By specifying the start and end values ​​of the IDs for which you want to rebuild indexes in the arguments of the %BuildIndices() method provided in the persistent class (=table) definition, you can rebuild only the indexes within that range.

For example, to rebuild the NameIDX index and ZipCode index in the Sample.Person class only for ID=10 to 20, execute the following code (the ID range is specified in the 5th and 6th arguments). 

 set status = ##class(Sample.Person).%BuildIndices($LB("NameIDX","ZipCode"),1,,1,10,20) 

$LB() is the $ListBuild() function. The

I'm setting up a web application as CSP/ZEN to host a React SPA. SPA's typically need to use a fallback page to deal with server requests based on the browser route, unless you use hash routing in the browser code. Our requirements prevent us from using hash routing, so we need to deal with 404's - redirecting/fallback them to index.html - a very common practice. I 'think' IRIS uses Apache under the hood, so I tried adding a .htaccess in the applications root directory - which did not work.

I have notified the following :

• Web Gateway usually maintain a certain amount of TCP/IP connections (that is capped to Maximum Connections) with Super server process (also named %SYS.SERVER). Those connections will stay, even after some client requests (eg: browser) have been processed and the TCP/IP connections have been closed the other side (between client and webserver, usually Apache).
• As a consequence, there will be (at minimum) a certain amount of IRIS worker processes waiting for a request to came, which is good (eg: 200 maintained TCP/IP connections = at minimum 200 IRIS worker

Introduction

In some of the last few articles I've talked about types between IRIS and Python, and it is clear that it's not that easy to access objects from one side at another. 

Fortunately, work has already been done to create SQLAlchemy-iris (follow the link to see it on Open Exchange), which makes everything much easier for Python to access IRIS' objects, and I'm going to show the starters for that.

Thank you @Dmitry Maslennikov !

Installing

To install, simply open your terminal with administrators' access and type

pip install sqlalchemy-iris

and that will also install the pre-requisites for

The FHIR® SQL Builder, or Builder, is a component of InterSystems IRIS for Health. It is a sophisticated projection tool used to create custom SQL schemas using data in an InterSystems IRIS for Health FHIR repository without moving the data to a separate SQL repository. The Builder is designed specifically to work with FHIR repositories and multi-model databases in InterSystems IRIS for Health.

The objective of the Builder is to enable data analysts and business intelligence developers to work with FHIR using familiar analytic tools, without having to learn a new query syntax.

Hi there,

I want to use regex in my code, and I saw that the %Regex.Matcher class contains a property "OperationLimit" that you can also set to a number of steps that the regex engine should take maximum in analysing a given string. So far so good.

I tried to set the property with the function OperationLimitSet() to a silly value like 3. In 3 steps only very few regex should be executed, right? But what I found is that my regex always comes up with a solution. Here is what I did:

First I initialised my %Regex.Matcher.

set m = ##class(%Regex.Matcher).%New("(.+)\@(.+)\.(.+)")
do m.OperationLimitSe

In this article, I am demonstrating how to create a table column(formerly known as properties) with your custom datatype classes by using User defined DDL.Properties are the crucial member of the persistent class definition.Datatypes are essential to define types of values that are stored in a table column.In general, the datatype names of SQL different from Intersystems datatypes, such as VARCHAR = %String.you have the ability to create or modify a table by using these datatypes.Indeed, you’re creating the tables through DDL and you have your own datatype classes are already defined.

Hello Community,

To get to my problem, I need to elaborate a bit. We use an older fixed length format called HCM to transfer data from our SAP-ISH system to the Intersystems server. The data file is generated on a dedicated server and stored in a directory that is mounted to the communication server.
The synchrnoization is done via a lock file, which is exclusively locked in the adapter.
Now this, let's call it HCM server, is to be replaced.

Have you ever felt like your PDF files take up too much space on your server? As you collect more and more of these files, you might run into storage issues that can be costly to solve. But what if there was a way to shrink the size of these PDFs by 50% to 70% without compromising the document's visual clarity.

Today, we're going to explore a solution for this problem that I really like: GhostScript.

What is GhostScript?

Ghostscript is a free and open-source software suite that provides a powerful set of tools for compressing documents, including PDFs.

Has anyone tried AWS Batch with InterSystems IRIS docker images?

I have a noninteractive workload (but it requires internet access from the job to deliver results), so I'm considering using it as a simpler alternative to ECS since Fargate backs both, and that's enough for my use case.

I wonder if anyone tried and cares to share the results, issues, cfn templates.

InterSystems Reports version 23.2 is now available from the InterSystems Software Distribution site in the Components section.  They are labeled InterSystems Reports Designer and InterSystems Reports Server and are available for Mac OSX, Windows or Linux.  insightsoftware elected to move from a  numerical number plan to a year-based numbering plan in 2023 so there are no versions 20 through 22;  versions increase from Version 19 to Version 23.  Note that the reports Server docker image will be available at a later date from the Container Repository.

