Question Scott Roth · Oct 31, 2018

I am working on my first REST operation concept and had a question about the Property Parameters. If I put a value in CAPTION, does that mean that when I use it in my call that it will come out in the URL?

For example...

Property enumerationType As %String(CAPTION = "enumeration_type");

Then in my operation...

Set tURL=..Adapter.URL_"?q="_pRequest.enumerationType

so when it builds the URL it looks like...

Here I’ll walk you through the process of creating a simple Node/Express API and connect it to a InterSystems IRIS instance.

I won't go into much detail about how to work with any of the technologies I will mention in this tutorial but I will leave links, in case you want to learn more.

The objective here is to give you a practical guide on how to set up and connect a node.js back-end API to IRIS.

Before we get our hands dirty, make sure you have Node.js running on your machine. So I'll check:

➜ node --version
v8.12.0

Version 8.12.0 is the current LTS (Long Term support) version of node.js.

Question Satish P · Oct 25, 2018

Hi,

We are trying to write an external backup application to backup Cache Database. After going through the Cache DB documentation, we have found that in Backup.General class there are methods for creating snapshot (Freeze/Thaw) which is required during backup. Are there REST APIs for the same?


Also we have the option of selecting individual DB instances in the management portal.  What are the methods/APIs of getting the DB list, so that user can select individual DB instances in an external backup application ? Do we have the methods/APIs to freeze/thaw the individual DB instances ?

Thanks!

Question Shaun Murray · Oct 11, 2018

My main goal is to be able to create reports and alerts in my SIEM based on what individual searched for and accessed what patient records, and when.

Does anybody have any experience with this? I've been ingesting audit logs in to Splunk but I'm having a hard time getting useful data.

I looking to gain insight on if I can trigger a SMS text to a Clinician

New to HealthShare and trying to get the process for setting up a message.

Simple use case

Alert a Clinician if a patient meets specific requirements via an SMS text message.

I have set up a test physician in our dev environment, and enabled push notification on the Edges fro the MPI update manager.

Based off of the HEPUSH documentation.

Any direction to documentation or steps is greatly appreciated.

Thanks,

InterSystems IRIS supports publish and subscribe message delivery. Publish and subscribe refers to the technique of routing a message to one or more subscribers based on the fact that those subscribers have previously registered to be notified about messages on a specific topic.

This article demonstrates how several InterSystems IRIS capabilities can work together:

In this article we would send emails about:

  • New workflow tasks
  • Unassigned workflow tasks
  • Uncompleted workflow tasks
  • Ensemble alerts

Email recipients would be determined using Publish/Subscribe operation and each user would receive only digest email whenever possible.

Question Stephen Wilson · Oct 8, 2018

I think I already know the answer to this but I thought I'd ask anyway. So the Node.js adapter allows you to perform operations directly on Globals. Does the InterSystems.Data.CacheClient.dll or InterSystems.CacheExtreme.dll provide a mechanism to access Gobals directly or are you accessing globals via Caché ObjectScript classes?

Question William Proctor · Sep 27, 2016

All responses are appreciated.  I am new to both scripting and CACHE so please bear with me.  I am setting up a nightly backup script for freezing cache then backing it up and then thawing it back out.  Currently when I enter the freeze command I am getting a response of access denied even though my id has %all access.  I've tried passing the userid/password as a parameter in the externalfreeze command and passing it from a file.  I've used my id and lastly I used the _system id in the file.  What ID should I use for this or am I passing it wrong?

Question Tuan Minh Do · Oct 4, 2018

Hello,

I am a beginner with Object Script and I hope anyone can help me solving my questions.

1. Is there a way to time a loop in Object Script? 

2. My code leads to the following error, even though it executes the method.

Is there a way to ignore this specific error, so that I can repeat my code in a time loop over and over again without stopping?

Question Edward Jalbert · Jul 10, 2018

Newbie question.

We have a desire to leverage apigee to do a call to our MPI system. 

Not sure if this is something we can do via HealthShare.

Anyone doing a soap request or restful call from InterSystems through Apigee? 

If I am overlooking the obvious (documentation) any guidance is greatly appreciated.

Thanks in advance

Can anyone tell me where to find good resources to learn Caché besides InterSystems.  I am  looking foe material (ie books, white paper, exercises, ect).  There does not seem to be a lot of information on Caché.

Thank you for all of your help

Question Santhosh Gladson · Sep 20, 2018

Hello Experts,

I have a silly question of using InsertParam method and usage. I understand it is name value pair. I am using GET method to send a url and to get the details from server. URL has multiparameter

URL -  api/Identifier/Image/?Verify.EDD={EDD}&Verify.Ethnicity={ETHNICITY}

I have used the URL in a method and called that method directly in the business operation. I am using Insertparam method -

do httpRequest.InsertParam("EDD",..Data.Verify.EDD)
do httpRequest.InsertParam("ETHNICITY",..Data.Verify.Ethnicity)

where httpRequest is an object of %Net.HttpRequest class

The following post outlines a more flexible architectural design for DeepSee. As in the previous example, this implementation includes separate databases for storing the DeepSee cache, DeepSee implementation and settings, and synchronization globals. This example introduces one new databases to store the DeepSee indices. We will redefine the global mappings so that the DeepSee indices are not mapped together with the fact and dimension tables.

