Hey Community,

Here is a digest of the Developer Community videos on InterSystems Developers YouTube Channel in April 2024:

Hi, 

I'm new to IS and the HL7 transformations using the DTL.  I need some clarification on the foreach action.

I want to iterate over IN1 segments, and output only segments that contain certain allergy types in IN1-2 with foreach.  Inside the foreach block, I check for allergy type "FA" in IN1-2 and, if found, send the segment with only the required fields (fields #1, #2, #3, and #5 to be exact).  Please see the foreach block below:

I'm puzzled how come I'm getting field repetitions in the fields I populate within the foreach block  Here are the AL1 segments in the source message

AL1|1|DA~FA|NO

Introduction

Accessing Amazon S3 (Simple Storage Service) buckets programmatically is a common requirement for many applications. However, setting up and managing AWS accounts is daunting and expensive, especially for small-scale projects or local development environments. In this article, we'll explore how to overcome this hurdle by using Localstack to simulate AWS services. Localstack mimics most AWS services, meaning one can develop and test applications without incurring any costs or relying on an internet connection, which can be incredibly useful for rapid development and debugging. We used ObjectScript with embedded Python to communicate with Intersystems IRIS and AWS simultaneously.Before beginning, ensure you have Python and Docker installed on your system. When Localstack is set up and running, the bucket can be created and used.

Did you know that you can get JSON data directly from your SQL tables?

Let me introduce you to 2 useful SQL functions that are used to retrieve JSON data from SQL queries - JSON_ARRAY and JSON_OBJECT. 
You can use those functions in the SELECT statement with other types of select items, and they can be specified in other locations where an SQL function can be used, such as in a WHERE clause

The JSON_ARRAY function takes a comma-separated list of expressions and returns a JSON array containing those values.

SELECT TOP 3Name,
JSON_ARRAY(%ID,%TABLENAME,UCASE(Name),Age,Home_State) "JSON data" 
FROM

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.

I am trying to locate a method that would allow me to differentiate between InterSystems preinstalled/system namespaces and "our own" namespaces. I am interested both in Cache and Iris answers if they are different. Yes, I can list what to disregard, like if not HSLIB or if not DOCBOOK but hoping for a more universal and elegant answer.

In our previous article we presented the general concepts as well as the problem that we wanted to solve by using the task engine integrated in InterSystems IRIS, in today's article we will see how we configure an interoperability production to provide a solution.

Workflow Engine Configuration

First we are going to define the roles of the tasks that we are going to manage, in our example we are going to define two types:

• AutomaticBloodPressureRole: to create automatic tasks that will have no intervention from the user.
• ManualBloodPressureRole: to create those tasks that the user must manually

Hello community!

As you know, InterSystems will be one more year at the J On The Beach conference, which will take place from May 8 to May 10 in Torremolinos, Málaga.

And we're especially looking forward to seeing you because we know you're going to love what we have in store:

BPL from 10,000 feet

BPL stands for Business Process Language.
This is an XML format for describing complex information orchestration interactions between systems.
InterSystems Integration engine has for two decades, provided a visual designer to build, configure, and maintain, BPL using a graphical interface.
Think of it like drawing a process flow diagram that can be compiled and deployed.

An example: Make a cup of tea

BPL components are added to Integration productions like any other built-in or custom business component.

Test example input and output

There can be a mixed reception to using BPL

I have the JSON message below. I am struggling with parsing the data in the OtherProcedures section. That section can be null, or have from one to many other procedures.

After upgrading your system, you may receive the error below when you try to open the Management Portal:

ERROR #5001: Server version of object does not match version sent from the client: %ZEN.Component.vgroup

This error is caused by outdated information remaining in your browser's cache.

You can resolve the error by clearing your browser's cache.

Hi Guys,

I never ran a Compact & truncate process before and we do have a 4.6TB database with 1.9TB free space available that I would like to recover 

but when trying to compact first it did ask me to target in MBs and not sure what this is, does it mean that I need enough space to move all my 4.6TB database to ? and given that system is running live does the Compact or Truncate process stop or affect our system from been used from our clients and any idea how long such process would take to finish (minutes or hours) ?  

Thanks

Hi Guys,

My Cache.dat has a expanded a lot and some globals occupy a lot of disc space with just junk data so I would like to kill some globals and shrink the cache.dat file because I'm running out of disk space?
So is there a way to do that without having to do it through the Truncate & Compact databases?

Thanks  

Hi, I hope this post helps.

The bottom line: MAXLEN is relevant mostly for odbc/jdbc connections and you need to specify an appropriate value within your  tables (classes), otherwise the data might be truncated when you query it, or even fail when you try to insert data.

Long story:

the sql GUI in the portal is very lenient in reference to the MAXLEN  , for example you can insert data into a table where there is data longer then the size of a column, if you're using fhir sql the columns in the tables are mostly MAXLEN =50 even if there is much larger data, additionally if you create a table from

Hi Guys

Two of the HC servers I manage (a mirrored pair) have lost the ability to debug code, and I am unsure as to why this has happened. Clearly something has changed, as the other three are working just fine.

When I select a Class Method as debug target, add a few break points and run it, I get the following Output

Debugger executing '##class(InPhase.Test.CanUpdate).TestBIU()'

⏯ Introducing Smart Data Services @ Global Summit 2023

A few weeks ago I posted an announcement about a JavaScript-based interface for our mg_web WebServer interfacing addon module.  mg_web isn't just restricted to use by JavaScript developers though.  Many readers will be ObjectScript developers who are more used to using CSP as their web gateway.  Some may even have much older legacy WebLink-based applications (and be wondering how to support them given that IRIS does not support WebLink).

This article aims to provide some more information on mg_web and to explain why it's worth a look for ObjectScript developers.

The first thing to understand is

hi there,

I recently created a shell script to run the integrity check.

I used this as reference - Introduction | InterSystems IRIS Data Platform 2023.3

I found the example from above url having a line - "

kill ^IRIS.TempIntegrityOutput(+$job)

it isn't working when I used in a script. it returns the pid of my iris session instead.

I had to simplify the example to run following lines instead - 

Do CheckList^Integrity(,,,,5)
do Display^Integrity(,1,)
 

script runs fine and can see integrity check results as expected.

however, the output seems cumulative, and output includes all historical run results as

Technical surprises using VECTORs
>>> UPDATED

Building my tech. example provided me with a bunch of findings htt I want to share.
The first vectors I touched appeared with text analysis and more than 200  dimensions.
I have to confess that I feel well with Einstein's 4 dimensional world.
7 to 15 dimensions populating the String Theory are somewhat across the border.
But 200 and more is definitely far beyond my mathematical horizon.
