You can change System Mode, you can put whatever you want to be displayed there

Will be displayed on top of the management portal, much more visible than the instance name

Can be set during startup by using iris merge

[Startup]
SystemMode=Demo System

It was developed ages ago. I did not do it for Windows, but I think it should be possible to make it working

Ages ago I've impleted project named BlocksExplorer, with a various of ways of using it

One of them is generating a picture of of the database, and visualization of defragmentation.

I think I tried it once on 2TB Database, but that was long time ago.

Anyway, this tool generates picture in BMP format, where each pixel represents each block in the database, so, for 

For 2TB database, it will be around 268435456 blocks, that will be a picture 16384x16384, and in BMP with a 3 bytes per pixel, it will be around 768MB for this picture, quite big one

This project is fully open, you can try to modify it a bit, and maybe if you do it per global, you will be able to make a map

There is one more way of getting it, is using ASQ

USER> write responseData.apply("$.items[0].titles[0].value.en_US").%Get(0)

did you try /usr/irissys/mgr/python, that's the path expected to be used by IRIS packages

pip install whatever --target /usr/irissys/mgr/python

and another place is /usr/irissys/lib/python, it's a place where InterSystems places Python Embedded support

sys.path, is a list of folders where python will look for the installed modules

Did you try using more appropriate package %Stream for it?

In your case, you would need to use %Stream.FileCharacter

 Set stream=##class(%Stream.FileCharacter).%New()
 $$$ThrowOnError(stream.LinkToFile("c:\export.csv"))
 set rs = ##class(%SQL.Statement).%ExecDirect(, "SELECT a, b FROM table")
 if rs.%SQLCODE'=0 {
     throw ##class(%Exception.SQL).CreateFromSQLCODE(rs.%SQLCODE, rs.%Message)
 }
 while rs.%Next() {
    set line = $listbuild(rs.a, rs.b)
    do f.WriteLine($listtostring(line, ","))
 }
 $$$ThrowOnError(stream.%Save())

Additionally, nowadays using embedded classes does not give much advantage, if it's not for one row result, only makes the code a bit harder to read

The codebase for AI, not enough in comparison to other languages. Even with much more popular languages, it makes mistakes, but yes, much less.

To help with it we need to significantly increase codebase in GitHub in ObjectScript, so that AI will have something to learn from.

When you start background job, in the master process, you can collect $zchild with a pid of started process

and collect them in the logs, and then in the loop you can check $data(^$job(child)) if it's still running

that's the simplest approach

Implemented for Interoperability: it can check status, including items in it, restart, update, recover, and check for queues and errors.
There is also SQL Query executon

Looks like there is no one specific use case for server, and there are so many variants on how it can be implemented

Do you have something in mind, how would you use it?

Just thinking about the list of tools to add in server implementation

The value should be static, at the time of creating record on table

For dates it uses range feature, so, you can split it by months, year (I suppose)

and move the whole bunch of records including indexes to another databse

Dmitry Maslennikov · Mar 16, 2025 go to post

While we moved our application to AWS, and we have some data, which we need to keep for a while. With this feature, we can move old data to a cheaper storage.

I believe the ability to move to a cheaper storage is mostly the case. Another option is that some table is too big, and someone would like to split it to be stored in multiple different databases, together with the indexes.

I think you just confusing $listbuild with list in BPL context. In BPL when you define it as List Collection, it will use class %Collection.ListOfDT, or in case of array it will be %Collection.ArrayOfDT

That means, that you should use 

 if 'context.Facilities.Find(##class(Ens.Rule.FunctionSet).SubString(context.EpicDepartmentID,1,4))
 {
   do context.Facilities.Insert(##class(Ens.Rule.FunctionSet).SubString(context.EpicDepartmentID,1,4))
 }

The support for NodeJS in IRIS is quite primitive and limited to only native functions, globals, methods, no SQL

check in IRIS folder, what do you have installed with IRIS for nodejs

I don't have windows, only docker, and in my case

/usr/irissys/bin/iris1200.node
/usr/irissys/bin/iris800.node
/usr/irissys/bin/iris1600.node
/usr/irissys/bin/iris1400.node
/usr/irissys/bin/iris1000.node
/usr/irissys/dev/nodejs/intersystems-iris-native/bin/lnxubuntuarm64/irisnative.node

If you want to use IRIS SQL from nodejs, you can try my package, which you can install with npm

npm install intersystems-iris
const { IRIS } = require("intersystems-iris");

async function main() {
    const db = new IRIS('localhost', 1972, 'USER', '_SYSTEM', 'SYS')
    console.log('connected')
    let res = await db.sql("select 1 one, 2 two")
    console.log(res.rows);
    await db.close()
}

main()

It's quite simple at the moment, only supports SQL with no parameters, but should work I believe

I'm not familiar with HL7 processing, but I suppose should be like this

foreach(<field>)
{
 set $list(list, * + 1) = <field>
}

if you need to create list, than $list on the left side, with  *+1 as position, to add to this list, and the right side, any value you would like to add to the list

Dmitry Maslennikov · Mar 4, 2025 go to post 
USER>kill list for i=1:1:10 { set $list(list, *+1) = i } zw list
list=$lb(1,2,3,4,5,6,7,8,9,10)

Is this what you're after?

Awesome, thanks for using sqlalchemy-iris

btw, in case when you run it inside IRIS, you can use python embedded mode, this way

engine = create_engine('iris+emb:///USER')

Studio is already deprecated and works only on Windows

Accessing the management portal depends on how you installed IRIS and which version you used. Your installation may not have private web server installed, and you would need to install any webserver yourself.

run command:

iris list

it will output something like this

Configuration 'IRIS'   (default)
    directory:    /usr/irissys
    versionid:    2025.1.0L.172.0com
    datadir:      /usr/irissys
    conf file:    iris.cpf  (WebServer port = 52773)
    status:       running, since Sat Feb 15 06:34:51 2025
    SuperServers: 1972
    state:        ok
    product:      InterSystems IRIS

Here is WebServer port is what are you looking for, and the full URL will be http://localhost:52773/csp/sys/UtilHome.csp

If you don't have a private web server, check documentation, on how to configure separate web server

Tried to check 2025.1, but did not find it

$ docker inspect --format '{{ index .Config.Labels "com.intersystems.platform-version" }}' containers.intersystems.com/intersystems/iris:latest-{em,cd,preview}
2024.1.3.456.0
2024.3.0.217.0
2024.1.3.456.0

For some reason, the preview points to em version, why so?

For the community edition,

$ docker inspect --format '{{ index .Config.Labels "com.intersystems.platform-version" }}' containers.intersystems.com/intersystems/iris-community:latest-{em,cd,preview}
2024.1.2.398.0com
2024.3.0.217.0com
2025.1.0.204.0com

At least here it is 2025.1 version

but, I've noticed that em version now not the same as for enterprise edition

Anyway, where is 2025.1 for the Enterprise version? The community edition is too limited to check everything on it.

The post is two months old at this point, but it's not available.
