerations. While IKO already allows for the use of NodeSelectors to enforce the scheduling of IRISCluster nodes across multiple zones, multi-region k8s clusters are generally not recommended or even supported in the major CSP's managed Kubernetes solutions. However, when discussing HA and DR for IRIS, we may want to have an async member in a completely separate region, or even in a different cloud provider altogether.

Hello Community,

When retrieving strings from the DAO, if the string exceeds the capacity of an ObjectScript string variable, it returns <MAXSTRING>. To prevent this, use dao.%Get(key, default, "stream") to retrieve the value as a stream (%Stream.DynamicBinary). However, Why can't we use other stream objects such as %Stream.TmpCharacter instead of %Stream.DynamicBinary/%Stream.DynamicCharacter (I understand It is not possible to create a direct object instance for %Stream.Dynamic* classes) .

I'm trying to use the assign option within a ruleset. I can trace the value with no issues but when I try to assign the same value to a variable of Namespace I get an error.
Ideally I would like to use a variable instead of repeating the Piece repeatedly throughout the rules.

And this is the error that I am getting.

Hello everyone!

FINALLY!! The technical article contest in Spanish begins on Monday 🎉🎉

I currently have an issue with a failed connection in VSCode and need some help.

It doesn't work when using ports 80, 1972, and 7038.

Hi, Community!

Looking to modernize the way you build interoperability screens in InterSystems® products? Take a tour of some recent UI improvements.

Building Integrations: A New User Experience

I need to run  do $SYSTEM.OBJ.Load(<file from linux folder>,"ck") from a linux shell script.

How would I do that?

When AMD published the x86-64 standard in 1999, little did they know they were inventing what would become the de-facto architecture for server CPUs.  But the CPUs of today aren’t the same as ones produced 20 years back – as they have extensions for everything from Advanced Vector Extensions (AVX) to Hardware-Assisted Virtualization (VT-d).

InterSystems would like to take better advantage of these new extensions in upcoming versions of InterSystems IRIS.  While our compilers are smart enough to create optimized code for many situations, some optimizations can only be turned on by explicitly cutting off support for processors that do not have that instruction set. Additionally, we are finding it increasingly difficult to maintain older CPU models to test on.

Hi Community,

A huge thank you to everyone who participated in the Code Your Way to InterSystems READY 2025 challenge! We enjoyed watching your videos and checking out your projects. And now it's time to announce the winners! 

Hey Community!

We're happy to share the next video in the "Code to Care" series on our InterSystems Developers YouTube:

⏯  How Project BEST Transforms FDA Adverse Event Reporting with FHIR

We are receiving an ORU message and the vendor is requesting that we append a new OBX segment at the end of the message and I wanted to reach out to see what options might be available. 

So far, I tried the append action in the DTL editor with a single OBX-3 field but it seems to be appending to the field directly instead of creating a new OBX. I've started looking into if whether I could use a function but wanted to first check with the experts on the Discussion here in case there's an easier way to accomplish this. Thank you. 

I am trying to replicate a REST call that I am able to make via a Postman call within a EnsLib.REST.GenericOperation.

It's been a while since I have messed around with trying to make external REST calls. When I execute my REST call, tSC is coming back with an error and I am trying to pinpoint why. I tried turning on ISCLOG = 5 but when calling the REST Operation from the Testing tool it is not logging anything to the ISC log.

How do we see the RAW request being sent out to verify that my request is formatted properly?

Hi group,

I am trying to take the InterSystems HL7 Interface Specialist certificate test. 

So is this an open book test? is there any Lab involved with vm?  I did the search but I am not able to find such information.

I am trying to find out more information before I actually take the test.

Thank you

Hi,

I've been working on a very basic Interoperability production in my computer. I followed one of the examples in the courses and created a TEST.FileRouterRoutingRule, but when trying to edit this rule, it takes me to the Rule Editor Login Page, where I can't get in (Not even with the _SYSTEM credentials) - Is this functionality unavailable in the community edition?

It helps to remove special characters, such as non-utf-8 characters either control characters or unicode characters from text that is not printable or can't be parsed by downstream systems.

There is also $C(32) in this condition; sometimes NBSP appears in the text and it will not be recognized by TIE, but downstream it displays as "?".

In order to avoid the NBSP issue, the if condition is replaced with a space in order to prevent the error.

Unicode characters only Remove:

Hello IRIS Fans and Welcome to IRIS iRacing!

