In response to the infrastructure needs of our company's service, I've created a small API that sends SNMP queries to InterSystems to visualize relevant data for retrieval when the infrastructure implements monitoring.
However, I'm experiencing a timeout issue when attempting to collect information using an SNMP walk. Here is the code for my API's SNMP service:
New to coding in InterSystems IRIS® data platform? Try this brand-new learning program to get the basics, and see how to develop an application with InterSystems ObjectScript alongside your language of choice: Java, .NET, Python, or Node.js.
I'm using a customised IRIS Community Edition Docker Container: Node.js has been added and the Native API for Node.js directory moved to a node_modules folder in /home/irisowner. I've changed the _SYSTEM password using the Management Portal (which connects to IRIS just fine)
If I shell into the running container and try to connect with a JS script file containing this:
If I test the Native api for Node.js from the documentation, I noticed (if I'm correct) all methods and calls are synchronous. By default due to the nature of Node.js, there is only one thread of execution and normally all JavaScript methods and all calls should be asynchronous and use either a callback function (the "old way") or promises or the async/await contruct to return their result, e.g.:
The concept of low code development is getting more and more important across all industries. Everybody who is starting to get into low code programming, will inevitably come across Node-RED. InterSystems IRIS is renowned for its interoperability and so should be accessible via Node-RED.
I'd like to announce the release of something really rather interesting - revolutionary in fact. That may sound like hyperbole, but I don't think you'll have seen anything quite like this, or even thought it possible!
We've pushed out a new JavaScript/Node.js module named glsdb which you can read all about here in detail:

I am a newbie who is trying to learn how to set up a basic connection to Iris using a node js application. I am astounded at the lack of documentation there is on how to do this and even more concerning there are a few errors within the documentation. For example I am on the Native API application within the below link.
I wrote a step by step tutorial in the qewd-howtos repository how you can write state of the art multi-page web apps with Node.js using a QEWD-Up WebSocket/REST api back-end integrated with a mainstream web framework like NuxtJS & Vue.js.
There's been quite a bit of discussion lately in this forum on the tools available in IRIS for using both XML and JSON, and debate on cross-conversion between the two formats.
I have a Problem with the Session Handling in .csp.
I wrote all my Web Services in .csp-Pages and do the work for example in the OnPreHttp Method for to get some data.
After that the Web Service response is in JSON.
I call These Web Services via fetch in my react Single Page application, also Many request parallel. The react App is Rolled out as index.html. Everything Works Fine with the session Handling via Cookie.

The latest WebComponent-based, SB Admin 2-themed QEWD Monitor application now includes a cool D3-based viewer for visualising your IRIS or Cache Globals - see example below
This qewd-monitor-adminui application is automatically installed when you install QEWD on a Windows machine
See here for details on installing QEWD on Windows:
My attempt to run a node.js command fails at the open command with a "Error loading Cache Library: C:/InterSystems/Cache2018/bin/cache.dll; Error Code 126 (The specified module could not be found.)" result. I can't argue with the error message as the cache.dll file doesn't exist. Apparently I missed an installation step. Could somebody point out what it might be please.
Version: Node.js Adaptor for Cache: Version: 1.1.136a (ABI=48)

Happy new year! I’m Raj Singh, InterSystems’ product manager for Developer Experience and I’d love your feedback on how you use IDEs today and your thoughts for the future.
I am planning to build a WebApp that will have tons of data to display in tables, ability to add comments on that table rows and may be some few more small features as we move on.
1. It has to be Secure
2. It has to be fast
3. It has to be Non CSP / Non Zen
4. Will have Cache DB to pull records from but should be flexible to do that from any odbc resource
5. Version 2018 Ensemble
My first step would have been to investigate different options for technologies that would make it work and best suited with Ensemble 2018
Hot on the heels of the QEWD-JSdb announcement, QEWD-baseline provides a ready-to-run baseline environment for developing REST APIs.
The QEWD-baseline repository (https://github.com/robtweed/qewd-baseline) includes a fully-detailed tutorial on how to build RESY APIs using QEWD and the QEWD-JSdb database (running of course on IRIS).
New from InterSystems Online Learning: two new exercises that help you get hands-on with InterSystems IRIS to see how easy it is to use to solve your problems!
This is the second post on the resources for Developers. This part is about Open Exchange
Using Open Exchange to Learn InterSystems
InterSystems Open Exchange is a applications gallery of tools, connectors, and libraries which InterSystems Developers submit to share the experience, approaches and do business. All the applications are either built with InterSystems data platforms or are intended to use for development with InterSystems data platforms.
If you are a beginner developer you can take a look at applications in Technology Example category. All the applications in this category come with open source code repositories, so you are able to run the samples and examples in a docker container with IRIS on your laptop or in the cloud IRIS sandbox. Examples:
