#InterSystems IRIS

Hi Community!

Suppose I have a property in a ObjectScript class:

Property values As list Of %String

What an SQL query can help to return the values of the property as JSON array via SQL access (JDBC)?

Suppose we need to store millions of values temporarily, that means, we don't care about them if we lose them but our application use them to get realtime information. Should I use Cachetemp or whatever other DB without journaling enabled? If answer is Cachetemp, shouldn't be a problem if we decide to scale using App Server + ECP? I'm not sure what would happen with the app logic in such architecture as I guess I couldn't map and share cachetemp...

Any idea/suggestion?

Hi Community!

What's the limit for Namespaces and Databases for one InterSystems IRIS installation?

Yes, I checked with documentation but cannot find it at once.

The Caché / Ensemble standard distribution contains in namespace SAMPLES
a nice example of a CSP page consuming WebService as a Client.
I have modified it not only to display the replies but to feed them back into a Global.
I used the classic Hyperevent to achieve this. The replies end up as a log in global^WSREPLY.
When there is no input anymore the page closes and goes away.

There are 2 versions with visible and hidden display during operation.
dc.WSCSP.reverseVerbose.cls and dc.WSCSP.reverseHidden.cls

The message to send is simply passed as a hash after the CSP_URL. (Mind URL encoding!)

When I run the following cmd in Ubuntu 18.04

the container is created and stays running

But when I run this cmd, the container is created but exits immediately

Not sure why it is doing this.  if anyone can shed some light, it would be most appreciated.

Good News!! You can use now the Free InterSystems IRIS Community Edition in the AWS Cloud

Hello,

It's very common that people new in InterSystems IRIS want to start to work in a personal project in a full free environment. If you are one of this, Good News!! You can use now the Free InterSystems IRIS Community Edition in the AWS Cloud.

It is pretty easy to create a new EC2 instance from InterSystems IRIS Community Edition in AWS Marketplace.

After that you have to launch your instance and then you'll can access it using ssh like this:

(note: be sure you have 'chmod 400' at pem file)

Hi All,
I created a Business Operation to Integrate with Amazon S3.
I have used HTTP Outbound Adapter for the same. Used Get method of Adapter Class.
Basically in a request I want to send Unique File Name and File and in Response I want to get Version ID and if operation was successful, then set flag to true.
I have created a class for request in that I have two properties, as shown Below :
   

    Property fileName As %String;
    Property file As %GlobalBinaryStream;
This is in my Operation Class
 

Hello Everybody and Happy 2019!

I hope this finds you well, relaxed and ready to tackle the challenges we'll face in 2019.

When a new period of our life begins it is nice and at times useful to consider what the previous period has been like and as the sage of old used to say "historia magistra vitae" or history is a teacher for our lives, maybe we can try to get some insights for the future. So, what did we see and experience in 2018?

1 - Information, knowledge & the machine!

Hi Community!

We're pleased to invite you to the InterSystems Benelux Symposium 2019!

Date: February 5 - 6, 2019

Place:Radisson Blu Astrid Hotel, Antwerp, Belgium 

Please find all the details here: https://bnl.intersystems.com/symposium-2019

Today in docs I found this example using NULL:

 WRITE $LISTVALID($LB(NULL)),!

simplified

zzdump $LB(NULL)

and NULL can be case-insensitive:

zzdump $LB(null)

seems the same as just:

zzdump $LB()

But if null variable is defined then list would contain value from variable. Case sensitive in that situation.

Does anyone have any Idea what is this? Is NULL used anywhere besides as a list element?

Recently I needed a classmethod that returns annotation value based on a name of a activity.

As doing it at runtime seemed inefficient, I wrote compile-time utility that iterates over all business process activities and generates relevant code.

This code could be used in a variety of situations when you need to iterate over business process activities, just add it as a secondary superclass to your BPL processes.

Let's say I have a property as a variable value:

set propName="Country"

Is there a method to determine, should I quote it to access the object, so would the correct code be:

write obj."Country"

or just simple

write obj.Country

is enough?

Running predictive models natively in an InterSystems IRIS Business Process has of course always been the goal of our PMML support, but somehow never made it into the kit because there were a few dependencies and choices that needed addressing and answering. Anyhow, thanks to some pushing and code kindly provided by @Amir Samary (Thanks again Amir!), we finally got it wrapped in a GitHub repo for your enjoyment, review and suggestions.

The preview release of InterSystems IRIS 2019.1 is now available - give it a try!

Kits and container images are available via WRC's preview download site.

InterSystems IRIS Data Platform 2019.1 is the third major version of InterSystems IRIS.  It has many new capabilities including:

• Significant enhancements to SQL usability and performance
• Improved scalability and operations for sharded clusters
• Client language updates and performance boosts
• New interoperability capabilities that speed configuring and troubleshooting of productions
• System security, performance, and efficiency enhancements

Hi,

I'm using node.js to access to Iris.

Considering this globals:

^Customer(1, "Address", 1)="London"

^Customer(1, "Address", 2)="UK"

^Customer(1, "Name")="Jane K. White"

^Customer(2, "Address", 1)="Reigate"

^Customer(2, "Address", 2)="UK"

^Customer(2, "Name")="Peter R. Black"

^Customer(3, "Address", 1)="London"

^Customer(3, "Address", 2)="UK"

^Customer(3, "Name")="Paul J. Green"

I retrieve all customers with: 

mydata.retrieve( { global: "Customer" },

"array",

function(error, result) {

if (error) {

// error (see result.ErrorMessage and result.ErrorCode)

} else {

// success

} } );

At the George James Software booth at Global Summit last year we took the wraps off the work we've been doing to make our popular editing and debugging tool Serenji available on the Visual Studio Code platform.

