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.

Question Guillaume Rongier · Sep 20, 2018

Hi, We recover a large amount of data from an external database (SQLServer, about 1 million rows in JDBC).
However, we have treatment time issue.
This process takes more than 30 minutes whereas on a "classic" SQL Server Management Studio type request takes less than a minute.

While searching on the internet, I came across this article: http://makejavafaster.blogspot.com/2015/06/jdbc-fetch-size-performance.html
It explains how in Java, we can tweak the FetchSize parameter of the JDBC driver to optimize this kind of process.

Question Scott Roth · Apr 12, 2019

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.

Question Mathieu Van Sevenant · Mar 12, 2019

Hello everyone smiley

I have a server configuration in a CSP Gateway installed on a PC (let's call it S2) different from the main one (let's call it S1). This configuration allows me to access a web application that is installed on S1, from a client C asking S2 for this webapp. But for now it works only in HTTP between C and S2, and we would like to use HTTPS (as it already works between S2 and S1).

First here are the tutos found in the doc:

Question Thomas Schroyen · Apr 8, 2019

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

at: https://adventofcode.com/2018/day/2/input

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.

Question Minoru Horita · Apr 11, 2019

In Cache'/Ensemble, by specifying the objectsPackage parameter, dictionaries (and other objects) get projected to tables that can be accessed by SQL queries.

But in IRIS (IRIS for UNIX (Ubuntu Server LTS for x86-64 Containers) 2019.1 (Build 507U) Mon Feb 25 2019 13:47:16 EST), when I created a dictionary with ##class(%iKnow.Matching.DictionaryAPI).CreateDictionary(), it does not get projected to a table.

The class APIs correctly retrieve information about this dictionary.

Am I missing something with IRIS, or is there any issues about this?

I needed to know programmatically if last ran failed or not.

After some exploring, here's the code:

ClassMethod isLastTestOk() As %Boolean{  set in = ##class(%UnitTest.Result.TestInstance).%OpenId(^UnitTest.Result)  for i=1:1:in.TestSuites.Count() {    #dim suite As %UnitTest.Result.TestSuite    set suite = in.TestSuites.GetAt(i)    return:suite.Status=0 $$$NO  }  quit $$$YES}

Question Neerav Verma · Apr 12, 2019

Hello All,

There are few tools for SQL optimization available and even query builder has Show Plan to give us an estimation of the resources needed to execute.

For Methods - Is there anything similar ??

I would like to see a similar approach as to the time taken for method to execute.

Is Studio Debugger only option ??

Question David.Satorres6134 · Apr 11, 2019

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!

Question Yaron Munz · Apr 11, 2019

In a Business Process (BPL) I noticed that if I 'm using a "scope" to handle errors  then inside the "scope" when a "call" is used, the "request" and "response" action (i.e set for callrequest.prop = request.prop & response.prop = callrespones.prop does NOT work !
The result is that the values of those properties in the callrequest  are nulls (I do see the properties names in the content of the callrequest message)

Question Chip Gore · Apr 4, 2019

Hi -

I was wondering how if the "old FHIR gateway" works with the latest release of HealthShare Information Exchange. Since there is an impact on the amount of storage needed to use the "FHIR Gateway 2 which uses the Operation Data Store (ODS)", my question is how (if at all) can FHIR access to Information Exchange work without ODS?

Thanks
