Hey Developers!

Do you want to reap the benefits of the advances in the fields of artificial intelligence and machine learning? With InterSystems IRIS and the Machine Learning (ML) Toolkit it’s easier than ever.

Join InterSystems Sales Engineers, @Sergey.Lukyanchikovand @Eduard Lebedyuk, for the Machine Learning Toolkit for InterSystems IRIS webinar on Tuesday, April 23rd at 11 a.m. EDT to find out how InterSystems IRIS can be used as both a standalone development platform and an orchestration tool for predictive modelling that helps stitch together Python and other external tools.

Hi,

I have a global that holds users name and date of birth.

I would like to loop through them and check if the date of birth is more than 2 years based on todays date

so I have ^checker("under2", "Eric David", "02-05-2018")

I want to check the birthdate based on todays date to see if it is greater than 2. How do I access the birthdate in the global

Please can you advice

I tried :

set values = $order(^checker("under2"))
set td = $zdate($horolog, 3)
set ol = $p(^checker("under2"), ",", 3) // this does not work
while (values ' = "")
{
set difdays = $system.SQL.

Hi guys!

Portrait of  Madame X, Gustave Caillebotte.

One of the features I like in InterSystems ObjectScript is how you can process array transformations in a specific method or a function.

Usually when we say "process an array" we assume a very straightforward algorithm which loops through an array and does something with its entries upon a certain rule.

The trick is how you transfer an array to work with into a function. 

One of the nice approaches on how to pass the information about an array is using $Name and Indirection operator. 

Below you can find a very simple example which illustrates the thing.

We use a lot of external MS SQL calls to look up numerous things when it comes to HL7. I am running into an issue where the outbound calls are queued but the message is sent onto the next process before it gets a response. How do I get it to wait till the response gets back from the MS SQL call before sending it onto the next process?

Below is a screen shot of what I am trying to explain...Select Research Study executes at 8:33 the message is sent to the next process at 8:34, but the response of the MSSQL call doesn't come till 9:31.

Hello gentlemen,

I have to create a objectscript program that will simulate a mainframe (because it's going to be removed). For my program, I receive data from another program that is written in Delphy by TCP on a preset socket.  Here is my problem, how can I handle this? 
Which class shoud my program  extend?
Which Adapter should I use?
My program must be able to read what the delphy one is sending and i don't really know what structure it is in what it is in. So is there a class that can allow me to read it? Thanks for your future anwers.
Here is a sample of what I have thought but doesn't work.

Continuing on from my last post, I am posting my succesful output for the Day 2 Part 1 below.

A full explanation of Day 2 part 1 can be found at: https://adventofcode.com/2018/day/2 and the input can be found

A brief description of this exercise is that you receive a sequence of strings.

You have to count the if any duplicate or triplicate chars exist in the string.  Multiples will exist, but if you find multiple ldupicates / triplicates you will count them once.

At the end of sequence of strings you have to SUM the no.

I have a query that I would like to  have refreshing at certain intervals lets say every 30 seconds with out refreshing the page content using the META TAGS

refreshes the whole page but I have a jquery function that will run at those intervals that I can use the problem is getting the jquery to call my COS function or is the way to do it with pure COS

<html>
<head>
<!--meta http-equiv="refresh" content="30"-->

Hi all,

I'm facing the error 7802 ("Worker job/s unexpectedly shut down") when trying to work with the Queue Manager. Since today it was working fine, but suddenly today it started failing when arriving to the line:

Set sc=queue.WaitForComplete()

The method is pretty simple: first I invoke the queue manager by doing  set queue=$SYSTEM.WorkMgr.Initialize("/multicompile=1",.tSc,64), and then into a loop I call a method exactly 64 times. Then after the first 64 processes are done, the system launches 64 more jobs.

After many sleepless nights it's a pleasure to announce the newer, better, moderner ObjectScript compiler which implemented pretty much everything you ever wanted to have in modern ObjectScript:

• Design objective of this new compiler is to parse reasonable subset of current ObjectScript syntax which will look readable for stranger, and not scare them with 1 letter syntax. The good start for compiler was the old-good COS Guidelines from here https://github.com/intersystems-ru/cos-guidelines
• For reasons we mentioned above we do not parse 1 letter syntax. It's declared evil;
• We do not handle dotted syntax for the same reason - modern syntax with {} is proper replacement for dotted syntax blocks;

But we not only parse the modern ObjectScript syntax, we have implemented finally the long-standing request which we always dreamed about. Closures!

I have a wdsl soap request that now requires a header. Where do I modify the header to allow this new value to be sent?

   <soapenv:Header>
    <Headers xmlns="urn:epic-com.2013.Interconnect.Headers"> 
      <Epic-Client-ID>12349fe5-2ff8-4b79-b723-e69efbabcdef</Epic-Client-ID>
    </Headers>
   </soapenv:Header>

Thanks

Scott

I am trying to base64 encode a string with non standard characters encoded in utf-8 also tried windows 1252  and I am getting error like so 

ERROR <Ens>ErrException: <ILLEGAL VALUE>zEncodeStream+18^ -- logged as '-' number - @' set encString = $TRANSLATE($SYSTEM.Encryption.Base64Encode(streamString),$C(10,13))' 

any help appreciated if anyone has faced this before

I use Documatic a lot to generate class documentation from comments embedded in the code. Is there a good way to create documentation for SQL views as well? Ideally I want to document each column in the view with HTML markup similar to how I document each method of a class with Documatic.

How Tax Service, OpenStreetMap, and InterSystems IRIS
could help developers get clean addresses

Pieter Brueghel the Younger, Paying the Tax (The Tax Collector), 1640

In my previous article, we just skimmed the surface of objects. Let's continue our reconnaissance. Today's topic is a tough one. It's not quite BIG DATA, but it's still the data not easy to work with: we're talking about fairly large amounts of data. It won't all fit into RAM at once, and some of it won't even fit on the drive (not due to lack of space, but because there's a lot of junk). The name of our subject is FIAS DB: the Federal Information Address System database - the databases of addresses in Russia. The archive is 5.5 GB. And it's a compressed XML file. After extraction, it will be a full 53 GB (set aside 110 GB for extraction). And when you start to parse and convert it, that 110 GB won't be enough. There won't be enough RAM either.

I am having an intermittent issue that when I make a call to MSSQL from a BPL that the response does not come back in the amount of time required. Since the call from the BPL is synchronous I tried changing the timeout to 60 but it has not helped (see below). Is there anyway to guarantee that the call waits long enough for a response before continuing on?

Thanks

Hi Community!

We are pleased to invite you to the upcoming webinar "Machine Learning Toolkit (Python, ObjectScript, Interoperability, Analytics) for InterSystems IRIS" on 26th of March at 10:00 (Moscow time)!

Is it possible to mimic what selenium does like navigating to a site and logging in  and filling out a form then logout in COS.I am trying to do that in COS using %Net.HttpRequest class or should I be using a different class the idea is to be able to call a web app login into it and fill out form and log out

In recent discussion on CachéQuality I was (friendly) blamed for old syntax promotion and deliberate obfuscation of the code. Therefore I decided to clarify my point and shed some light on one of possible source of side effects that may unexpectedly occur with RETURN command with an argument.

what is the bullet point char value in COS the equivalent of •

Hi all,

Lets imagine that there's a process that locks an entry of a gived domain, in my example the ID 2 of the table User.tApplications and using an exclusive lock.  Additionally the error handling is managed by a $ETrap routine wich will look for error data in order to log it

Set $ETrap = "Do Err1^ErrRoutine"

Set obj = ##class(User.tApplications).%OpenId(2,"4",.errors)

Hello Gentlemen,

My Business process connector receive a Oru_01 hl7 message with an ED segment inside (Base64 pdf). How is it possible to extract it and create a pdf file within?
Here is the sample of function I have. I know it doesn't work but if you could help me, it would be perfect. Here is my function, the goal would be it create the file where I want and return me the link of the file.

