Hey Developers,

We're pleased to invite you to join the next InterSystems IRIS 2020.1 Tech Talk: Using Java and .NETon June 16 at 10:00 AM EDT!

In this installment of InterSystems IRIS 2020.1 Tech Talks, we put the spotlight on extending InterSystems IRIS with your own custom Java and .NET code. We will demo how to create a custom interoperability component with the new Productions Extensions (PEX) feature. Following that, we’ll demo how to call Java or .NET code from any ObjectScript code.

Looking at the documentation, I see that the global ^ROUTINE brings the information and code of the .INT version of the routines. However, I would like to know where the equivalent information of the .MAC version is, as I did not find any reference to this in the documentation.

Some information in the .MAC version are hidden or already converted into the .INT version, and I would like to have access to this information through the system, and not just opening the routine in the studio.

How to start Using VsCode

Introduction

In the next few weeks, my coworkers are planning to start using VSCode to code with InterSystems' products. Among the many advantages of that, I would emphasize being able to connect with other technologies, such as GitHub, with ease. Besides, VSCode also offers an extensive extensions store, where you can find many free add-ons that make coding faster and more efficient. Last but not least, to conquer the heart of every developer, it is open source.

I am working on a TrakCare JIRA issue that requires accessing class properties in a different installation of TrakCare on another machine. For instance, I need to compare the deprecated items in the current version of TrakCare to the deprecated items in a previous release. Is there anything in the built in classes that will allow me to do this, or is it something I'll need to do with a SQL stored procedure or something else I haven't thought of?

I was able to define ECP connection in Installer class that I run when I build docker image for my Docker IRIS application. Now I start to use Amazon ECS and Autoscaling. When a new instance is created and it runs the IRIS container, I want it to "register" as an Application server on the remote database server. What code can I execute to add an ip address as an Application Server?

Hi

I'm using a class which extends %XML.Adaptor adaptor and I want to create an XML file with multiple namespaces, like the following:

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
</soap>

However, I don't see how to do this with the code I have. So far, I have

Hi community members!

Recently a customer ask me about a problem that detected when they were trying to send a post call to an external HTTP service, this service has changed and now it redirects to another URL, so they have setted to true the FollowRedirect parameter (setted to false for POST calls by default), what is the problem? They are sending a custom header in the post call and after the redirection this value is deleted.

While I can see the benefits that $ZSTORAGE could have if used properly, I have not seen it used in the environments I have worked in. I was wondering if there are any developers that promote its usage.

If used properly, I would imagine it could be highly effective in maximizing free memory since some processes will never go over X amount, while others may very well need much more.

Hi everyone,

I am still learning the platform for a student project and have to do some streaming and data analysis next. Since for my case I have no "live api" I wanted to just stream json files and output the data as it comes in from the files. (basically to emulate a incoming data scenario)

So thanks to the documentation and community posts I have figured how to create a stream and read data from a JSON but since I'm also new to JSON I have some parsing problems. I don't know how to access subarrays/sub-objects via objectscript.

Announcing gj :: locate. A simple extension for VS Code that will help you get to the source of your errors.

In VS Code, using either the Serenji extension or the basic InterSystems objectscript extension, this small add-on will open the appropriate class or routine and position you at the exact line where an error occurred.

No more tedious counting of lines to find <UNDEFINED>zCredit+206^Ledger.Invoice.1. Instead, with gj :: locate you can get there with just a couple of clicks.

This 20 second video tells it all:

JSON - NULL Properties

So I've been reviewing a lot of questions posted in the InterSystems community regarding NULL properties in JSON. I've also been reviewing the JSON documentation. None of these things have been able to help me so far.

1. We don't seem to have the %JSON.Adaptor class available for us to use in our system.

2. I'm not really confident enough to create JSON Type classes or backporting code, etc.

Is it a good practice to set the MAXLEN value of %Library.String property type? Will it lead to wasted storage if its not really using it?

For example, I have to store a 5 characters long string into the below str field. Which of the statement is recommended?

Property str As %String;

vs

Property str As %String(MAXLEN="5");

Hi:

I don't understand how to use this open exchange item for auto creating deleting items. I think it assumes knowledge in the steps of how to use it which i don't get.

Hi, community!

Consider you need to exclude substring(s) from a string.

I did it with the following snippet:

/// excludes all the substrings from the string
ClassMethod ExcludeSubstring(substr,str as %String) As %String

{

 while ($L(str,substr)>1) {

 set str=$Piece(str,substr)_$Piece(str,substr,2,*)

            }

 quit str

}

So, for example:
