#InterSystems IRIS

Can you please provide steps to debug in VS code using serenji and how to put break point in VS code, I have tried using F9 but it is not working.

I want to debug API code using postman.

Hello, I have a task created in my task manager, calling my Business Service class, and it's working fine.
But I need to know the ID of the task, I searched within the class  %SYS.Task.Definition and found nothing related.

Class Example.Tasks Extends %SYS.Task.Definition{Property BusinessService As %String [ InitialExpression = "Example" ];Method OnTask() As %Status{

Our team is reworking an application to use REST services that use the same database as our current ZEN application. One of the new REST endpoints uses a query that ran very slowly when first implemented. After some analysis, we found that an index on one of the fields in the table greatly improved performance (a query that took 35 seconds was now taking a fraction of a second).

We saw this improvement on our development system and our test system. However, when we moved the code to the production system, the query still took “forever”. What went wrong?

• We checked that the code was properly

Hi Developers!

InterSystems IRIS stores everything in globals and if we use ObjectScript classes to persist data class documents globals it uses in storage. But if you use globals for calculations, temporary storages, for special indexes or for some other purposes - how do you document it?

Possible options which come to my mind:

1. Macro

#define Array ^MyGlobal

usage:

s $$$Array(1)=1

2. Class parameter

Parameter Array ="^MyGlobal";

Usage:

s @(..#Array)@(1)=1

3. Documentation comment

Just document it to have it in a class documentation

/// ^MyGlobal is used to store my data

What do you do?

Object Synchronization is a feature that has been around for a while, since Caché days, but I wanted to explore a bit more how it works. I've always thought that database automatic synchronization is complex by nature but, for some particular scenarios shouldn't be so hard. So I considered a very simple use case (OK, perhaps the typical one, I'm not discovering anything... but if it's common and it works, it's good ). You can download from GitHub and compile it into your system, generate sample data and play a bit with it. It's done for InterSystems IRIS but it also should work in last

Hi all,

One of the most useful features for me in IRIS was the queue page. From there, I could see how the different elements (BS, BP & BO) from a production were behaving, thanks to the possibility of auto-refresh every second. Great thing.

But we have updated to 2019.1 and this possibility is gone... we need to refresh manually! So, is there any way to set a parameter somewhere to have the queues status refreshed automatically?

Thanks a lot.

 I have two local instances:

• IRIS for Windows (x86-64) 2018.1.2 (Build 626_3U) Wed Jun 12 2019 19:07:59 EDT
• IRIS for Windows (x86-64) 2019.1 (Build 510U) Thu Mar 14 2019 14:13:37 EDT

I'm using Java Gateway to talk to external system.

Both instances are using the same:

• jar
• generated class
• java version

They are calling the same method with this java signature:

package isc.rabbitmq;
public class API {
    public void sendMessage(byte[] msg) throws Exception {}
}

On the InterSystems IRIS side I'm calling it like this:

set sc = ##class(%Net.Remote.Service).OpenGateway(gatewayName, .gatewayConfig)
set sc

Hi! I am creating a Jasper Report using IRIS like DB, I've created my Data Adapter to connect with my DB configuring the JDBC connector and it works perfectly:

But when I try to create a report connecting to my DB I am getting this error:

InterSystems API Manager Introduction

Hello everyone,

I was first introduced to TDD almost 9 year ago, and I immediately fell in love with it. 
Nowadays it's become very popular but, unfortunately, I see that many companies don't use it. Moreover, many developers don't even know what it is exactly or how to use it, mainly beginners.

Overview

My goal with this article is to show how to use TDD with %UnitTest. I will show my workflow and explain how to use cosFaker, one of my first projects, which I created using Caché and recently uploaded to OpenExchange.

So buckle up and let's go.

What is TDD?

Hello gentlemen,

here is my question: I would like to delete files one by one (not all at a time because I need to check somethinkg to delete it or not) in a defined folder but how can I handle it?  I have used the extension :

EnsLib.File.PassthroughService

But it only works when a file is moved in my folder... But I want to launch my program everyday (with a planifier) in the purpose to delete file that more that 2 months old. With "PassthroughService", it won't work since the the file is not moved so it won't go in my onProcessInput...
If you can offer me a solution, I'll take it :)
Here is a

Hi all, I have released the latest version of VSCode extension for ObjectScript already a month ago, and finally a time for the info about this new release.

