#InterSystems IRIS

Hello,

What is the difference between the installation-kit for IRIS and IRIS_ML and is there a different licensing ?

Regards,

Kurt Hofman.

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')"

I am working on my first REST operation to send a API Request to an internal server within our Network. I have finally got past the point of being able to connect using a SSL/TLS Configuration, but I am getting a ERROR <Ens>ErrHTTPStatus: Received non-OK status 403 from remote HTTP server: 'HTTP/1.1 403 Forbidden'.

Introducing Django

Django is a web framework designed to develop servers and APIs, and deal with databases in a fast, scalable, and secure way. To assure that, Django provides tools not only to create the skeleton of the code but also to update it without worries. It allows developers to see changes almost live, correct mistakes with the debug tool, and treat security with ease.

To understand how Django works, let’s take a look at the image:

Hi,

I am new to Objectscript so need some help please.

How would I check a string for special characters as per below?

/^[!@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]*$/

Thanks so much,

Hi All,

If I remember it correctly there is a functionality in IRIS to make this possible.

I've got two incoming Business Services of files from different sources.

BS1: An Ens.StreamContainer with some info and metadata which point to a specific file. Ens.StreamContainer will be send to a BP.

BS2: The files where the metadata points to. It's in the Ens.StreamContainer

But dependent on the flow the file could be later available on BS2. So I want the BPL to wait for the file to arrive at BS2. 

Then in the BPL I want to do some merging stuff with the 2 Ens.StreamContainers

Hi All,

We're doing our first babysteps with embedded Python and IRIS with an interoperability solution. We want to convert a CSV file to an Excel xlt file.

As service we've got a EnsLib.File.PassthroughService which picks up a csv file

As operation we've got a EnsLib.File.PassthroughOperation which writes the Excel file.

In the middle:

We've created an Business Process with an %Stream.GlobalCharacter in the Request and a %Stream.GlobalCharacter  in the Response.

Hi!

Currently, I'm working on a script using %SYS.Journal API.

My journal files are compressed, following the documentation the compression is zstd.

I tried to unzip a file with zstd tool, ex: 

apt-get update
apt-get install zstd

zstd -d 20230806.001z -o 20230806.001

20230806.001z        : 92.03%   (909312 => 836859 bytes, 20230806.001) 

Unfortunately, the unzipped file is invalid:

Write##class(%SYS.Journal.File).IsValidJournal("/usr/irissys/mgr/journal/20230806.001")

Hi.

Is there any function to validate JSON string returning status?

Can I get help with connecting a node-based client with the IRIS DB? Need the same for firing queries with node-based Cypress framework ?

There is several classes that allow to create TCP/IP connections (eg: to connect to a service).

Example : %Net.FtpSession (port 21), %Net.HttpRequest (usually port 80 or 443)

AFAIK connection will stay open unless closed explicitly or if variable that hold the instance is garbage collected.

Is there a way to get a list of all active (open) TCP/IP connections IRIS is maintaining so far ?

Hi,

I try to initialize some properties of a %DynamicObject during his creation.

I Try to use InitialExpression this way :

Property refDate As %Date [InitialExpression = $piece($horolog,",",1)];

But it doesn't compile

I don't found if %DynamicObject can have a constructor to initialize properties by a calculated value, like other languages.

Hi,

Using Interoperability, I can't figure out how to create separate XML's files from a CSV-file using the GUI-features Record Maps/Complex Record Mapper -> Data Transformations. I'm familiar with reading/writing the files using File Service/Operation, but don't understand the processing-steps. The preferred method by my colleagues is to do this without any Objectscript or Embedded Python coding, but if this can only be done by some coding that's fine as well.

See example below. Any help is appreciated!

Kind regards, Ties Voskamp

I asked the question in email and get answers from those colleagus.

Question:

The 2023.2 releases of InterSystems IRIS Data Platform, InterSystems IRIS for Health, and InterSystems IRIS Studio are now Generally Available (GA).

RELEASE HIGHLIGHTS

2023.2 is a Continuous Delivery (CD) release. Many updates and enhancements have been added in 2023.2:

Private Web Server

Starting with this release:

InterSystems announces its seventh preview, as part of the developer preview program for the 2023.2 release.  This release will include InterSystems IRIS and InterSystems IRIS for Health.

Discontinuation of the Private Web Server (PWS)

A major topic in this release is the discontinuation of the Private Web Server (PWS) from the installers.  This feature has been announced since last year and it's removed from InterSystems installers, starting with this developer preview.

See this note in the documentation. Additional information related to this topic can be found here.

