#InterSystems IRIS for Health

How many times do we find ourselves rebuilding, copy-pasting, adapting, Business Operations that make calls to REST services, and only adapting one or another part of the final code. This is annoying a lot. To resolve this our inconvenience, I present to you Interopway REST, a set of classes (a micro framework) that allows us to just add Business Operation to Production and use it.

The project is hosted on github, https://github.com/cristianojs/interopway_rest, it is open and we are accepting collaborations.

Let's understand how this works.

Hi,

I'm trying out VS Code with IRIS for Health 2023.2 (not available in above dropdown) in a local container.  I can open read-only files in the Objectscript viewer and have a local folder connected to the correct namespace.  However, when I make changes and try the "import and compile" option, I get:

ERROR #16006: Document <filepath> name is invalid

The first four chars of <filepath> appear to have been truncated

Here is my settings.json

{

    "security.workspace.trust.untrustedFiles": "open",

    "workbench.colorTheme": "InterSystems Default Dark",

    "intersystems.

Methods written in ObjectScript can use pass-by-reference arguments to return information to the caller. Python doesn’t support pass-by-reference arguments, so Embedded Python in IRIS doesn’t support them either. That's it, that's the end of the post, hope you liked it. 😉 But wait, what about the Classic Rock & Roll?

Actually, since returning values in method arguments can be useful, this post demonstrates several ways to do this, between ObjectScript and Embedded Python.

Hi,
i'm working with an instance of IRIS that does a lot of integration (HS) and i need to schedule all the cleaning jobs for the productions.

Is there a way to "clone" the purge task for all the namespaces?

Have just deployed IRIS in Azure and when accessing the filesystem through SSH I just can't see the ISC folder through the WSL ubuntu user, what am I missing here?

As I want to create new folders and use the same in test productions.
the needed directories are created in /home/azureuser but the same is not visible in IRIS file system

Example:

Method Execute (args...) As %Status {
...
 #dim statement as %SQL.Statement
 set statement = ##class(%SQL.Statement).%New(2)
 set statement.%Dialect = "CACHE"
 do statement.prepare(query)
    
 #dim rs as %SQL.StatementResult
 set rs = statement.execute(args...)

My questions are: 1) how do I get the size of **args **2) how to get all values of **args **3) is it possible to modify the args?

We are very eager to learn what kind of feedback you might have for InterSystems.

We hope you had a chance to download and install one of the kits that show how the new process works. If not, you still can do it, following the instructions on these posts:

Our target release is InterSystems IRIS 2023.2 (and InterSystems IRIS for Health 2023.2) and will be available in a few months.

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.

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.

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!

Hey Developers,

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.

Project configuration:

Let us begin! We have published the entire application in OpenExchange so that you only need to download and deploy it in Docker as you can read in the associated README file.

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.

InterSystems FAQ rubric

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.

EHR (Electronic Health Record) systems are modeled in a proprietary format/structure and are not based on market models such as FHIR or HL7. Some of these systems can interoperate data in a proprietary format for FHIR and other market models, but others can not. InterSystems has two platforms that can interoperate proprietary formats for market ones: InterSystems HealthShare Connect and InterSystems IRIS for Health.

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

John

Hi all,

I am trying to start the production after creating the business components in code, but I don't seem to be able to do so

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.
