A button on a web page can capture the users voice. IRIS integration could manipulate the recordings to extract semantic meaning that IRIS vector search can then offer for new types of AI solution opportunity.

The fun semantic meaning chosen was for musical vector search, to build new skills and knowledge along the way.

Hi all,

I'm triying to create a SOAP Pass-through acording to Configuring Pass-through Business Services instructions, but I'm not able to run it

I'm using the following WebService

Has anyone tried using Server-Sent Events with Caché/HealthShare/Ensemble and angularjs?

 I have dynamic sql select query ,

Set resultset = ##class(%ResultSet).%New()

 set sql = "SELECT COUNT(*) FROM "_tableName_" WHERE "_fieldName_">='"_fromDate_"' AND "_fieldName_"<='"_currentDate_"'"

 SET SC = resultset.Prepare(sql)

 SET SC = resultset.Execute(sql)

How can I print/view the count ?

I need to make changes to  OBX 5 which shows as immutable

I have tried ConstructClone, ThrowOnError, and Streams but I can't get the syntax correct

Example

OBX|1|TX|2000.02^REASON FOR REQUEST^AS4|142|REASON FOR REQUEST:      Total Cost:           0.00||||||O
                                        ^^^^ remove "REASON FOR REQUEST"                                                                            ^^ add cr/lf so down stream reports can be formatted more easily

I have the code done to parse out the "REASON FOR REQUEST" but I need to make the OBX 5 show the change.

You can use the WriteToConsoleLog method of the %SYS.System class to write any message to the console log.

The following is an example:

%SYS>write##class(%SYS.System).WriteToConsoleLog("xxxxx log message",0,0)
1

For details on the parameters that can be specified in the WriteToConsoleLog method, please refer to the following document:

Greetings,

Is it possible to change the date format from YYYYMMDDHHMMSS to YYYYMMDD in a DTL? How?

I tried ConvertDateTime() without success.

Thank you!

Is there a generic process for "walking" the structure of a virtual document - eg an HL7 message (EnsLib.HL7.Message) or an XML document (EnsLib.EDI.XML.Document).

At least we'd want to be able to visit all "nodes" (HL7 fields or sub-fields, XML nodes) in the virtual document and be able to work out/generate the Property Path (so we could call "GetValueAt"). 

We can just about come up with something generic for HL7, since it only nests down to 4 levels within each segment, though we're using numeric Property Path's at that point rather than symbolic ones (MSH:1.3 etc).

I have a HL7 DTL in which I'm doing a lookup to a table based on a code value in the IN1:3 field.  That incoming code may have a 1 to 1 mapping, or 1 to many mapping in a table.  If it's a 1 to many, the values in the lookup table are comma delimited.  If it's 1 to 1, that IN1 segment will map straight across.  If it's one to many, I need to create additional IN1 segments.  For example, if the incoming code maps to three, I need to map the original IN1 segment with one of the mapped codes, then create two additional IN1 segments with the other 2 codes for a total of 3 IN1 segments.  I'd like

This can be done with TRY-CATCH:

#dim ex As%Exception.AbstractExceptionTRY {
    //Code that causes an error
  }
  CATCH ex {
     do ex.Log()
  }

If you use ^%ETN, call it from the BACK entry (BACK^%ETN).

Hello there 🙋‍♂️,

I'm looking towards a functionality alike Python's difflib, but made with Intersystems products. I already know could embed Python code within IRIS but thought maybe there was a development already done for handling deltas, with a different approach or extra utils.

Even if I find such a library after comparing both might still go with difflib or any other more suitable. Intend to use it for a cross-environment checklist/check tool.

Please find below a sample of HTML rendering computed and made with difflib, with a few lines of code:

thanks ! best regards,  

We are calling a REST web-service from Ensemble using EnsLib.HTTP.OutboundAdapter and redefining the adapter class to set custom headers as described by @Eduard Lebedyuk here: How to set Content-Type

During development we accidentally stumbled across puzzling behaviour - we now suspect that the %Net.HttpRequest object created in the linked example is being reused in the following scenario:

Hello everyone,

I'm looking for a practical project guide to help me gain hands-on experience with InterSystems Ensemble HL7. Ideally, this guide would walk through building a small project — something that covers key concepts like message routing, transformations, and interoperability.

