Question Alexei Yugov · Nov 15, 2024

Hello. On some hosts, IRIS in containers.intersystems.com/intersystems/iris-community:2024.1 falls with a core dump.

auser:~$ docker run --rm -it --entrypoint=""

Coredump stack:

(gdb) bt
#0

Are there some hardware requirements for IRIS docker container? Or maybe some specific settings?

Hello Community,

I'm starting to explore OAuth2 and, as a first step, I want to set up an OAuth2 authentication with Microsoft. I've created a small sample page that attempts to sign in with Microsoft. However, after entering the user credentials, the redirection doesn't work.

Greetings dear community members!

I have recently been deploying an IRIS for Health image on a Docker with a preconfigured Webgateway image and I have come across the problem of the SSL configurations that allow us to connect to the IRIS instance using HTTPS and going through our Webgateway.

Until now I had always deployed IRIS for Health with a Community license, which still has the Private Web Server installed, so I only needed to configure the Webgateway connection with the deployed IRIS instance:

Question Dmitrij Vladimirov · Nov 22, 2024

Hence the question: is there a way to do that?
The goal is to get data (from half a thousand to 3-4 thousands lines) from DB, calculate standart deviation  then use it as logical condition in analyzer. 
For example IF std > custom_value = show_the_result ELSE null
There is a STDDEV(MDX) method used in Analyzer but it is a measure and it can not be used as logical condition (correct me if i am wrong)

And there is a Embedded Python with numpy, but logic behind STDDEV(MDX) and numpy.

Question Pietro Di Leo · Nov 20, 2024

Hi everybody, 

I'm modifying a REST interface for a client but it seems impossible to me to modify HTTP Response Status and including custom HTTP Headers either.

My dispatch class (extending %CSP.REST) is contacted through a POST request and the latter is processed in a custom class (extending %CSP.REST as well) accessed as shown in the example below:

  <Route Url="/test" Method="POST" Call="Custom.Test:Process" />

Within the processing class I tried executing the following statements with no success:

Do%response.SetHeader"totalcount"

As we keep updating our software, we often realize that we require more and more modern solutions. So far, only one major piece of our software relies on reading barcodes in documents and images. Since Cache did not have a means of reading barcodes in the past, we have always achieved our goals by using a Visual Basic 6 application. However, it is no longer an ideal solution because it is currently complicated to maintain it. IRIS also lacks this capability, but it has recently got an option that makes up for it: embedded Python!

Question Davi Massaru Teixeira Muta · Nov 21, 2024

Is it possible to check retroactive LOCK history?
 

context:

I found it in the application error log. Some LOCK errors - ERROR #5803
Is it possible to somehow identify the point in the job or process code that caused these locks?

At the moment I no longer have table LOCKS on the server, but I would like, if possible, to check the time at which the incidents occurred.

Question Alexander Rischke · Nov 22, 2024

Good morning dear community,

This is like my first post in this community. Let's see how this turns out.
I have a question about the Intersystems Kubernetes Operator and the deployment of the webgateways.
I am responsible for the hosting and deployment of the apps. For the future we are planning to host our application in a kubernetes cluster. I am using the IKO for this.
I am using webgateways, for external access as separate pods. And sidecar containers for internal access, like the management portal.

My current Problem is the configuration of the webgateways.

Question Norman W. Freeman · Nov 15, 2024

I use the following code to calculate the SHA1 of a file :

set##class%Stream.FileBinary

This code is called thousands of time and performance is critical. I have tried to code same logic in another language (which is lower level) and it's almost twice as fast. It's unclear why so I started investigating.

Using Process Monitor, it shows that files are read in chunks of 1024 bytes (1K) which is suboptimal. Reading a file of 1MB while require 1024 file system calls. Usually bigger buffer is used (eg : 4096 or 81920).

The SHA1HashStream() function is implemented this way : 

160

stream.

Hi Guys,

I'm a newbie in Dockers & containers and trying to install IRIS & VS Code in a container with dockers in Linux.

My understanding is that I first need to install docker, create a container then install IRIS image and looked into this documentation (Container How-to | InterSystems IRIS Data Platform 2024.2) and got me lost so I guess I need baby steps:

So I've installed Ubuntu in my Desktop and went to https://containers.intersystems.

Question Scott Roth · Nov 20, 2024

I am using a JDBC connection to MS SQL server to execute a stored procedure to select data and bring it into InterSystems as a EnsLib.SQL.Snapshot. I loop through the EnsLib.SQL.Snapshot using a while loop, but I also want to iterate through the Columns within that Row to do logic.

Is there a way to iterate through the Columns of the current Row of the EnsLib.SQL.Snapshot so I can apply logic/rules for further processing?

Thanks

Scott

Hello,

While doing research on the upgrade to InterSystems IRIS 2024.1.2 version, I was wondering if it would be possible to rollback the installation and return to the previous version in case something went wrong ?

I didn't see anything talking about this in the documentation and when I tried to re-install an older kit over an upgraded instance, I couldn't use it.

Thank you in advance for your reponse

Speeding Up Antibiotic Resistance Detection with InterSystems IRIS

Antibiotic resistance is a critical health challenge, requiring rapid detection to inform effective treatments. We worked on developing a solution that leverages InterSystems IRIS vector database technology that would quickly identify resistance genes in DNA.

How It Works

Using vector embeddings, DNA sequences are transformed into numerical representations that capture essential genetic information. InterSystems IRIS then enables high-speed searching and matching of these vectors, identifying possible resistance genes.

Hello all,

We have our system with AutoParallel enabled:

USER>w ##class(%SYSTEM.SQL.Util).GetOption("AutoParallel")
1

But whenever I try to run any sql the autoparallel does not work. For example, this simple query:

When I force it with %PARALLEL we can see it will effectively run in parallel:

The total records is bigger than the threshold. So, what can go wrong? Anyone in the same situation?

Question john.smith4237 · Nov 17, 2024

Hi Guys,

We are planning to move our system from windows to Linux and I never used Linux before and all I know that is another operating system, so the new server has Linux which looks like just terminal session like Dos and as I ran "uname -r" command to check for the version in it shows some like "6.1.112-124.190.amzn2023.x86_64".

So for the available IRIS distribution and can only found versions for Ubuntu and Red Heat, so do I have to either install one of them to be able to install & run IRIS?

How to create an ODBC connection on your native Windows laptop to IRIS running on a Windows VM on the same computer, test the connection, and pull data from IRIS into Excel.

Recently I learned that Excel can connect to external databases via ODBC. This includes basically any ODBC data source. Since IRIS speaks ODBC via the ODBC API, we can take advantage of the InterSystems ODBC Driver to establish an ODBC connection to IRIS on Windows that Excel can utilize.

Question Csaba Gyenge · Nov 15, 2024

Is there a way to create and establish DICOM Association with Extended Negotiation? 

I have implemented DICOM Query/Retrieve C-FIND, using EnsLib.DICOM.Operation.TCP and EnsLib.DICOM.Process base classes. My application, acting as an SCU, needs to query by Study Date-Time (combined date-time matching) range with timezone query adjustment. For this, I need to use Extended Negotiation.

I've checked the IRIS Manual - Creating DICOM Associations section but there is no mention of this.

Discussion Joel Solon · Nov 11, 2024

The IRIS Installation Guide for Linux, Installation Directory section, says "Do not choose the /home directory, any of its subdirectories, or the /usr/local/etc/irissys directory." but there are no suggestions or any default.

What are your opinions on this? For example, I see that IRIS in a Docker container is installed in /usr/irissys. I'm wondering why that directory was chosen.

The official Linux filesystem docs say:

  • /usr is the second major section of the filesystem. /usr is shareable, read-only data.

InterSystems FAQ rubric

By default, the order of columns in a table is determined automatically by the system. To change the order, explicitly set the order for each property using the property keyword SqlColumnNumber when defining the class.

Example:

Property Name As %String [SqlColumnNumber = 2];

Please see the documentation below.

SqlColumnNumber

If you want to change the SQL table name, specify SqlTableName. If you want to change the column name (field name), specify SqlFieldName.

Both apply only to persistent classes.

I just restarted an AWS instance that have been dormant for 6 months (license still valid) only to find that the web application on there doesn't work and that I cannot connect to the management portal. I can however connect to the web gateway fine but it reports the "Server is currently unavailable". 

Grateful any for any advice.

Question omer · Oct 1, 2024

Hello everyone, 
so lets say i have the following:

Hello
Q
say(arg)
    w arg
 Q


and i am trying to execute it by its name such as:


s a = "say^hello"

*execute the name inside a*
 

now I know for a fact that if say were written without any argument then do @a would work!

but I can I pass an argument in this case?
I don't want to use Xecute because I am in need of really high performance code.

I'm having an issue with sending SMTP requests from a specific Microsoft 365 account to Gmail accounts. We can use other Microsoft 365 accounts, but something about this one specific account sending to Gmail fails. The error we get is just telling us that sending to the user xxxxx@gmail.com failed. In order to troubleshoot that, I'm looking for more detail than that.

I see %Net.SMTP objects have a Debug property, but when I set it to 1, I can't see anything happening differently. What does that debug value do?

I assume IPM manifest tag UnitTest is tightly coupled with the standard unit test framework, right? However we have our own one that predates the standard one and we are not going to switch.

I think I need to import the unit test cases and then be able to run a single class method for the test run. Any ideas how this would be possible?
