On DR Async Member, I found that the addDatabase method cannot be used to add a non mirrored database to the mirror. Is there any other method?

Hi,

In Objectscript it apperas these characters have a special meaning:

^var <- Does the ^ mean the variable after it is a Global
set status=##class(%SYS.Journal.System).GetState() <- Does the ## mean anything?
Does the % mean anything?

Does the $ mean anything?

Managing InterSystems Servers – Virtual April 1-5, 2024

Now users can filter the CCR table by multiple conditions for the CCR tables displayed on the home page and the CCR tab of the System Details page.

Previously users were only able to filter the rows by one condition at a time. This made it cumbersome for users to quickly find CCRs that they knew met multiple conditions, as they would have to choose the condition that would produce the least number of results for them to then manually filter through.

I need to write test cases for Object script but need help for understanding the mock library in IRIS? Or need Suggestion for how to use mocking

Hello everyone,

I am looking for the syntax or the way to use a class created in the "BNA" Namespace (my application) from the %SYS Namespace.

Here is the context:

I have a "BNA" application contained in the "BNA" NS, this application provides a user creation functionality. This feature creates both the user in a table in the application and in the Iris system.

Hi Developers!

I want to share with you the approach you can use working with Unit Testing which I personally find very convenient and robust.

Will not talk much here about Unit Testing, we have documentation, enough good articles on the topic not only on the Internet but here on Developers Community too, e.g. this one.

How can you manage the Unit Testing of your ZPM module?

This is pretty handy with ZPM. It has a special command "test" which runs all the tests you mentioned in the module. You can execute it as shown below:

zpm:USER>module-name test

And this command runs all the tests you mentioned in module.xml.

Let's see how it works.

Online document says: TUNE TABLE updates the SQL table definition (and therefore requires privileges to alter the table definition). Commonly, TUNE TABLE also updates the corresponding persistent class definition. This allows the gathered statistics to be used by the query optimizer without requiring a class compilation.

Hey Community,

Hello everyone!
So, I am supposed to receive a REST-request into my production, and I need to send it, exactly as I received it, to another server.
I am struggling to find any good info on this, and have a hard time coming up with a good approach.
What would be the easiest way to do this?
- I have so far thought about possibly doing it with an EnsLib.REST.GenericService and then sending it with an EnsLib.REST.GenericOperation.

In the WRC, we often see customers contact us because they are having been provided a .PPK file for use with SFTP connections, but they don’t know how to use that key within InterSystems IRIS. This article will explain why this represents such a problem, and explain how to use the .PPK key to generate a Private / Public Key pair in a format recognized by InterSystems IRIS.

Work Queue Manager (WQM) is a feature of InterSystems IRIS that enables you to improve performance by distributing work to multiple concurrent processes programmatically. The idea is that you split the work into chunks, and WQM distributes the chunks across worker processes and can provide the info that the work is done.

However, recently, I got an interesting question: there's a large logical transaction composed of ~1,000,000 individual objects and SQL inserts and updates. Some updates are CPU-intensive, so the original idea was to use WQM to split an update into chunks to speed things up.

But, here's a catch: if one of the individual 1,000,000 changes fails (there's a variety of application-level checks so that it can fail, and that's not even that abnormal a behavior), the entire transaction must be rolled back. That creates a problem: each chunk must report success before committing their individual transactions, and someone must get all these reports and decide if we are committing or not.

Unfortunately, it looks like WQM does not have a bidirectional communication between workers and manager, so I suggested an approach using events:

1. Start jobs.
2. Wait for all jobs to report success using $System.Event.WaitMsg().
3. Send Commit or Rollback using the $System.Event.Signal().
