#InterSystems IRIS for Health

InterSystems announces its seventh preview, as part of the developer preview program for the 2023.2 release.  This release will include InterSystems IRIS and InterSystems IRIS for Health.

Discontinuation of the Private Web Server (PWS)

A major topic in this release is the discontinuation of the Private Web Server (PWS) from the installers.  This feature has been announced since last year and it's removed from InterSystems installers, starting with this developer preview.

See this note in the documentation. Additional information related to this topic can be found here.

Recently I started moving some of our JDBC Gateway configurations over to using the Microsoft JDBC Gateway driver instead of using the jTDS open source driver. I have noticed since then that those Objects that are using Microsoft JDBC Driver are throwing a lot more errors than the jTDS driver ever did, which I can understand however I am puzzled that I keep running into an issue with the Java Gateway Service within the Interoperability engine.

Every so often I will start seeing "Gateway Server failure timeout on 127.0.0.1:55550" followed by "Gateway Server did not respond to PING request.

InterSystems FAQ rubric

You can set individual error pages for the following Web Gateway error messages/system responses:

• server error
• server busy
• server unavailable
• server timeout
• connection closed

Settings are made on the Web Gateway Management screen ([Management Portal] > [System Administration] > [Configuration] > [Web Gateway Management] > [Configuration] > [Default Parameters]).

In the Error Page section of the Default Parameters menu, set the filename of the html page to display or the URL to redirect to when an error occurs.

Good morning,

first of all thank you for taking the time to read and answer this question.

Recently, since we have upgraded to HealtShare 2020, we experienced the fact that when opening in the Studio the Process (.bpl) and Transformation (.dtl) classes, it asks us to log in, i.e. username and password, almost every time we open a new Process or Transformation.

However, in previous versions, I think we had HealthShare 2016 or 2017 or 2018, and in it, you could log in from the Studio in Processes and Transformations, logging in 1 time only.

Hi Community,

Enjoy watching the new video on InterSystems Developers YouTube:

⏯ Introduction to InterSystems Products

InterSystems has corrected two defects.

The first defect can cause an ECP application server to hang. This defect is only relevant to ARM and IBM Power processors; it is present in version 2022.1.2 and 2022.1.3 of InterSystems IRIS®, InterSystems IRIS for Health™, and HealthShare® Health Connect. The correction is identified as DP-423661. The defect is addressed in all future versions. 

The second defect can, in rare circumstances, cause dejournaling to hang. This defect is present in versions 2020.4, 2021.x, 2022.x, and 2023.

Did you know that with InterSystems IRIS for Health™, you can create a FHIR Facade that enables healthcare apps to send and receive HL7® FHIR® data?
 Find out how in this learning path (3h 30m), which includes a hands-on exercise (20m).

This is a sample application that demonstrates how to use the InterSystems IRIS for Health FHIR Repository to build a FHIR Repository with OAuth2 authorization, the FHIR endpoint will be the resource server and Google OpenId will be the authorization server.

InterSystems FAQ rubric

You can search for a specific global variable in the journal file using the ByTimeReverseOrder query of the %SYS.Journal.File class and the List query of the %SYS.Journal.Record class.

The role of each query is as follows.

A) %SYS.Journal.File query of the ByTimeReverseOrder class

You can get the journal file name. Results are returned in descending order of journal file name. 

USER>set stmt=##class(%SQL.Statement).%New()

USER>set status=stmt.%PrepareClassQuery("%SYS.Journal.File","ByTimeReverseOrder")

USER>set rs=stmt.%Execute()

USER>while rs.%Next() { write rs.

These two articles describe how to extend business components with additional properties:

1. https://community.intersystems.com/post/how-customize-ensemble-settings

2. https://community.intersystems.com/post/creating-custom-captions-intero…

I have one more question about drop-down editor. Is it possible to pass to its URL the value of another business component property, not just @productionId? Something like: 

class MyOperation extends ( EnsLib.REST.Operation, Ens.

Hello,

I want to add a couple of properties to a custom Transform class to give the user the ability to edit its properties directly in the Business Process visual editor. It can be easily done with other Production components, but I can't find in the documentation how to do the same with my Transform. Is it possible?

And another question is about how to use the 'aux' parameter of the DataTransform.Transform method if my component is non-visual?

Hi all,

I am using %Library.ResultSet to execute my query which I have something like this.
Query GetABC() As %SqlQuery [SqlProc]{

}

After I execute this query and a resultset it returns from this. Now What I want to know is the SQL statement which will have the values dynamically added into while execution.

I have been successfully able to transform hand-written medical test results documents to HL7 ORU_R01 v2.x, then to SDA, which will be trasformed to FHIR or C-CDA.
However, I have a category of documents which contains reference range in multiple date formats, which are measured for each gestation period. 
For example, below is one of the documents.
 

