#InterSystems IRIS for Health

For background, I've developed code that relies on %JSON.Adaptor functionality across an entire package of classes in our codebase. In regenerating these classes with %JSON.Adaptor as a superclass, I've encountered compilation errors from the JSON adaptor generators in certain classes, triggered by certain property types or parameters that are incompatible.

Hello Community,

Is it possible to retrieve/find all the names of subroutines, procedures, or functions from a deployed routine?. in the routine below, how can I extract names like x2 and execsql? I’ve just tried using openId on %RoutineMgr  but it didn’t help.

xdeploy.mac
xdeploy
 quit
x2 ; test1write123q
execsql(sql) ; test2Set tResult = ##Class(%SQL.Statement).%ExecDirect(,sql)
 Return tResult

Thanks

Developing with InterSystems Objects and SQL – In PersonJune 9-13, 2025

We are attempting to send HL7 messages over to CBOARD NetMenu over HTTP using SSL. We set this up using the EnsLib.HL7.Operation.HTTPOperation adapter. When we attempt to send the message we are receiving 

MSH|^~\&|||DIETOE|A6M0|202505131437||ACK^HTTP^415|00|P|2.1 MSA|AE|9165602|HTTP (N)ACK 'HTTP/1.1 415 Unsupported Media Type'

The vendor mentioned something about putting a SOAP/XML wrapper around the HL7 message but isn't that what the HTTPOperation adapter does? Why would we be getting Unsupported Media Type. How would we go about setting the Media Type for the HTTP HL7 message?

Hello Community,

I executed the below query in the %ZLANGC00.mac routine. It returns results when using dynamic SQL, but not with embedded SQL(returns 0). 

 &SQL(SELECTcount(*) INTO :Cnt FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE='BASE TABLE'")
 Write "SQLTablecount : "_Cnt,!
 Set tResultSet = ##class(%SQL.Statement).%ExecDirect(,"SELECTcount(*) FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE='BASE TABLE'")
 Do tResultSet.%Display()

Thanks!

Introducing Smart Clinical Sidechick — the intelligent, no-drama partner your EHR wishes it could be. She reads FHIR data in real time, interprets lab results without ghosting, and explains clinical alerts like she actually cares. Built with GPT-4 brains and YAML sass, she’s not here to replace your main EHR—just to make it look bad. Tired of irrelevant alerts and cryptic warnings? Sidechick serves up real, explainable insights, not vague “elevated risk” vibes. And when your backend crashes, she doesn’t panic—she self-heals. Secure, responsive, and (unlike your last vendor) emotionally

Hi Community,

I recently needed to interrogate some folders/sub-folders to retrieve filenames using cache object script(COS) and I implemented it in the following way.

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

{
    "count": 0,
    "pageInformation": {
        "offset": 0,
        "size": 10
    },
    "items": []
}

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. 

Hello Community,

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.

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.

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.

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:

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??

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:

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

Now I see this:

Can anyone please help me which function i can use to handle this error.

In a project I'm working on we need to store some arbitrary XML in the database. This XML does not have any corresponding class in IRIS, we just need to store it as a string (it's relatively small and can fit in a string).Since there are MANY (millions!) of records in the database I decided to reduce as much as possible the size without compressing. I know that some XML to be stored is indented, some not, it varies.To reduce the size I decided to minify  the XML, but how do I minify an XML document in IRIS?I searched across all the classes/utilities and I could not find a ready made

One of the challenges of creating a DICOM message is how to implement putting data in the correct place. Part of it is by inserting the data in the specific DICOM tags, while the other is to insert binary data such as a picture - In this article I will explain both.

To create a DICOM message, you can either use the  EnsLib.DICOM.File class (to create a DICOM file) or the  EnsLib.DICOM.Document class (to create a message that can be sent to PACS directly). In either case, the SetValueAt method will allow you to add your data to the DICOM tags.

Hello IRIS community,  

InterSystems Certification is developing a certification exam for InterSystems IRIS Developer professionals, and if you match the exam candidate description given below, we would like you to beta test the exam.

I am struggling with returning a SQL Query Result that may have multiple rows that can be searched.

set query = "SELECT Facility FROM FROM osuwmc_EnterpriseDirDB.RelationshipMedCtrID WHERE OSUmedcenterID = ?"SET rset = ##class(%SQL.Statement).%New()
 SET qStatus = rset.%Prepare(query)
 SET rset = rset.%Execute($Get(ID))
 do rset.%Display()

I need to take the values that are returned and say search them for a single value. How would I go about returning the EnsLib.SQL.Snapshot into a Array or List for it to be searchable.

Hi developers!

This will be a very short article as in April 2025 with Lovable and other Prompt-to-UI tools it becomes possible to build the frontend with prompting. Even to the folks like me who is not familiar with modern UI techics at all.

Well, I know at least the words javascript, typescript and ReactJS, so in this very short article we will be building the ReactJS UI to InterSystems FHIR server with Lovable.ai.

Let's go!

Hi,

We're having an issue with some messages being sent to a downstream system from Healthshare.  Part of the free text in the NTE segment is displaying with special characters on the system front-end but is not present in the HL7 message that we send to them.  We are guessing that this is a result of some of the text being copied and pasted from something like MS Word. The '?' on their system is just representing an invalid character. 

Is anyone aware of a way to prevent this occurring? We are sending the messages using the 'cp1252' encoding.
