#InterSystems IRIS for Health

I have a production with a HLv2 HTTP Listener. For demo purposes, I need to send HL7 messages directly from a browser. Here is an example (React/typescript):

const message = "MSH...";
const args: RequestInit = {
      method: "POST",
      mode: "no-cors",
      body: message
 }

const response = await fetch(IRIS_SERVER_HL7_HTTP, args);
// await checkResponseAsync(response);
return await response.text();

Technically it works, and Chrome network monitor lets me know that operation completes successfully (response code is 200 and I see the ACK), but the browser restricts fetching the response

I would like guidance on the most effective approach for converting UTC time, such as "2023-11-24T14:00:00.000Z," to the format "202311241400," while taking into account the 1-hour time difference during UK summer time. Any suggestions or advice would be greatly appreciated.

InterSystems announces its first 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, enhancements of Foreign Tables, and the ability to use Ready-Only Federated Tables. 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.

Hello,

I am quite new to the InterSystems world. I have one of my OBX 5 fields having this value "blood work was done<>tested positive for anemia<>tested negative for hepatitis". I have a lookup table "AnemiaResults" with a key of TESTED POSITIVE FOR ANEMIA. My issue is that since OBX 5 has other characters/text  (and OBX is a repeating segment) , I am unable to use the Exists function. Any idea how to tackle this? Any assistance will be greatly appreciated. 

After any installs upgrades we get the following 

04/13/23-18:00:00:978 (18668) 0 [Utility.Event] d:\intersystems\healthshare\mgr\enslib\ (Database is readonly)
04/13/23-18:00:00:979 (18668) 0 [Utility.Event] d:\intersystems\healthshare\mgr\hslib\ (Database is readonly)

I think we must have before altered these to not read-only. 

Not sure if the isssue is by default 

-Running task as user with %ALL rather than SYS user

- Should the dbs be as default in the all backup list 

- Should these be not ro so it backs up without error? 

InterSystems FAQ rubric

You can use the system routine ^DBSIZE to estimate the backup file size (see also Note 1).

^DBSIZE estimates the file size of full, cumulative, and differential backups of the databases selected in the database backup list.

The database backup list is created from [System Administration] > [Configuration] > [Database Backup] > [Database Backup List] in the Management Portal.

For more information, please refer to the document below.

Estimate backup size with ^DBSIZE [IRIS]

An execution example is as follows.

Curious if anyone has modified the HL7 TCP/IP Service and adapter class to receive an HL7 message, ACK it, and just dump it straight to a file? I don't want the messages in the engine at all - just receive and dump. Has anyone done this before and have code you're willing to share?

Thank you very much in advance!

Hi All! Wanted to share a recent video we released, for those of you who may be getting started with InterSystems HealthShare Health Connect Cloud. This video walks through all the management tasks you can complete via the InterSystems Cloud Services Portal that you use with Health Connect Cloud. Feel free to reach out if you have questions!

Welcome, dear members of the community!

In this article we are going to demonstrate the great potential that IRIS/HealthConnect makes available to all its users with the use of Embedded Python and we are going to do it by developing a small production that will allow us to recognize and identify the faces present in a JPG file from some images that we will use as a reference.

I'm working with a client who has InterSystems in his hospital to the management of patients and nurses. Now he want to develop a web app which can schedule nurse sift. Is there any way I can authenticate the user from his hospital InterSystems and get data from the system when ever the user login through the web app.

In Windows, set the processes with the following image names as monitoring targets.

[irisdb.exe]

contains important system processes.
* Please refer to the attachment for how to check important system processes that should be monitored.

[IRISservice.exe]

This is the process for handling IRIS instances via services.
When this process ends, it does not directly affect the IRIS instance itself, but stopping IRIS (stopping the service) is no longer possible.

[ctelnetd.exe]

%Service_Telnet Starts when the service is enabled and becomes a daemon process to access IRIS via Telnet.

Hello All, 

I'm trying to sign some custom JWT with x.509 certs but running into a problem with the signed JWT containing some information I need in the JOSE header.

Is there a way to get the "X5C:[]" header included in the signed JTW? IS this as easy as setting something like the following

Set JOSE("x5c") = "public key"

Thanks

It is clear how to get the request header value with a specific name:

Class My.RestController Extends %CSP.REST
{

ClassMethod processRequest() As %Status
{
    #dim request as %CSP.Request 
    set request = %request
    set h = ##class(%REST.Impl).%GetHeader("...")
    ...    
    return $$$OK
}

But I can't figure out how to enumerate ALL the request headers (and also get all values).

