Hi community members!

I'm testing some functionalities about Foreign Tables and it works smoothly with PostgreSQL database, but I found out an issue with MySQL database, I followed the documentation:

• Step 1: I've created my SQL Gateway connection to my MySQL database: **WARNING** if the name of the driver file is too long IRIS won't be able to get it.

when doing ETL process from cache database to mysql database(ods) and to another mysql database(dwd).

There are  lots of DR columns in one table.

In the first step we need two databases to be totally consistent(ods=cache database)

However, the DR column in another database lost its meaning and become to normal number.

In the last step we do the data governance in ODS to DWD. My question is how to write sql without many `join` in this step.

Hi all.

Recently, I have noticed Scott Roth's mission to resolve issues with Orphaned messages with a lot of focus on prevention, and I envy that level of dedication.

Not wanting to be left out, this has sparked an interest in checking my environments for orphaned messages. Amongst a few different posts on the subject, I came across this post from Suriya Murugan in 2016 that included an interesting class in a Github Gist that seems to be built to do a deep dive into the identification and cleanup of Orphaned Messages.

Hello Community,

As per the Build index documentation "If you use BUILD INDEX on a live system, the index is temporarily labeled as notselectable, meaning that queries cannot use the index while it is being built. Note that this will impact the performance of queries that use the index." Is this  hiding/not selectable is only applicable for BUILD INDEX or it supports class level %BuildIndices as well. as far as my analysis both syntax setting this setting SetMapSelectability. 

Thanks!

Hello community, first of all, apologies if anyone was offended by the blasphemy 😔

Have you ever thought it would be interesting to have the source code separated from the database data? Perhaps you'd like to be able to back up your code without copying gigabytes of client data.

Below, I'll explain the steps to separate your sea formed by the source code and data into two different databases within a namespace.

Hi,

I'm very new to InterSystems  Health Connect so may be doing something silly...

I'm trying to link to an Oracle DB view using the Link Table Wizard in the Management Portal. The wizard finds the view, but when I select it and click the 'next' button I get an error on the 'Select Columns' screen: 'ERROR #5534: Columns error' (and no columns show in the wizard). I've tried on several views and tables in the same DB but keep hitting the same error.

I have previously successfully mapped a view and table from the same DB and am not sure what I am doing differently. Any suggestions appreciated!

Data for InterSystems products (table row data, object instance data) is stored in global variables.
The data size of each global can be obtained by clicking the properties of the global you want to view from the Management Portal > System > Configuration > Local Database > Globals page, and then clicking the Calculate Size button on the Global Attributes page that appears.
To display the data sizes of globals in a namespace, you can call ^%GSIZE utility on the terminal.
The method of execution is as follows.

Hello Community,

I have encountered the following SQL problem trying to create a table from a SELECT statement.

I narrowed the problem down to the following example:

1. The SELECT statement alone works as expected.

SELECT m.Name, h.Status 
FROM EnsLib_HL7.Message m, Ens.MessageHeader h 
WHERE h.MessageBodyClassName='EnsLib.HL7.Message' AND h.MessageBodyID = m.ID

2. But if "CREATE TABLE ... AS" is added it fails

CREATE TABLE UKEr.Test AS
SELECT m.Name, h.Status
FROM EnsLib_HL7.Message m, Ens.MessageHeader h
WHERE h.MessageBodyClassName='EnsLib.HL7.Message' AND h.MessageBodyID = m.ID

Hi,

We are developing a .NET6 application using Iris database. We would like to use ORM for easier code maintenance. 

I saw a doc about Entity Framework: https://docs.intersystems.com/iris20231/csp/docbook/DocBook.UI.Page.cls?KEY=BNET_eframe, but even it's newest Iris version, the Entity Framework is very old .NET Framework (2013) and not supported by Microsoft anymore. Are there any plans to support Entity Framework Core?

Data Analysis

This is the sequel to Data Collection. If you have not had a chance to go through and install that you should first do that.

What is provided here is the analysis for the collection of that data that was collected earlier.

In much the same way as was done in that repository you will need to import the xml that makes up this repository.

Starting at the topmost level there is a task:

InvestigateInfoTask

This task will allow us to set parameters that we will be monitoring. They are as follows:

GrowthPercentageWarning: What percentage growth is 'acceptable' for a global to grow.

Graphical Display of Tables

Here we will document how you can get the results of your Data Collection to be displayed graphically. The output of your project will look like this:

Note that I am working on a local machine. If you are doing this on a server then be aware to use the correct IP address.

First, we will import the three classes from the that we are going to need (note that we will edit them later):

You can take the xml and import it to your system.

Data Collection

This is a step-by-step instruction guide for creating a task to collect data about the InterSystems database and globals therein (as seen in the associated Open Exchange App - find all the associated code there)

UPDATE (Aug 1 2024): Recently I've been asked about the differences between this and the History Monitor functionality. In short, the data collection monitor builds on the history monitor by adding the ability to track growth of individual globals.

Introduction

Hi Community,

I'm looking for someone who has already made data ingestion into IRIS (or Caché) from Pentaho Data Integration.

Thanks in advance.

Hi. In a project I'm involved in I need to connect to a MongoDB database, read some data and store it in some internal table. 

I'm wondering what's the best way to connect to MongoDB, as it seams to me there's no native Intersystems adapter.

Did anyone have handled such a scenario?

Thank you. Best regards

Hi guys,

I'm trying find a way to create a row with the number of each row.

For example:

In the SQL above, i want a way to create a collum with the number of corresponding row, in this case:

1

2

3

In SQl SERVER i can use FOR, RANK or ROM_NUMBER to do this, but, i can't find a way to do the same in cache SQL.

Can someone help me?

Thank you.

hi there,

I recently created a shell script to run the integrity check.

I used this as reference - Introduction | InterSystems IRIS Data Platform 2023.3

I found the example from above url having a line - "

kill ^IRIS.TempIntegrityOutput(+$job)

it isn't working when I used in a script. it returns the pid of my iris session instead.

I had to simplify the example to run following lines instead - 

Do CheckList^Integrity(,,,,5)
do Display^Integrity(,1,)
 

script runs fine and can see integrity check results as expected.

Hi Community,

What is the correct syntax in a merge.cpf file to create a database with its associated resource ?

The InterSystems IRIS has a series of facilitators to capture, persist, interoperate, and generate analytical information from data in XML format. This article will demonstrate how to do the following:

1. Capture XML (via a file in our example);
2. Process the data captured in interoperability;
3. Persist XML in persistent entities/tables;
4. Create analytical views for the captured XML data.

Capture XML data

The InterSystems IRIS has many built-in adapters to capture data, including the next ones:

Hey everyone,

I'm currently running into a very weird issue to where I am trying to connect with a 64 bit version of SQL Server Management Studio (SSMS) to a HealthShare instance. I have created a System DSN using the Drivers (image below) that were downloaded with the Client version of the install and I'm able to successfully connect using my credentials.

Spoilers: Daily Integrity Checks are not only a best practice, but they also provide a snapshot of global sizes and density. 
Update 2024-04-16:  As of IRIS 2024.1, Many of the below utilities now offer a mode to estimate the size with <2% error on average with orders of magnitude improvements in performance and IO requirements. I continue to urge regular Integrity Checks, however there are situations where more urgent answers are needed.

I am currently adding a field to our Existing messaging from Epic, however there might be a possibility I need to back load data into the Ancillary system. While I have the previous messages that can be sent, they do not have this additional field that I am adding to the message.

I can do a lookup against Epic Clarity SQL Database; however, I don't want to throw a wrench into the workflow if the system cannot connect to the Epic Clarity SQL Database.

What is Unstructured Data?
Unstructured data refers to information lacking a predefined data model or organization. In contrast to structured data found in databases with clear structures (e.g., tables and fields), unstructured data lacks a fixed schema. This type of data includes text, images, videos, audio files, social media posts, emails, and more.

Why Are Insights from Unstructured Data Important?
According to an IDC (International Data Corporation) report, 80% of worldwide data is projected to be unstructured by 2025, posing a significant concern for 95% of businesses. Forbes Article

What is Kubernetes?

Kubernetes is an open-source container orchestration framework developed by Google. In essence, it controls container speed and helps you manage applications consisting of multiple containers. Additionally, it allows you to operate them in different environments, e.g., physical machines, virtual machines, Cloud environments, or even hybrid deployment environments.

What problems does it solve?

Hello everyone,
I searched but didn't find anything. Could you tell me if the IRIS database has any class that natively works with blockchains?

I have some databases in my cache instance that were created from an online backup file (.cbk). I would like to see the information for these databases in the Databases and SQL sections of Management Portal, but they only appear in the Classes section. I can navigate to the files in my cache instance terminal and see the CACHE.DAT files, and a check in the terminal shows that they are mounted.This is what I see in the terminal for each database when I check to see if the databases are mounted:%SYS>set db="/path/for/mydatabase"%SYS>w ##class(SYS.Database).%OpenId(db).Mounted

Hi community,

We have a developed a new version of a production, all the code is new and has changed BP. This application load information for some brands and stored in database.

The customer wants to implement the changes only for some brands because he wants to check for small brands before to implement for all brands.

My proposal is create a new namespace, with the new code, and disabled all load of brands except the brand that he wants to check.

I'm wondering what is the best way to clone the namespace.

Hello, community!

Ihave been tinkering around with Flutter lately and, as a result, came up with some apps that can use Firebase as a database. When I realized there was an available Python library, I felt the urge to create something for InterSystems IRIS that would communicate with the Firebase RealTime Database and perform CRUD operations. Later, I stumbled upon the following idea from Evgeny in the portal:

https://ideas.intersystems.com/ideas/DP-I-146 

That is when  I got down to work!

Are you curious to see my findings? Then buckle up because we’re about to take off!

It seems like yesterday when we did a small project in Java to test the performance of IRIS, PostgreSQL and MySQL (you can review the article we wrote back in June at the end of this article). If you remember, IRIS was superior to PostgreSQL and clearly superior to MySQL in insertions, with no big difference in queries.

Well, shortly after @Dmitry Maslennikov told me "Why don't you test it from a Python project?" Well, here is the Python version of the tests we previously performed using the JDBC connections.