Method getPdfFromED(req As EnsLib.HL7.Message,segment As %String) As %Status
{ 
    do req.GetFieldStreamBase64(.base64, segment)
    set stream1=##class(%Stream.FileCharacter).

Hello,

I'm using ZEN report to generate a PDF file out a table.

Although, I need to display data from two tables splitted into two different namespaces.

So, I created a process that fetches all the data I need and then calls the PDF class and generates the stream out of it.

My question is, once I've got my list of objects. How can I transform it into a ResultSet, in order to display in the report ?

Thanks for your answer.

I successfully got everything in this guide to work:  https://community.intersystems.com/post/ensemble-rabbitmq-java-client-q…

I am now using the information I gained from this guide along side with this guide:

https://www.rabbitmq.com/tutorials/tutorial-one-spring-amqp.html

I am running into an issue though. In the RabbitMQ guide I just posted, they have a "Receive message" functionality. I use that alongside with the SendMsg from Ensemble method in the InterSystems guide.

I know it's late, but I really love the advent of code theme each year to find some project ideas to go out and code something and push myself.

I had the intentions of completing the AOC 2018 before the new year, but I've got 2 young kids (1yo and 4yo), so most nights I just want to sleep.

I've been looking at this on my half hourly commute each day before and after work.

So whilst doing this, I found not many people had posted what they had done and in previous years.

ˮ This is one of my articles which was never published in English. Let's fix it!

Hello! This article is about quite a practical way of developing InterSystems solutions without using the integrated tools like Studio or Atelier. All the code of the project can be stored in the form of "traditional" source code files, edited in your favorite development environment (for example, Visual Studio Code), indexed by any version control system and arbitrarily combined with many external tools for code analysis, preprocessing, packaging and so on.

I have a problem,ExtentSize,Selectivity etc is stored in class definition.

I have multiple namespaces with globals maped and only one class definition for All, for example Orders.

Order definition is only one,mapped to main namespace,but in different namespaces have different ExtentSize etc.

I am taking over a production system that had some HSLIB and other database routine and class files modified. However, I do not know what was modified .

I developed a routine that allows me to load each database in our production instance and compare it against a default instance using the SIZE attribute. This allowed me to generate a list of files where the .INT file size in production does not match the file size in the default instance. However, doing a spot check of the .cls or .mac files indicates that in some cases these files are identical, just the intermediate files are different.

Hello Gentlemen,

As you can read on the title, my question is to know how to retranslate the hl7 message into a string and so to remove the '\E' that are inside. A example/picture worth more than a thousand word.
OBX|1|RP|ECG||CARDIO ECG^APPLICATION^PDF^^\E\\E\sitehopital.org\E\files\E\cardio\E\022018\E\GE274583.PDF|

As you can see, the escape character \E is used by hl7 message in the purpose to authorize a character '\' just but I don't want it in my program... Is there any function that retranslates this format into a "normal" format?

Faithfully,

Thomas

I'm getting this compilation error:

Kompilieren der Klasse digi.packet
FEHLER #5002: Caché-Fehler: <FUNCTION>zLockUse+5^%ExtentMgr.GlobalRegistry.1
  > FEHLER #5030: Während der Kompilierung von Klasse 'digi.packet' ist ein Fehler aufgetreten

when importing one of my classes on the production server into one particular namespace:

• the class compiles just fine on dev pc.
• the class compiles just fine also in any other namespace of the same cache instance. So, looks as a problem of this particular namespace.

In my routine when I call set filestream.FileName = filename, I get an error

"cn_iptcp://localhost:56773/USER/%Stream.FileBinary.1.INT" does not exist on the Server

I successfully instantiate the %Stream.FileCharacter object. 'filestream' value is '1@%Stream.FileCharacter'. But when I debug the code, the step where I try to set the file name fails. 

The port number for local host looks good for my current instance. I have tried a few variations, such as using the method FileNameSet(). But this did not work either. 

My routine exists in the USER namespace, as indicated in the error.
