Integrating frontend React applications with backend services like IRIS database via REST APIs can be a powerful way to build robust web applications. However, one common hurdle developers often encounter is the Cross-Origin Resource Sharing (CORS) issue, which can prevent the frontend from accessing resources on the backend due to security restrictions enforced by web browsers. In this article, we'll explore how to tackle CORS issues when integrating React web apps with IRIS backend services.

what is the purpose of default settings in System management portal?

Given a properly formatted ISO 8601 date time of 2024-06-23T06:03:00Z using SQL DatePart results in an error:

[SQLCODE: <-400>:<Fatal error occurred>]

[%msg: <Invalid input to DATEPART() function: datepart='ss', datetime value='2024-06-23T06:03:00Z')>]

If I remove the trailing Z (for Zulu / UTC time) and leave the T, DatePart works fine.

Hi everyone,

We have successfully configured the Patient Index and are now looking to bring it to upper environments. Our plan is to export the Linkage Definition and import it into higher environments to avoid any manual work. However, I am having trouble finding an export option in the Linkage Definition Designer and locating the globals that hold this setup.

I would greatly appreciate any tips or guidance on how to export/import the Patient Index configuration between environments.

Thank you in advance!

I'm trying to keep all writes in local memory.

If you have S %A="""HI THERE"",!,#,33.33,"" "",$ZTIMESTAMP"

and you O 2 U 2 W @%A C 2 ZW ^SPOOL
^SPOOL(1,1)="HI THERE"_$c(13,10)
^SPOOL(1,2)=$c(13,12)
^SPOOL(1,3)="33.33 67016,59246.6188873"

It works just fine and the output is in the ^SPOOL global.

However, I'm trying to avoid writing to disk.

I can't find anything besides using the SPOOL device that will allow the use of the "@" indirection.

I need to be able to take the size of the request from a given %CSP.request

however it seems the best the docs suggest is to get the length of characters in the request (using $order and Get, Count)...
this is not good enough for what I need to do, Any suggestions?
I scanned the docs and couldn't find anything.

I am working on JSON and want to be prepared to handle large Objects. I try this code:

ClassMethod MaxLen() As %Status

{

set longStr=""

for i=1:1:$SYSTEM.SYS.MaxLocalLength() { set longStr = longStr_"x" }

write "Maximum string length = "_$LENGTH(longStr)

;

set longObject = {"a":(longStr),"b":(longStr)}

set file=##class(%File).%New("/tmp/longObjectFile.txt")

do file.Open("WSN")

do longObject.%ToJSON(file)

do file.Close()

;

do file.Open("RS")

HI,

I'm migration an existing integration to InterSystems. The upstream (external) system calls a JSON web service hosted in the interface engine, which converts the JSON data received to an HL-7 messages to send to the downstream system. I'm looking for direction and example of how to do the equivalent in InterSystems, so the the upstream system only has to modify the URL of the web service they call.

I suppose in IS we'll need to create a business service that is a JSON web service? How to access the JSON data (parameters in the web service call) in the Transformation?

Hi,

I would like to ask whether there is some option to stop auto-formatting when I compile. The code is sometimes well formatted but the auto-formatter does not work correctly in some situations. I am talking about the compilation in the Studio editor in this image, not about Visual Studio Code.

Thank you in advance,

Alin C Soare.

Hello,

Recently I have been tinkering with VSCode and ObjectScript extension to connect to my dockerized IRIS instance. I have configured the instance to use Apache as a Web Gateway as per instructions and it has been working well. Currently I'm using a self-signed certificate for the SSL part of the connection. The browser nags about insecure certs when connecting to Management Portal but that's expected.

However when I try to connect to the instance with VSCode it simply fails with the following error message

I am trying to extract GMHeap, Locksiz values form Config.config using python (imported irisnative for Python) but the below python progam is not returning any value. Please suggest if i am doing any mistake -

Also, plese suggest how i can set values for GMHeap and Locksiz to a different value through Python.

import irisnative

A new source is sending us CCDs with templates in the structuredBody section that are either just being ignored or being saved in the wrong data type. Ex notes being saved under the Encounters fields. We would like to use the Notes.xsl (out-of-the-box) to transform a certain template section into a Document SDA. Could you tell me how that can be accomplished?