If there's a resource that also includes step-by-step instructions and perhaps even offers a certification upon completion, that would be perfect.

Any recommendations or guidance would be greatly appreciated. Thanks in advance! 😊

Looking for a SQL query or any other method to find the Unique/distinct message counts for all productions or at least per production namespace within a given time frame. For e.g TimeCreated = January 2025 (Whole month)

I have used the following, but its not restricting the numbers based on the TimeCreated filter. Every time a new message is processed by system, its added to the total. I am running the query in today's date

Select Sum(MsgCount)

From

(Select DISTINCT TargetConfigName, count(DISTINCT SessionID) as MsgCount

FROM ENS.MessageHeader 

If there is a way we can find how much a particular namespace is utilizing the O/S CPU and memory, that will be great in resource utilixation as well as capacity planning.

Hello, dear colleagues.

I need to connect to a remote JavaGateway from an Ensemble service.

I am trying to use the EnsLib.JavaGateway.Service with a remote host where the JVM is running.

I can successfully ping the remote Java Gateway from EnsLib.JavaGateway.Service, and Ensemble reports that the service status is OK.

There are no network issues, and all necessary ports are accessible.

My requests work without any problems when I specify localhost in EnsLib.JavaGateway.Service. However, when I specify a remote JVM, I get the following error:

Hi ,

I have a scheduler task and an associated class that works.

Class Sample.Util.CreateTask Extends (%SYS.Task.Definition, %Persistent)
{

Parameter PROPERTYVALIDATION = 1;

Parameter TaskName = "Sample.Util.CreateTask";

Method OnTask() As %Status
{
// Perform the logic
}

}

Is there a way to Enable or Disable the above task "CreateTask()" from an external function/Method/class ?

The compile step in VS Code when using the InterSystems VS Code extensions appears to modify line endings in our class files when newly pulled from remote repo.

What steps can we take to stop this happening? / What settings can we modify?

We are doing local development with client side source control using git (BitBucket Cloud repository). We were previously using GitLab (locally hosted) and didn't have this issue. Developers are all on Windows machines, as are all the Ensemble instances. We believe we have autocrlf = true in all our local git configurations.

Steps to reproduce:

I have created a class file that I want to execute daily to gather Metrics (Message Header, Space Available, etc..) and write the data into a Cache table. Now that I have written the class I want to add it to the Task Scheduler within Ensemble to run every morning. How do I go about getting the class file created as a Task within the Task Scheduler? The Documentation isn't as clear cut for creating custom tasks as one would expect.

As of InterSystems IRIS® data platform version 2025.1, InterSystems is officially deprecating MultiValue and including it in the Deprecated and Discontinued Features list. While InterSystems will continue to support existing customers using MultiValue, it is not recommended for new applications.

Hi All,

How can I customize the file path of my FTP outbound adapter.

I have a custom business operation that extends "EnsLib.FTP.InboundAdapter", in which I need to update the file path of my FTP server location.

We have some ObjectScript code in a custom business process:

When Log Trace Events is ticked on the business process in the Production view in the management portal, the argument is obviously computed.

Our question is whether the argument is computed when Log Trace Events is not ticked? Don't want to accidentally include something in a $$$TRACE() statement that takes enough computation to make a performance difference when released to production, even though the final output is not written to the event log.

Hello!

This article is a small overview of a tool that helps to understand classes and their structure inside the InterSystems products: from IRIS to Caché, Ensemble, HealthShare.

In short, it visualizes a class or an entire package, shows the relations between classes and provides all the possible information to developers and team leads without making them go to Studio and examine the code there.

If you are learning InterSystems products, reviewing projects a lot or just interested in something new in InterSystems Technology solutions — you are more than welcome to read the overview of ObjectScript Class Explorer!

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?

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?

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 -> BPL02Message key = 2 mod 3 + 1 -> BPL03Message key = 3 mod 3 + 1 -> BPL01FIFO 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
