#InterSystems IRIS

I'm trying to update the hosts file on Windows in C:\Windows\System32\drivers\etc

I know that in Linux if you update the hosts file, you sometimes need to restart the Network Manager for the changes to take effect.

So my question is that is there a similar thing that we need to do on Windows or do the changes take effect as soon as the file is saved?

This is a rather personal view of the history before Caché.
It is in no sense meant to compete with the excellent books from Mike Kadow discussed in an earlier article.
We have different histories and so this is meant to create a different perspective of the past.

Migrating data to another system takes two steps.

1. Migrating class definitions

To migrate the class definition to another system, export it to a file in XML format or UDL format (extension .cls).

The export procedure in Studio is as follows.

Tools > Export

> Select multiple classes you want to migrate with the [Add] button

> Check [Export to local file]

Our team has had success creating and publishing Power BI reports using an ODBC connection to an IRIS database, but there have been concerns about the responsiveness of these reports.

As an attempt to improve responsiveness, I'm trying out the "DirectQuery" connection using the InterSystems IRIS connector available in our version of Power BI Desktop (September 2021).

The version of IRIS I'm connecting with is "IRIS for Windows (x86-64) 2022.2"

Hi Community!

I think everyone keeps the source code of the project in the repository nowadays: Github, GitLab, bitbucket, etc. Same for InterSystems IRIS projects check any on Open Exchange.

What do we do every time when start or continue working with a certain repository with InterSystems Data Platform?

We need a local InterSystems IRIS machine, have the environment for the project set up and the source code imported.

So every developer performs the following:

1. Check out the code from repo
2. Install/Run local IRIS installation
3. Create a new namespace/database for a project
4. Import the code into this new namespace
5. Setup all the rest environment
6. Start/continue coding the project

If you dockerize your repository this steps line could be shortened to this 3 steps:

1. Check out the code from repo
2. Run docker-compose build
3. Start/continue coding the project

Profit - no any hands-on for 3-4-5 steps which could take minutes and bring head ache sometime.

You can dockerize (almost) any your InterSystems repo with a few following steps. Let’s go!

Let's say you have Python including variable-length arguments methods. How can you call it from ObjectScript?

I know that a TCP connection sends back an ACK, but what about REST, SOAP, HTTP, etc..?

Hi *.*,

I am new to IRIS, IKO and IAM. I have read through a lot of the documentation, but I need clarity on some things that I can't find in the documentation.

Hi Developers!

There is a recent update came for developer community images of InterSystems IRIS and IRIS For Health.

This release comes with Environment variables support.

Currently 3 variables are supported:

• IRIS_USERNAME=user to create
• IRIS_PASSWORD=with password
• IRIS_NAMESPACE=create namespace if doesn't exist

Here is what you can do - see below.

Start iris with your username and password created:

docker run --rm --name iris-sql -d -p 9091:1972 -p 9092:52773  -e IRIS_PASSWORD=demo -e IRIS_USERNAME=demo intersystemsdc/iris-community

Git stores complete history - meaning you would never lose your files, even if they are deleted, they are still available. That, however, presents an issue if large or sensitive files have been committed. Deleting them DOES NOT remove them from history. Recently one of the repos I work on became unexpectedly large, so here's how you can resolve that:

Hi Developers!

As you know InterSystems IRIS Interoperability solutions contain different elements of the solution, such as: production, business rule, business process, data transformation, record mapper. And sometimes we can create and modify these elements with UI tools. And of course we need a handy and robust way to source-control the changes made with UI tools.

For a long time this was a manual (export class, element, global, etc) or cumbersome settings procedure, so the saved time with source-control UI automation was competing with lost time to setup and maintain the settings.

Now the problem doesn't exist any more. With two approaches: package first development and usage of IPM package git-source-control by @Timothy Leavitt

The details are below!

I have a %GlobalBinaryStream object that I'm trying to save as a local file after being received through a SOAP Web Service.

To do this, I created a %Stream.FileBinary object and wanted to set where the stream copied to this object would be saved by using either the DefaultStreamDir() ClassMethod or the NewFileName() ClassMethod. However, the documentation isn't very helpful on how to use these ClassMethods.

Right now, I have the below code:

I have a csp page that is using embedded Runtime Expression (https://docs.intersystems.com/ens201817/csp/docbook/Doc.View.cls?KEY=RCS...) and within that expression I am using a $data() modulo 2 to look for root-level data elements (https://docs.intersystems.com/ens201817/csp/docbook/Doc.View.cls?KEY=RCO...).

E.g:

I am trying to write a message to a Kafta cluster programmatically (i.e. not in Ensemble or using a Production) using %External.Messaging. I am consistently getting a 'topic not found error' even though I have created the topic on the cluster. I dug into the client I created an when accessing the property KaftaClient.jclient.gateway I get the following output:
