• This 5-day course teaches programmers how to use the tools and techniques within the InterSystems development environment to build high-performance transactional applications. Learners build a complex application using an IDE, object-oriented design, SQL and unit testing.
• This course is applicable for users of InterSystems IRIS Data Platform and Caché.
• Many benefits are offered by being physically in the classroom with our instructors for a more personalized educational experience.

Hello Everyone,

Last month, we asked for input from the IRIS community regarding exam topics for our InterSystems IRIS SQL Specialist and Expert exams. We will close the window for providing feedback on the exam topics on Thursday, August 31st, 2023. Thus, if you would like to have your say in what topics are covered on the exam, this is your last chance!

To show our appreciation for helping us validate our exam design, we will hold a raffle where 15 survey respondents will be chosen to receive a $50 gift card. The gift card is a Tango Card that can be redeemed at any number of online retailers.

Hi Team,

Is there any way to take a clone object of executed query result of %SQL.Statement 

Set statement= ##Class(%SQL.Statement).%New()
Set pre = statement.%Prepare("Select * From TableName")
Set  result = = SQl.%Execute()
Write result.%ConstructClone(,.cc) ; ConstrcutClone was overridden in the class %SQL.StatementResult

I can loop result.%Next() multiple times if clone was taken from the object

We are updating a C# module which creates consumes an OdbcConnection from System.Data.Odbc.  This module used to create a DSN-less connection through the InterSystems Cache driver, and we are updating it to call the IRIS ODBC35 driver following migration of the target database.

Hi Community,

Whenever I insert a decimal value with trailing zero(ex:12.0000) value in my JSON object dynamically through %Set method. It truncates the trailing zeros. However If I use literal constructors { } It working as expected.  So, In my case the JSON will be generated dynamically. I can't go with "Curly Bracket { } " and the JSON schema not string as well.
Is there any way to fix this?

set json = { "decimal": 12.000}
    zw json
    set json1= ##Class(%DynamicObject).%New()
    do json1.%Set("decimal", 12.000) ; this is consider as stringdo json1.

Hello,
I would like to do the following :

set name = $name(^A)
for i=1:1:10
{
    set$qsubscript(name, i) = "TEST"_i //dream code that does not work
}
set @name = ""//will create ^A("TEST1", "TEST2", "TEST3", ... , "TEST10") = ""

Unfortunately, unlike $PIECE(), $QSUBSCRIPT() is not bidirectional.

Is there a way to do what I described, in a clean way ? (something supported by the system) 

I would like to avoid :

- using a custom made solution (eg: appending keys one by one to a string, adding commas when needed) unless it's failproof (eg: can deal with commas in keys, non string

Hi,

i'm starting to try to switch to VS Code with ISC integration plugins.
Everything seems fine until i get to and environment with CCR enabled. I can't open any class in RW and i don't know how to check the class out.

Is it supported? What do i need to do to use it?

Thanks

Pietro

As noted in the previous article Native API has some limits.
So I did some research on a more Terminal-like interface that
provides me with access like a console or the IRIS terminal
to allow my  $QUERY over a global and other nice commands
that are not supported/mapped in NativeAPI for ObjectScript.

The basic tools are well-prepared and available.

• Connection() creates a fully operational and stable partition for me
• Function() allows calling any routine or method I need
• similar ClassMethodValue and ClassMethodVoid

There is just no method CommandLine and some already prepared code is needed.

I have tried many methods from super classes of %CSP.REST but I can't find a method I can override that will run after the %response object is created so I can set a header that is common to each implementation method.  It's one line of code in each method to set the header but it would like to make it super easy, simple and just have a method that runs on, before, after the implementation method to set this common header (we want to return the API version in each responses HTTP headers.

Any ideas?

InterSystems IRIS Adaptive Analytics version 2023.2 is now available from the InterSystems Software Distribution site.  This new release brings along some great enhancements included with our partner AtScale's Version 2023.

InterSystems Kubernetes Operator (IKO) 3.6 is now Generally Available.  IKO 3.6 adds significant new functionality along with numerous bug fixes.  Highlights include:

• Easily include Web Gateway sidecars for compute and data nodes.

We are about to embark on a development where we'll be taking HL7 messages and generating PDF reports from them. We are wanting to future proof our development efforts within the constraints of our currently deployed platform and future upgrade options. We are currently running on Ensemble 2018, though an upgrade to Iris is anticipated - at some indeterminate point in the future. We are aware of Zen Reports and InterSystems Reports (Logi) as technology options, but are also unclear on some details. A roadmap and guidance from those who've done this kind of thing before would be great!

※Use this method if you want to compare databases that have been replicated using mirroring, shadowing, or some other mechanism.

You can use the DATACHECK utility to compare global variables. Please refer to the document below.

Routine comparisons use the system routine %RCMP or the Management Portal.

Below is how to use it in the Management Portal.

Hey ISC Community!

For a small automation feature I would like to login to the IRIS shell non-interactively, skipping the whole username and password prompts, providing the credentials through other means. Something in the fashion of "iris session <instance-name> --user myuser --pass mypass" would be great, but the session tool itself doesn't seem to be capable of doing this.

Does anyone know a way to accomplish this? It need not be through "iris session", any way that can be automated would be fine. Disabling authentication for the terminal is not an option, though. 

This question originally appeared in the comments of the post: Download globals from a particular server
 

This article was inspired by a recent question from @Evgeny.

Hi Community,

Enjoy watching the new video on InterSystems Developers YouTube:

⏯ InterSystems IRIS Scalability: New & Next Plus Ultra @ Global Summit 2023

In this article, we will analyze the intricacies of setting up tables and graphs to improve the readability of data.

Logi offers a rich set of data visualization tools. You can find anything from a wide variety of chart templates to custom CSS styles. Understanding the assortment of settings and options can be quite difficult. First, we will create a chart and a table with default settings, and give them a presentable look using InterSystems Reports (powered by Logi Report).

Suppose we need to display three directions of data at once on one chart.

Hello,

I have a EnsLib.HL7.Operation.FTPOperation that uses SFTP protocol and public/private key to connect to an external vendor moveitcloud.

Issue: The vendor is planning to enable Multi Factor Authentication for this file transfer account.

Question: Have you configured a SFTP operation to use Multi factor Authentication? If not, is there another way?

Thank you,

Hello,

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

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')"

________________________________________

But if I had "Cardinality = many"
Relationship StudentName As MN.

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'.

I have tried using $$$TRACE within my operation to capture the different elements that are being sent to verify the Server, URL, SSL Configuration, and payload.

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.

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.

But how do we get the %Stream.GlobalCharacter in the Python ClassMethod?

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 ?

I took a look at Portal (eg: in dashboard, "System Resource Statistics") but couldn't find anything. Web Gateway panel provide information about connections but this is incoming connections for CSP pages.
