#InterSystems IRIS

One of the most common needs of our clients is the creation of REST services that allow access to the information present in IRIS / HealthConnect. The advantage of these REST services is that it allows the development of custom user interfaces with the most current technologies taking advantage of the reliability and performance of IRIS in the back-end.

In today's article we are going to create a web service step by step that will allow us to both store data in our database and later consult them.

InterSystems is committed to providing a high quality developer experience including a great IDE (Integrated Developer Experience). For the past several years we have been evolving Visual Studio Code's ObjectScript tooling in parallel with our long-standing IDE, InterSystems Studio. There have been over 46,000 downloads of the VSCode-ObjectScript plugin, and the feedback from developers is that this is a great developer experience, and now superior to InterSystems Studio.

With our 2023.2 release we are deprecating InterSystems Studio (deprecated designates a feature or technology that

How does IRIS know which local adapters are available to populate in an Inbound or Outbound TCP Adapter Object? We recently moved from HealthShare Health Connect 2018.1.3 to IRIS HealthShare Health Connect  2022.1. When we migrated we moved the VIP over to the new box and set it at the hardware level.

how can we track logs of our rest api that we create in web applications. As i am running it on local system.

I am trying to write the module.xml for a package that creates a web application associated with the %SYS namespace.

I didn't find a way of specifying that the CSPApplication tag should create the app for a specific namespace. It apparently gets set up to use the namespace in which the package install command gets run. This contrasts with how an installer manifest works, where the <CSPApplication> tag is put inside a <Namespace> tag.

So I wondered if I could make my package fail installation if the current namespace isn't %SYS.My package doesn't need to load anything, only create the web app.

Hello!

I would like to find all classes not up to date in a namespace programmatically.

With IRIS Studio, we can see the single "+", but I don't know how to do that with a script.

Set sql = "SELECT ID, Name FROM %Dictionary.ClassDefinition WHERE NOT ID %STARTSWITH ?"Set params($Increment(params)) = "%"Set tResult = ##class(%SQL.Statement).%ExecDirect(, sql, params...)

If (tResult.%SQLCODE'=0)&&(tResult.%SQLCODE'=100) Set sc = $$$ERROR($$$SQLError, tResult.%SQLCODE, tResult.%Message) Quit sc

While tResult.%Next() {
    // if class not up to date ??

Intro

If you ever wondered how to debug some requests that are being made to or from IRIS, well here is a little tutorial on how to do that.

During a complex project, usually you get the specifications and implement the communication between IRIS and other things based on that. But from the paper to the real world there's usually a huge gap and you need to know why you are receiving an error on a parameter, on a header, you are not receiving the data and so on.

If the connection is a plain http connection there's no problem, you can always fire up tcpdump and capure the traffic, but what about

 1. Export API

a. Use $system.OBJ.Export() to specify individual routines to export. For example:

The format to specify is routine name.extension, and the extension is mac, bas, int, inc, obj.

Errors during export are stored in errors.

See the class reference %SYSTEM.OBJ for details on $system.OBJ.Export().

b. Use $system.OBJ.Export() even when exporting with wildcards. For example:

*Before version 2008.1, use $system.OB

Last week at the InterSystems Global Summit, we announced our new Foreign Tables capability, which was introduced as an experimental feature with the 2023.1 release earlier this year. We're now inviting you to join the Early Access Program for Foreign Tables and kick the tires on this new capability, so you can let us know whether it suits your needs and what capabilities we should prioritize next.

So what are Foreign Tables, really? -- In case you don't have the time or popcorn to watch this nice overview video, Foreign Tables help you project data to IRIS SQL that is physically stored

InterSystems has corrected a defect that causes increased process memory usage.

Specifically, the increased consumption of local process partition memory occurs when executing $Order,  $Query, or Merge on local variables.  While this will have no detrimental impact for most running environments, environments that support a large number of processes or closely limit Maximum Per-Process Memorycould be impacted.  Some processes may experience <STORE> errors.

The defect exists in 2023.1.0.229.0 but it is reposted as 2023.1.0.235.1 with the fixes included, to expedite the correction without clients

Who has never been through in the following situation:

I have an application/global configuration that is not and cannot be mapped to a class, but it is necessary to provide a stored procedure so that a report tool using ODBC/JDBC or even using the resultset of IRIS itself, can access the data and generate the report.

In IRIS we have a functionality that allows us to create a query that can be accessed internally and also be exposed as a stored procedure, with our own logic. That functionality is Custom Class Query.

To define a Custom Class Query we must follow these steps (which we can make

Hi Community!

Just want to share with you an exercise I made to create "my own" chat with GPT in Telegram.

It became possible because of two components on Open Exchange: Telegram Adapter by @Nikolay Solovyev and IRIS Open-AI by  @Kurro Lopez 

So with this example you can setup your own chat with ChatGPT in Telegram. 

Let's see how to make it work!

We often get questions about recent and upcoming changes to the list of platforms and frameworks that are supported by the InterSystems IRIS data platform.  This update aims to share recent changes as well as our best current knowledge on upcoming changes, but predicting the future is tricky business and this shouldn’t be considered a committed roadmap. 

With that said, on to the update…

Hello,

I would like to get a list of all globals that have been read or written during a given context. In Portal, there are counters in dashboard that give the number of read/write to globals in general.

What I am looking for : 

- some handler (eg: like $ZTRAP) that will be called everytime something is read/written to a global.

- to activate a "global log mode" in Portal that will dump some information to a file (like ^ISCSOAP for SOAP requests).

I understand this is something that can considerably slow down IRIS, but it's intended to be used only for debbuging and under no load.

As last resort,

I have a repository on github. I wanna setup that repo into my local IRIS instance and also I want to work on different branch and commit those back to the same repo. 
Please help me through this. 
I also have a .DAT file which i think contains code and data and not .git folder. So how can i sync that to my git repo for further development.

how can i use git for versioning while working in IRIS. 
I am having directory that i created while working in iris. How can i manage version control using git in this case.

Is it possible with vscode terminal or with a normal terminal in mac.

Hi there,

Please, could anyone tell me how can I set up VSCode terminal to IRIS terminal? I already saw this working in a video with docker version from IRIS Community. I have the Intersystems Extension Pack and IRIS Community locally installed.

Thanks

Hi folks!

Those who actively use unittests with ObjectScript know that they are methods of instance but not classmethods.

Sometimes this is not very convenient. What I do now if I face that some test method fails I COPY(!) this method somewhere else as classmethod and run/debug it.

Is there a handy way to call the particular unittest method in terminal?  And what is more important, a handy way to debug the test method?

Why do we have unittest methods as instance methods?

Since SELECT ... FOR UPDATE is implemented in many RDBMS as a method of explicit row lock acquisition, I think there are many cases where this function is used.

This syntax is not an error for InterSystems products, but it does not acquire row locks as expected.

This article will show you how to achieve equivalent functionality.

DECLARE CURSOR C1 IS
SELECT Name FROM Person WHERE Name LIKE 'A%' FOR UPDATE
OPEN C1
LOOP FETCH C1 INTO name
