I'm looking for some simple heuristics to estimate the size on disk of a database based on average size of messages, number of messages per day and purge frequency. The purpose is for estimation of disk space requirements.

Clearly this is a how long is a piece of string question but for example, if you have a simple HL7 routing production that does nothing but process HL7.It receives 10,000 HL7v2 messages per day (all approx 1kb on the wire) in a single service, passes them to a single router and outputs to a single operation.

Hi,
I want to automate a menu based program for which I don't have the source

If I run it interactively I do this:
do ^<program>

It presents a menu and then you can go down further menus

Based on the selection it may ask for answers to other questions.

Is there some way I give the program a "response" file?

If not would I be able to use I/O redirection for this task?
Inputs would come from a file.
Output should go to the terminal (so I monitor how far the process has gone)

I have seen some examples of redirection code and it seems quite complicated.

IRIS runs on a Linux server

I have been trying to get to grips with the new dot Net Gateway used in IRIS as the import of the DLL to construct proxy classes is no longer supported in IRIS I have a third party DLL that when I try to instantiate throws an error complaining about the class not instantiated as it does not support parameterless constructor .I am using this new 

set gateway = $system.external.getDotNetGateway()
do gateway.addToPath(myPath_"\DotNetGatewaySamples.dll")

I would like then to instantiate my class which has a constructor that requires a parameter, how am I suppose to achieve that and if there is a

Hi All,

How can I customize the file path of my FTP outbound adapter.

I have a custom business operation that extends "EnsLib.FTP.InboundAdapter", in which I need to update the file path of my FTP server location.

Hello everyone

For those interested, here is an implementation example I used in one of my projects to interoperate with MongoDB using the pymongo package.

iris-mongodb

Interoperates with MongoDB (via pymongo package) with InterSystems IRIS (including outbound adapter)

Remember to import pymongo package.

implementation example for testing here

NAMESPACE> do ##class(custom.python.pymongo.test).TestMongoDBCrud()

for interoperability, use the following adapter in your business operation:

Parameter ADAPTER = "custom.python.pymongo.outboundAdapter";

Parameter INVOCATION = "Queue";

Query example:

///

Long shot but is there a way to see which user created an Operation (for example) in Iris?

Anyone know how to subtract three hours from $ZDATETIME($HOROLOG,3)?

If $ZDATETIME($HOROLOG,3) returns 2025-01-30 10:17:04, I would like $ZDATETIME($HOROLOG,3) - 3 hours to return 2025-01-30 07:17:04

What is the recommended library for converting documents to pdf. Any suggestions welcome has anyone out there had a use case where they had to convert documents to pdf .What worked for them .I have asked WRC for the best practice and they have recommended that may be  a sale engineer might have an answer to this .

Hello everyone!

I have set up an EnsLib.REST.GenericService with an  EnsLib.HTTP.InboundAdapter which forwards the http requests received by a web app to my Business Process. 

I would like to parse HTTP multipart/form messages I am receving and be able to iterate over the various fields within the request body, accessing its content type and the content itself.

As far as I understand I should use the %Net.MIMEReader class which should return a list of %Net.MIMEPart, one for each field within the request. However if I do : 

Set mimeReader = ##class(%Net.MIMEReader).%New()
Set sc =

Hi Everyone!

The Certification Team of InterSystems Learning Services is currently developing an InterSystems ObjectScript Specialist certification exam. Earlier this month we reached out to our community for feedback that will help us evaluate and establish the contents of this exam. We are still currently accepting responses and would love to hear your feedback!

Please note that this is one of two exams being developed to replace our InterSystems IRIS Core Solutions Developer exam. You can find more details about the other exam, InterSystems IRIS Developer Professional exam, here. 

How do I

The IKO will dynamically provision storage in the form of persistent volumes and pods will claim them via persistent volume claims.

But storage can come in different shapes and sizes. The blueprint to the details about the persistent volumes comes in the form of the storage class.

This raises the question: we've deployed the IrisCluster, and haven't specified a storage class yet. So what's going on?

You'll notice that with a simple

kubectl get storageclass

you'll find the storage classes that exist in your cluster.

Since .Net has a unified package manager system (Nuget.org) why doesn't Intersystems create and add a nuget package (.nupkg) containing the InterSystems.Data.IRISClient.dll file.

This would make it easier for external .net developers to obtain the package for creating tools and/or applications that utilize Iris/Iris4Health

Can  Intersystems create a nuget package?

InterSystems worked closely with the Red Hat Insights team to implement a curated set of recommendations for system administrators to ensure the best experience running InterSystems IRIS on Red Hat Enterprise Linux (RHEL). Included with all RHEL subscriptions, the Insights service proactively identifies potential issues with monitored platforms and applications running on RHEL. Through our joint collaboration, Insights now watches for common scenarios that decrease the performance of IRIS in most cases and offers an InterSystems-approved recommendation for consideration.  

