InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

Has anyone had success with passing in a collections property within a SOAP request to a Soap Service in Ensemble? Please reply with how you set up that collections property. I am able to successfully send a SOAP request correctly containing the elements of the collection property to Cache, as seen in a custom soap log file which I am using to troubleshoot. But the collection property in the Ensemble request is not getting serialized, meaning MyContainers has nothing.

My.Request consists of a property, MyContainers, which can have 0 or more Containers (My.Container)

If I had:
________________________________________
Class MN.Student Extends %Persistent
{
Property Name As %String;
________________________________________
Class MN.Course Extends %Persistent
{
Property TeacherName As %String;
Relationship StudentName As MN.Student [ Cardinality = one, Inverse = Name ];
________________________________________

For "Cardinality = one" the SQL line below would be sufficient for archiving
INSERT INTO MN.Course (TeacherName, StudentName) VALUES ('Pierre','3')"

Hi Everyone,

I tried to send the Sample XML from Packet Sender to Intersystems IRIS TCP Inbound adapter for learning purpose.

You can use the system routine ^DBSIZE to estimate the backup file size (see also Note 1).

^DBSIZE estimates the file size of full, cumulative, and differential backups of the databases selected in the database backup list.

The database backup list is created from [System Administration] > [Configuration] > [Database Backup] > [Database Backup List] in the Management Portal.

Several steps should be done in order to secure the connection through xDBC clients to an IRIS Server instance using TLS. Most of the information can be obtained from the documentation about TLS on IRIS here, about configuring the security layer for encrypted connections. In the next paragraphs we will cover an step-by-step guide on how to configure and test the connection using SQL Clients apps using ODBC and JDBC.

InterSystems is committed to providing a high quality developer experience including a great IDE (Integrated Developer Experience). For the past several years we have been evolving Visual Studio Code's ObjectScript tooling in parallel with our long-standing IDE, InterSystems Studio. There have been over 46,000 downloads of the VSCode-ObjectScript plugin, and the feedback from developers is that this is a great developer experience, and now superior to InterSystems Studio.

Welcome, dear members of the community!

In this article we are going to demonstrate the great potential that IRIS/HealthConnect makes available to all its users with the use of Embedded Python and we are going to do it by developing a small production that will allow us to recognize and identify the faces present in a JPG file from some images that we will use as a reference.

I did some experiments on my local machine and found out that IRIS seems to associate each request (eg: CSP request) to a dedicated process named IrisDB.exe

This process has 3 threads, and one of them seems to be the main working thread (that will the handle request).

If I spawn many concurrent requests, the number of IrisDB processes on my local machine will grow (to make sure each request can be handled in parallel).

It seems there is a limit : it will create no more than 64 processes to handle requests (eg: even if 100 concurrent requests are send to IRIS).

ZLANGC0* functionality

Hi,

I use ZLANGC00 and ZLANGC01 for shortcuts at programmer level to some frequently used dev tools. Is there a way to pass 2 arguments to a command?

Example:

ZZQD "Queue1" // Equivalent to D ZZQD^%ZZLANGC00("Queue1") to display messages in queue1 (ZZQD is my own code in %ZZLANGC00)

but if I wanted to type ZZQD "Queue1" $H-3 to call ZZQD^%ZLANGC00("Queue1",$H-3) can it be done or do I need to write something to manipulate the argument? So ZZQD "Queue1-3"

I'm using the EnumerateJobStatus query of class Ens.Util.Statistics to obtain the LastActivity value of a Business Host.

I would expect that this would return the timestamp of the last message received by the BH, understanding that any connect/disconnect activity would reset that timer. However, the time returned appears to actually be the time at which Ens.MonitorService generated the alert and is not directly related to anything that happened in the BH itself.

Hello, I need to determine the best way to split a class containing multiple methods(about 20), into multiple classes in which each method is in its own class. I am wondering if there is another way other than manually creating the different classes, and copying each method into each class. Doing this in Intersystems Studio.

Hello everyone!
Maybe someone will tell me what could be the reason for such messages in the message.log file

Programming and languages

Being a programmer nowadays is basically the geek version of being a polyglot. Of course, most of us here, in the InterSystems Community, “speak ObjectScript”. Howeever, I believe this wasn’t the first language for many people. For instance, I had never heard about it prior to getting the appropriate training at Innovatium.

I'm trying to update the hosts file on Windows in C:\Windows\System32\drivers\etc

I know that in Linux if you update the hosts file, you sometimes need to restart the Network Manager for the changes to take effect.

So my question is that is there a similar thing that we need to do on Windows or do the changes take effect as soon as the file is saved?

Hi experts

I'm trying to configure an IRIS ODBC connection with "Windows NT authentication using the network login ID". I have created the System DSN as below:

and user (PROD\test) in the SQL Gateway connection

However, as the error message suggests, IRIS is trying to connect with PROD\svc_mist, rather than PROD\test configured above.

Migrating data to another system takes two steps.

1. Migrating class definitions

To migrate the class definition to another system, export it to a file in XML format or UDL format (extension .cls).

The export procedure in Studio is as follows.

Tools > Export

> Select multiple classes you want to migrate with the [Add] button

> Check [Export to local file]

Our team has had success creating and publishing Power BI reports using an ODBC connection to an IRIS database, but there have been concerns about the responsiveness of these reports.

As an attempt to improve responsiveness, I'm trying out the "DirectQuery" connection using the InterSystems IRIS connector available in our version of Power BI Desktop (September 2021).

The version of IRIS I'm connecting with is "IRIS for Windows (x86-64) 2022.2"
