#InterSystems IRIS

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 ab

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:

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 els

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 clie

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 m

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!

Hi folks!

Is it possible to use Environment variables for production settings?

E.g. I have a telegram adapter for which I need to setup token(part of the production below):

Is it possible to point the expression for Token setting "some-telegram-token" which will

Is there not a way to use the Red Hat 8 install package to do an `irisinstall`? If not, how does one get the IRIS Community .tar.gz file for "Red Hat 9"?

I am having code like this,

set args = []

Instead of placing args[1],args[2] etc into the above I want to pass the whole args at a time if it possible.?

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.

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　
... show name
... EXIT the LOOP when finished
END LOOP
CLOSE C1

The above SQL statement can be substituted with the followi

Using the Config.Configuration class and SYS.Database class methods, you can create and register a namespace database from the terminal.

Below is a series of execution examples that create database file /CacheDB/AAA/cache.dat and register database AAA and namespace AAA in the configuration file (cache.cpf).
* Execute in the %SYS namespace. *

* Make sure that this script runs as the user  that is used for all IRIS processes to ensure that the directory has appropriate ownership and permissions *

Note that some of these features or improvements may not be available in this current developer preview.

Another important topic is the removal of the Private Web Server (PWS) from the ins

I am curious as to why one would use lookup tables, and what would be the best practices regarding them. We have two namespaces, and we would like to use the lookup table in each one. But, there's no clear outline of when to use them, and what are the best ways to use them?

Any help is appreciated.

Recently I needed to restore a version of a production class, which was overwritten by compilation and running UpdateProduction. As the correct version was unavailable in the source control, I used journals to restore the data. Journals store a plethora of information about what's happening in the system and are quite a powerful tool. This article explains how to work with journals to extract the data you require.

how can i import IRIS.DAT file into iris system. I am told that it is database file that will be import into iris db.

Unlike IRIS Studio have compile depended classes feature. How to achieve this in mac on Vscode.

As a former JAVA developer it has always been a challenge to decide which database was the most suitable for the project we were going to develop, one of the main criteria I used was their performance, as well as their HA configuration capabilities ( high availability). Well, now is the time to put IRIS to the test with respect to some of the most commonly used databases, so I've decided to create a small Java project based on SpringBoot that connects via JDBC with a MySQL database, another of PostgreSQL and finally with IRIS.

We are going to take advantage of the fact that we have Docker ima

Ran into an issue with our upgrade from HealthShare Health Connect 2018.1.3 to IRIS HealthShare Health Connect 2022.1, that I thought I would reach out about, I already have a ticket open with WRC and started a chat on Discord. We have a couple of MS SQL tables that I have setup as Linked Tables within Cache to query NPI, Patient Account Information, Visit information, etc... When we upgraded last week we found that within a day or even a half a day that we were having problems with our JDBC connections.

Upon investigating with WRC we were able to track it down to our Queries against Linked T
