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. 

Class CDM.OrderResultMsg Extends Ens.

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?

I am looking for any examples on hoe to use http request to connect to S3, list buckets and loop thru them to download files recursively.

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?

Regards

Hi folks, 

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

CREATEFUNCTIONIN

I know that a FUNCTION can only return one result. But it seems that the PROCEDURE can return several values and then in theory it should work as in the example above

https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cl…

Can you tell me how this can be implemented? Then it would be very convenient to generate test data

Hi,

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

Thanks for suggestions.

thanks

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.
I`ve created an app:

Also here is a dispatcher class:
 

ClassExtends%CSP.REST0

But when I call the Get method: http://localhost:52773/csp/crud/hello
There is an error: 403 Forbidden
I don't understand what can cause it.

Hey Developers,

Start watching the new video on InterSystems Developers YouTube:

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?

Hey Community,

It's time to announce the winners of the InterSystems Java Contest 2023! 

Thank you to all our amazing participants who submitted 13 applications 🔥 

Welcome everybody!

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.

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.

In the sample code below, a list of class definitions is obtained using the query Summary of the class %Dictionary.ClassDefinitionQuery.

ClassClassMethod#dim

An example of execution is as follows.

Hello all,

I am trying to start java gateway and constantly getting an error in terminal:
"%RemoteService+3^%Net.Remote.Gateway.1 *%Exception.StatusException ERROR #5023: Remote Gateway Error: TCP error on port '55555', ensure there is an Object Gateway running on this port". I've checked jvm and it is running properly, telnet also is able to connect to the port.

Has anyone encountered this issue before?

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.

Hi Guys,

I have a client posting me JSNON file using a Get action and I'm using the below code to retrieve the data:

Class SX3.Production.HTTP.GetPSRequest Extends Ens.BusinessService [ ClassType = "", ProcedureBlock ]
{ Parameter ADAPTER = "EnsLib.HTTP.InboundAdapter"; Method OnProcessInput(pInput As %CharacterStream, Output pOutput As %CharacterStream) As %Status
{
    Set pOutput=##class(%GlobalCharacterStream).%New()
    Set tSC=##class(Ens.Util.JSON).ObjectToJSONStream(pInput,.tJsonPayload,"aceloqs")
    set jsonString = tJsonPayload.

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 

GetImplicitEndpoint

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

Thanks

Scott

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?