This new release brings along some great

I'm looking for an efficient way in DBeaver to filter system tables (ex: belonging to a schema starting with "%").

By using a user with the %All role, DBeaver shows us a long list of system schemas, which forces us to go down the list before accessing the user tables.

Wanted to share something I learned recently while working on a problem. We needed to add and change some Business Hosts in one of our edge productions.

In the past, we simply added the production class to CCR and then spreading it around. But there was a problem because different developers were working on different things, and we only wanted to include only the relevent production changes onto the CCR. 

Here's a little piece of code that can help add new things to an existing production:

class HSEDGE1PKG.ProductionDefinition
{

/// define the Productions Definitions which are listed below/

I have a problem. Occasionally, I am getting locked out of IRIS because of password failures. However, the failures aren't necessarily related to my password.  We are using VSCode, and I have installed one or two proposed APIs for use with the software (because that's just how I am; I want to learn the new stuff).

Today, I had that problem again. The step that caused the problem was most likely when I was trying to switch the branch I was using and updating within VSCode. Let's say I was switching from branch "1A" to branch "2B". When I did this, IRIS caught two password errors:

You can see the

I am trying to create the JSON message below for a REST API:

Class REST.Test.Sample.ItemDetails Extends (%Persistent, %JSON.Adaptor)
{

Property ItemId As %String;

Property Item As list Of AllItems;

}

Class AllItems:

Class REST.Test.Sample.AllItems Extends (%JSON.Adaptor, Ens.Response)
{Property ItemtId As %String;

Property itemName As %String(MAXLEN = 100);

Property itemStockNumber As %String(MAXLEN = 150);

Property itemType As %String;

Property itemPriority As %String;

Property itemDetailData As %String(MAXLEN = 10000);
}

I have a table with the data I want to export as a JSON message containing a list

When creating the db using the Properties array, if I use a literal like "/iris/db/<instance name>/<directoryname>" it's created in the correct directory.

       set Properties("Directory")="/iris/db/InstanceName/DirectoryName"

but when it's executed with a variable, as in the example below,  it gets created in /iris/sys/<instance name>/mgr/

      set directoryPath="/iris/db/InstanceName/DirectoryName"
      set Properties("Directory")=directoryPath

 Is there any reason string literals work and variables do not?

We continue with the series of articles based on the QuinielaML application.

In today's article I will describe how to work with the Embedded Python functionality available in InterSystems products.

Embedded Python allows us to use Python as a programming language within our productions, being able to take advantage of all the features available in Python. Here you can expand information about it.

First of all, let's remember what the designer of the architecture of our project is like:

Get hands-on with SQL Search, a tool in InterSystems IRIS® data platform that allows you to quickly search large amounts of unstructured text data stored in SQL tables (exercise, 15m).

We have a customer with a production used to manage DICOM messages and they are asking us about de StorageLocation configuration. The question is:

Is there a way inside IRIS to define a purge over the folder used as StorageLocation?

Before we start talking about databases and different data models that exist, first we'd better talk about what a database is and how to use it.

A database is an organized collection of data stored and accessed electronically. It is used to store and retrieve structured, semi-structured, or raw data which is often related to a theme or activity.

At the heart of every database lies at least one model used to describe its data. And depending on the model it is based on, a database may have slightly different characteristics and store different types of data.

To write, retrieve, modify, sort, transform or print the information from the database, a software called Database Management System (DBMS) is used.

The size, capacity, and performance of databases and their respective DBMS have increased by several orders of magnitude. It has been made possible by technological advances in various areas, such as processors, computer memory, computer storage, and computer networks. In general, the development of database technology can be divided into four generations based on the data models or structure: navigational, relational, object and post-relational.

Hi !

I'm looking for a simple way to store in a string a list in $lb representation.  Ex : 

Set list = $ListBuild("data2", "data2", "data3")
ZWrite list
/* show : list=$lb("data1","data2","data3") */

With the ZWrite command, we can display the $lb representation but I would like to store it in a string variable.

Trying to write multiple records to a file via Record Mapper from a single inbound DFT transaction with multiple FT1 segments. DTL with HL7 DFT inbound and Record Mapper outbound checks field values in both FT1 segment and PV1 segment within a "foreach" loop, and if criteria are met for a particular FT1 then the target fields in the record map are set with values from multiple segments (MSH, PID, PV1, and FT1).

Is there a best practice to set the memory options (classic xms and xmx) on the JavaGw service in the production?

What can be recommended?

Like specifying 1024M for xmx is for a single process? that process can't grow beyond that value right? what happen if the process reach the memory limit?

Thanks