Ten recommendations

We currently use a combination of Ghostscript and ImageMagick to accomplish our PDF requirements.  These products are ceating memory/cpu issues when merging large PDFS.  I am trying to find out if Intersystems Reports can handle our requirements (see below).

Hi Community,

This is a detailed, candid walkthrough of the IRIS AI Studio platform. I speak out loud on my thoughts while trying different examples, some of which fail to deliver expected results -  which I believe is a need for such a platform to explore different models, configurations and limitations. This will be helpful if you're interested in how to build 'Chat with PDF' or data recommendation systems using IRIS DB and LLM models.

I have a flask application, its working locally. I also have a iris for health 2024.3 docker container front-ended with the iris nginx container.

I can configure the WSGI application with iris for health, give it a "url" (/flask or /csp/flask) but I cannot access the flask application. It looks like the url is not found within the nginx configuration. Is there any documentation or suggestion for configuration/enabling a flask app with a IRIS container front ended with the nginx container (provided by intersystems container registry) 

February 19, 2025 – Alert: SQL Queries Returning Wrong Results

InterSystems has corrected two issues that can cause a small number of SQL queries to return incorrect results. In addition, InterSystems has corrected an inconsistency in date/time datatype handling that may lead to different, unexpected – yet correct – results for existing applications that rely on the earlier, inconsistent behavior.

DP-436825: SQL Queries with Lateral Join May Return Wrong Results

The first issue (DP-436825) only affects SQL queries that use a lateral join, either implicitly or explicitly, on an instance

Hi beloved members of the Community!

It is very common in the daily life of IRIS or Health Connect users that it is necessary to install new instances or update the ones they already have and in many cases it is not these same users who carry out the installation, but rather systems personnel who often do not take into account the particularities of the assignment of permissions necessary for the installation.

Hi,

I running an SQL so I can find the databases with the largest amount of free space. This is in case I can compact the databases.

However SQL cannot find the SYS.Database table.

Can someone please explain how to fix?

FHIR repositories, applications and servers typically serve clinical data in small quantities, whether to return data about a patient, their medications, vaccines, allergies, among other information. However, it is common for a large amount of data in FHIR/JSON format to be requested to be used to load into Data Lakes, identifying study cohorts, population health, or transferring data from one EHR to another. To meet these business scenarios that require large extractions and loads of data, it is recommended to use the FHIR Bulk Data Access feature provided by HL7 institution.

Hi all!Here I would like to share how we use vector search and GenAI with InterSystems technology.As an example, I'll describe BG-AppealAI project, which our company submitted to the InterSystems Vector Search, GenAI and ML Contest.BG-AppealAI application can write an appeal if you upload an insurance contract and the insurance company’s letter with a refusal to pay medical expenses.Of course, we are aware that at the moment AI has not reached such a level as to create ready-made legal documents.

Hi, this post was initially written for Caché. In June 2023, I finally updated it for IRIS. If you are revisiting the post since then, the only real change is substituting Caché for IRIS! I also updated the links for IRIS documentation and fixed a few typos and grammatical errors. Enjoy :)

In this post, I show strategies for backing up InterSystems IRIS using External Backup with examples of integrating with snapshot-based solutions. Most solutions I see today are deployed on Linux on VMware, so a lot of the post shows how solutions integrate VMware snapshot technology as examples.

Just curious what the process is for debugging either a .py file that is uploaded to a specific namespace/location or a python classmethod defined in a .cls file.

My method can be run via the "Debug" breadcrumb but it doesnt hit breakpoints it just runs without a debugger. Also objectscript methods debug correctly

Hey everyone.

I came across some issues when setting up Freeze and Thaw batch scripts for use with VMWare in a Windows ecosystem, and I wanted to share what I found in the hopes it can help others. This was undertaken in an environment using Healthconnect 2019.1.x.

IRIS not up (2)

It seems that the sample script from the documentation in my my case would tell me that the environment was not running (despite it running). To correct this, I provided the filepath to the Mgr location as so:

c:\InterSystems\HealthConnect\bin\irisdb -s"C:\InterSystems\HealthConnect\Mgr" -U%%SYS

Hi all,

I have a passthru REST setup using EnsLib.HTTP.GenericService and EnsLib.HTTP.GenericOperation. Works well.

I am adding some logic to the Operation and for some scenarios I want to return an HTTP 40x response status code.

I create an httpResponse object within the Business Operation, but I can't figure out how to set the http response status code that is returned to my Posstman client that initiated the request. I set StatusCode=400, and StatusLine and ReasonPhrase properties - but when the ultimate requestor (Postman) receives the response back it is a 200 status code.

Hey everyone.

As I have been working with IRIS (nee Caché) for some time now, I decided to take a look at how I manage things like functions and scripts that may not belong to a single namespace or environment, but should still have a home.

I have taken to creating a github repo where I can keep track of a single .cls of "general functions" that I can then drop into an environment when required.
