#InterSystems IRIS

I had a customer the other day ask how GREFs are measured and how the relationship of the host, storage, and DB engine all influence that number measured in hundreds of thousands or millions.  Is there any good documentation that explains this and/or assists with calculating a GREF count?

I am receiving Mirroring updates to an IRIS for Health async reporting server and need to pause the mirroring journal processing to periodically quiesce the database to rebuild cubes and custom staging tables.

What API or web service can I use to quiesce the reporting server and then later initiate catch up?

Hey Community, 

Learn how you can develop a Node.js application and connect to InterSystems IRIS data platform through the Native API:

⏯ Using Node js to connect to InterSystems IRIS

InterSystems Native SDK for Python is a lightweight interface to InterSystems IRIS APIs that were once available only through ObjectScript.

I'm especially interested in the ability to call ObjectScript methods, class methods, to be precise. It works, and it works great, but by default, calls only support scalar arguments: strings, booleans, integers, and floats.

But if you want to:

• Pass or return structures, such as dicts or lists
• Pass or return streams

You'll need to write some glue code or take this project (installs with pip install edpy). edpy package gives you one simple signature:

call(iris, class_name, method_name, args)

which allows you to call any ObjectScript method and get results back.

Hi developer folks!

Thanks to all of you who start the development with InterSystems IRIS from the basic development template!

Recently, thanks to @Dmitry Maslennikov's contributions I've updated the Dockerfile to make the development simpler, images lighter and the building process faster. And it looks more beautiful too ;)

Here is what changed:

Hi,

I am in a situation where my container is on UTC time (as is the host). But I need to send a datetime to a machine in a specific time zone. Various languages have constructs for doing that, sometimes you need a library

python has the pytz library.

We prefer a solution which is ObjectScript only.

Hi,

I am using IRIS for Windows (x86-64) 2019.1.1

I have.

1. Created a BS with SQL Inbound Adapter which successfully connects and gets rows from DB .

2. Created a request message is populated with results of SQL query.

3  Created a BP with HL7 Router + Routing Rule + Transformation + Send to Target (BO).

4 . Created BO sending HL7 to file.

i am getting the following error.

ERROR <Ens>ErrException: <PROPERTY DOES NOT EXIST>zOnRequest+1^EnsLib.MsgRouter.VDocRoutingEngine.1 *DocType,Test.SQLtoHL7Req -- logged as '-' number - @''

What am i missing

Thanks.

How would you like to be able to access the Web Terminal directly from your VSCode?

Hey Developers, 

See how you can develop a .NET application and connect to InterSystems IRIS® data platform using one or more APIs:

⏯ Using  NET to Connect to InterSystems IRIS

The InterSystems IRIS has excellent support for encryption, decryption and hashing operations. Inside the class %SYSTEM.Encryption (https://docs.intersystems.com/iris20212/csp/documatic/%25CSP.Documatic…) there are class methods for the main algorithms on the market.

IRIS Algorithms and Encrypt/Decrypt types

As you can see, the operations are based on keys and include 3 options:

• Symmetric Keys: the parts running encrypt and decrypt operations share the same secret key.

Hi Everyone,

              I am a very new to IRIS Object Script Development. There is a  usecase where I have to execute a .sh file from the object script. I am looking for examples for that, but what I find is the ways to execute the shell commands. Can you please point me to some examples executing a .sh file. Thanks in Advance

Hi developers. I often miss the ZPM program on a clean system. Nothing complicated? Take and install. And in one line? Especially in a docker container. There is a solution. I'm very happy with it;) Maybe the line can be shortened?

set $namespace="%SYS", name="DefaultSSL" do:'##class(Security.SSLConfigs).Exists(name) ##class(Security.SSLConfigs).Create(name) set url="https://pm.community.intersystems.com/packages/zpm/latest/installer" Do ##class(%Net.URLParser).Parse(url,.comp) set ht = ##class(%Net.HttpRequest).%New(), ht.Server = comp("host"), ht.Port = 443, ht.Https=1, ht.

Developer Preview releases are now available for the 2022.2 version of InterSystems IRIS, IRIS for Health, and HealthShare Health Connect.

 This is the first in a series of releases that are part of the developer preview program. Future preview releases are expected to be updated biweekly and we will add features as they are ready.  This program allows us to get feedback on capabilities and enhancements as they're available.  You'll see below a list of enhancements that are targeted for 2022.2.  Some these are not included in the first developer preview.  Look for those over the coming weeks.

We recently migrated to IRIS. Before, the CACHE.EXE executable could be invoked from a batch file directly : 

C:\InterSystems\Cache\bin\cache.exe -s C:\InterSystems\Cache\mgr -U %SYS

This will display the following in console : 

Node: DESKTOP-8H4B321, Instance: CACHE

USER>

Additionally, the pipe instruction can be used to redirect some commands directly

echo write 50 | C:\InterSystems\Cache\bin\cache.exe -s C:\InterSystems\Cache\mgr -U %SYS

I am looking for the same thing in IRIS.

@Ming Zhou asked a great question in https://community.intersystems.com/post/how-get-all-properties-defined-… and the answer sums up exactly why ObjectScript is my favorite.

When I'm first describing ObjectScript or IRIS to someone I always explain that you can write a class, compile it, get a table, and work with your data from an object or relational perspective - whichever is most natural.

I am trying to pass %request.Data from my rest dispatch class to a production so that I can use it in by business operation.  I have created a message that has a property:

Property urlParameters As %String [multidimensional];

to get the data to the production. I am new to intersystems and multidimensional arrays/globals

dispatch class:

Kill parameters
Merge parameters = %request.Data
Set genericRequest = ##class(Core.API.V1.Msg.GenericRequest).%New()
Set genericRequest.

Hi, I tried the following exercise from the IRIS documentation. I updated the username, password and IP address, but receiving this error;

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. --->

I can use the same credentials and IP address to connect ok via VSCode to my local IRIS...

Any pointers much appreciated.

Has anyone here been successfully populating a %Persistent object from calling %LoadFromMemory() with a temp. global?

I have tried using Sample.Person in the SAMPLES namespace. It worked EXCEPT that I have no way to set the id into that Sample.Person objec.

SAMPLES>Merge array(1) = ^Sample.PersonD(1)
 
SAMPLES>Set obj = ##class(Sample.Person).%LoadFromMemory(1,.array)
 
SAMPLES>zw obj
obj=1@Sample.Person  ; <OREF>
+----------------- general information ---------------
|      oref value: 1
|      class name: Sample.

I think it's a known fact that Populate Utility has very limited functionality. It supports only one language and one country. The list of possible values does not have so many options. 

There is a kind of tool that now can help with it, named Faker. It has implementations in different languages, including Python. Since IRIS has now had the Embedded Python feature, Python faker can be implemented in IRIS.

Hi All,

I am preparing for InterSystems IRIS Core Solutions Developer Specialist Certification. I have completed the desired syllabus. Does anyone have any questions dumps. I have already completed the practice paper on Intersystems website.

This formation, accessible on my GitHub, will cover, in half a hour, how to read and write in csv and txt files, insert and get inside the IRIS database and a distant database using Postgres or how to use a FLASK API, all of that using the Interoperability framework using ONLY Python following the PEP8 convention.

This formation can mostly be done using copy paste and will guide you through everystep before challenging you with a global exercise.
We are available to answer any question or doubt in the comment of that post, on teams or even by mail at lucas.enard@intersystems.com .

Hey Community, 

In this webinar, we’ll discuss how you can now easily integrate Apache Kafka within InterSystems IRIS data platform, including via interoperability productions and programmatically via API calls, as both a producer as well as a consumer of Apache Kafka messages:

Hi Community,

I'm building a browser only code editor for IRIS. Here is a video demonstration. It's still very much "work in progress", more updates to come. I will also add it to ZPM soon.

I'd like to to assign a value to a variable, depending on the results of a condition. The equivalent of what can be done in c++ with the following:

(a>b) ? a=1:a=0;

Or in python:

a = 1 if a>b else 0

This makes the code much more readable and compact.

In objectscript it would be:

if (a>b){
    a=1
} else{
    a=0
}

Hey Developers,

We're pleased to invite you to join the next InterSystems IRIS 2020.1 Tech Talk: DevOps on June 2nd  at 10:00 AM EDT! 

In this InterSystems IRIS 2020.1 Tech Talk, we focus on DevOps. We'll talk about InterSystems System Alerting and Monitoring, which offers unified cluster monitoring in a single pane for all your InterSystems IRIS instances. It is built on Prometheus and Grafana, two of the most respected open source offerings available.

Next, we'll dive into the InterSystems Kubernetes Operator, a special controller for Kubernetes that streamlines InterSystems IRIS deployments and management. It's the easiest way to deploy an InterSystems IRIS cluster on-prem or in the Cloud, and we'll show how you can configure mirroring, ECP, sharding and compute nodes, and automate it all.

Finally, we'll discuss how to speed test InterSystems IRIS using the open source Ingestion Speed Test. This tool is available on InterSystems Open Exchange for your own testing and benchmarking. 

I would like to introduce my new project for the Globals Contest. A very new view for the globals browser
