InterSystems IRIS 2024 recently introduced the vector types. This addition empowers developers to work with vector search, enabling efficient similarity searches, clustering, and a range of other applications. In this article, we will delve into the intricacies of vector types, explore their applications, and provide practical examples to guide your implementation.

At its essence, a vector type is a structured collection of numerical values arranged in a predefined order. These values serve to represent different attributes, features, or characteristics of an object.

Hello my friends,

I have a problem with logi report, 

in my store procedure,  I create code like this?

$ListToString(%DLIST(DISTINCT (ARCIM_Desc)),'<br/>') as "ARCIM_Desc", -> this is the problem

$ListToString(%DLIST(DISTINCT (MRDIA_ICDCode_DR)),'<br/>') as "MRDIA_ICDCode_DR", -> it's works fine

as you see there's a <br/> in the display of the report

I have no idea about this, maybe someone can help me fix this problem ?

Thank You

Best Regards,

I recently started trying out Python in IRIS, but now I get this message repeated over and over again:

^Sources is not setup so hooks will not work

No idea where this came from and how it started. Any suggestions?

Hello my friends,

I have a problem with Objectscript, why the value of address become like this ?

everything works fine except the Address,

this is my code, do I need something to make this into real address ? should I put something in my code ?

            if '$isobject(paper) continue

            set Address=paper.PAPERStName

thank you for your help

Hello my friends,

I have a bit problem with date format, I need to display like this DD-MM-YYYY

I've put the objectscript like this : set DOB=$zd(paper.PAPERDob,15)  

and the result is 

Why It cannot show the full year, I mean why 99 or 95 why not 1999 or 1995 ? 

Thank You

Best Regards,

Hi,

If I test the Native api for Node.js from the documentation, I noticed (if I'm correct) all methods and calls are synchronous. By default due to the nature of Node.js, there is only one thread of execution and normally  all JavaScript methods and all calls should be asynchronous and use either a callback function (the "old way") or promises or the async/await contruct to return their result, e.g.:

• myFunction(params, callbackFunction(response))
• myFunction(params).then(resolveFunction(response))
• async someFunction() {
  ​​​​​  response = await myFunction(params)
  }

Hello and welcome to the Developer Ecosystem News!

The second quarter of the year was full of exciting activities in the InterSystems Developer Ecosystem. In case you missed something, we've prepared a selection of the hottest news and topics for you to catch up on!

I like Application Error Log a lot, both for its full stack and a big list of variables. I'd like to "hack" this functionality and record the same in this log when a certain variable has a certain value. This quasi error should not be visible to the user, and it should not interrupt the application flow. Is that possible?

Throwing an error in a try-catch block does not record the error, tested. I am considering recording variables and the stack differently, I know how to do both, but that would miss the nice Application Error Log functionality.

Is there a way to change the background color of webterminal at the server side?

Maybe some *.class or *.css file on the Iris server?

I would like to have different colours on differents environments (test,pre,pro)

Thanks

Hello community,
Is there any built in class method to get the HTTP request and response message format from the %request and %response object. Similar to how a Web Gateway's HTTP Trace Facility captures HTTP messages.

Thanks!

I'm trying to gather more data for one of my namespaces so I can do some analysis. However when I run .BuildIndex() nothing populates in the resulting SQL table. I've tried deleting the class and reimporting and compiling and still nothing. I feel like I'm doing something OBVIOUS that's wrong but I can't quite figure out what it is. Here's what I'm doing (Customer name redacted)

I am receiving a FHIR response bundle back with a resource of patient. Using fromDao, I attempted to take the stream and put it into FHIRModel.R4.Patient but it is not mapping correctly. When I attempt to take FHIRModel.R4.Patient and write it out using toString(), all I am seeing is the resource

{"resourceType":"Patient"}

so the response is not mapping correctly to FHIRModel.R4.Patient. How have others handled this? Do I need to translate it to an SDA since it does fit the model format?

Hi,

In the business rule I want to send a message to the business operation if any of OBX:8 (Abnormal Flag) is set.

I am trying to get the value of a Submit button on a CSP object page.

<input type="Submit" value="Assign" name="action" id="action">

I tried getting it thru $GET(%Request.Data("action")), but it throws an Undefined error. Isnt $GET supposed to handle it if its undefined anyway?

How do I get the "value" of the button pushed when the form is set to POST?

Hi everyone,

I’ve set up a scheduled task in InterSystems IRIS to run every night at 2:00 AM, but it doesn’t seem to trigger consistently. Some nights it works as expected, but other times it just skips without any error in the logs.

The task is marked as enabled, and there are no conflicts in the Task Manager. I’ve double-checked the system time and time zone settings all looks fine.

Could it be a cache issue or something to do with system load?

Thanks!

When accessing management portal through IIS the page is not fully rendered and the buttons/links that are displayed don't work.

Management Portal works fine through private web-server.

Have just set up IIS/CSP Gateway to access Ensemble, and accessing the CSP Gateway configuration pages through IIS works fine (screenshot at end of post).

This is the view when accessing management portal through IIS (port 80) - missing images, links don't work, not all content displayed:

And this is the (top of the) view when accessing through the PWS (port 57772):

Do not let the title of this article confuse you; we are not planning to take the InterSystems staff out to a fine Italian restaurant. Instead, this article will cover the principles of working with date and time data types in IRIS. When we use these data types, we should be aware of three different conversion issues:

1. Converting between internal and ODBC formats.
2. Converting between local time, UTC, and Posix time.
3. Converting to and from various date display formats.

You've probably encountered the terms Data Lake, Data Warehouse, and Data Fabric everywhere over the last 10-15 years. Everything can be solved with one of these three things, or a combination of them ( here and here are a couple of articles from our official website in case you have any doubts about what each of these terms means). If we had to summarize the purpose of all these terms visually, we could say that they all try to solve situations like this:

In IRIS, every time a request need to be processed, a specific IRIS process (IRISDB.EXE) need to be assigned to handle that request.

If there is no spare IRIS process at that time, process will need to be created (and later destroyed). On some Windows systems (especially with security/antimalware solutions being active) creating new processes can be slow, which can results in delays during peak times (due to inrush of requests).

I like the Application Error Log functionality a lot. However, it becomes time consuming to inspect it date by date and directory by directory on a multidirectory server. Ideally, I would use an existing error class to write a custom error report by date, selected namespaces, etc. Does such a system class actually exist? Not that I found. The detail level on the screenshot below is enough.  
Some Application Error Logs go back a couple of years and load for a long while. Is there any programmatic way to clean them? Deleting errors in GUI date by date and directory by directory is rather
