InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

In the WRC, we often see customers contact us because they are having been provided a .PPK file for use with SFTP connections, but they don’t know how to use that key within InterSystems IRIS. This article will explain why this represents such a problem, and explain how to use the .PPK key to generate a Private / Public Key pair in a format recognized by InterSystems IRIS.

Killer presentations are essential for opening doors, doing business and delighting customers. These types of presentations move away from the traditional and tiring topics and portions of texts, or even pictures of happy people to get closer to the interests of their audience.The best presentations materialize what customers are looking for into something they can see working. Instead of promises, examples in execution and the ability to be very close to what you want to do.

Work Queue Manager (WQM) is a feature of InterSystems IRIS that enables you to improve performance by distributing work to multiple concurrent processes programmatically. The idea is that you split the work into chunks, and WQM distributes the chunks across worker processes and can provide the info that the work is done.

However, recently, I got an interesting question: there's a large logical transaction composed of ~1,000,000 individual objects and SQL inserts and updates. Some updates are CPU-intensive, so the original idea was to use WQM to split an update into chunks to speed things up.

But, here's a catch: if one of the individual 1,000,000 changes fails (there's a variety of application-level checks so that it can fail, and that's not even that abnormal a behavior), the entire transaction must be rolled back. That creates a problem: each chunk must report success before committing their individual transactions, and someone must get all these reports and decide if we are committing or not.

Unfortunately, it looks like WQM does not have a bidirectional communication between workers and manager, so I suggested an approach using events:

  1. Start jobs.
  2. Wait for all jobs to report success using $System.Event.WaitMsg().
  3. Send Commit or Rollback using the $System.Event.Signal().

The IKO allows for sidecars. The idea behind them is to have direct access to a specific instance of IRIS. If we have mirrored data nodes, the web gateway will (correctly) only give us access to the primary node. But perhaps we need access to a specific instance. The sidecar is the solution.

Building on the example from the previous article, we introduce the sidecar by using a mirrored data node and of course arbiter.

Hi,

I have an odd problem that occurs when I'm trying to import lookup tables in the XML format into Studio.

I store my files in in C:\CodeRepository.

I can manually import these lookup tables using "Import local..." option in the InterSystems Studio.

However, when I'm trying to import them using command in terminal: do $system.OBJ.LoadDir("C:\CodeRepository\","ck")

I'm getting the following error:

  • The idea of this package is to compare the performance of columnar storage inside IRIS without wrapping it to some foreign platform that is not my world
  • In addition, I do not want to measure network performance between 2 containers, but inside a closed IRIS environment that I have fully under my control
  • Even the use of SMP or some other browser-based presentation has some influence that I want to avoid.

I had a question about using ZSTART, ZSTOP, and ZMIRROR.

  • If we use them and it is not correct, does it mess up with any of the existing functionality?
  • So, if I create a ZSTART with a simple command of starting the %JDBC Server will that mess up anything existing in the Startup sequence?
  • Is ZSTART, ZSTOP, and ZMIRROR just an extension of the existing functionality, or does it alter how the built in functionality runs?
  • Should we tread lightly in the use of them?

If you are a customer of the new InterSystems IRIS® Cloud SQL and InterSystems IRIS® Cloud IntegratedML® cloud offerings and want access to the metrics of your deployments and send them to your own Observability platform, here is a quick and dirty way to get it done by sending the metrics to Google Cloud Platform Monitoring (formerly StackDriver).

We now get to make use of the IKO.

Below we define the environment we will be creating via a Custom Resource Definition (CRD). It lets us define something outside the realm of what the Kubernetes standard knows (this is objects such as your pods, services, persistent volumes (and claims), configmaps, secrets, and lots more). We are building a new kind of object, an IrisCluster object.

How to send the HL7 Batch messages over a SOAP webservice which takes 3 credentials(Username, Password& Org.ID) using IRIS Management Portal V 2019.1?

WSDL xsd : element - 1.Username , 2.Password ,3.Org.ID ,4.HL7 Message.

Info I had -

Source is CSV File will be translated to HL7 using data Transformations. All the transformed messages need to be sent to destination System through SOAP request as a single Batch File.

Hi all,

Does anybody have the same issue?

$ZF(-100) to run python script not work when directly execute in studio or in storedproc called by TrakCare, but can work when do in iris session.

The python script imports a "barcode" package. It seems that when directly execute in studio or in storedproc called by TrakCare, the package can not be imported.

Hi all,

As you know, it is very complicated to debug a Business Service Rest API because the object is created when the applications receive a request, so we cannot have the JobId that we can use to debug.

https://docs.intersystems.com/iris20211/csp/docbook/DocBook.UI.Page.cls?...

So, I'm trying to get the JobId when the class is being created, write a trace in OnInit() method and write the JobId in a log info

A Tutorial On WebSockets

Intro

Most server-client communication on the web is based on a request and response structure. The client sends a request to the server and the server responds to this request. The WebSocket protocol provides a two-way channel of communication between a server and client, allowing servers to send messages to clients without first receiving a request. For more information on the WebSocket protocol and its implementation in InterSystems IRIS, see the links below.

VIP in Azure

If you're running IRIS in a mirrored configuration for HA in Azure, the question of providing a Mirror VIP (Virtual IP) becomes relevant. Virtual IP offers a way for downstream systems to interact with IRIS using one IP address. Even when a failover happens, downstream systems can reconnect to the same IP address and continue working.

The main issue, when deploying to Azure, is that an IRIS VIP has a requirement of IRIS being essentially a network admin, per the docs.

To get HA, IRIS mirror members must be deployed to different availability zones in one subnet (which is possible in Azure as subnets can span several zones). One of the solutions might be load balancers, but they, of course, cost extra, and you need to administrate them.

In this article, I would like to provide a way to configure a Mirror VIP without the using Load Balancers suggested in most other Azure reference architectures.
