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.

Hi all,

I am trying to use some process private variables (percent variables) in Triggers.

I am referring to values from $System.Process, like the ClientIPAddress and CSPSessionID.
These do to not contain values and I suspect it is bacause of scope. I also checked, and the %session variable is not available if the change originated from a CSP request.
I know that in triggers the scope of the variables are to be kept local, that is why NEW is to be used.

Some weeks ago, I was reading a book by Stephen Hawking and Leonard Mlodinow, The Grand Design. At a certain point, trying to define why do we exist? , why do we use the models we use in physics?, ...those kind of things you know... they pointed at the Game of Life example invented by the mathematician John Coward in 1970... Basically he wanted to show that a system with really basic fundamental laws (Physics) could evolve and "live" to become a more complex system (Chemistry) in which "something" (humans) could work out its own model and complex rules to explain its reality… the rules for this deterministic model that he exposed were so basic that I thought it could be funny to implement them in ObjectScript when I had some spare time... there are others implementations in JavaScript and other languages... but not in ObjectScript... and that had to be corrected!!… so here you are!

Hi Community!

I think everyone keeps the source code of the project in the repository nowadays: Github, GitLab, bitbucket, etc. Same for InterSystems IRIS projects check any on Open Exchange.

What do we do every time when start or continue working with a certain repository with InterSystems Data Platform?

We need a local InterSystems IRIS machine, have the environment for the project set up and the source code imported.

So every developer performs the following:

  1. Check out the code from repo
  2. Install/Run local IRIS installation
  3. Create a new namespace/database for a project
  4. Import the code into this new namespace
  5. Setup all the rest environment
  6. Start/continue coding the project

If you dockerize your repository this steps line could be shortened to this 3 steps:

  1. Check out the code from repo
  2. Run docker-compose build
  3. Start/continue coding the project

Profit - no any hands-on for 3-4-5 steps which could take minutes and bring head ache sometime.

You can dockerize (almost) any your InterSystems repo with a few following steps. Let’s go!

This is the third post of a series explaining how to create an end-to-end Machine Learning system.

Training a Machine Learning Model

When you work with machine learning is common to hear this work: training. Do you what training mean in a ML Pipeline?
Training could mean all the development process of a machine learning model OR the specific point in all development process
that uses training data and results in a machine learning model.

Making the most of $Query

I ran into an interesting ObjectScript use case today with a general solution that I wanted to share.

Use case:

I have a JSON array (specifically, in my case, an array of issues from Jira) that I want to aggregate over a few fields - say, category, priority, and issue type. I then want to flatten the aggregates into a simple list with the total for each of the groups. Of course, for the aggregation, it makes sense to use a local array in the form:

agg(category, priority, type) = total

Such that for each record in the input array I can just:

How to understand what's wrong with compilation if the compilator just hides errors?

Compilation started on 05/15/2023 15:58:11 with qualifiers 'cuk'

Detected 1 errors during compilation in 0.003s.


Compilation started on 05/15/2023 15:58:32 with qualifiers 'cuk'

Detected 1 errors during compilation in 0.002s.


Compilation started on 05/15/2023 15:58:51 with qualifiers 'cuk'

Detected 40 errors during compilation in 0.089s.

40 errors, and what do I have to do with this so valuable information?

Monitoring Platforms

With System Alerting and Monitoring (SAM) being deprecated in the near future..

  • What is everyone's go-to for Monitoring IRIS?
  • What is readily available?
  • What is the cost surrounding it?

Just trying to get ideas floating around of what we might need to start looking at to satisfy IT leadership.

Thanks

Scott

Still working on my first External REST API call, and I am struggling to find the exact answer I am looking for... I get a JSON response from my API call but I am not quite sure how to dynamically get the JSON response into the Ens.Response Object with its lists of Arrays that I have defined.

set tSC = ..Adapter.SendFormDataArray(.tHTTPResposne,"POST",tHTTPRequest,,,tURL)

Hi Community,

Can anyone point me to the docs that show how to add automatic class documentation for the arguments used in a method call? I can auto document the class, methods, properties etc. with the "///" but can't figure out how to get the nice argument documentation for the arguments used when calling a method.

Thanks in advance

Globals, these magic swords for storing data, have been around for a while, but not many people can use them efficiently or know about this super-weapon altogether.

If you use globals for tasks where they truly shine, the results may be amazing, either in terms of increased performance or dramatic simplification of the overall solution (1, 2).

Globals offer a special way of storing and processing data, which is completely different from SQL tables. They were first introduced in 1966 in the M(UMPS) programming language, which was initially used in medical databases. It is still used in the same way, but has also been adopted by some other industries where reliability and high performance are top priorities: finance, trading, etc.

Later M(UMPS) evolved into Caché ObjectScript (COS). COS was developed by InterSystems as a superset of M. The original language is still accepted by developers' community and alive in a few implementations. There are several signs of activity around the web: MUMPS Google group, Mumps User's group), effective ISO Standard, etc.

Modern global based DBMS supports transactions, journaling, replication, partitioning. It means that they can be used for building modern, reliable and fast distributed systems.

Globals do not restrict you to the boundaries of the relational model. They give you the freedom of creating data structures optimized for particular tasks. For many applications reasonable use of globals can be a real silver bullet offering speeds that developers of conventional relational applications can only dream of.

Globals as a method of storing data can be used in many modern programming languages, both high- and low-level. Therefore, this article will focus specifically on globals and not the language they once came from.

Under the previous python binding method (Cache) it was possible to pass in parameters, execute a class query, and fetch the result sets. I have been unable to find a way to do this via PYODBC or the Native API (perhaps I am just missing something).

My work around is to create a SQLquery string and execute it through a cursor. I would much prefer to simply execute the debugged and more secure class queries that already exist and and have been precompiled.

Any pointers would be greatly appreciated

Thanks,

Sinon

Hi Developers!

Thank you for using ZPM Package Manager and contributing more and more useful packages to the public registry!

But as you already aware ZPM packages are always deployed with source code.

Do you think we need to add the option to deploy without source code - e.g. if you want to deploy a commercial package?

Will you develop commercial modules if there will be an option and deploy it with ZPM?

How do you deploy commercial applications today?

Hi,

I've created an Object Gateway via the System Management Portal, and installed the following Java classes to allow connectivity between the IRIS server and RabbitMQ ...

RabbitMQ.jar

amqp-client-5.18.0.jar

slf4j-api-1.7.36.jar

slf4j-simple-1.7.36.jar

I've used the Java Gateway wizard via Studio and compiled the java classes that this would refer to, and a quick test worked on Day 1. However, on Day 2, on trying to connect, I got this error :

<ZJGTW>%ProcessErrorNew+11^%Net.Remote.Proxy.1

Hello everyone, I need some help.

I have to send some events for a government WebService that I already imported the WSDL and XSD's and It worked fine and I'm able to build the message and connect into the service, but It has been rejected with the message that the XML is wrong and the only diference between the Caché SOAP message to all the examples that the government gave us is the header:

This is how the Government is expecting the message:

I want to have a script that can run from the usual unix, linux, or aix command line. It has to be able to get into an irissession and use set statements to get data using sql. It seems like I'm in a catch-22. When I use the irissession SERVER command at the command line, I can't run a script. When I put the irissession SERVER command in a script, it won't run anything in the script after that.

My goal for this script is to get this information and put it into a file which I can then parse.

ZPM is now InterSystems Package Manager (IPM)

I'm pleased to announce a milestone in the lifecycle of the ObjectScript package manager, ZPM. The package manager has offered developers the ability to neatly package up ObjectScript code and deployment configuration settings and version information in a convenient way. Over the last few years, it has evolved greatly into an integral part of many development workflows.

I am doing a HL7 data transformation with object script but need to only write a substring from the first "(" of the NTE-3 field to the end.

example

Input: NTE|1|||Some text (HI) (321)|ABC

Desired Output: NTE|1|||(HI) (321)|ABC

Basically I'd like to delete "Some text ".

If I were writing a shell script I would use sed 's/^.*(/(/' with perhaps a modification to get only the first.

I use the function wizard but can't seem to get the right code.

Docker 20.10.14 (released March 23, 2022) changes the Linux capabilities given to containers in a manner that is incompatible with the Linux capability checker in InterSystems IRIS 2021.1 (and up) containers.

Users running Docker 20.10.14 on Linux will find that IRIS 2021.1+ containers will fail to start and the logs will incorrectly report that required Linux capabilities are missing. For example:
