InterSystems FAQ rubric

If you want to run an OS executable file, command, or a program created within an InterSystems product when the InterSystems product starts, write the processing in the SYSTEM^%ZSTART routine. (The %ZSTART routine is created in the %SYS namespace).

Before you write any code in SYSTEM^%ZSTART, make sure that it works properly under all conditions.

If the ^%ZSTART routine is written incorrectly, or if it is written correctly but the command does not return a response or an error occurs during processing, InterSystems products may not be able to start.

Hi:

We are looking again into DB size. Looking at our Ens.MessageHeaderI GSIZE is 3767107

Looking at the global i'm not sure if we have had an issue in the past so much of the data looks the same, we only have 3 values in the  $zwc and although some of the data in the $c between 1 and 18630 it looks very similar as if there was an issue in the past. But if anyone has any examples of their index param this would help to know if our global is abnormal. 

Data below 

^EnsLib.H.MessageI("Extent",18631)	=	$zwc(152,8000)/*$bit(1..64000)*/
^EnsLib.H.MessageI("Extent",20750)	=	$zwc(152,8000)/*$bit(1

I'm having problems with an HL7 message that is not properly parsed by IRIS (any version, including Ensemble).

The message is a OML_O21 and is valid, in fact is similar of what is described in the document "IHE Laboratory Technical Framework, Volume 2a (LAB TF-2a) version 6.0".
This is the sample from the IHE document (paragraph 2315):

MSH|^~\&|OF|Chemistry|AM|Automation|200309060825||OML^O21^OML_O21|msgOF101|T|2.

Hi, I am trying to optimize a method, I am only occasionally receiving Internal Server Error from GUI interaction and when viewing the Application Error Log in IRISHealth this is what I see. <UNDEFINED>%0Ac+3^%sqlcq.QM.uEgYAnxQ4duxnAiaOpZgvilz1tlo.1 *sqldata15d : CSP Error .

I have no idea how to read this and pinpoint the issue.

Full details below.

Hi Community,

⏯ Introduction to HealthShare Unified Care Record

I have a table that is already created and contains data.  I need to create a unique constraint that is a combination of two fields. Is there a way to do this in a SQL statement?  Also, I would lke to know how to add it in the table class.

Hello,

First of all thanks for your help.

We have the following scenario: some responses include special characters as ">" and "<" which are being put inside a property defined as:

Property PACPROBLEMAS As %String(MAXLEN = "", XMLNAME = "PAC_PROBLEMAS");

So then, when we observe the LOG SOAP it shows that the Target System replies to the ESB as follows:

➡️ <PAC_PROBLEMAS>46807#278.

Hello Community,

I have encountered the following SQL problem trying to create a table from a SELECT statement.

I narrowed the problem down to the following example:

1. The SELECT statement alone works as expected.

SELECT m.Name, h.Status 
FROM EnsLib_HL7.Message m, Ens.MessageHeader h 
WHERE h.MessageBodyClassName='EnsLib.HL7.Message' AND h.MessageBodyID = m.ID

2. But if "CREATE TABLE ... AS" is added it fails

CREATE TABLE UKEr.Test AS
SELECT m.Name, h.Status
FROM EnsLib_HL7.Message m, Ens.MessageHeader h
WHERE h.MessageBodyClassName='EnsLib.HL7.Message' AND h.

Dear Community, 

Is there any way to search , select and abort a specific set of messages from a large queue in Healthshare business operation? 

Thank you for your help

I have an API that does not have all the data.  Like it is truncated. Magic number of characters seems to be 163,280

I do an <assign> 

context.RawBundle=##class(%DynamicObject).%FromJSON(context.FHIRResponse.Body)

The error does not happen when the response is < 163,280 chars.  And when < 163,280 chars, it is a complete FHIR Bundle.  Have anyone experienced this?  If so, what is the resolution?

I created a FHIR Client to execute a GET response from an external FHIR server. I set everything up according to this post: https://community.intersystems.com/post/create-fhir-rest-client#comment…

I was able to send a GET request and got a response of type HS.FHIRServer.Interop.Response.

But in the visual trace, I do not see the actual json response payload.  I opened the response object in terminal and saw it has a QuickStreamId, which I used with the HS.SDA3.QuickStream class to open the quickstream object. But how do I get the payload from this quickstream object? 

I was trying to interact through IRIS terminal by giving user id and password from command-prompt, but iris terminal command is not recognizing. Please suggest how i can interact with iris terminal here. 

iris terminal <instance name> -U <user id> -P <password> not working

Please note i am new to IRIS. 

Can any one tell me the difference between %KillExtent and %DeleteExtent with example

For some time I have been planning to do some type of proof of concept with the Workflow functionality, which, like so many other functionalities present in IRIS, tends to go quite unnoticed by our clients (and for which I say mea culpa). That's why I decided a few days ago to develop an example of how to configure and exploit this functionality by connecting it with a user interface developed in Angular.

To avoid a very long article and make it more accessible, I am going to divide it into 3.

