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:

A feature I recently used in working on ISC internal applications is the ability to send emails on behalf of someone. This is useful when generating system notifications from an application when you want some of them to show up as being from a specific person, perhaps posting comments on a work ticket.

In my case I was updating our facilities work order system for tracking requests. Normally all notification emails are sent from the same noreply email address. I wanted to change that so comments added from the original requester would show up as being from them and stand out.

Hello community!

I have a question about the %OnSave method of a class. We have a class that has two properties that are classes.

Class A

Class B

Class C

Class A.PropertyB as Class B

ClassA.PropertyC as Class C

Classes B and C also need to point back to Class A - it's just the way it is. We need to be able to use any one of these classes and get to the others (it's actually even more complicated than this, as Classes B and C also have a PropertyC and PropertyB as well, respectively) :

How can I get a terminal connection to Caché server from Atelier?

Is it possible?

Hi Guys,

Can you please advise on the below queries.

Query 1:

Example 1:

 S a="345",b="arun",c="kumar",d="hi",e="yello",f="orange"

Example 2:

S a="345"

S b="arun"

S c="kumar"

S d="hi"

S e="yello"

S f="orange"

Can you please advise me, which one is performance wise is better.

Query 2:

Example 1:

S:a=1 R="Arun"

Example 2:

I a=2 R="Arun"

Please advise me, which one is giving better performance in this.

I've never had a problem changing the content-type on a response using either %CSP.Page or %CSP.REST until now. No matter where I put the line to set the content-type to "application/json", it stubbornly emits a content-type of "text/html".

A few customers have seen this happen, so I thought it would be worth mentioning here on the Developer Community. This could affect users running versions between 2014.1.3 and latest who install or upgrade Wireshark. There is a bug in the Visual C++ 2013 redistributable shipped with the current Wireshark 2.2.1.

This is from Microsoft’s bug report https://support.microsoft.com/en-us/kb/3138367 :

Caché Localization Manager

CLM is a tool for localization/internationalization/adding multi-language support to a project based on InterSystems Caché.

Imagine that you have a ready project where all the content is in Russian, and you need to add an English localization to it. You wrap all your strings into resources, translate them into English and call the necessary resource for Russian or English when necessary. Nothing tricky, if you think about it. But what if there are lots of strings and there are mistakes in Russian (or English)? What if you need to localize in more than one language – say, ten? This is exactly the kind of project where you should use CLM. It will help you localize the entire content of your project into the necessary language and retain the possibility to correct entries.

Trying my first REST call operation to our internal EMR (Epic) server, and I am receiving "ERROR #6097: Error '<READ>Read+28^%Net.HttpRequest.1' while using TCP/IP device '9999'" when I attempt to test my operation. When I look up the General Error Messages for 6097 I am seeing...Error '%1' while using TCP/IP device $zu(189,1)='%2'. What does this mean?

Hi,

suppose a part of my mdx query is [DIMENSION].[H1].[LEVEL1].CURRENTMEMBER.Property("PROP1").

If the source property of PROP1 is also used as a dimension level somehwere in the cube, this query will return a key to the entry in the coresponding star table.

Does anybody know how I can follow that key and display the real value value?

I understand RecordMaps can be used to send delimited files through a production without custom coding. The data segments are delimited by tilde character followed by $Char(10) in Linux/Unix. When I test the same IO data in Windows, I have $Char(13) and $Char(10) instead of just $Char(10). I like to use just tilde character for record delimiter and ignore $Char(13) and $Char(10) between the tilde and the leading data of the next segment / record. Is this good idea or not if someone wants to generate classes will it override code?

I have a class to track data changes.
As it becomes slower and slower to find last changes I think I need an index.
The 2 classes are just simplified reality.
HowTo ?
