Intro

In a fast-paced digital era, effective communication is crucial. This article introduces a Java-based chat project, combining the strength of IRIS database and ChatGPT intelligence. Built on Java, it goes beyond real-time messaging, leveraging IRIS and ChatGPT for an enhanced chat experience. Also, the name of the project references the cultural classic - Star Wars.

Building Application

Building our dynamic chat application involves a seamless integration of key components and technologies.

Case description

Let’s imagine that you are a Python developer or have a well-trained team specialized in Python, but the deadline you got to analyze some data in IRIS is tight. Of course, InterSystems offers many tools for all kinds of analyses and treatments. However, in the given scenario, it is better to get the job done using the good old Pandas and leave the IRIS for another time.
    For the abovementioned situation and many other cases, you might want to fetch tables from IRIS to manage data outside InterSystems’ products.

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

Hi, Community!

This article is an overview of SQLAlchemy, so let's begin!

SQLAlchemy is the Python SQL toolkit that serves as a bridge between your Python code and the relational database system of your choice. Created by Michael Bayer, it is currently available as an open-source library under the MIT License. SQLAlchemy supports a wide range of database systems, including PostgreSQL, MySQL, SQLite, Oracle, and Microsoft SQL Server, making it versatile and adaptable to different project requirements.

The SQLAlchemy SQL Toolkit and Object Relational Mapper from a comprehensive set of tools for working with databases and Python. It has several distinct areas of functionality which you can use individually or in various combinations. The major components are illustrated below, with component dependencies organized into layers:

I want to connect the app to Cloud SQL but when I registered and created the deployment (trial) I got the error:

Did anybody face such an error?
During the creation of an account, there was a message like 'username is taken' but the account have been created anyway. Maybe it could cause this problem.

Question Julius Kavay · Nov 23, 2023

I'm in a very early phase of an project where some of the methods should be written in python. Occasionally, projects also have byproducts, I call them utility methods, because some of the methods the project uses can also be used in other applications too. I tend to put such methods in percent classes, so they can be used everywhere, independent of the namespace, where an application runs. I try to do the same in my current project  too, merely with python it doesn't works! Why?

The question is, what is wrong with the (%Zpy.Utility) class below?

My newest app includes a java routine to read data from Excel 95, 97, 2000, XP, and 2003 workbooks and write the data into IRIS globals using Java Native API library.

If you have Git and Docker installed, clone/git pull the repo into any local directory

$ git clone https://github.com/oliverwilms/excel-java-iris.git

Open the terminal in this directory and run:

Question Yone Moreno · Nov 28, 2023

Hello,

First of all thanks for your help, time, and answers.

We would like to know what are we doing wrong and how could we improve it and fix it.

We need to convert the Api Monitor Metrics which are a String with this format:

iris_cache_efficiency 13449.122
iris_cpu_pct{id="CSPDMN"} 0
iris_cpu_pct{id="ECPWorker"} 0

[...]

iris_wdwij_time 11
iris_wd_write_time 8
iris_wij_writes_per_sec 0

To JSON.

We would expect them to look like a normal JSON as follows:

{
"iris_cache_efficiency": "13449.122",
"iris_cpu_pct{id='CSPDMN'}": "0",

[...]
"iris_wij_writes_per_sec": 0
}

We have currently developed a REST Operation

K9s is a terminal-based UI (aka kubectl clown suit), to manage Kubernetes clusters that drastically simplifies navigating, observing, and managing your applications in K8s, including Custom Resources like the InterSystems Kubernetes Operator (IKO) and ArgoCD Applications. If you are about to take your CKD, CKA, or CKS, leave k9s well enough alone for awhile as the abstraction to kubectl will become the standard for navigating the cluster and you will undoubtedly become estranged to the extended flags of kubectl and bomb the exam.

Maven Projects mixing ObjectScript and Java

What is Maven?

Maven is a tool, hosted by the Apache Software Foundation, for building and managing any Java-based project. Apache Maven is the best source of information.

Why Maven?

Managing a project, its dependencies, and life cycle can be a tedious task. Maven automates these tasks, making project management much simpler. Maven also defines a standard directory layout and provides tools for initializing projects. These tools employ project templates called maven archetypes. There is a rich library of archetypes available.

Question Enrico Parisi · Sep 2, 2022

I'm converting a .NET gateway interface (call .NET code from IRIS) from the old "Caché style" that use imported proxy class to the new $system.external .NET gateway as documented in:

https://docs.intersystems.com/iris20221/csp/docbook/DocBook.UI.Page.cls…

For simple case it works and I'm fine, unfortunately I don't understand how to implement/access .NET arrays from IRIS and unfortunately the documentation has no info whatsoever on how to work with arrays.

What I'm looking for is how to implement the same code as described in the old .NET gateway

Hi community!

In this article, I'm excited to introduce my latest application, Journal File Indexer. The development of this application is rooted in the portal idea  DPI-I-270.  

In short, this application lets you load and index a log file in a database.  

Why?

If you've ever used the log file search function in the management portal, you may have encountered a timeout error or even a blank page. This problem usually occurs when searching a large journal file. Journal File Indexer solves this problem by considerably increasing the speed of searches once the file has been loaded into the database.  

Another problem arises during the restoration process. When searching for global entries in a log file to restore old or new values, the management portal doesn't have this specific functionality. A routine must therefore be coded to achieve this. Journal File Indexer comes to the rescue, incorporating a restore function!

Currently, many digital artists use generative AI technology as a support to accelerate the delivery of their work. Nowadays it is possible to generate a corresponding image from a text sentence. There are several market solutions for this, including some available to be used through APIs. See some at this link: https://www.analyticsvidhya.com/blog/2023/08/ai-image-generators/.

I created a new application to use in IRIS taking advantage of one of these APIs.

Hi,

I'm receiving in one of our interface a XML file as a %Stream.GlobalBinary, and in the source Application that produces this XML file, the user sometimes add a special character that force the XML file to have the header encoding to UTF-8, instead of ISO-8859-1 : 
<?xml version="1.0" encoding="UTF8"?> 

When my current interface tries to convert the %Stream.GlobalBinary into %XML.XPATH.Document to this exceptional UTF8 header encoding of the XML file : 

Set tSC=##class(%XML.XPATH.Document).CreateFromStream(stream,.tDoc)  --> contains exceptionally UTF8 encoding

While starting the development with IRIS we have a distribution kit or in case of Docker we are pulling the docker image and then often we need to initialize it and setup the development environment. We might need to create databases, namespaces, turn on/off some services, create resources. We often need to import code and data into IRIS instance and run some custom code to init the solution.

And there plenty of templates on Open Exchange where we suggest how to init REST, Interoperability, Analytics, Fullstack and many other templates with ObjectScript. What if we want to use only Python to setup the development environment for Embedded Python project with IRIS?

So, the recent release of Embedded Python template is the pure python boilerplate that could be a starting point for developers that build python projects with no need to use and learn ObjectScript. This article expresses how this template could be used to initialize IRIS. Here we go!