Analyte: HCG, Value: 1968, Unit: mlU/mL 

Reference Range:
Week of gestation: 3, Range: 5.8-71.2
Week of gestation: 4, Range: 9.

FHIR has revolutionized the healthcare industry by providing a standardized data model for building healthcare applications and promoting data exchange between different healthcare systems. As the FHIR standard is based on modern API-driven approaches, making it more accessible to mobile and web developers. However, interacting with FHIR APIs can still be challenging especially when it comes to querying data using natural language.

Introducing the FHIR - AI and OpenAPI Chain application, a solution that allows users to interact with FHIR APIs using natural language queries.

When creating custom Business Hosts, it's often necessary to add properties to the class for additional settings that will be used in the initialization or operation of the host. The property name itself isn't always very descriptive, so it's an advantage to have a custom caption display with the field.

In Caché, it was fairly straightforward:

TEST> Set ^CacheMsg("EnsColumns","en-us","<property name>") = "<caption>"

But It involves a bit more effort in IRIS ...

InterSystems FAQ rubric

Whether the value of a local variable is an OREF or not can be determined using $IsObject(). Let v be the variable you want to check,

$IsObject(v)=1 // v is an OREF
$IsObject(v)=0 // v is not an OREF
$IsObject(v)=-1 // v is an OREF but does not point to a valid object

Note that $IsObject(v) will give an UNDEFINED error if v is undefined.

To avoid UNDEFINED errors, it is recommended to use $Get like this:

$IsObject($Get(v))

Visual Studio Code, like Atelier, connects to IRIS through the Web Server and a web service, unlike Studio that connect to the SuperServer port.

What about the VS Code terminal?  Does that open a shell with SSH or does it also use a web service?

In other words, does an IRIS developer using VS Code need direct access to the IRIS instance with SSH or the SuperServer port, in addition to the external or private web server to execute terminal commands?

Is that different with linux vs. Windows?

Hi All,

I am facing some issues. I am having a SQL query that is executed using %SQL.Statement ExecDirect() method. Now I want to convert it into Embedded SQL using &SQL().
But where clause is dynamic in my case and It may contain 3-4 clauses.

Hey everyone, 

Here we are again. New year, new contest, new project, old reasons.

Triple Slash is in the house!

SQLBuilder is a flexible and powerful SQL query string builder for InterSystems IRIS,

With SQLBuilder you have nice and clean object oriented methods, instead of having to use concatenation and substituition to generate dynamic queries.

• IKO is a tool to deploy InterSystems IRIS for Health on Kubernetes.

Hi

We've been asked to develop a HL7 interface, but the end system has very different needs than any we've ever interfaced with before. We need assistance to determine if these needs are things HealthShare can support that we're just not aware of, or whether we'll need to develop some custom code to accomplish this.

This end system wants us to send HL7 messages completely asynchronously, one after the other without waiting for any form of ACK or NAK.

When manually coding REST services and using GET /api/mgmnt/v1/:namespace/spec/:application/ to return an OpenAPI spec, how do you specify supported properties (OpenAPI Properties in Use | Creating REST Services | InterSystems IRIS Data Platform 2021.1) like responses, definitions, and information in paths like summary and description?

GET /api/mgmnt/v1/:namespace/spec/:application/ | Creating REST Services | InterSystems IRIS Data Platform 2022.2

Using a very basic manual REST service that returns a JSON string I get a pretty basic spec that is not really helpful when it comes to documentation.

Hi InterSystems Community

We recently had an issue where we weren't able to parse a JSON HTTP request, but the issue went by unnoticed. We also did not have a trace of what the raw HTTP request was that we couldn't parse. I'm looking at improving our this by:
Tracing the raw request using $$$TRACE

Raising an alert which will hit our Ens.Alert router which will compose and send an email

I'm having an issue with consistently raising the alert (I've seen it raise an alert before, and then it wouldn't raise it again on a subsequent message), and also the error back does not really make sense.

InterSystems announces its sixth preview, as part of the developer preview program for the 2023.2 release.  This release will include InterSystems IRIS and InterSystems IRIS for Health.

Highlights

Many updates and enhancements have been added in 2023.2 and there are also brand-new capabilities, such as Time-Aware Modeling, and enhancements of Foreign Tables (but still as an experimental feature). Note that some of these features or improvements may not be available in this current developer preview.

Another important topic is the removal of the Private Web Server (PWS) from the installers.

I am trying to write a class method to return the value of a object element.  Input to method is the object and element. I am not getting a value returned. What am I missing?

ClassMethod GetObjectFieldValue(pObject As %DynamicAbstractObject, pField As %String) As %String
{
    quit:pObject="" ""
    quit:pField="" "" set tResponse=""
    set tResponse = pObject.

Hi, I'd like to ask if it is possible to use an arbitrary JSON as a DTL source. Can the IRIS DTL editor parse JSON of arbitrary structure and display it as a tree?
