If one of your packages on OEX receives a review, you get notified by OEX only of YOUR own package.   
The rating reflects the experience of the reviewer with the status found at the time of review.   
It is kind of a snapshot and might have changed meanwhile.   
Reviews by other members of the community are marked by * in the last column.

I also placed a bunch of Pull Requests on GitHub when I found a problem I could fix.    
Some were accepted and merged, and some were just ignored.     
So if you made a major change and expect a changed review, just let me know.

If you start with InterSystems ObjectScript, you will meet the XECUTE command.
And beginners may ask: Where and Why may I need to use this ?

The official documentation has a rich collection of code snippets. No practical case.
Just recently, I met a use case that I'd like to share with you.

The scenario:

When you build an IRIS container with Docker, then, in most cases,
you run the  initialization script  

iris session iris < iris.script

Being impressed by the graphics of the package GBLSizeMonitor  from @Ashok Kumar T 
I ask for his help, and this is the result of our cooperation.

As in the previous package, all is running from a CSP page.
And it is all classic CSP written with InterSystems ObjectScript, JavaScript, HTML
Besides the graphic, you also get concrete numbers freshly collected from your local
instance or from remote instances that also installed the package. 

The final result

To better understand Streams in IRIS I'll start with a short

History

In the beginning (before IRIS), there was just basic access to external devices.
The 4 commands OPEN, CLOSE, READ, WRITE still work and are documented 
by  Introduction to I/O in detail.
Especially for files, this is a direct access to your actual file system.
You have to take care of any status or other signal in your code.  
Also, any code conversion or similar is up to you.

Finishing my previous example for multiple IRIS instances, I tried
to compose a local single instance version.  The step from the external
Python app to a version using embedded Python seemed to be obvious.
This was a wrong assumption, as some Python libraries just refused installation
into my local Windows-based environment.

The article was motivated by the 2025 September Article Bounty
***************************************************************

The principle of Docker is just convincing to me.

  • Get a sandbox where you play and try whatever you want/need to do
  • Once done. You drop it without leaving traces in your working environment

This was the technical base for me to run about 700 reviews in OEX 
with almost no side effects  (except those caused by myself).

For beginners, I'll start with straight pure IRIS, no *health, *ML, *whatever

If you are investigating complex structured Globals this can become
a rather boring typing exercise. Different from Global Explorer in
System Management Portal Global-Inspector allows a kind of drill-down
to dig deeper and deeper by subscript levels.
You also have the option to see the stored content or to show only
the subscript structures.
Globals storing SQL Tables are probably not so thrilling, but in SYSTEM
space you find real trees with completely different branches and twigs.

Global-Inspector can run in browser or from terminal command line.

Host Variables are a rather common programming feature in many implementations of SQL. 
A recent question in DC made me aware that in IRIS, Caché, Ensemble, ... 
host variables just exist within embedded SQL

>  You can supply host variables for Embedded SQL queries only. <

Related examples are included in the available Documentation

This is a description  for a workaround if you don't / can't use embedded SQL.

Question Robert Cemper · Feb 1

Import from DC-PT, @Edilson Eberle Carvalho 

We have some *.mac routines and we need to preserve their source,
as these routines have intellectual authorship and can only be used per session
with the right to use (they cannot be viewed or edited).
The question: how to keep only the routine object in the IRIS namespace,
without interfering with its execution?

I recently met an ages old issue related to code maintenance:

  • You have access to your IRIS server just over ODBC/JDBC
  • no VSCode access, no Studio access
  • no (Web-)Terminal access

But you need to take a look on Classes or Routines or Globals !!
Anyhow SQL is your friend.

  • First you need a simple table as temporary text store.
CREATEGLOBALTEMPORARYTABLE  arcc.txt (line VARCHAR(32000))

Not a thrilling action.

  • Next you export your code to local file and import it to your table

In principle I'm looking in forward direction.
Though from time to time it makes sense to turn back and see the full path taken.

  • I started reporting my reviews almost 4 years ago. 
  • I just reviewed packages that I could reproduce in my environment.
  • Skipping items beyond my physical or mental capacities.
  • So some great packages might not be present here
  • But I added also 139 contributions of other reviewers
  • It was anyhow a total of  769 reviews published
  • Meeting over this time 191 different authors

During testing the added Multi-Namespace feature I met a challenge
that required intervention. This simple request created 1000 lines of output.

USER>do^rcc.find
----------------
 
enter search string [$ZU] <blank> to exit:
          Verbose? (0,1) [0]:
          Force UpperCase? (1,0) [1]:
 
enter code type (CLS,MAC,INT,INC,ALL) [ALL]:
 
select namespace (ALL,%SYS,DOCBOOK,ENSDEMO,ENSEMBLE,SAMPLES,USER) [USER]: all
  • As for the verbose variant you my run a log on your terminal to keep the result in details
  • though a real summary was still missing.
