Hello,

I have created a service in Node.js which interacts with IRIS using APIs. The current implementation uses basic auth. I want to implement OAuth 2, to make the communication between the node.js service and IRIS secure. I want my service to act as client and IRIS as Authorization and Resource server. I don't know how to do that. Anyone who has implemented OAuth using IRIS can you help me out or point me in the right direction on about how to implement it? 

Thank you for your help :)

Hi Community, 

We are trying to filter message created using custom xml class in a business rule.  

HL7 ORU Result messages are converted to custom xml messages with a list properties .Result ORU converted to OrderResultMsg , which contains property Orders as list of Order which contains ResultStatus .  Please see below the class extract.  We are trying to access the ResultStatus property to filter non-final results via business rule.

I am often asked by customers, vendors or internal teams to explain CPU capacity planning for large production databases running on VMware vSphere.

This post was originally written in 2017, I am updating the post in February 2026.For context I have kept the original post, but highlighted changes.This post was originally written for ESXi 6.0.The core principles remain valid for vSphere 7.x and 8.x, though there have been improvements to vNUMA handling, CPU scheduling (particularly for AMD EPYC), and CPU Hot Add compatibility with vNUMA in vSphere 8.

I am trying to run the CSP server. But I get the error:

It worked once, but when I made some changes is displayed an error.
Also, a WEB page looks like this:

Did you face this issue? What is the reason for it?

hi there,when object export to xml,i know that,it will call propertynameLogicalToXSD method,but i can`t find out that use %XML.Reader to parse XML to object  witch method will be called before ,

simple code like this:

Class Samples.NewClass2 Extends (%Persistent,, %XML.Adaptor)
{
Property OPDT As %Library.DateTime;
}

my xml is 

<NewClass2><OPDT>2023-11-30 11:07:02</OPDT></NewClass2>

and how parse it to object ,and not modify the xml?

Hi,

We recently updated Ensemble, on our Unix DEV server , from version 2013.x to 2015.2.3 (Build 855U) and when we test our SSL/TLS configuration we get the following error:

ERROR #729: Certificate /qmd/ens_chldev_1/mgr/SILCert/SILCSSSJR-CER.cer is not valid for TLS Web client authentication .

The certificate was working fine before the update in DEV and it is working fine in our PROD Unix server with Ensemble 2012.x.  Any ideas why we are getting this error?

Hi folks, 

I made a solution (https://openexchange.intersystems.com/package/iris-pretty-gpt-1) and want to use it like 

CREATEFUNCTION ChatGpt(INpromptVARCHAR)
RETURNSVARCHARPROCEDURELANGUAGE OBJECTSCRIPT
{
    return ##class(dc.irisprettygpt.main).prompt(prompt)
}


CREATETABLE people (
nameVARCHAR(255),
city VARCHAR(255),
age INT(11)
)


INSERTINTO people ChatGpt("Make a json file with 100 lines of structure [{'name':'%name%', 'age':'%age%', 'city':'%city%'}]")

I know that a FUNCTION can only return one result.

Hi,

        What is the alternative for INTERSECT in cache. I tried Intersect but not working.

Thanks for suggestions.

What changes are to be made while customizing a FHIR server package when adding a new field. As provided in the documentation, we have a sample JSON package of favorite color and it is added in the table, but when we are adding a new field 'Insurance', it does not imports the package and says package already exists. We have three files of JSON 

1) Package.JSON

2) SearchParameter.JSON

3) StructureDefination.JSON 

What should we have to change for adding new field.

I create a class, property OPDT as %Library.DateTime,the class extends %XML.Adaptor，after run " d obj.XMLExportToString(.xml)" OPDT`s value is 2023-11-28T13:57:26,but what i need is 2023-11-28 13:57:26,so is there any solution?

I restore the “dirty” copy of the IRIS.DAT files, then apply the incremental backup as documented for Online Backup. As shown in the picture, restarting the service before mounting and rejoining the database to the mirror can restore the mirror database to the point in time of dirty data. I think the mount method used here is the default value, and I don't want it to perform mirrorcatchup. Is there any other way to recover the mirrored database to the point in time of dirty data？

I need to create a simple REST application.

Here we are again with an article related to the Mirror!

In the previous article we saw how we could configure a Mirror between two IRIS instances, one acting as an active node and the other as a passive one. This mirroring system works on the transfer of a journal file that keeps the instance that works as a passive node continuously updated, but what happens if due to some communication failure or permissions of the journal file it is not transferred correctly?

The most common is that in this situation our Mirror remains unconfigured, in such a way that the passive node does not receive the

In this short article I would like to present an example of use that surely many of you who work with IRIS as the backend for your web applications have faced on more than one occasion and it is how to send a file to your server from the frontend.

Generally the simplest way I have found to perform this task is to transform the file from the frontend to the Base64 format and make a POST call to our server attaching the Base64 obtained to a JSON message in which I indicate in a parameter the name of the file and in another the encoded data. Something similar to this:

{

Class definitions created by users are stored in class definition classes. They can be used to obtain a list of class definitions from a program.

Note: Class definition classes refer to all classes contained in the %Dictionary package.

I am attempting to setup my first OAuth2 client, as we are adventuring into the realm of making FHIR API calls to our EMR from HealthShare Health Connect. 

I have gone through and set up the Issuer Endpoint, and Client Configuration but now I want to test it and verify that the setup is correct. When I setup the Client Configuration, it would not allow me to use Discovery as it was saying I needed a "Client secret" but was not given one. So I set it up manually, thinking I hit all the information correctly.

However, if I go through the documentation and use GetAuthorizationCodeEndpoint, I am

Trying to setup my first OAuth 2 client to authenticate against Epic's Interconnect instance that is hosting FHIR/Web Service API's. Epic's documentation says the JWT request has to be sent as a POST request..

Does 

GetAuthorizationCodeEndpoint

and

automatically put the request into a POST request, or do I need to format a %Net.HttpRequest to POST?

Thanks

Hi Community, 

Can I please check if any one is aware of any functionality in HealthShare to verify NHS Number check digit.

We are trying to implement the NHS Number check digit validation using Modulus 11 Algorithm ( described here : NHS NUMBER (datadictionary.nhs.uk) ) 

I wanted to check if there is any built in option available or if anyone has implemented something similar using Object Script. 

Thank you for your help.

I made a custom application metric, imported it to the USER namespace and used:

set status = ##class(SYS.Monitor.SAM.Config).Add.ApplicationClass("historymonitor.errorSensor", "USER")

to add it. When I do 'w status' it returns 1 so it is added but I still can't see the custom metric in the api/monitor/metrics endpoint. Even though I added %DB_USER in the application roles for api/monitor.

Does anyone know where the problem might be that the metrics endpoint still doesn't show my metric?
