InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

This package offers a utility to export an XLarge Global into a JSON object file and to show
or import it again. In a previous example, this all was processed in memory. But if this is a
large Global you may either experience <MAXSTRING> or an <STORE> error
if the generated JSON structure exceeds available memory.
 


Academic refers to the structure created.

Question Michael Davidovich · May 18, 2022

Continuing on the journey of implementing %UnitTest, @Timothy Leavitt's Test Coverage package, and automated testing with Jenkins.

My question today: why do we utilize a unit test root directory?  

I've been defining packages and classes to write unit tests as I've been developing and I run the tests on the command line or using a routine file that is setup as a debug target which has been working great.  I use DebugRunTestCase() to do this (so the classes aren't deleted).

Hi

I have a few Zen pages, one of which is implementation of  %CSP.StreamServer which I'm using to download a PDF file, however, any file downloaded is 5Kb smaller than the original. This is the code I'm using:

Class GMECC.DocmanConnect.Pages.downloadGPNotOnHub Extends (%ZEN.Component.page, %CSP.StreamServer)
{
    ClassMethod GetId()
    {
        Quit $Get(%request.Data("filepath",1))
    }

    ClassMethod OnPreHTTP() As %Boolean
    {
        set filepath = %request.Get("filepath")
        
        set tFs=##class(%Stream.FileCharacter).%New()
        set tFs.

I ran into an interesting ObjectScript use case today with a general solution that I wanted to share.

Use case:

I have a JSON array (specifically, in my case, an array of issues from Jira) that I want to aggregate over a few fields - say, category, priority, and issue type. I then want to flatten the aggregates into a simple list with the total for each of the groups.

The InterSystems Iris Fhirserver running on a Raspberry Pi Raspberry running as a FHIRserver

Raspberry running as FHIRserver

About a year ago I wrote some articles about the installation of the HAPI FHIRserver on a Raspberry Pi. At that time, I only knew the basics of the FHIR standard, little about the technology behind FHIR-servers and not much more about the Raspberry. By trying, failing, giving up and trying again I learned a lot.

An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once. For example, the word anagram itself can be rearranged into nag a ram, also the word binary into brainy and the word adobe into abode. Wikipedia

You will receive two strings returning true if the two arguments given are anagrams of each other. As usual shortest solution wins.

Question Michael Davidovich · May 13, 2022

We are experience this with our own web app and even the demo/template here: intersystems-community/iris-fullstack-template: This template shows you how to build, test and deploy a simple full-stack application using InterSystems IRIS REST API (github.com)

When changes are made to CSS or HTML files, we can see the changes are saved to file in the Docker container by visiting the command line.  However, after refreshing, clearing cache, etc. the changes don't appear on the web application in the browser.  Viewing the source css in the browser, we see it's the old file.

Format Change in the ^mtemp and ^ERRORS Globals

InterSystems has several routines, methods and utilities that can create stack dumps.  Stack dumps are created in the ^mtemp(index) global by the %SYS.ProcessQuery:ExamStackByPid(.) classmethod as well as by some undocumented legacy entry points of the ^%STACK utility.  Stack dumps can also be created in the ^ERRORS(date,index) global by the ^%ETN trap routine, including additional entry points BACK^%ETN, LOG^%ETN, ^%ET and the Log() method of exception objects.

Question Ivan Wang · May 10, 2022

From  IRIS log, I found lots of following content

05/05/22-01:05:11:375 (16166) 0 [Generic.Event] ECP: Mirror Connection request from 'SM25SDLMIIRROR:LOCALHOST.LOCALDOMAIN:IRIS' (10.xxx.xxx.27:33040)

05/05/22-01:05:11:376 (16166) 1 [Generic.Event] ECP: Active server not defined, cannot redirect mirror connection

Could any one explain a little bit for me?

This is a benchmark built in python and objectscript in InterSystems IRIS.

The objective is to compare the speed for sending back and forth a thousand request/message from a BP to a BO in python and in objectscript.

See https://github.com/LucasEnard/benchmark-python-objectscript for more information.

IMPORTANT : Here are the results of time in seconds, for sending 1000 messages back and forth from a bp to a bo using python, graph objectscript and objectscript.

String messages are composed of ten string variables.

Hi folks!

Sometimes we need to import data into InterSystems IRIS from CSV. It can be done e.g. via csvgen tool that generates a class and imports all the data into it.

But what if you already have your own class and want to import data from CSV into your existing table?

There are numerous ways to do that but you can use csvgen (or csvgen-ui) again! I prepared and and example and happy to share. Here we go!

Question Daniel Bertozzi · Apr 13, 2022

Recently our team have been getting requests to pickup a large amount of data from API nightly (e.g. using ODATA to loop through pages) and placing that into MS SQL databases.

My question is, what is considered the best practice to get data from API and route to external SQL database WITHOUT persisting any messages/traces etc?

At the moment my thinking would be to write a service that triggers an action once a day to an EnsLib.HTTP.OutboundAdapter, then map the HTTP response into a linked table (via method to keep the operation clean that managed the gateway on the way in and out of the method).

Discussion David Underhill · May 5, 2022

I am sure I came across this in the past with Cache and just saw this again in IRIS.

When rebuilding or swapping a DAT file for a database it retains the Resource of the DAT file, not the Resource of the Database it is being used for.

For instance, if I have a local Database called APP with a resource %DB_APP and I want to refresh the data from another Database called TEST that has a Resource %DB_TEST I can just copy the DAT file from the TEST folder to the APP folder.

No Database settings are changed and it is all done with either IRIS down or the databases dismounted.