Hi Community,

Finally and with a little delay, we conclude this series of articles about our Workflow Engine by showing an example of the connection that we could make from a mobile application.

In the previous article we showed the example that we were going to discuss, an application that allows detailed control of a chronic pathology such as hypertension for both the patient and their associated doctor.

Hello Everyone,

The Certification Team of InterSystems Learning Services is developing an InterSystems ObjectScript Specialist certification exam, and we are reaching out to our community for feedback that will help us evaluate and establish the contents of this exam.  Please note that this is one of two exams being developed to replace our InterSystems IRIS Core Solutions Developer exam. You can find more details about our InterSystems IRIS Developer Professional exam here.

How do I provide my input? Complete our Job Task Analysis (JTA) survey!

After upgrading we had 2 major problems with the new version:

- Resending messages adds blank lines.
Because we have many HL7 processes, we regulary have to resend messages if there is an outage of a server we connect with.

- IIS recycling causes webgateway connection problems, after change from PWS to IIS.
At unexpected times a connection can no longer be made.
The strange thing is that it does not occur with every recycle of the application pool.
Setting the password again in csp.ini usually works, but not always, which is of course a major problem.

Hello IRIS Community,

InterSystems Certification is developing a certification exam for InterSystems IRIS SQL specialists, and if you match the exam candidate description given below, we would like you to beta test the exam. The exam will be available for beta testing on June 9 - 12, 2024 at InterSystems Global Summit 2024, but only for Summit registrants (visit this page to learn more about Certification at GS24). Beta testing will open for all other interested beta testers on June 24, 2024. However, interested beta testers should sign up now by emailing certification@intersystems.com (please let us know if you will be beta testing at Global Summit or in our online proctored environment). The beta testing must be completed by August 2, 2024.

I am trying to work with the FHIR Object Model where I convert an incoming  HL7v2 to SDA then FHIR. From here I would like to be able to process the FHIR Object by deserializing it to a Bundle object using the following code my problem is I keep on getting an error  which is not explaining much about what is wrong with what I am doing any help will be appreciated  thanks.

Property FHIRAdapter As HS.JSON.AdaptorFHIR;

Method OnRequest(pRequest As HS.Message.FHIR.Request, Output pResponse As HS.Message.FHIR.Response) As %Status
{

             set pmReqFHIRobj=##class(HS.FHIR.Model.Resource.Bundle).

Data Analysis

This is the sequel to Data Collection. If you have not had a chance to go through and install that you should first do that.

What is provided here is the analysis for the collection of that data that was collected earlier.

In much the same way as was done in that repository you will need to import the xml that makes up this repository.

Starting at the topmost level there is a task:

InvestigateInfoTask

This task will allow us to set parameters that we will be monitoring. They are as follows:

GrowthPercentageWarning: What percentage growth is 'acceptable' for a global to grow.

Graphical Display of Tables

Here we will document how you can get the results of your Data Collection to be displayed graphically. The output of your project will look like this:

Note that I am working on a local machine. If you are doing this on a server then be aware to use the correct IP address.

First, we will import the three classes from the that we are going to need (note that we will edit them later):

You can take the xml and import it to your system.

The spec will actually create the dispatch class and implementation template.

Hi Community,

Watch this video to see how HL7® FHIR® Implementation Guides allow you to restrict or extend APIs, resources, and terminologies:

⏯ What are HL7 FHIR Implementation Guides

New in version 2023.3 (of InterSystems IRIS for Health) is a capability to perform FHIR profile-based validation.

 (*)

In this article I'll provide a basic overview of this capability.

If FHIR is important to you, you should definitely try out this new feature, so read on.

Beginning with the release of InterSystems IRIS® data platform 2022.3, InterSystems corrected the license enforcement mechanism to include REST and SOAP requests. Due to this change, environments with non-core-based licenses that use REST or SOAP may experience greater license utilization after upgrading. To determine if this advisory applies to your InterSystems license, follow the instructions in the FAQ linked below.

This table summarizes the enforcement:

InterSystems FAQ rubric

To disable the timeout, set the query timeout to disabled in the DSN settings:

Windows Control Panel > Administrative Tools > Data Sources (ODBC) > System DSN configuration

If you check Disable query timeout, the timeout will be disabled.

If you want to change it on the application side, you can set it at the ODBC API level.

Set the SQL_ATTR_QUERY_TIMEOUT attribute when calling the ODBC SQLSetStmtAttr function before connecting to the data source.

I am attempting to make a FHIR call against the Epic Repository through Intersystems. I have setup a Service client per Create FHIR REST Client | InterSystems Developer Community | Business

but I have set it up using OAuth and HTTPS.

I have verified that the OAuth works by executing it manually via a Terminal to verify I get a response. Of course, when I do it is writing to the ISCLOG

I am trying to now test making the FHIR call by initiating the test of HS.FHIRServer.Interop.HTTPOperation, however I keep getting mixed results with first a 404 not found error, and now a 401 unauthorized error.
