Hi,

I use ZLANGC00 and ZLANGC01 for shortcuts at programmer level to some frequently used dev tools. Is there a way to pass 2 arguments to a command?

Example:

ZZQD "Queue1" // Equivalent to D ZZQD^%ZZLANGC00("Queue1") to display messages in queue1 (ZZQD is my own code in %ZZLANGC00)

but if I wanted to type ZZQD "Queue1" $H-3 to call ZZQD^%ZLANGC00("Queue1",$H-3) can it be done or do I need to write something to manipulate the argument? So ZZQD "Queue1-3"

I'm using the EnumerateJobStatus query of class Ens.Util.Statistics to obtain the LastActivity value of a Business Host.

I would expect that this would return the timestamp of the last message received by the BH, understanding that any connect/disconnect activity would reset that timer. However, the time returned appears to actually be the time at which Ens.MonitorService generated the alert and is not directly related to anything that happened in the BH itself.

Hello, I need to determine the best way to split a class containing multiple methods(about 20), into multiple classes in which each method is in its own class. I am wondering if there is another way other than manually creating the different classes, and copying each method into each class. Doing this in Intersystems Studio.

LS,

I'm trying to learn how to use the IKO for deploying solutions to Kubernetes. In my current project I'm trying to deploy the IAM onto a K8S context. Are there directly usable samples of the yaml file I need to use for that?

In Windows, set the processes with the following image names as monitoring targets.

[irisdb.exe]

contains important system processes.
* Please refer to the attachment for how to check important system processes that should be monitored.

[IRISservice.exe]

This is the process for handling IRIS instances via services.
When this process ends, it does not directly affect the IRIS instance itself, but stopping IRIS (stopping the service) is no longer possible.

[ctelnetd.exe]

%Service_Telnet Starts when the service is enabled and becomes a daemon process to access IRIS via Telnet.

Has anyone seen this before? I'm new/bad at Docker and not even sure how to debug.

I'm trying to update the hosts file on Windows in C:\Windows\System32\drivers\etc

I know that in Linux if you update the hosts file, you sometimes need to restart the Network Manager for the changes to take effect.

So my question is that is there a similar thing that we need to do on Windows or do the changes take effect as soon as the file is saved?

This is a  rather personal view of the history before Caché.
It is in no sense meant to compete with the excellent books from Mike Kadow discussed in an earlier article.
We have different histories and so this is meant to create a different perspective of the past.

The whole story started in 1966 at MGH (Mass.General Hospital) on a PDP-7 Ser.#103
with 8K of memory (18-bit words) [ today = 18K byte ]  as a spare system.

"Serial Number 103 - was located in the basement of the now demolished Thayer Building,
currently [2014] the site of the Cox Cancer Center at MGH.

I have a client who' recently acquired a business that was running software that uses InterSystems IRIS as the database back end.  In the process of preparing to have my company's software installed the client formatted the hard drive of his server, wiping out his data.  I can't convert the data to MS SQL without a functioning database.  He had a backup on an external drive, which I have copied down to my local machine.  I loaded up  a virtual machine with Windows 10 Pro, I installed Docker and IRIS.  I started searching for explicit instructions for restoring the .

Migrating data to another system takes two steps.

1. Migrating class definitions

To migrate the class definition to another system, export it to a file in XML format or UDL format (extension .cls).

The export procedure in Studio is as follows.

Tools > Export

> Select multiple classes you want to migrate with the [Add] button

> Check [Export to local file]

> Confirm that the file type is XML, enter a file name, and click [OK].

After this, import the exported XML and UDL files in the studio on another system. The import procedure in Studio is as follows.

Our team has had success creating and publishing Power BI reports using an ODBC connection to an IRIS database, but there have been concerns about the responsiveness of these reports.

As an attempt to improve responsiveness, I'm trying out the "DirectQuery" connection using the InterSystems IRIS connector available in our version of Power BI Desktop (September 2021). 

The version of IRIS I'm connecting with is "IRIS for Windows (x86-64) 2022.

Hi Community!

I think everyone keeps the source code of the project in the repository nowadays: Github, GitLab, bitbucket, etc. Same for InterSystems IRIS projects  check any on Open Exchange.

What do we do every time when start or continue working with a certain repository with InterSystems Data Platform?

We need a local InterSystems IRIS machine, have the environment for the project set up and the source code imported.

So every developer performs the following:

1. Check out the code from repo
2. Install/Run local IRIS installation
3. Create a new namespace/database for a project
4. Import the code into this new namespace
5. Setup all the rest environment
6. Start/continue coding the project 

If you dockerize your repository this steps line could be shortened to this 3 steps:

1. Check out the code from repo
2. Run docker-compose build 
3. Start/continue coding the project 

Profit - no any hands-on for 3-4-5 steps which could take minutes and bring head ache sometime.

You can dockerize (almost) any your InterSystems repo with a few following steps. Let’s go!

Is it possible to stop and start a production from the command line?

If so please tell me the command and hopefully a link to the documentation for such a function.

I understand that you can have only one production per namespace; namespace has to be enabled for production.

Thanks

Let's say you have Python including variable-length arguments methods. How can you call it from ObjectScript? 

deftest1(*args)returntest2

You can call this "a.py" from ObjectScript as below.  For **kwargs argument, create Dynamic Object in ObjectScript and put it into methods with <variablename>... (3 dots) format. 

Do you like playing ChatGPT? With this way, you can call ChatGPT APIs not only from Language=python method but from ObjectScript world.  As described in OpenAI page , ChatCompletion.create method of OpenAI library has **kwargs argument.

InterSystems has corrected a defect that can cause corruption of databases and journal files on AIX systems with IBM POWER8 or later POWER processors. This defect can be triggered only when database or journal encryption is in use.

Hi *.*,

I am new to IRIS, IKO and IAM. I have read through a lot of the documentation, but I need clarity on some things that I can't find in the documentation.

• Which Load Balancer does IKO use on the ingress?
  Can it be set to use another one? e.g. nginx-kubernetes + GCP LoadBalancer?
• On a multi-compute and multi-data instances deployment, how do you get to the Management Portal of each instance?
  i.e. The load balancer is the only point of entry into the cluster exposing 1972 and 52773, so how do I route to the individual instances?

Hi developers!

Want to share with you an exercise I tried with InterSystems IRIS Interoperability.

The sample shows how to use IRIS Interoperability with data transformation component to change the data in CSV file.

The story is below.

Hi Developers!

There is a recent update came for developer community images of InterSystems IRIS and IRIS For Health.

This release comes with Environment variables support.

Currently 3 variables are supported:

• IRIS_USERNAME=user to create
• IRIS_PASSWORD=with password
• IRIS_NAMESPACE=create namespace if doesn't exist

Here is what you can do - see below.

Start iris with your username and password created:

docker run --rm --name iris-sql -d -p 9091:1972 -p 9092:52773  -e IRIS_PASSWORD=demo -e IRIS_USERNAME=demo intersystemsdc/iris-community

Deltanji 7.1 is now available.

Key updates include: 

* Interoperability Production component driver included, for customers who have purchased the add-on. You can watch a short demo of it here.
* Implement multi-select delete of objects and components
* Add setting to give a passable Beyond Compare launch command line
* Support simplified Locations & Routes diagram 

For more information, read the release notes here >> https://bit.ly/3mHyJHc

Please get in touch with support@georgejames.com for your release kit. 

The update is also available for Serenji debugger users on VS Code, which has the Deltanji solo edition embedded. Simply update the Serenji extension to version 3.2.3 or later and load the server-side code. 

Git stores complete history - meaning you would never lose your files, even if they are deleted, they are still available. That, however, presents an issue if large or sensitive files have been committed. Deleting them DOES NOT remove them from history. Recently one of the repos I work on became unexpectedly large, so here's how you can resolve that:

Hi Devs!

For me, one of the most painful things about ObjectScript is ##class(Class).Method() typing to call a class method in code or in a terminal. I even submitted an idea to simplify it in ObjectScript.

But! There is a new feature in VSCode ObjectScript that was just introduced to the plugin - Copy Invocation!

Just hover Copy Invocation linkabove every classmethod in a code, click on it and the invocation is copied to the buffer:

Paste it anywhere you want it to execute!

USER>w##class

Bazinga!

Here is the video that shows how it works.

Many thanks to the VSCode contributors

Hi Developers!

As you know InterSystems IRIS Interoperability solutions contain different elements of the solution, such as: production, business rule, business process, data transformation, record mapper. And sometimes we can create and modify these elements with UI tools.  And of course we need a handy and robust way to source-control the changes made with UI tools.

For a long time this was a manual (export class, element, global, etc) or cumbersome settings procedure, so the saved time with source-control UI automation was competing with lost time to setup and maintain the settings.

Now the problem doesn't exist any more. With two approaches: package first development and usage of IPM package git-source-control by @Timothy Leavitt

The details are below!

A common need for our customers is to configure both HealthShare HealthConnect and IRIS in high availability mode.

It's common for other integration engines on the market to be advertised as having "high availability" configurations, but that's not really true. In general, these solutions work with external databases and therefore, if these are not configured in high availability, when a database crash occurs or the connection to it is lost, the entire integration tool it becomes unusable.

I have a %GlobalBinaryStream object that I'm trying to save as a local file after being received through a SOAP Web Service.

To do this, I created a %Stream.FileBinary object and wanted to set where the stream copied to this object would be saved by using either the DefaultStreamDir() ClassMethod or the NewFileName() ClassMethod. However, the documentation isn't very helpful on how to use these ClassMethods.

Right now, I have the below code:

set localStream = ##class(%Stream.FileBinary).%New()
set st = localStream.CopyFromAndSave(file) /// file is the %GlobalBinaryStreamObject
$$$QuitOnError(st)
set localStream = localStream.NewFileName(ext=<extension>,directory="path\to\folder\")