Rather than requiring you to pull code from your namespaces into local files, then push the changes back to the namespace to run it, you work directly in the namespace. In other words, the editing experience is like Studio rather than like Atelier.

As well as editing code you can also debug it directly from VSCode.

After attending the Intersystems DACH conference in Germany at the end of last November and taking part in a few workshops about containers and microservices I took the plunge and installed Docker on home Windows PC, downloaded IRIS 2018.2 preview and got that up and running. Good stuff and I gave myself a pad on the shoulder at that point.

Hi guys,

I have a customer trying to extract data from Hive. I've tried to use Data migration to migrate a table into IRIS with JDBC driver. But the migration task always fails as below

Then I tried to create a link table, the task fails too with the following error:

I've tried several ID combinations such as rowkey+userid, userid + datatime, the results are all errors caused by stream property. 

The source table are composed of only Hive string fields.I wonder how may I migrate Hive tables into IRIS. Thanks.

Hi Team,

              I am interesting to learn InterSystems IRIS data platform. How to I download and install the InterSystems IRIS instance and sandbox. So Please give the instruction for how to I use it.

Thanks & Regards,

There's a new and exciting enhancement to QEWD that has just been released - it's an additional layer of abstraction known as QEWD-Up.  QEWD-Up hides away all the mechanics of QEWD itself, allowing you to focus on just your REST APIs and the code that implements them.

Additionally, and importantly, QEWD-Up simplifies the maintenance of your REST APIs, allowing you (and others) to quickly and easily understand their life-cycle and implementation.

QEWD-Up supports both monolithic application designs and MicroService-based architectures where APIs are broken down by, for example, functional role.

Hi Community!

We are pleased to invite you to the upcoming webinar "Using Blockchain with InterSystems IRIS" on 20th of December at 10:00 (Moscow time)!

Hi,

I want to test the node.js interface to iris with trial sandbox. The node.js documentation refers to get de node package from the instance bin directory. As I'm trying to use the trial sandbox I don't have access to the directory. Please let me know where I could download iris.node package.

Thanks,

Fabian

Hi Community!

We try a new approach to the InterSystems Developers YouTube Videos called "Coding Talks"!

Coding Talks is a short video in which the developer demonstrates a particular feature or functionality of InterSystems Data Platforms which he/she uses to in coding. Typical format: the face on side and editor with ObjectScript.

Check this video I made by myself participating in Advent of Code 2018 and coding with InterSystems ObjectScript in VSCode.

Coding Advent of Code 2018 Using InterSystems ObjectScript 

As a result of Evgeny's recent questions regarding the use of QEWD.js with IRIS in another post, I thought it would be a good idea to create a separate post focusing specifically on how to use QEWD.js to create REST APIs for IRIS.

QEWD.js is,  of course, a Node.js framework, and all the REST API code can be written entirely in JavaScript. 

Hello experts, 

I am new to IRIS and I was told I could get a great hands-on experince with the commuity edition that is currently availabe on mutliple cloud providers.

Unfortunately connecting Atelier to the given IRIS instance has been unsuccessful: 

Accorording to this troubleshooting guide: 

- A single-user license is not sufficient to run Atelier.

According to my License Key: 

   License Type=Single Concurrent User

And my license use is at 100%: 

How am I supposed to connect and test IRIS if the Communty Edition does not provide a suffiscient license? 

Am I missinng somehitng else?

Thanks,

Evgeni

I have a persistent class that represents cities across the United States.  It is below, but basically has a City Id, Name, Lat, Lon and a few other unimportant fields for this issue.  Anytime I attempt to query on the Latitude or Longitude it immediately returns no results.  My first thought was that it was a casting issue so I tried casting both sides to floats, ints, even strings and in all cases it immediately comes back with no results.  I then decided to cast it to a string and attempt a like statement thinking it might be something about how floats are handled, but still no joy.  Any

Hi guys,

Mostly the title.  Let's say my commands are stored in a text file "inFile".  Here was my best guess:

<dir to iris> console IRIS2018 <inFile

For reference, here's an example of the analogous structure that works on Cache:

C:\InterSystems\Cache2018\bin\cache -s C:\InterSystems\Cache2018\mgr -U <namespace to start as> <inFile

Did you know that Caché (and now InterSystems IRIS) has available parser for ObjectScript ?

Well, technically, lexer. It hides under the name of %SyntaxColor class. This class provides API to the DLL used by Studio to do syntax highlighting. As a result if works only under Windows.

It was mentioned in an earlier version of the IRIS documentation that IRIS and Cache should not be installed on the same physical server (port clashes?).

I can't see this warning in the current version of the documentation.

Could someone clarify if this has been resolved in the latest release of IRIS?

I bet that not everyone familiar with InterSystems Caché knows about Studio extensions for working with the source code. You can actually use the Studio to create your own type of source code, compile it into interpretable (INT) and object code, and sometimes even add code completion support. That is, theoretically, you can make the Studio support any programming language that will be executed by the DBMS just as well as Caché ObjectScript. In this article, I will give you a simple example of writing programs in Caché Studio using a language that resembles JavaScript. If you are interested, please read along.
