#InterSystems IRIS

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.

Hi folks!

We have a bunch of templates on OEX that provide a handy foundation for building a particular application with IRIS. And the basic principle of each and every template is that we take vanilla IRIS images, load code, and files into the image using Dockerfile, and create a new docker image as a solution. And then we develop running this image and rebuilding it when returning to development.

Some developers ask me why we need to build the docker image to work with the code. Indeed, if at the end of the day I need to develop a ZPM package and not a docker image why don't run the vanilla image and load the code and everything in it?

The problem I have with the building image approach is that often I can wait a lot to build an image and it fails on some Objectscript problem in the source that I cannot fix as the image is not building. and

Any thoughts? How do you develop with docker?

The use of Source Code Control systems in development is important. And there are a few systems known in the world, like GIT, SVN (Subversion), Perforce, Mercurial. Where the most popular nowadays is the git. Using it is very useful in many cases, but mostly it depends on the code as text, which can be compared between commits, branches, or versions of releases and so on.

Monitoring Platforms

With System Alerting and Monitoring (SAM) being deprecated in the near future..

  • What is everyone's go-to for Monitoring IRIS?
  • What is readily available?
  • What is the cost surrounding it?

Just trying to get ideas floating around of what we might need to start looking at to satisfy IT leadership.

Thanks

Scott

In the past, I've created custom SQL operations, but now I had something trivial to do, so I decided to take EnsLib.SQL.Operation.GenericOperation out for a spin. There's no example in the docs, so it was a little tricky. Here's what I ended up doing:

In my external database, I have 'mytable' with two fields 'id1' and 'id2'. Here are the pertinent Business Operation settings:

The idea for iris-user-manager

I want to deploy IRIS apps running in containers in Kubernetes with user accounts configured.

I have a %ZSTART routine which looks for an XML file with Users export data and if the %ZSTART routine finds this file, it imports it. This Users export data can be obtained by running a class method.

I have defined a task which can be scheduled or run on demand. This tasks imports user data from an XM file.

In Kubernetes I can provide a ConfigMap to stage the Users data for the %ZSTART routine.

Is anyone using the IPM client (e.g., running commands like zpm "install somepackagename") on an IRIS version earlier than 2022.1?

We're thinking about raising the minimum supported version so we can use Embedded Python in IPM. I'm curious if this would impact anyone. Of course, you'd be able to continue to use an earlier version of IPM.

I'm not sure what the purpose of this is, but the Management Console causes the browser to refresh periodically. If you're in a form or an editor such as the DTL or Routing Rule editors, you may lose work unless you save frequently. This did not occur in Caché 2018 and earlier releases.

I've had a couple of incidents where I've created a number of rules in the DTL editor, answered the phone or stepped away for a few minutes, then come back to find any work since the last save erased.

I've noticed this in both 2019 and 2020 releases of IRIS.

Heads up!

I am sure I came across this in the past with Cache and just saw this again in IRIS.

When rebuilding or swapping a DAT file for a database it retains the Resource of the DAT file, not the Resource of the Database it is being used for.

For instance, if I have a local Database called APP with a resource %DB_APP and I want to refresh the data from another Database called TEST that has a Resource %DB_TEST I can just copy the DAT file from the TEST folder to the APP folder.

AWS Batch

Has anyone tried AWS Batch with InterSystems IRIS docker images?

I have a noninteractive workload (but it requires internet access from the job to deliver results), so I'm considering using it as a simpler alternative to ECS since Fargate backs both, and that's enough for my use case.

I wonder if anyone tried and cares to share the results, issues, cfn templates.

Hi Developers!

Want to raise security discussion today!

Let's discuss how InterSystems security for applications works. In general, the concept is clear: we have Resources (what to protect), Roles which combine a set of privileges and accesses to Resources and Users which can have this or that Role.

But there is also a concept of Application which also could have a Role.

So you either provide a Role for a User or for an Application.

What do you use in production? What is your strategy and why? Pros, cons?

When overwriting the Read method (that has a %CacheString return type) on a new class that inherits %Stream.FileCharacter class, returns an error about incorrect return type, must be Binary, even if it matched the real signature.

Looking at the compile global information we can see:

^oddCOM("%Stream.FileBinary","m","Read",42)="%Library.Binary"

After further investigation we realise that there is a generator method looking at the OdbcType class definition.

Setting LONGVARCHAR results in:

^oddCOM("User.CStream","m","Read",42)="%Library.String"

If anyone has a custom checklist of tasks that must absolutely be done when doing this upgrade to make sure everything is included and nothing is lost or destroyed, we would greatly appreciate it? We have the generic checklist provided on the support websites but we run custom build classes, ftp, tcp-ip, batch, etc.

Thanks,

Jonathan Harris

Currently, the SQL privileges (SELECT, INSERT, UPDATE, DELETE) are managed at the tables level, which can be very tedious when you have to administer many roles in an organization, and need to keep them sync with a constantly evolving data models.
By managing privileges at the schemas level, will allow to give SELECT and other DML privileges to *all* or *several schemas* to a role|user, fixing the need to manually synchronize the new tables|views to the roles.

Converting from 2018 to IRIS 2024

Hi Guys,

I'm new to IRIS and I'm converting from Ensemble 2018 to IRIS but not sure how to convert my cache.data file to IRIS.dat, I copied my cache.data to a new folder then went to IRIS management portal and created a new database and specified the directory to where my cache.data and saved and I thought that IRIS will automatically convert cache.dat to IRIS.dat but instead it created a new empty IRIS.dat, I guess I was wrong in my assumptions !?

Hi guys!

Suppose you developed a tool, framework, library on InterSystems ObjectScript for InterSystems Data Platform, share it via Open Exchange and want people to install it.

What is the best strategy if it is a library and supposed to be called from different namespaces?

Here are the following thoughts:

1. Tool's developer should be able to use globals to read/store data the tool needs.

2. Tool's consumer should be confident, that the thing he/she installs will not harm the application's data.

3. A tool should be callable from any application's namespace.

4. Tool's installation(in general) should not request manual security changes (e.g. grant the write access to IRISLIB) and %YourClass is not an option.

5. It's easy to uninstall the tool - just delete the namespace/database (maybe delete some web-apps too).

Has anyone had any success reading barcodes from PDFs or images in a Cache/IRIS application? I've been looking at some possible solutions for this, including the open source ZXing libraries. I know we have the ability to create them in Zen and Intersystems Reports, but as far as I know, there's nothing built in to actually read data from a barcode. If anyone has suggestions on how to go about this, I'd love to hear them.

$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! 🤩

IRIS vs Other integration engines

Hello All,

I have been using IRIS / Ensemble for over a decade and appreciate lot of it's functionalities and features, however besides having a UI of 80's era (which doesn't bother me), what I believe where IRIS is lacking is lack of out of the box connectors (services/operations).

If we look at IRIS's competitors for eg Mulesoft, Talend, Boomi they all have hundreds of pre-built connectors for major applications like Salesforce, SAP etc and cloud services like Azure, AWS etc to store and retrieve information and data.
