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.

Question Norman W. Freeman · Jun 27, 2024

I have a class that inherit from AbstractException

I would like to create a new constructor that has 5 parameters :

Class Foo Extends%Exception.AbstractException
{
    Method %OnNew(arg1 As%String, arg2 As%String, arg3 As%String, arg4 As%String, arg5 As%String) As%Status
    {
        quit##super("some message")
    }
}

I cannot compile it : 

ERROR #5478: Keyword signature error in Foo:%OnNew, keyword 'method argument/s signature' must be '%Library.String,%Library.String,%Library.String,%Library.String,%Exception.AbstractException' or its subclass

namespace = "%SYS" #change the namespace based on situation

username = "_SYSTEM"

password = "xxxxxxxx"

logfile = "exetask.log"

connection = irisnative.createConnection(hostname, port, namespace, username, password)

dbnative = irisnative.createIris(connection)

# dont disturb upto here

There's a distinct difference between the control sequences issued by Windows ssh.exe (OpenSSH_for_Windows_9.5p1, LibreSSL 3.8.2) vs. the RHEL 9 ssh (OpenSSH_8.7p1, OpenSSL 3.0.7 1 Nov 2022) when establishing a session to a Linux host.

Windows ssh issues the following for the Home/End keys:

^[OH - Home
^[OF - End

Linux ssh issues these:

^[[1~ - Home
^[[4~ - End

Welcome to the next chapter of my CI/CD series, where we discuss possible approaches toward software development with InterSystems technologies and GitLab. Today, we continue talking about Interoperability, specifically monitoring your Interoperability deployments. If you haven't yet, set up Alerting for all your Interoperability productions to get alerts about errors and production state in general.

Inactivity Timeout is a setting common to all Interoperability Business Hosts. A business host has an Inactive status after it has not received any messages within the number of seconds specified by the Inactivity Timeout field. The production Monitor Service periodically reviews the status of business services and business operations within the production and marks the item as Inactive if it has not done anything within the Inactivity Timeout period. The default value is 0 (zero). If this setting is 0, the business host will never be marked Inactive, no matter how long it stands idle.

You can use the List query of the %SYS.Audit to output audit logs programmatically.

The sample code is as follows:

Set statement=##class(%SQL.Statement).%New()  
 Set status=statement.%PrepareClassQuery("%SYS.Audit","List")
 Set rs=statement.%Execute()  
 Set tab = $char(9)
 While rs.%Next() {    
   Write rs.%Get("TimeStamp")_tab_rs.%Get("Event")_tab_rs.%Get("Username"),!      
 }

This is an attempt to run a vector search demo completely in IRIS
There are no external tools and all you need is a Terminal / Console and the management portal.
Special thanks to Alvin Ryanputra as his package iris-vector-search that was the base
of inspiration and the source for test data.
My package is based on IRIS 2024.1 release and requires attention to your processor capabilities.

Question Phillip Wu · Jun 18, 2024

Hi,

I want to refresh the data in the databases from the data that exists in the production system.

The IRIS system in both test and production are in a mirror arrangement

Can the refresh be done by doing a backup on the production system and restore the same backup to test?
Could the refresh be customised so that certain databases can be excluded?

Question Lynn Lantz · Jun 25, 2024

I'm trying to keep all writes in local memory.

If you have    S %A="""HI THERE"",!,#,33.33,"" "",$ZTIMESTAMP"

and you         O 2 U 2 W @%A C 2 ZW ^SPOOL                    
^SPOOL(1,1)="HI THERE"_$c(13,10)
^SPOOL(1,2)=$c(13,12)
^SPOOL(1,3)="33.33 67016,59246.6188873"

It works just fine and the output is in the ^SPOOL global. 

However, I'm trying to avoid writing to disk.

I can't find anything besides using the SPOOL device that will allow the use of the "@" indirection.

I tried using streams but it will not allow @indirection.  Neither will set, or execute, or anything.

Integrating frontend React applications with backend services like IRIS database via REST APIs can be a powerful way to build robust web applications. However, one common hurdle developers often encounter is the Cross-Origin Resource Sharing (CORS) issue, which can prevent the frontend from accessing resources on the backend due to security restrictions enforced by web browsers. In this article, we'll explore how to tackle CORS issues when integrating React web apps with IRIS backend services.

Creating the Schema

We start by defining a simple schema named Patients:

Question Oliver Wilms · Jun 23, 2024

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")

    set newObject = {}.%FromJSONFile(file)

    write !,"Property newObject.a is "_$LENGTH(newObject.a)_" characters long."

I have JSON object which contains file references. I need to replace the file reference with base64 encoded file which is up to 10MB.

I tried the following but it did not work as expected:

do dynObj.%Set("data",pStream.ReadLineIntoStream(.tSC))

Question Alin Soare · Jun 20, 2024

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.

Here you can read the official Meta documentation.

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.
The method of execution is as follows.

Question Veerraju Grandhi · Jun 9, 2024

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. I have seen updating information in management portal getting updated in cpf file but vice versa i am not aware. i did not try though.
