How do I run a CSP page from within VS Code.

Secondly I have installed an extension called "Live Server" which will run .html pages within VS Code. Have any of you made use of this extension and if so can you specify that .csp pages are html pages?

If I press F5 in VS Code (just as you would in Cache Studio) in order to view a csp page when I press F5 in vs code it tries to open


without the csp page name

I'm trying to set up an Apache server using CSP Gateway on Windows 10 (64-bit), but am getting the error "Cannot load c:/InterSystems/IRIS_2019/CSP/bin/CSPa24.dll into server: %1 is not a valid Win32 application" when attempting to start up httpd.exe after adding the CSP-specific section to httpd.conf.

The CSP gateway is 64-bit (CSPGateway-2018.1.1.643.0-win_x64) and so is the Apache install (httpd-2.4.38-o102q-x64-vc14).

The CSPa24.dll file does exist in the specified location.

Any suggestions appreciated.

Thank you,

Timeout for $zf

In one of the projects, when we have ECP with 10 ECP application servers, from time to time we faced the issue when our journals fail to purge, due to open transactions. While we have about 100-150 GB journal files per day, it quite quickly became a big issue, and with mirroring a very big issue. Mostly we just rebooted our ECP Data server, so it searches rollbacks any transactions, but such process is too long, may steal a few hours. I did not find any way, how to get the list of the open transactions from one place from ECP Data Server. We just migrated our Data server to 2018.1.

I am taking the 'Creating an InterSystems Class Definition' course, and the Exercices asks to open a Terminal from the Management Portal to create and interact with a new object. I didn't found how to acces tot the Terminal from the Management Portal, and the documentation I have seen doesn't help me... sad

10000 clients simultaneously

How InterSystems solutions handle C10k connections? ( https://en.wikipedia.org/wiki/C10k_problem )
For example, I want to create a social network on InterSystems platform.
In the scenario client (browser) => CSP Gateway => Cache can the Cache handle a large number of clients at the same time?
Quick analysis shows that CSP Gateway for each request opens a new TCP connection to Cache SuperServer (port 1972) allocating CSP session and license slot.

I'm trying to export a XML stream containing some files that are supposed to have been written using UTF-8, but I'm facing some broken encoding issues.
You can see below that I'm indeed viewing a UTF-8 encoded and which is inside the CSP folder and encoded correctly (although displaying it on Studio would not display it correctly as the file is not using BOM and that's intentional).

OAuth server to be deployed on the IRIS learning cloud platform. Clients - one on the other instance of the learning IRIS server, the other client locally on my computer in the container docker.

Both clients get a seemingly correct link (through ##class(%SYS.OAuth2.Authorization).GetAuthorizationCodeEndpoint()) to the login request form:

Good evening Intersystems Community,

I want to participate in the Advent of Code 2020 and followed the installation instructions in "The Advent of Code 2020 contest ObjectScript template" (https://openexchange.intersystems.com/package/aoc2020-objectscript-template).

Unforunately I get "Error: Invalid Community Edition license, may have exceeded core limit." at the step "docker-compose build".

You probably have a similar experience.
The more I use Atelier the more I miss INSPECTOR that I had in Studio!

First for PROPERTIES that can inherit a variable number of Parameters beyond imagination.
take %XML.Adapter as the most obvious.
Where to find all inherited methods that I eventually want to overload? Take %Persistent as example.

Or where or how can %OnBeforeAddToSaveSet() (the correct camel case) be overloaded ?

I want to access a Stored Procedure in a remote SQL Server Database. I am quite new to Object script.

The stored procedure has 3 parameters: 2 datetime parameters and 1 integer.

Which is the best way to do that? I'm wondering if I can use the link stored procedure feature inside object script or some SQL statement in Object Script.

This SP returns a set of rows which I want to read, transform and save in a persistent class.

Thanks in advance,

I wonder why IRIS seems to have its on way to deal with order or operations such as the example in the title. This affects regular arithmetic operations but of course conditions in various statements.

Even after years of COS development, I still get caught by these tiny frustrating details and it is absolutely annoying when you are writing APIs that some some maths.

Here is an example:

VSCode and CSP - what did I miss?

Hi -

I'm trying to get my VS Code instance that is connected to an AWS IRIS instance to edit/save/compile .csp files, but it's failing to work and I'm not sure why. The ".csp" is associated with the objectscript-csp code, and the server is connected, but things just don't act like they are enabled.

Should this work? and if so, what might I have missed in configuring things?

Recently viewed a demo on the new Dynamic Objects in InterSystems (we are still running 2016.1); together with the upcoming IRIS data platform I started thinking about possibilities of building dynamic databases. That is, I can imagine some projects were it might be really nice to store dynamic objects and then run sql queries on them without ever defining the fields of the dynamic objects (i.e. not at storage, but only if you run your sql query).

In my Data Transformation, the Target class needs to create a new List of objects (ListOfObj), depending on some conditions of Source class (Source/Target are completely distinct/different classes).

I experimented with Lists of 'primitive' data types (ListOfDT), and I could add new %String items (as an example) to a List of %String property, with "append" action in DT.

Does anyone have an example, or guidance, how to create new Lists of Objects in data transformation?

For example, if I have a 'container' class like this, it works:
