#InterSystems IRIS

I have the following servers in IRIS mirror set:
Arbiter; isc_agent only
LIVETC01; IRIS DB full install; Primary
LIVETC02; IRIS DB full install; Backup

A couple of days ago IRIS hung.
The application using LIVETC01 DB stopped functioning.

I'm trying to find out the sequence of events leading up to the failure.

I see these entries in the log:
Arbiter:
2023-01-17T15:54:56 ISCAgent: Arbiter client error: Message read failed.

I have a production with one Business Host - a Business Service which I need to scale automatically to consume ~80% of CPU time.
Business Service pulls data from a (non-FIFO) queue so that I can adjust pool size without any issues.

So far, I'm planning a different BS running every X seconds and sampling CPU with $system.Process.GetCPUTime() and scaling the pool size of the main BS up/down based on that metric.

Has anyone tried something similar? Any advice/code samples would be appreciated.

Applications that work with bill payments and receipts, as well as the delivery and inventory of items, generally require the use of barcodes or QR Codes. The latter is used in even broader scenarios since the QR Code can store more information than a simple bar code. Thus, it is important to have the ability to generate barcodes and QR Codes or read the data stored in them from an image or a PDF. This article will show you how to do this using Python and some of its free libraries.

Pyzbar library

The pyzbar library reads one-dimensional barcodes and QR codes from Python 2 and 3 using the zb

I have noticed that the way the nodes are ordered is different between 2 different environments.

If I create the following global :

set^TEMP("Z")=1set^TEMP("Ä")=1

Then I dump it with zwrite, I get this (which is expected):

^TEMP("Z")=1^TEMP("Ä")=1

However, on another machine, it gives me this :

^TEMP("Ä")=1^TEMP("Z")=1

The same goes for the following command (which return 0 or 1, depending environment) : 

write"Z"]]"Ä"

Both are running Windows 10, but one is running IRIS 2021.1, the other CACHE 2017.2.2.

I don't think that's the reason, maybe there's something else (a config

HI ! I'm working on a caché upgrade to IRIS.

in some abstration cls classes, to get a property was used $METHOD(..Obj, propertyName_"Get").
On Caché 2018,  had as a return property value, if the property does not exists, an exception of type <PROPERTY DOES NOT EXIST> throwed

Now, on IRIS 2022.1,  will always be throwed an exception of type "<METHOD DOES NOT EXIST>".

I can change  $METHOD  to  $PROPERTY, but as it is an abstract class, I cannot guarantee the type of the referenced Object, if the property is encapsulated or private, I need call $METHOD(..Obj, propertyName_"Get").

Messages are received via HTTPS protocol by webgateway containers. 

Interoperability production runs in compute pods with persistent data, journals, and WIJ volumes.

Hi All,

I want to move into CACHE/IRIS DBA role. Can anyone suggest what all learning must be done in order to move in this role. 

It would be great if you can provide the learning path as well for the topics. (links from I can learn the provided topics)

Thanks in advance!!

We're having a problem with the way Python modules are being cached in Iris. If we modify some code and then reimport a module it is still processing the old code.

I have created Tier 1 CCR and when I move it to Live it shows the below error.

I initially had changes deployed through a different CCR to the TEST environment and were not deployed to LIVE for the same class.

Hi Interoperability experts!

I'm into interoperability now with data transformations and I wonder: how can I use DTLs?

I've created one that transform Ens.Request into Ens.Response. How can I use it now in the production?

I'm trying to add the business process expecting to see it available in the list but it seems it is not the case. 

Tried documentation and it doesn't say either what to do after creation the DTL.  If it is obvious could you please help?

Why I decided to write this

Recently I had the challenge to create a secure authentication method to authorize access to some data, but unfortunately I had zero experience with those security configurations and I felt that I was missing some basic concepts to have a better understanding of the official documentation.

After studying and managing to deliver the classes that I was asked to develop, I'd like to share a little bit of my new knowledge, which helped me follow the topics in the documentation.

Hi Developers!

"objectscript.conn" :{
      "ns": "IRISAPP",
      "active": true,
      "docker-compose": {
        "service": "iris",
        "internalPort": 52773
      }

I want to share with you a nice new feature I came across in a new 0.8 release of VSCode ObjectScript plugin by @Dmitry Maslennikov and CaretDev.

The release comes with a new configuration setting "docker-compose" which solves the issue with ports you need to set up to make your VSCode Editor connect to IRIS. It was not very convenient if you had more than one docker container with IRIS running on the same machine. Now, this is solved!

Read below how it works now.

In Interoperability productions Inbound Adapters extract and separate retrieval logic from actual payload processing, which is left to a BS.

At a high level, an adapter looks like this:

Class MyAdapter Extends Ens.InboundAdapter {

Method OnTask() As%Status
{
  Set request = ..RetrieveRequest()
  Set sc = ..BusinessHost.ProcessInput(request)
  Set..BusinessHost.%WaitForNextCallInterval=1
  Quit sc

}
}

However, in many cases, RetrieveRequest retrieves a batch payload, so our adapter looks like this instead:

Class MyAdapter Extends Ens.InboundAdapter {


Method OnTask() A

Hi guys,

Suppose I have a JSON string as below:
