#InterSystems IRIS

Just wanted to share my Zabbix template for monitoring InterSystems IRIS on Linux servers.

It monitors irisusr (configurable) memory consumption:

• Virtual memory size
• Percentage of real memory
• Resident set size
• Size of data segment
• Size of code segment
• Peak resident set size
• Size of locked memory
• Size of shared libraries
• Peak virtual memory size
• Size of pinned pages
• Size of page table entries
• Size of process code + data + stack segments
• Size of stack segment
• Size of swap space used

How to use:

1. Check that you have Zabbix installed (I'm using version 4.2)
2. Import template file:
3. Add template to a server with InterSy

Is there a way to set null in dynamic object without using %Set methods?

I have this method and I need to set NULL as, well, null and not string.

ClassMethod node(name) [ CodeMode = expression ]
{
{
    "name":(name),
    "content":($case(##class(%Dictionary.ClassDefinition).%ExistsId(name), $$$YES:"mycontent", $$$NO:"NULL"))
}
}

Hi,

I want to do ordering dynamically in Query. I mean to say that order by value will not be hard coded in query, it will be passed in parameter.

I have tried to it following way, but it is not working for me. Can you please advise me how can I achieve it?

In below code, Order by :objSearch.SortingField is not working.

Class Query.ExternalUsers Extends %Library.RegisteredObject [ ClassType = "", DdlAllowed, Owner = {_SYSTEM}, Not ProcedureBlock ]

{



Query Search(objSearch As LISSystem.ModelView.UserSearch) As %SQLQuery [ SqlName = ExternalUsersSearch, SqlProc ]

We've just published an update to the Serenji extension for VS Code. Starting with this version (3.0.7) you can now debug the code that implements your REST services. Here's a taster:

How Are Containers Different From Virtual Machines?

Hi Developers!

Suppose I have a project where I want to build an IRIS container with two different dockerfiles depending on goals.  How can I make it?

The issue is that docker-compose is looking for the file with name 'dockerfile'

Are there any #IF constrations in a dockerfile syntax? 

Commenting works but sometimes it's more than one line.

This article introduces InterSystems iKnow Entity Browser, a web application which allows to visualize extracted and organized text data mined from a large number of texts, powered by InterSystems iKnow technology, which is also known as InterSystems Text Analytics in InterSystems IRIS. Feel free to play with the demo of this tool or learn more about it on InterSystems Open Exchange.

I started the development of this project in late 2016. From now on, my iKnow Entity Browser is used around the world by those who use InterSystems technology in their stack and those who do text mining. This

Hi,

I'm sure I'm not the only one who's already assembling matching pairs of socks for this year's Global Summit in Boston later this month .

Hello everyone,
After some work with IRIS we want to share our ToolBox-4-Iris with you.

What is this about?

The ToolBox-4-Iris is an API for IRIS with a collection of handy and useful tools - features that are not available in IRIS, but greatly simplify application development. To save time and effort on the "typical tools" that every developer needs. This includes additional classes, individual methods or even more efficient macros, which are described in the respective packages.

Macros
General ObjectScript macros, Status macros, National Language Support macros, and JavaScript macros.

I want to assign below query result into my Person class which have Name,DOB properties, and then  convert into JSON.

SELECT Name,DOB FROM Sample.Person

I got below error when passing Date in timestamp format.

I am using %JSON.Adaptor. Please refer screen 2

Some time ago, InterSystems introduced the concept of %DynamicObjects.
This feature is a powerful tool that makes it very easy to convert any string of JSON text to objects and vice versa.
However, in the work that J2 Interactive is doing for our customers, there are a couple of things that "need some tweaking".

Very often, we create REST services for our customers. Those services have a payload (in JSON format) that contains information that our customer expects in the form of an object that is proprietary to them.
We can easily convert that JSON stream to a %DynamicObject, but, if we try to pa

Hello everyone! 

Recently I search how to convert Cyrillic to Latin with Cache Object Script, but didn't find anything and decided to write ourselves, 

So here code:

    Set convertArray = $LB(
        $LB("а","a"),$LB("б","b"),$LB("в","v"),$LB("г","g"),$LB("д","d"),$LB("е","e"),$LB("ё","e"),$LB("ж","zh"),$LB("з","z"),
        $LB("и","i"),$LB("й","y"),$LB("к","k"),$LB("л","l"),$LB("м","m"),$LB("н","n"),$LB("о","o"),$LB("п","p"),

Hi Community!

Sometimes I meet a method which accepts 10+ parameters.

And often I need only the 8th parameter  to  pass. And I call the method something like:

do ##class(Some.Feature).Method(,,,,,,,"flag")

And I don't like this method when I call it like this cause, you know, often I just miss the number of commas and raise some other flag I wanted.

How do you avoid this situations? 

If you meet such a code, how do you call it and sure that you didn't miss the number of ","?

What is a good number of parameters in a method and f you need to pass more parameters in a method what do you do?

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.

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?

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

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 versio

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.
