InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

Hi,

I have two namespaces

  1. In the first one, I have defined a class which Extends (%Persistent, Ens.Util.MessageBodyMethods), we'll call it NSOne.Msg.Req
  2. In the second namespace NSTwo, I want to use the previous class with something like SET pInput = ##class(NSOne.Msg.Req).%New()

I mapped the NSOne.Msg.Req package in namespace NSOne. In Atelier, I can see NSOne.Msg.Req in my NSOne. But, when I try to execute line 2 above, it tells me :

Hi,

I like to validate some use cases and have the following question. I am relatively new to IRIS. Perhaps someone can help:

1. I have a global m[x,y,z,f] distributed across multiple sharded instances
2. I know that i can set assign computed SQL expressions to class variables using Objectscript
3. Is there a possibility in Globals API to do the same ? Set f = x + y as a computed expression in the global m[x,y,z,f] ?

a. We would want to use the global API to change f programmatically using code

Hi community,

I need to write an SQL query to fetch a random record from a table, that table has millions of data.

In postgresql, for example, there is a RANDOM() function to do something like that:

SELECT column FROM table
ORDER BY RANDOM()
LIMIT 1

Is it possible to do something like that in Caché?

Thanks in advance

I have a class:

Class test.Person Extends (%Persistent, %XML.Adaptor)
{
Property Name;
}

I want to serialize it into this XML:

<Person>
    <Id>1</Id>
    <Name>Ed</Name>
</Person>

Is it possible?

It's for the Visual Trace so I can't use %XML.Writer.

Hi everyone,

I'm trying to build my project on a Linux machine using Docker.

In my development environment, I use Windows 10 Pro with Docker Desktop version 2.3.0.5. Everything works fine, and the docker-compose build runs flawlessly.

But, when I tried to run the same project in a Linux.
Ubuntu 18.04.5 LTS (GNU/Linux 5.4.0-1025-azure x86_64), docker --version
Docker version 19.03.6, build 369ce74a3c

Question
· May 16, 2021
IRIS or Cache?

Hello all,

I am in a bit of a situation where I could get your help please.

I want to get certified with IRIS, but I also do see that there is an availability named Cache.

Are they both the same or different? if different please explain it to me as how?

Also what is the difference between IRIS, IRIS for Health, Deep Sea? Please explain to me.

Also what do you think I should get my self certified with?

Please leave your comments below.

Cheers.

Hello,

I'm quite new at InterSystems. I have a business process that's pointing two different business operations, but one of them I don't want it to point to.

I went through the FileSystem settings, data transformations, classes, and code to see what it could be, but I don't see why its connecting to this second operation.

What other inner-system mechanics would I need to consider? What have might I have missed?

Hi Community...I am trying figure this out any help appreciated. Thanks in advance

The service is a file passthrough that picks up a PDF and then uses the BPL code below to create the rest wrapper and sends the stream data. I am not grabbing the stream from the inbound correctly, "request.Stream" or "request.StreamFC" always produces the following error.

Here is what is sent and returned in the message..

request:

<Stream>

15@%Library.FileCharacterStream

</Stream>

I'm close with this but I'm not sure how to grab JUST the GT1.3 data. I know I can do a substring but finding the 3rd | is a tad tricky. I've not been this deep in SQL for 15 years.

SELECT SUBSTRING(hm.RawContent, (CHARINDEX('GT1',hm.RawContent)), 50) as NameDesc
FROM Ens.MessageHeader as em, EnsLib_HL7.Message as hm
where em.Status = 'Suspended'
and em.MessageBodyId = hm.id

I expect it should flow like this...

SELECT UNIQUE SUBSTRING(RawContent, (FIND 3RD PIPE),(FIND 4TH PIPE) as NameDesc ....

I have a BPL Business process which always processes messages - mainly it waits for responses since downstream systems are seriously async.

I need to update this process.

Wwould the existing instances of this Business Process complete correctly after the update?

My BPL changes would result in:

  1. New S method in the Thread class
  2. New OnResponse method in the context class

Both changes are in the middle of the process, so there are S/OnResponse methods before and after my change.

I have a workstation with a CACHE instance up and running.

On that same workstation there is also an instance of IRIS (fresh install). I would like to migrate manually the CACHE database to IRIS (ideally, all globals, routines and classes).

What I tried is to copy C:\InterSystems\Cache\mgr\CACHE.DAT to C:\InterSystems\IRIS\mgr\IRIS.DAT (after shutting down both instances) but it does not work.

I got the following message : (112) The service for the IRIS instance did not start.

I am currently running a docker image with Iris 2021.1 and I would like to install node js on to it. I have had a look at the instructions on the intersystems online learning portal and I must say its very confusing. Some of the documentation says that you can only install it on 2019. Other parts say that it doesn't matter and you can install it if you have a dev directory. I checked my dev directory and there it isn't there. Sadly this is very inconsistent. Does anyone know if it is possible to install on the above mentioned version of Iris ?
