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.
 

Hi.

I would like to exchange data with external system every one minute or even more frequent. So I need to trigger production process/operation every minute. How can I do it?

I'm trying to install the Inter System IRIS data platform in windows and I'm not able to download the installer file. Some one can help me with this.

Please look at the below image for the reference for the error I'm facing 

And also I'm looking for the docker version of the IRIS, but here also I'm not able to identify the IMAGE for the same. Please look into the below image.

Thanks.

How do i Install HS.FHIRServer.Installer in InterSystems IRIS?

Is there any way to perfom a cyclick redundancy of a "stream" instead of string?

I know exists the method $ZCRC but I think it's only for strings.

Thank you!

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 testmethod (which doesn't contains any rocke

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 dev

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. Maven also provides tool

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

I have a BPL that I set up a trace to check if the ProcRsltStatus Order is 1. Because the trace is set up in the BPL, I am having issues in searching traces that have the 1 in the message viewer. Any idea how I can limit my search to only the ones with ProcRsltStatus Order::1? Thanks in advance.  

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!

Hello!
I am trying access each "name" tag in the xml-file down below and want to display them through the trace in the production:

Hi,

DBA has asked me to configure a working Business Operation using a SQL.OutboundAdapter (connecting to external MSSQL server) to run as TRANSACTION ISOLATION LEVEL READ UNCOMMITTED.

According to Databricks Apache Parquet is an open source, column-oriented data file format designed for efficient data storage and retrieval. It provides efficient data compression and encoding schemes with enhanced performance to handle complex data in bulk. Apache Parquet is designed to be a common interchange format for both batch and interactive workloads. It is similar to other columnar-storage file formats available in Hadoop, namely RCFile and ORC. (source: https://www.databricks.com/glossary/what-is-parquet). Below are the characteristics and benefits of Parquet according to Databricks

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. I chose the Imagine API. It allows up to 50 free calls per day, and has an interesting paid package that allows you to create thousands

Hello all,

I have downloaded the latest community edition of IRIS and have stood up a vista system with File Manager, Taskman, the RPC Broker  etc up and running just fine on the latest FOIA release. I am trying to eventually connect a JS/React front end to a long-term mumps project of mine via the RPC Broker within my vista instance. I realize there is probably a much easier way to perform CRUD operations in my database via a web app without using the RPC Broker in a Vista instance, but I would like to eventually turn this project into a tool that my dev team could use, so need to do it this

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

I have the following bug

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!

How can IRIS productions be deployed more quickly and with greater peace of mind?

The aim of interoperability productions is to enable you to connect systems in order to transform and route messages between them. To connect systems, you develop, configure, deploy and manage productions that integrate several software systems.

That’s what the InterSystems documentation on its reference website tells us, but what do you actually have to do to deploy a production ?

Productions can be composed to connect external systems to the IRIS Data Platform. To do this, it is necessary to create an enviro

Hello, I am quite new with InterSystems, SAM and Grafana. I am looking a way to get Log Files and Application Errors from InterSystems to SAM like in this post: https://community.intersystems.com/post/grafana-support-intersystems-iris. Is this plugin still under development or is there any other way to get those errors? By using SAM, I do not get those errors.