Let's say you have Python including variable-length arguments methods. How can you call it from ObjectScript? 

deftest1(*args):return sum(args)
  
deftest2(**kwargs):
  a1 = kwargs.get("a1",None)
  a2 = kwargs.get("a2",None)
  return a1+a2

You can call this "a.py" from ObjectScript as below.  For **kwargs argument, create Dynamic Object in ObjectScript and put it into methods with <variablename>... (3 dots) format. 

set a=##class(%SYS.Python).Import("a")
    write a.test1(1,2,3)   ;; 6set req={}
    set req.a1=10set req.a2=20write a.test2(req...)   ;; 30

InterSystems has corrected a defect that can cause corruption of databases and journal files on AIX systems with IBM POWER8 or later POWER processors. This defect can be triggered only when database or journal encryption is in use.

 To trigger this defect, the following conditions are required:

• The environment uses database or journal encryption
• The environment also uses data-element encryption
• An encryption key used for data-element encryption has been deactivated

If the environment satisfies all these conditions, then the key schedule used for database or journal encryption can become

Hello InterSystems HL7 Community,

InterSystems Certification is developing a certification exam for InterSystems HL7 interface specialists and, if you match the exam candidate description given below, we would like you to beta test the exam. The dates the exam will be available for beta testing are March 28 - April 30, 2023. Interested beta testers should sign up now by emailing certification@intersystems.com (see below for more details).

A common need for our customers is to configure both HealthShare HealthConnect and IRIS in high availability mode.

It's common for other integration engines on the market to be advertised as having "high availability" configurations, but that's not really true. In general, these solutions work with external databases and therefore, if these are not configured in high availability, when a database crash occurs or the connection to it is lost, the entire integration tool it becomes unusable.

In the case of InterSystems solutions, this problem does not exist, as the database is part and the core

I am trying to finish build for moving to IRIS HealthShare Health Connect 2022.1 from HealthShare Health Connect 2018.1.3. I am currently using Delegated Authentication using an AD group to match up to the Role in IRIS. The Role has access to everything but the HS Resources because we don't really use the HS Resources for anything. We are mainly using IRIS for the Interoperability Engine.

I'm always on the lookout for tools that make the development and testing of my interfaces more efficient. A couple of years ago I came across HL7 Spy, from Inner Harbour Software. It quickly became my go-to tool for running message comparison reports for interface engine migrations, message statistics gathering, and troubleshooting message receipt and delivery. It also offered enhanced functionality for things like fetching messages via sftp that other tools don't provide.

I've recently been working with HL7 Spy's author, Jon Reis, to enable support for fetching messages directly from the Ensemble message store. Its SQL Loader feature now has native Caché/IRIS support, and I've contributed a small server-side class to support the extraction of messages using it.

InterSystems is pleased to announce the 2023.1 release of InterSystems IRIS Data Platform, InterSystems IRIS for Health, HealthShare Health Connect, and InterSystems IRIS Studio are now Generally Available (GA).

2023.1 is an Extended Maintenance (EM) release. Many updates and enhancements have been added in 2023.1.

There are also brand-new capabilities, such as production-ready support for Columnar Storage, ability to use Bulk FHIR, and support to MacOS 13 Ventura. Additionally, a new feature to provide the ability to use Foreign Tables is being released as "experimental" and will be accessible

Overview

Cross-Skilling from IRIS objectScript to Python it becomes clear there are some fascinating differences in syntax.

One of these areas was how Python returns Tuples from a method with automatic unpacking.

Effectively this presents as a method that returns multiple values. What an awesome invention :)

out1, out2 = some_function(in1, in2)

ObjectScript has an alternative approach with ByRef and Output parameters.

Do ##class(some_class).SomeMethod(.inAndOut1, in2, .out2)

Where:

• inAndOut1 is ByRef
• out2 is Output

The leading dot (".") in front of the variable name passes ByRef and for Output.

Hi all,

I'm trying to use LOAD DATA to insert 11k (11,377) rows of data. LOAD BULK DATA is not available for the version of IRIS I am using.

After calling LOAD DATA it says only 5,500 rows has been inserted. The LOAD DATA docs says any error rows are skipped and a count of skipped rows can be found in %SQL_Diag.Result however there are no results here. There are no errors in the xDBC error log either.

Why have over half the rows been skipped?
