I am looking to run IRIS for UNIX on the Linux Ubuntu 22.04 platform and need to determine which filesystem configurations are considered supported. The three options under consideration are Ext4, LVM with Ext4, and OpenZFS. Currently, the system is running on a raw Ext4 filesystem, but there is a desire to switch to either LVM with Ext4 or OpenZFS to make it easier to handle disk usage.

This leads to two questions:

Are either of these two configurations considered to be tested and supported by InterSystems?

Wondering what version the Information.Schema schema was introduced, so that I can decide how to query the metadata for user defined tables. 

Thank you!

For your convenience InterSystems is posting the typical install steps for the operating systems that are supported with InterSystems IRIS.

For Microsoft Windows, please consult the InterSystems product documentation.

The IRIS installer will detect if a web server is installed on the same machine, which gives you the option to automatically have the web server configured.

All Apache installations will require sudo (recommended) or root permission to install the web server. This requirement supports recommended best practices.

I've created a Rest Service as described here 

Configured the webapplication as described in the previous link, and now have a URL which I call in PostMan

http://VIR-HC-DEV-01.gmmh.nhs.uk:52773/api/mgmnt/v2/parisconnect/PCRest

Which returns the JSON spec as I would expect:

{
    "swagger": "2.0",
    "info": {
        "version": "1.0.0",
        "title": "Swagger Petstore",
        "description": "A sample API to demonstrate features in the swagger-2.0 specification",
        "termsOfService": "http://swagger.

Update - I answered my own question, so I'll just leave this here in case it can help someone.

Hi All

I'm following the tutorial Creating and Editing REST Services and have reached the step Using ^%REST to Create a Service and have encountered an error.

Here is grab of the terminal command:

PARISCONNECT>do ^%REST
 
REST Command Line Interface (CLI) helps you CREATE or DELETE a REST application.
Enter an application name or (L)ist all REST applications (L): PcConRest
REST application not found: PcConRest
Do you want to create a new REST application?

I have been struggling with a docker run command that kept crashing, the error message was too generic to point me to the right direction.

Since the container is shut down after the failure, I was unable to login to it in order to figure out the problem.

I had to run the container in a way that I'll be able to log into it before it crashed, so I found the adding  -u false prevents the docker run command to run the iris session IRIS and the container stayed up and running.

Hello everyone,

I am working in the HealthShare, and I need to check some modification during a period of time in the records of a patient. But I don't want to use HealthShare managment portal, I want to create some querys because are many records of patient. I tried to find the Globals or Tables that are used by Iris in the Record History function. ChatGPT helped me, saing that the table is HS.IHEX.RecordHistory and the global ^HS.IHEX.RecordHistory, but I didn't find any data in the global or table. Can someone help me?

Last Friday November 17 suddenly ran into an error where ZPM would issue an error saying:

ERROR! Object open failed because 'Name' key value of 'xx' was not found

I googled but found no specific help. Step by step I was able to conclude that:

1. This is the error message for error 5770, also known as $$$KeyValueNotFoundOpen.

2. In objectscript, this error can be raised by calls to NameOpen, where 'Name' is the first quoted part in the error message.

3. The error status is raised when there is a call to ##class(yy.zz).NameOpen("xx", , .sc) where yy.

Hello,

I am trying to use the %ToJSON method on my dynamic object, calling it with a "DO" and not passing in outstrm parameter.

We are trying to avoid MAXSTRING errors that we get with some of our abnormally large messages.  In order to do this, I am trying to update my code to not call the socket's "Write" method after converting the dynamic object to a JSON string using the %ToString method's output.

We are running Batch job in scheduled task and the messages are picking in single session and it is not easy to trace the record.

I used the Set ..%SessionId= "" at before sending the message to BP but I see the session Id is '1' created for each message.

Is there anyother way to create new session for each message sending to BP?

Thanks,

Hello, I tried to read a XML list from a web service into a response class by creating a custom collection subclass as described in this documentation page

Here's the XML file I am trying to read:

<Suppliers>
    <Supplier>
        <row>1</row>
    </Supplier>
    <Supplier>
        <row>2</row>
    </Supplier>
</Suppliers>

And the different classes I defined to project the XML into:

Class App.Messages.GetSuppliersResponse Extends (%Persistent, Ens.Response)
{
Property Suppliers As App.Objects.Suppliers;

Method Deserialize(stream as %Stream.

InterSystems FAQ rubric

If you need to migrate your server for some reason, you can reduce the setup work by copying configuration information from the pre-migration environment to the post-migration environment.

The following setting information can be migrated.

• iris.cpf
• SQL gateway settings
• web gateway settings *Note 1
• user-created routines etc. stored in the IRISSYS database *Note 2
• security settings
• task settings

Note 1: If a password has been set, only the password needs to be reset manually.
Note 2: Preferred connection server settings such as ^%ZSTART, ^ZMIRROR routines, etc.

In this article,  I walk through the %JSON.Adaptor class. This class is extremely useful in exporting data into serialized JSON and importing the JSON objects and saves into class object.

I'll start with the %JSON. Adaptor parameters. The parameters are crucial part of the JSON import and export operations.

If your property name is not the same as the actual JSON key name for export to external or load the data’s into object through import, you should use the %JSONFIELDNAME parameter to define the alias name.

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.

In VSCode using the InterSystems extensions, I now have an almost working environment where routines can be created or modified on disk and these are pushed to the developer's IRIS instance.

One issue I'm finding whilst testing is that if I rename or delete a routine from disk, the change isn't pushed to IRIS and I can't work out how to make this happen.

This means that a developer can have renamed or deleted a file on disk, but can still call functions within the renamed/deleted routine within the IRIS instance and not experience any NOROUTINE errors.

I am trying to pull out something similar to an HL7 date/time stamp in a custom zen page , in a javascript code section.

var d = new Date();

(Fri Jan 12 2024 16:58:30 GMT-0500 (Eastern Standard Time)

but,
var year = d.getFullYear();

d.<formatcmd>  doesn't seem to work.  (d.getmonth, etc.)

Is there and date formatting I can use inside a javascript routine?

The company I work for have a repository for one of our products which already contains both InterSystems and non-InterSystems source code. I'm in the process of trying to migrate us over to using VSCode to edit the InterSystems source but am stuck on some issues surrounding the files on disk and the routines in the IRIS instance.

The folder structure inside the repo is \appname\src\database. Directly underneath the database folder is all of our InterSystems source code. If I add a new routine to the root of the database folder called ROUTINEA.

Hi,

I have this IRIS server, NODE1. NODE1 is a Linux server running IRIS.

To connect to IRIS on this server I:

From my PC ssh (via putty) to NODE1

From the putty session, I, "iris session <iris instance>"

I was hoping to use iristerm on my PC:

I put NODE1 into IRIS Server Manager

From my PC, I, "iristerm /server=NODE1"

I get this error message:

"TCP connect() failed"
How to get this to work?

I understand that iristerm tries to connect to the server first using telnet then connects to the IRIS running on ths server. Correct?

The 2023.1.3 extended maintenance releases of InterSystems IRIS, InterSystems IRIS for Health, and HealthShare Health Connect is now available. It provides bug fixes for any of the previous 2023.1.x releases.

You can find the detailed change lists / upgrade checklists on these pages:

• InterSystems IRIS
• InterSystems IRIS for Health
• HealthShare Health Connect

How to get the software

The software is available as both classic installation packages and container images.  For the complete list of available installers and container images, please refer to the Supported Platforms webpage.

When using VS Code to develop with Object Script, the Server Credentials prompt for connecting to the IRIS instance is happy accept a blank for UnknownUser. See screen shot:

From here VS Code happily connects to the IRIS instance using unauthenticated access. But the standard VS Code "Go To Definition" appears to do nothing. Whilst looking through the documentation I found that in the Language Server extension, there is a setting to output verbose trace details.

When I do $TRACE("message") I can see the message on the message viewer. However, I don't know where to find messages generated from $$$sysTRACE, and I haven't found anything about it in the documentation.

Do you know where I can find it?

⏯ Working with InterSystems IRIS Cloud SQL

Hello, community!

Ihave been tinkering around with Flutter lately and, as a result, came up with some apps that can use Firebase as a database. When I realized there was an available Python library, I felt the urge to create something for InterSystems IRIS that would communicate with the Firebase RealTime Database and perform CRUD operations. Later, I stumbled upon the following idea from Evgeny in the portal:

https://ideas.intersystems.com/ideas/DP-I-146&nbsp;

That is when  I got down to work!

Are you curious to see my findings? Then buckle up because we’re about to take off!

What comes to the data platform (not the user facing application) most of the the events of interest/required are available as predefined system audit events in audit log - out of the box. They just need to be enabled.

InterSystems has decided to stop further development of the InterSystems IRIS Natural Language Processing, formerly known as iKnow, technology and label it as deprecated as of the 2023.3 release of InterSystems IRIS. InterSystems will continue to support existing customers using the technology, but does not recommend starting new development projects outside of the core text exploration use cases it was originally designed for.

Hello everyone,

I am new to Deepsee (BI intelligence) concepts in IRIS. I am looking for a solution of below question

Question: We have a server where we are currently storing archive PDF reports of our application.

We want to add and view these archive reports (PDF format only) in dashboards. Is there any way we can do this? Or any article which can help us performing this task.

Thanks in advance!!