Our previous code golf ended with an overwhelming win, so now it's time for another one. Parenthesis Hell is a Lisp-like esoteric programming language(esolang). As a Lisp-like language, the code consists only of nested matched pairs of opened and closed parenthesis. Your task is to write a method that receives a string of parenthesis and returns 1 if the order of the parenthesis is valid. For example, the string of parenthesis (())() is valid because it contains a matched pair of opened and closed parenthesis at each position. The string ()((()))) is not valid because it contains one unmatched parenthesis.

Hi,

Any recommendations on how i can add a logic if an incoming record that is already existing in the table but different total amount value. I need to subtract the totalamt value on the input file vs the totalamt value on the table and update the table with the difference of totalamt. Any help is much appreciated. Thanks!

First time setting up a SSL/TLS connection, and I am running into issues when I call it from within a Business Operation. I used openssl to generate a RSA 4096  SHA512 key/csr request for our Active Directory Certificate Service to generate a Certificate Chain for me to use within RedHat. I was 
able to connect to our Web Service server using a generic request from terminal, however when I try it from our Business Operation I am running into issues.

I tested the SSL/TLS connection using the following commands from the terminal...

DEVCLIN>set request=##class(%Net.HttpRequest).%New()

Recently I started moving some of our JDBC Gateway configurations over to using the Microsoft JDBC Gateway driver instead of using the jTDS open source driver. I have noticed since then that those Objects that are using Microsoft JDBC Driver are throwing a lot more errors than the jTDS driver ever did, which I can understand however I am puzzled that I keep running into an issue with the Java Gateway Service within the Interoperability engine.

InterSystems FAQ rubric

You can set individual error pages for the following Web Gateway error messages/system responses:

• server error
• server busy
• server unavailable
• server timeout
• connection closed

Settings are made on the Web Gateway Management screen ([Management Portal] > [System Administration] > [Configuration] > [Web Gateway Management] > [Configuration] > [Default Parameters]).

In the Error Page section of the Default Parameters menu, set the filename of the html page to display or the URL to redirect to when an error occurs.

Have Docker running in Ubuntu and successfully downloaded IRIS Healthcare ML Community to local machine.

Cannot figure out how to launch IRIS...help!

Thanks, all...

Hi Developers, I'm currently doing a demo about building a front end UI doing data analytics and setup a performance test with large data objects, therefore using "Populate Utility" could help me auto generate some sample data that I can play with.

Within this post I would like to share my experience of using Populate Utility, including using POPSPEC Parameter.

Hello,

I need AES ECB with PKSC7 padding for an interface.
Unfortunately, the %SYSTEM.Encryption.AESEncode cannot do this.

Therefore I wanted to include the following python lib.
PyCrptydome -> https://pycryptodome.readthedocs.io/en/latest/index.html

We need to install the package offline on the system. So I downloaded it and put it in the MGR/Python/ directory.

However, when I try to install it, I get the following error message:

Hi Community,

Enjoy watching the new video on InterSystems Developers YouTube:

⏯ Introduction to InterSystems Products

InterSystems has corrected two defects.

The first defect can cause an ECP application server to hang. This defect is only relevant to ARM and IBM Power processors; it is present in version 2022.1.2 and 2022.1.3 of InterSystems IRIS®, InterSystems IRIS for Health™, and HealthShare® Health Connect. The correction is identified as DP-423661. The defect is addressed in all future versions. 

InterSystems FAQ rubric

You can search for a specific global variable in the journal file using the ByTimeReverseOrder query of the %SYS.Journal.File class and the List query of the %SYS.Journal.Record class.

The role of each query is as follows.

A) %SYS.Journal.File query of the ByTimeReverseOrder class

You can get the journal file name. Results are returned in descending order of journal file name. 

InterSystems IRIS currently limits classes to 999 properties.

But what to do if you need to store more data per object?

This article would answer this question (with the additional cameo of Community Python Gateway and how you can transfer wide datasets into Python).

The answer is very simple actually - InterSystems IRIS currently limits classes to 999 properties, but not to 999 primitives. The property in InterSystems IRIS can be an object with 999 properties and so on - the limit can be easily disregarded.

Hi all,

I am using %Library.ResultSet to execute my query which I have something like this.
Query GetABC() As %SqlQuery [SqlProc]{

}

After I execute this query and a resultset it returns from this. Now What I want to know is the SQL statement which will have the values dynamically added into while execution.

I like to add documentation to the top of every class I write. Is there a way to modify or create a template that would automatically add the lines below to the top of the class? I primarily use Studio IDE but would like to be able to do this using VS Code as well.