Here were going to take 3 laps of your time and demonstrate how I wired up my Racing SIM to IRIS for "As Real Time as It Gets" Metrics reporting.  I missed the window for the contest, which happens quite often, but I still ended up 3rd I think in the demo race in the video below.

Below are the technical ingredients for this demonstration for a salad you can post on Instragram.

Epic had changed some of their logic on their Incoming Radiology Results which now require an Ordering Provider even though it is supposed to account for it within the Epic Interface settings.

I was wondering if we are using a custom schema if there was a way to default a value into OBR:16 if it was not valued without having to modify all the DTL's for these Results.

Is there a way to set this via the schema editor or in the background so we don't have to create/update DTL's or create a custom TCP Operation Class??

We have classes in a Production environment that are causing us some issues - example attached.

When we export them from the production environment the XML contains a snippet like the following:

<UDLText name="T">
<Content><![CDATA[
//Property any As list Of %XML.String(XMLNAME = "any", XMLPROJECTION = "ANY") [ SqlFieldName = _any ];

]]></Content>
</UDLText>

When imported and compiled into an Ensemble instance this class works as expected.

When viewed/edited in a development environment we run into issues - the presentation is similar with both Studio and VS Code.

Would like to know if there is an alternative or better way to paginate through a dataset using dynamic SQL than what I am using below. The problem is that as the potential pool of data gets larger, this code slows down to the point of not being useable. In analyzing each line of code below, it appears the slow down is related to the initial rset.%Next() iteration. Is there anything available which does not require a subquery/%VID such as a simple LIMIT/OFFSET?

My code is similar to :

s sql=##class(%SQL.Statement).

We have a machine that serves 4 instances of Cache on VMS systems, one of them is password protected and works fine as they all do. we decided we wanted something beefier and copied it to a server, well all but the one you have to login to works so 3 of the 4 do.  and the odd part is I can no longer get to the management page from anywhere on any machine, http://localhost/csp/bin/Systems/Module.cxw  I get a 404.8 error, I have tried adjusting security and same thing. and a server availability error.

I think it something on the new machine/server that is missing but why only 1 of the 4.

Hello Community,

I have a queue that I need to traverse and perform operations on. To distribute the workload across multiple processes, I used a Work Queue Manager do process and I'm not expecting any status from it So, I skipped Sync / WaitForComplete in my implementation

Hi all,

I'm reviewing an older Cache routine and came across this line of code: from file ^ZDBKCRON

S $ZT="^%ETSDK"

Error trap

/home/oper/script/cache_db_backup -t        # Daily CacheDB Backup

 produced the following output:

 <NOROUTINE> *%ETSDK
<ERRTRAP>

-----------

From what I understand, this is setting up an error trap, but I'm not entirely clear on how it works, especially in modern InterSystems IRIS environments.

Could someone please help explain:

1. What exactly does this line do?
2. Is %ETSDK a standard system routine? I can't find it in our environment.

I cloned @Yuri Marx's langchain-iris-tool repo and modified docker-compose yaml per this post:

Hello everyone,

I am using a class that inherits from %RegisteredObject and %JSON.Adaptor to generate a JSON string from its instances.

However, one of the properties in my class is of type %Library.DynamicObject, as in the example:

ClassExtends%RegisteredObjectAs

When calling %JSONExportToString() on an object of this class, the JSON generated for the property is incomplete or malformed. It seems the default %JSON.Adaptor doesn't correctly handle properties of type .

Example of the resulting JSON:

Previously (in Caché 2018), I used

Hi devs!

Suppose I have an instance of a persistent class:

Set##class%OpenId

Class is an ancestor of %JSON.Adapter.

How can I convert it to dynamic object with the properties that person.%JSONExport() provides?

{

Couldn't find a right method. 

set dynObj = ##class(%ZEN.Auxiliary.altJSONProvider).%ObjectToAET(person) works, but adds id and classname, which I don't want to be added:

zw dynObj
dynObj={"_class":"dc.Sample.Person","_id":1,"Name":"Elon Mask","Title":"Associate Accountant","Company":"InterSystems","Phone":"799-933-5569","DOB":31390}  ;

Thoughts?

Hey Community,

It's time for the new batch of #KeyQuestions from the previous month.

I have a Linux server that has multiple instances installed on it (according to my documentation).

What is the best command to show:

- what instance are installed?

- what instances are running?
I did run 'iris list' but it shows only one instance.
