I have created a New Database/Namespace within our TEST environment on both the Primary and Backup of the mirror. When I go to create the database/namespace on the DR node I am getting "Cannot open file '/ensemble/TEST/iris.cpf_...." while the cpf file that it references does not exist. Anyone have any clue to why this might be happening?
Why I've decided to write this
In my last article I've talked about returning values with Python. But returning them is simple, what can make it harder is what I'm going to talk about today: where the value is treated.
Python object in IRIS
Following the example of the last aricle, we have the method:
Class python.returnTest [ Abstract ]
{
ClassMethod returnSomething(pValue... As%String) As%Integer [ Language = python ]
{
return pValue
}
}
Then, we'll have as a return a Python object, that IRIS interprets as the class %SYS.
Hi,
Can anyone please tell me how to append a string using a update query.
For eg : "Hello" is the string . I need to append the string world and it needs to be "Hello world".
Thanks

During the realization of some required functionality, I discovered that I need to use Deflate compression, and found, that IRIS does not offer any options, $system.Util.Compress, works one way open (GZIP/COMPRESS) totally different, even for the same algorithms, I see that what I would expect as a result for Deflate somewhere there, but Compress returns something more. Is there any way to get a correct result using just ObjectScript without a need to use external tools? Was it really so difficult to have Deflate implemented in the first place?
Hi,
We're getting a string sent to us by a client that was compressed using a java deflater (the zlib algorithm) and when trying to use $System.Util.Decompress() I get an "illegal value" error. I gather from other community posts that this is because the raw compressed string is missing the customized wrapper Iris automatically adds. I know this has been a longstanding issue for a while...just wanted to check if there'd been any updates to this functionality, or successful workarounds for decompressing raw zlib compressed data. Thanks in advance!

Hi,
While HL7 Errors ACKs come back in the soap response, the HL7v2 Error ACK message is not processed.
I used the SOAP Wizard to construct my classes, but the generated code doesn't handle the HL7v2 ACK.
Does health Connect have a class that handles this?
Failing an official solution should I go ahead and make make my own classes based on EnsLib.HL7.Operation.TCPOperation, but wrapping it with the generated SOAP handling code.
How have others dealt with this?
e.g.<?xml version="1.0" ?>
<!-- type: LNW.WebService.PKB.Response.
Hi all.
I'm currently looking at a use case where I need to take a Stream, and then encode the contents as a Base64 Stream. This is currently achieved with a snippet of code that has previously been placed in multiple classes within this particular environment, and relied on the dotnet gateway (which suffers with a bug in 2022.1, corrected 2022.1.1).
Therefore I will be replacing the dotnet implementation with the standard $System.Encryption.
good afternoon!
I was trying to set up the "File Spec" to match the exact filename that will be in the file path.
however, it seemed grab whatever the name of the file and work on it.
wondering how I can specific the exact filename in "File Spec" so that It wont touch other files in the same path?

Digital health solution providers face increasing pressure to integrate complex health data systems while ensuring scalability, security, and compliance with standards like HL7 FHIR. Fast Healthcare Interoperability Resources (FHIR) has revolutionized health data exchange by offering a standardized framework that allows diverse health IT systems to communicate effortlessly. But simply adhering to FHIR standards isn’t enough to overcome the intricacies of health data integration. Solution partners must leverage advanced architectural components like FHIR brokers, façades, and repositories to build scalable and efficient solutions. InterSystems offers all the essential features you need to implement FHIR for your health data, whether on-premises, in a public cloud, or as a cloud-based service managed by InterSystems.

Hey Community,
It's time for the new batch of #KeyQuestions from the previous month.

Hi Community,
Are you READY to test your InterSystems technology skills?

I'm not so experienced in administering IRIS but as far as I understand IRIS for Health community comes with a web server out-of-the-box while licensed editions require Web Gateway to be deployed.
I was able to install dockerized instances of IRIS for Health 2025.1 along with Web Gateway, double checked that _SYSTEM and CSPSystem users are not locked, changed passwords for both, configured the gateway to connect to IRIS, then created a web gateway app (/iris) and checked the connection is OK. Now I'm struggling with accessing Management Portal.
We have an OAuth server configured as an identity provider, and we have an external application (from another provider) that connects correctly with OAuth.
I have a Task that I am trying to write the output to a file. How do I check for if the Output File has been included in the Task Schedule, so I can direct my output of my class to that output file?
Thanks

Hi Guys,
How can I create Python pages instead of CSP or Zen pages, not familiar with Python and the only way I know is using embedded Python as methods as attached below?

Thanks
Let's suppose two different routines use one and the same chunk of code. From the object-oriented POV, a good decision is to have this chunk of code in a separate class and have both routines call it. However, whenever you call code outside of the routine as opposed to calling code in the same routine, some execution speed is lost. For reports churning through millions of transactions this lost speed might be noticeable. Any advice how to optimize specifically speed?
P.S. Whenever someone is talking about the best choice for whatever, I am always tempted to ask: "What are we optimizing?".
Hi All,
I am trying to build a very basic data transformation to convert messages from OML^O21 to ORM^O01. However, I'm unable to loop through multiple ORC segments.When I use the source document type 2.5: OML_O21, I am not able to loop through multiple lines of the ORC segment.Interestingly, if I use the source document type 2.3: ORM_O01, I am able to loop through multiple ORC segments successfully.I am currently using the following data transformation logic:

How would you go about creating an SQL Stored Procedure that would result in the same output as "IN LIKE"?
For example...
CustomersTable
| RecordId | CustomerName |
| 123 | Mark Stevens |
| 456 | Betty Johnson |
| 789 | John Stevens |
| 321 | Brian Smith |
| 654 | John Markson |
| 987 | Tom Obrian |
select *
from CustomersTable
where inLike('%Mark%', '%John%')Would return:
| 123 | Mark Stevens |
| 456 | Betty Johnson |
| 789 | John Stevens |
| 654 | John Markson |
Hi everyone,
I’m new to this community and could really use some help with creating a production in InterSystems IRIS for Health Community 2024.3. I have deployed my instance using Docker.
Here’s what I’m trying to do:
- Input: I have an HL7 file that is processed by the standard
EnsLib.HL7.Service.FileService. - DTL Transformation: I’ve created a DTL to transform the HL7 content into a custom class like this:
Class Demo.MyApp.Messages.JSONEvent5 Extends (%Persistent, %JSON.Hi Developers!
As you know the concept of ObjectScript Package Manager consists of ZPM client - client application for IRIS which helps you to install packages from the registry. And the code which works "on the other side" is ZPM Registry - server which hosts packages and exposes API to submit, list and install it. Now when you install the ZPM client it installs packages from community package registry, which si hosted on pm.community.intersystems.com
But what if you want your own registry? E.g. you produce different software packages for your clients and you want to distribute it via private registry? Also, you may want to use your own registry to deploy solutions with different combinations of packages.
Is it possible? The answer is YES! You can have it if you deploy ZPM registry on your server with InterSystems IRIS.
To make it happen you would need to set up your own registry server.
How to do that?
Hi IRIS experts!
I have a parameter in a class that stores a global name:
Parameter GlobalName = "^AGlobal";
then I'm trying to call it as:
set gn=$name(..#GlobalName)
to use it later as:
set @gn@("index")="value"
But! I'm having syntax at set gn=$name(..#GlobalName)
What am I doing wrong?
