#InterSystems IRIS

Hey Developers,

Watch this video to learn how to use Embedded Python using applications from the Open Exchange app gallery:

The part II you will learn how to run any Jasper report file (jrxml file) designed on Jasper Studio from InterSystems IRIS. We will create a REST API to return a processed report on PDF format.

The jrxml file

On part I, we designed this report:

1. First of all, rename the report from Blank_A4.jrxml to sample.jrxml (Project Explorer tab > click right the file > Rename):

IRIS can use a KMS (Key Managment Service) as of release 2023.3. Intersystems documentation is a good resource on KMS implementation but does not go into details of the KMS set up on the system, nor provide an easily followable example of how one might set this up for basic testing.

The purpose of this article is to supplement the docs with a brief explanation of KMS, an example of its use in IRIS, and notes for setup of a testing system on AWS EC2 RedHat Linux system using the AWS KMS. It is assumed in this document that the reader/implementor already has access/knowledge to set up an AWS EC2 Linux system running IRIS (2023.3 or later), and that they have proper authority to access the AWS KMS and AWS IAM (for creating roles and polices), or that they will be able to get this access either on their own or via their organizations Security contact in charge of their AWS access.

Hi folks!

Often, when we develop commercial solutions, there is a necessity to deploy solutions without source code, e.g., in order to preserve the IP.

One of the ways how this can be achieved is to use InterSystems Package Manager.

Here I asked Midjourney to paint an intellectual property of software:

How this can be achieved with IPM?

In fact, this is very simple; just add the Deploy="true" clause in the Resource element in your module.xml manifest. Documentation.

I decided to provide the simplest possible example to illustrate how it works and also to give you a development environment template to let start building and deploying your own modules without source code. He we go!

Our objective

In the last article, we talked about a few starters for Django. We learned how to begin the project, ensure we have all the requisites, and make a CRUD. However, today we are going a little further.
Sometimes we need to access more complex methods, so today, we will connect IRIS to a Python environment, build a few functions and display them on a webpage. It will be similar to the last discussion, but further enough for you to make something new, even though not enough to feel lost.

InterSystems FAQ rubric

To run an online backup from a command you can use the API BACKUP^DBACK routine.
An example of performing a full backup is as follows.

It can be retrieved using the schema INFORMATION_SCHEMA.

INFORMATION_SCHEMA is a system schema and is not displayed by default in the SQL menu of the Management Portal.

The method to display it is as follows.

1. Open Management Portal → System Explorer → SQL menu.
2. Check "System" on the left of the schema drop-down.
3. Select INFORMATION_SCHEMA from the schema dropdown.

When executing OS commands, use $ZF(-100).

Let's have a round of Code Golf!

String rotation is when you take a word and move some of its letters to the end of the word, so the first letter becomes the second letter, the second letter becomes the third, and so on. Last letter becomes first. Rotation can happen only in one direction →.
Your task is to write a method that will receive two strings. It then must return an integer value of how many times needed to rotate the strings to be equal.
As usual shortest solution wins.

Let's do a round of code golf! Last one was very popular!

InterSystems FAQ rubric

This error occurs when an instance of the class is already open at compile time.

There are two ways to deal with this issue:

1. Terminate the process or application that has the instance open
2. Compile options in the studio build menu: Check the compile flag “Compile classes in use” and compile.

If you want to determine which process is using the class, try the sample routine below.

On Linux, use the iris command to execute a routine or method from a shell and get the return value.

For more information, please refer to the document "About Instance Connections".

An example of a command is as follows.

Have you ever thought of creating your own systems for editing users or, perhaps, even an API that you can call?

Welcome back to %SYS! If you read the first article in this series, you must have already seen how to manage your users through the Security.Users class programmatically. Today, we will move on to Resources! Many of the classes in this package use a very similar set of methods.
