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.

I am working on JSON and want to be prepared to handle large Objects. I try this code:

ClassMethod MaxLen() As %Status

{

set longStr=""

for i=1:1:$SYSTEM.SYS.MaxLocalLength() { set longStr = longStr_"x" }

write "Maximum string length = "_$LENGTH(longStr)

;

set longObject = {"a":(longStr),"b":(longStr)}

set file=##class(%File).%New("/tmp/longObjectFile.txt")

do file.Open("WSN")

do longObject.%ToJSON(file)

do file.Close()

;

do file.Open("RS")

Hi,

I would like to ask whether there is some option to stop auto-formatting when I compile. The code is sometimes well formatted but the auto-formatter does not work correctly in some situations. I am talking about the compilation in the Studio editor in this image, not about Visual Studio Code.

Thank you in advance,

Alin C Soare.

In this article we are going to see how we can use the WhatsApp instant messaging service from InterSystems IRIS to send messages to different recipients. To do this we must create and configure an account in Meta and configure a Business Operation to send the messages we want.

Let's look at each of these steps in more detail.

Setting up an account on Meta

This is possibly the most complicated point of the entire configuration, since we will have to configure a series of accounts until we can have the messaging functionality.

How to check the size of your data

InterSystems FAQ rubric

Data for InterSystems products (table row data, object instance data) is stored in global variables.
The data size of each global can be obtained by clicking the properties of the global you want to view from the Management Portal > System > Configuration > Local Database > Globals page, and then clicking the Calculate Size button on the Global Attributes page that appears.
To display the data sizes of globals in a namespace, you can call ^%GSIZE utility on the terminal.

I am actually new to IRIS, and we are DevOps/PowerShell/Ansible team. We want to achieve certain administration tasks like updating Memory, Heap size, Lock size etc., in Management Portal through PowerShell. Is there any way i can achieve this without out logging in into Management portal. Off course, we have namespace, user id and password details. We have installed ODBC drive and able to update tables in the IRIS database.

Hi,

Hi have problems to import globals, this is a testing only.

From Caché (v.2012, very older, 8 bits character, Latin1 encode) I created a file exporting globals, file *.gof with de web system utilities,.

When I import these globals to Iris (v2024.1 16 bits character), the restore utility show this error:

InterSystems FAQ rubric

If you want to run an OS executable file, command, or a program created within an InterSystems product when the InterSystems product starts, write the processing in the SYSTEM^%ZSTART routine. (The %ZSTART routine is created in the %SYS namespace).

Before you write any code in SYSTEM^%ZSTART, make sure that it works properly under all conditions.

Hello,

With my team, we're evaluating the different streams existing in order to find good pratices for our project using InterSystems IRIS. In doing so, we found that there exists different forms of the same stream with the %Stream.FileBinary and %Stream.FileBinaryGzip classes. We think that the %Stream.FileBinaryGzip takes less space to be stored, but is there other diferences between these two classes and what would you recomend to use ? Is it the same thing for %Stream.FileCharacter and %Stream.FileCharacterGzip ?

Thanks for your help,

$ZTRAP vs Try/Throw/Catch

I'm scraping my way through some code that's been around for a while, and came across the use of $ZTRAP and (dear GOD) GOTO for trapping and handling errors.

In an effort to "modernize" it and make it, I don't know, less M-ish (sorry old-timers!), I'm replacing it with Try/Catch blocks.

Some questions:

  1. Is this a dumb idea?
  2. Anything I should look out for?
  3. Did I hurt anyone's feelings?

And if the answer to number 3 is Yes, my deepest apologies ... I love you guys! 🤩

Hi Developers!

This is the second post on the resources for Developers. This part is about Open Exchange

Using Open Exchange to Learn InterSystems

InterSystems Open Exchange is a applications gallery of tools, connectors, and libraries which InterSystems Developers submit to share the experience, approaches and do business. All the applications are either built with InterSystems data platforms or are intended to use for development with InterSystems data platforms.

If you are a beginner developer you can take a look at applications in Technology Example category. All the applications in this category come with open source code repositories, so you are able to run the samples and examples in a docker container with IRIS on your laptop or in the cloud IRIS sandbox. Examples:

I would dearly love to avoid manually creating a SEF or XSD file to get the X12 832 (4010) schema into IRIS, but I have been hard pressed to find either downloadable resources or commercial options. The typical recommendation, edi-dev, seems to just do tooling that will help create SEF files, but no longer sells actual SEF files.

Anybody got any good resources that might have these schema files?

Thanks for any help!

Cordially,

Jonathan

Let's say I have an InterSystems IRIS instance with 6 Namespaces:

  • Foo1
  • Foo2
  • Foo3
  • Foo4
  • Foo5
  • Bar

And the number of Foo# namespaces can increase at any time for a number of reasons. I need to ensure that they all have identical configuration globals stored in a DB called CONFIG, so I do the following in my configuration file:

[Map.%ALL]
Global_SYS=%DEFAULTDB
Global_SYS("CommonConfig")=CONFIG
Global_SYS("CommonOtherSettings")=CONFIG
Global_SourceControl=CONFIG

Hello everyone,

Recently, I've been working on a Business Process that processes a large JSON FHIR message containing up to 50k requests in an array within the JSON.

Currently, the code imports the JSON as a dynamic object from the original message stream, obtains an iterator from it, and processes each request one at a time in a loop.

Recently I wanted to get a list of all cached queries and their texts. Here's how to do that.

First create an SQL Procedure returning Cache Query text from a Cached Query routine name:

Class test.CQ
{

/// SELECT test.CQ_GetText()
ClassMethod GetText(routine As %String) As %String [ CodeMode = expression, SqlProc ]
{
##class(%SQLCatalog).GetCachedQueryInfo(routine)
}

}

And after that you can execute this query:

Hello Community,

I have encountered the following SQL problem trying to create a table from a SELECT statement.

I narrowed the problem down to the following example:

1. The SELECT statement alone works as expected. 

SELECT m.Name, h.Status 
FROM EnsLib_HL7.Message m, Ens.MessageHeader h 
WHERE h.MessageBodyClassName='EnsLib.HL7.Message' AND h.MessageBodyID = m.ID

2. But if "CREATE TABLE ... AS" is added it fails

We have an operation that sends a Rest request to an external endpoint. The request includes the secret, which shows up in the Message Viewer. While access to the Production is restricted to only those who need it, we have been asked to remove it from the Message Traces. Is there a way to hide certain information on the Message Viewer ?

Thanks for reading

Hi,

I will try to explain my problem. I have a Main ZenPage on one server that has 2 buttons: each button will launch a different ZenPage on a separate server in an iFrame. All 3 servers have the same user.

Currently, the user logs in to the Main ZenPage, but when they click either button to launch the other ZenPage on the separate server they get the login screen again to login to that server.

Is there anyway I can pass the credentials from the Main ZenPage to the child ZenPages, so that the user doesn't have to login again? Thanks.