So, what's new in the release:

What's new in this version

• added export setting "objectscript.export.addCategory" if enabled uses the previous behaviour, adds category folder to export folder, disabled by default
• added Server actions menu, by clicking on server info from status bar. Open Management portal, Class Reference and toggle connection.
• Class Suggestion in ##class, Extends, As, CompileAfter, DependsOn, PropertyClass
• $SYSTEM suggestion by Classes from %SYSTEM
• Import and compile folder or file by context menu in File Explorer
• Server Explorer, now possible to open any other namespace
• Macros suggestion

For details how it works now, look further.

Hi,

I have a method that has multiple parameters and is normally used from other classes in ObjectScript. Most of the parameters have default values. Withing the server code that's perfect. In some areas I can call myMethod(,,"sometext") or myMethod(tVariab) and thats fine... I use it as it's required in each place.

But now I want to expose it as a REST service so I need to buld a kind of wrapper., another method in a REST dispatcher class that will receive the parameters in a JSON object and will call the server method already implemented. Something like:

{"par1":1111, "par2":"sample text",

IRIS provides us with anti login CSRF attack mitigation, however this is not the same as a CSRF attack, as login attacks only occur on the login form. There are currently no built-in tools to mitigate CSRF attacks on api calls and other forms, so this is a step in mitigating these attacks.

See the following link from OWASP for the definition of a CSRF attack:

https://www.owasp.org/index.php/Cross-Site_Request_Forgery_(CSRF)

The method shown in this article for mitigating these attacks is currently not proactive, but a minimum that needs to be combined with other attack vector prevention methods,

Hi developers!

Every day coding with IRIS and docker I call the following 3 commands in VSCode terminal. Always the same for any projects:

docker-compose build   ; to build the container

docker-compose up -d   ; to run the IRIS in container

docker-compose exec iris iris session iris ; to open the IRIS terminal

Is there any way to map the key sequence which will type me the rest? 

e.g.

irisb for docker-compose build,

irisup for docker-compose up -d,

irist for docker-compose exec iris iris session iris

I know and use keyboard sequences for mac, but it doesn't work in VSCode terminal :/

In many projects I was faced with storing hierarchical data (tree) in classes.
By tree, I mean such data, where each node has a parent node — an object of the same class.
Many examples of such data can be given. For example, a catalog in the online store. Suppose that this online store sells books, in this case, the category tree might look like this:

The number in front of the name is the category ID.
For storage, you can create classes:

The MyApp.Category class  is used to store the category tree and contains the property “Parent” - reference to the same class.

But it’s not convenient to work

Hello Everyone

I'm trying to open an XML that I get inside a GZIP file.
However, I can only open the contents when I save the file to a folder.
I would like to know if there is a way to get the contents of XML without saving the GZIP in a folder.

The code below is functional, however, you are saving GZIP before you can get the contents of the XML.

SET tGZIP = $System.Encryption.Base64Decode("############")
SET tFile= ##class(%File).%New("####")
SET tSC = tFile.Open("WSN")
SET tSC = tFile.Write(tGZIP)
DO tFile.%Save()
DO tFile.Close()
SET tSC = tFile.Open("RUK:::/GZIP=1:/NOXY=1")

I'm not saying that this is in anyway "best practices," but I'm in a peculiar situation where I need to restrict users from starting a "retired" Ensemble Production in a namespace that's been renamed. It's still an "Ensemble-activated" namespace; we need to keep it available for Ensemble Message Viewer access ... fortunately, only for a little while.

It's a bit of a hack ...

Open the Production class in Studio and add the following classmethod:

ClassMethod OnStart() As %Status
{
    Return $system.Status.Error(5001,"THIS PRODUCTION IS DISABLED.")
}

A Production won't start if its OnStart()

Hello community! I have to work with queries using all kinds of methods like embedded sql and class queries. But my favorite is dynamic sql, simply because of how easy it is to manipulate them at runtime. The downside to writing a lot of these is the maintenance of the code and interacting with the output in a meaningful way. In an effort to have as much dynamism as possible so that we're not rewriting code constantly, and so that we have as little code possible (while still making sense and getting the job done), I made a function that takes in any dynamic query and outputs a dynamic object.
