Question Iryna Mykhailova · Nov 9, 2022

Hi guys!

My student asked my why his unit tests don't work as they should, and I just could answer him. Here is the simplified case.

There is a class with a required unique property Name:

ClassPropertyAs

And there is an inherited class:

%Persistent

What I expect to happen, is when I save two objects of class  with the same value of property Name, for the second one to get an error stating that it violates the unique index.

 ##class

 Right now, it saves both objects without any problems. And there's no index global as well.

Question Evgeny Shvarov · Apr 9, 2023

Hi folks!

When I launch IRIS as a docker container instance, e.g. like this one:

docker run --name iris-sql -d --publish 9091:1972 --publish 9092:52773 intersystemsdc/iris-community

And then try to connect to it e.g. via irissqlcli it says I need to change the password:

irissqlcli iris://_SYSTEM:SYS@localhost:9091/USER

Password change required

I know that I can open Management portal http://localhost:9092/csp/sys/UtilHome.csp and change password manually, but is there a programmatic way?

Say if I have a password in a file and I can just provide it to docker instance for the change?

I have a persistent class (GetOrgUpdatesResponse) that has a property which is a list of another persistent class (Organization).

What would be the best way to cascade deletes so that on deletion of a parent row each object in the list property is then also deleted? 

I have included a sample of my classes here for clarity

ClassExtends%PersistentAs

Where Organization is defined as the following class

Question Chris Marais · Jun 28, 2022

I have followed the Article: Continuous Delivery of your InterSystems solution using GitLab, On our own Linux environment it works well but when I try to run it on a clients windows server; and the following command is run by the runner

irissession IRISHEALTH -U TEST "##class(isc.git.GitLab).load()" 

we get the following "error"

<NOTOPEN>>

I do not know why this happens, it does look like it has something to do with user rights but I am totally lost at this point as we have done everything I can think off relating to grant correct access etc.

Question Norman W. Freeman · Aug 14, 2024

I use the following code to loop trough all globals : 

set""for

However this is really slow : about 1second per node. 

I ran debugger, and it seems most of the time is spend in "%SYS.GD Visible" function. There is a comment that says : 
"Sees if globals in dataset are visible to our namespace"
This function loop on a global named  ^mtemp which contains lot of records (10K or more).
I have cleared global, hoping it has been filled by another process but it's not (it seems to be filled by %SYS.GD)

Why is it so slow, Is there a way to make this faster ?

Question Igor Barboza · Aug 15, 2024

Hello every one, here in our company we are trying to develop a tool to help us in our "Code Review" that today is completely done for another developer.
So I need to develope a tool that reads a class/routine (Already done) and identify if in the current line there is some abbreviated command, that is against our policy of codification, for example:
s variable = "test"
d ..SomeMethod()

Question Sukhpreet Singh · Jul 15, 2023

I have created a global say ^myglobal and entered some data. I am storing the name of global in databases and fetching the name based on some criteria. I am getting "^myglobal" in return from databases but i am not able to fetch the data I stored in the global. 

I tried set var = result.global which gives me "^myglobal" in var. Doing WRITE var will return "^myglobal" and not the data i stored in this global.

Question Aya Ayuk · May 3, 2023

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.

Question Sylvain Guilbaud · Aug 23, 2023

Is it planned that LOAD DATA takes into account several DATE/DATETIME formats with, for example, a parameter indicating the format used in the source data?

example :

LOAD DATA .../...
USING
{
  "from": {
    "file": {
       "dateformat": "DD/MM/YYYY"

Question omer · Oct 1, 2024

Hello everyone, 
so lets say i have the following:

Hello
Q
say(arg)
    w arg
 Q


and i am trying to execute it by its name such as:


s a = "say^hello"

*execute the name inside a*
 

now I know for a fact that if say were written without any argument then do @a would work!

but I can I pass an argument in this case?
I don't want to use Xecute because I am in need of really high performance code.

I am trying to help another group within our organization access a SQL Table that I have created to populate Epic Department Data within our environment and came across the ability to use SQL Seach REST Interface using iKnow.

However, I am having issues trying to get it to work via POSTMAN before I hand off the solution...

the POST URL... https://<servername>/api/iKnow/latest/TESTCLIN/table/osuwmc_Epic_Clarity.DepartmentMaster/search

where osuwmc_Epic_Clarity.DepartmentMaster is the table

Question Phillip Wu · Feb 13, 2023

Hi,

I have a IRIS mirror set

. all running on SUSE Linux

. each on a separate server

consisting of

Primary

Backup

Arbiter

My arbiter is the ISCagent.

Question

=======

Is there a Linux command showing me the status of the ISCagent as arbiter?

The systemctl service command below shows if the service is running but not if it is acting correctly as an arbiter.

I'm looking for a command like iris list which you can run on the Primary or Backup

===

systemctl list-units --type=service|grep -i isc
ISCAgent.

Question Anderson Negreli · Mar 3

I am currently managing environments running InterSystems IRIS and Caché on Windows servers.

I’m reviewing storage optimization best practices and I have a question regarding a specific Windows drive setting: "Allow files on this drive to have contents indexed in addition to file properties."

Based on my research, everything indicates that it is better to disable this option, especially on drives used by databases. However, I couldn't find a specific "official" stance in the documentation explicitly mentioning this checkbox.

 Hello, good afternoon! (or good morning or good evening)
 

I was doing some very basic tests, based on the documentation, using Python in Studio.
I decided to call a python method through the Studio's own terminal as a demonstration, but the result was different from the terminal result:
Code:

Class// Write ##class(User.EmbeddedPython).Test()/// Description

Hi everyone, 

today I'm asking your help with an issue related to the response messages sent from my production to a client software, such as Postman or SoapUI. 

Issue

In the last few days I've been unable to view the responses received from my production in Postman, even if I was able to do so earlier. I'm sending the request to a remote server reachable via a Putty tunnel.

Postman Test

I'm currently testing this simple POST message:

Question Pietro Di Leo · Jun 21, 2025

Hi everyone,

I'm preparing to move to a new PC soon and I'm trying to migrate the server connections I use in IRIS Studio to the new environment.

I’ve followed without success an old procedure I've found on a post on the community that involves exporting the registry key from:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Intersystems\Cache\Servers

But I’ve realized that this only includes the entries from the Server Manager and not the actual server connections used within IRIS Studio and shown within the "Server Connections" menu.

Question Scott Roth · Jan 18, 2024

I had a question about using ZSTART, ZSTOP, and ZMIRROR.

  • If we use them and it is not correct, does it mess up with any of the existing functionality?
  • So, if I create a ZSTART with a simple command of starting the %JDBC Server will that mess up anything existing in the Startup sequence?
  • Is ZSTART, ZSTOP, and ZMIRROR just an extension of the existing functionality, or does it alter how the built in functionality runs?
  • Should we tread lightly in the use of them?

Question Thomas Wuppermann · Jul 3, 2025

Hi,

sometimes we need more then one Iris container at the same time. Since as containers they always have the same instance name shown in the management portal, it is hard to distinguish the management-portals of the instances. Searching for a way to make it easier I thought I could change the instance name shown in the management portal. I tried "iris rename" in different ways but could only change the configuration name which is shown by "iris list", not the name in the management portal.
