#InterSystems IRIS

When deploying IRIS in a container, what are recommendations for permitting users terminal access? There is docker exec -it, but that does not work from a user's workstation where - in the old deployment model - they would connect to the server over ssh using Putty and open a terminal session from there.

How InterSystems solutions handle C10k connections? ( https://en.wikipedia.org/wiki/C10k_problem )
For example, I want to create a social network on InterSystems platform.
In the scenario client (browser) => CSP Gateway => Cache can the Cache handle a large number of clients at the same time?
Quick analysis shows that CSP Gateway for each request opens a new TCP connection to Cache SuperServer (port 1972) allocating CSP session and license slot.

We have a function that was written for us that allows us to create text files for logging certain aspects to the OS using %Stream.FileCharacter. We had no issues with this until we moved from AIX to Red Hat.

Now it seems the 1st time the function is called, and the file is created the permissions seem to be correct on the file. But as soon as we attempt to write another line to the file using MoveToEnd() it seems the permissions are changed on the file. I have been able to narrow the issue down to the MoveToEnd() by calling the function from different users.

I've installed the latest version of IRIS using Minimal settings as I'm just looking for some basic IDE without connecting to anything.

After install, I see all the files in the Intersystems folder, however there is no "IR" in the system tray. I don't see any executables to launch either. System restart did not populate the system tray either.

Is there any other way to launch Studio?

Hi.

After upgrading to IRIS 2023.2 documentation link doesn't work.

Any suggestions?

I have the variable with literal.

Can I understand with ObjectScript that the literal is:

%String,

or %Integer,

or %Date,

or %Double,

or %Numeric?

What I'm looking for could be:

set variable="To be or not to be"

USER>w ##class(utils).GetType(variable) 

%String

set variable=42

USER>w ##class(utils).GetType(variable) 

%Integer

Hi folks!

When I launch IRIS as a docker container instance, e.g. like this one:

docker run --name iris-sql -d --publish 9091:1972 --publish 9092:52773 intersystemsdc/iris-community

And then try to connect to it e.g. via irissqlcli it says I need to change the password:

Hi,

I don't like the default terminal very much because it can't change the window size freely.

How to use CMD or PowerShell?

Hello!

I wonder if anyone has a smart idea to extract an XML fragment inside a text document (incoming from a stream)?

The XML fragment is surrounded by plain text.

Example:

text...........
text...........
<?xml version="1.0" encoding="UTF-8 ?>
<Start>
...etc
</Start>
text...........
text...........

The XML is not represented by any class or object in the Namespace.

The XML can look different from time to time

Hi All,

I would like to install Intersystems IRIS studio, So I went this link

https://login.intersystems.com/login/SSO.UI.Login.cls?referrer=https%253...

But I am getting the below error.

So what will be the next step for me!!! please guide me........

Hi folks!

Consider I have a class "X.Y.Z"

What is the SQL table name for it? How can I obtain it via ObjectScript?

A quick search doesn't show any methods and properties. Documentation is a bit "wrong" here saying that the SQL table name is the same. It will be at least 'x_y.z'.

Any help is very appreciated!)

I am doing a HL7 data transformation with object script but need to only write a substring from the first "(" of the NTE-3 field to the end.

example

Input: NTE|1|||Some text (HI) (321)|ABC

Desired Output: NTE|1|||(HI) (321)|ABC

Basically I'd like to delete "Some text ".

If I were writing a shell script I would use sed 's/^.*(/(/' with perhaps a modification to get only the first.

I use the function wizard but can't seem to get the right code.

Hello Community,

I hope you are well.
I encounter a problem on IRIS for Unix 2020.1 when I try to create a PDF from a simple Dashboard on Deepsee :

When I click on this widget , a tab appear and is loading for ~30 seconds, then shows 'error loading the PDF File ' :

When I run my IRIS in a Docker Container I know the host an know the mapped ports
so access is no problem.

BUT: is it possible from my IRIS
- inside a Container
- 'inside' Docker
to find the actual IP address of the Host?

This may sound strange, but for error tracking, it could be quite important.