Introduction

Any election is a highly mysterious process, and when you look at its results, the overall picture is not quite clear. I decided to put them, region by region, on the map of Moscow using InterSystems technologies that offer both storage and data analysis functionality. In this particular case, I used InterSystems Ensemble, a platform for application development and integration, but you can also build this solution using the multi-model InterSystems Caché DBMS, as well as InterSystems’ new product called IRIS Data Platform.

Question Galena Teneva · Jul 5, 2018

Hi,
it is possible to convert a csv file to json file?

I want to stream json files and output the data as it comes in from the files. So my files are "csv" type and I want to convert these files to "json" type.


I can read csv file as follows:

ClassMethod ReadFile()
{
    set stream = ##class(%Stream.FileCharacter).%New()
    set sc = stream.LinkToFile("*.csv")
    do stream.Rewind()
    while'stream.AtEnd {
        set line=stream.ReadLine()
        write line,!
}
What should I add to convert it to "json" and read it again?

Thank you

Generally speaking, InterSystems products supported dynamic objects and JSON for a long while, but version 2016.2 came with a completely new implementation of these features, and the corresponding code was moved from the ObjectScript level to the kernel/C level, which made for a substantial performance boost in these areas. This article is about innovations in the new version and the migration process (including the ways of preserving backward compatibility).

Question tom whalen · Sep 7, 2018

Ive been asked to investigate Intersystems Cache' for a new software initiative and was hoping to be able to download a limited-use or dev license to kick the tires but I need it for a couple of specific OS builds.  AIX and Linux (CENTOS).  I don't see a place to download specific versions, other than Windows, various builds of Unix and that's about it.  Can someone give me some guidance on how to make sure I'm downloading the right item to build some test instances with?  

thank you in advance :)

Question Eduard Lebedyuk · Aug 28, 2018

Let's say I have a list structure:

set list = $lb("stri,ng", $c(0), 2)

I want to replace all $c(0) elements with empty elements, so my list would look like:

set list = $lb("stri,ng", , 2)

What's the fastest way to do that?

Question Eduard Lebedyuk · Aug 29, 2018

I have a list

set list=$lb(1,$c(0),2)

How do I replace $c(0) with an empty element?

My list should look like this:

set list=$lb(1,,2)

I tried using $list but it either replaces the element with an empty string:

set $list(list,2)=""
zw list

Resulting in:

list=$lb(1,"",2)

Or removes the element altogether:

set $list(list,2,2)=""
zw list

Resulting in:

list=$lb(1,2)

Question Stefan Cronje · Aug 4, 2018

Hey folks,

I am new to IRIS and cloud platforms. I've done the InterSystems IRIS Experience on the learning site and read a lot of the online documentation. What I am unable to figure out is which type of package or option you will use on the cloud provider.

AWS for example, has AWS EC2, Elastic Beanstalk and some other products geared towards Docker containers.
Azure has Kubernetes and some other options.

Question Virginia Rogers · Jul 24, 2018

I have a web application and one of the CSP pages contains the following snippets:

<script language='javascript'>
function SubmitForm(pid,sid) {
//code to process form

alert ("study saved");

self.document.location="newpage.csp";

}

</script>

<form name="Studyform"  method="post" onsubmit='return SubmitForm(#(SubjObj.%Id())#,#(StudyObj.%Id())#);' >
<!-- form contents -->

</form>

The form is correctly processed, the object is saved, and the alert appears, but the new page does not get loaded and I cannot figure out why.

Any suggestions?

Question Scott Underwood · Mar 31, 2017

Is there a way to graphically edit BPL processes, or do we still need to use Studio for doing that? 

Looking at the documentation, it appear there should be an Atelier BPL editor option available under Open With, but all I have is Atelier Class, HTML, INT, and MAC editors. 

There is a BPL editor in the list, but it throws a "Bad editor input" error when trying to open the class file. 

I'm running version 1.0.263 that was installed from the WRC distribution of 1.0.262 and then updated.  The only other plugins installed are the Eclipse XML Editors.

Hello guys,

Based on this article (others as well, but this is the relevant one): http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY…

I have been playing around with the Management Portal deployment tool, which involves:
Ensemble > Manage > Deployment Changes > Deploy and
Production Settings > Actions > Export
Production Settings > Actions > Re-Export

Everything was going fine , until I came across this:
