Hi,

I was understanding the cluster configuration supported by the Cache. Have couple of queries around that:

1. In Cache version 2018.2, there is a shrading concept which splits the data of a Master Data server into multiple small data server which store shraded data.

GlobalSummit too close now, so many people going to be there from so many companies. I'm sure that somebody already uses Docker or even Kubernetes in their work, I do. And would like to share my experience and thoughts about what could be better. And want to hear other people about their experience, how you use Docker, what issues have you faced and how did you solve it. I think InterSystems will help us to find time and place when we could do it, and hope @Luca Ravazzolo will join us.

It is possible to update Cache object property from Python using the following Python code, with import of intersys.pythonbind3:

my_object.set("my_property",["A","B","C"])

However, I am unable to save 2D %List with 2D Python array like the following:

my_object.set("my_property",[["A","B","C"],["1","2","3"]])

I am not sure whether this is Python-Cache bind flaw or design issue. Is there any alternative/ workaround to do the same for above?

Presenter: Michael Broesdorf
Task: Use the Internet of Things in a business application
Approach: Demonstrate incorporating device-generated messages into a business process, and using that information to trigger physical events

(Session Sequence: Dependent on EOPEN) IoT may be the most hyped idea of the year, but how do you actually make use of it in your business applications? This session gives a detailed demonstration of incorporating device generated messages into an business process, to interact with your business applications and triggering physical events as a part of a business process.

Content related to this session, including slides, video and additional learning content can be found here.

So, you checked your server and saw that IRISTEMP is growing too much. There's no need to panic. Let’s investigate the issue before your storage runs out.

Step 1: Confirm the IRISTEMP Growth Issue

Before assuming IRISTEMP is the problem, let’s check its actual size.

Check the Free Space

Run the following command in the IRIS terminal:

%SYS>do ^%FREECNT

When prompted, enter:

The IKO allows for sidecars. The idea behind them is to have direct access to a specific instance of IRIS. If we have mirrored data nodes, the web gateway will (correctly) only give us access to the primary node. But perhaps we need access to a specific instance. The sidecar is the solution.

Building on the example from the previous article, we introduce the sidecar by using a mirrored data node and of course arbiter.

I've been preparing to take the InterSystems HL7 Interface Specialist certificate and on the page that explains the cert it lists one in-person class and one online course. I've been through the suggested online course but when I read through the practice questions there are a lot of things that aren't covered or mentioned in that course. Naturally I could go digging through the documentation but there is no specific guidance about what things to study.

Working with Named Pipes

While creating my latest examples for the JavaContest I faced the need
to communicate with my code from a program in IRIS to my Java code.

Communication with |CPIPE| worked as READ or WRITE but not both?
In the Documentation Named PIPEs are explained rather shortly.
"Once open, a pipe acts like an ordinary device." Not so precise.
I failed to achieve my expected READ/WRITE as TCP would offer.

Why I've decided to write this

Once again I had a challenge that costed me some time and a lot of testing to reach the best solution. And now that I've managed to solve it, I'd like to share a little bit of my knowledge.

What happened?

In a namespace there were a lot of similar classes, so to make them simpler there were a superclass with comon properties. Also, there are relationships between them. I had to export one of them to JSON, but I couldn't change the superclasses, or I would break down the flow of many other integrations.

Kidney Disease can be discovered from some parameters well known to the medical community. In this way, in order to help the medical community and computerized systems, especially AI, the scientist Akshay Singh published a very useful dataset for training ML algorithms in the detection/prediction of kidney disease. This publication can be found on the largest and best known data repository for ML, Kaggle at https://www.kaggle.com/datasets/akshayksingh/kidney-disease-dataset.

Hi,

Is there a way to find the median in Intersystems Cache SQL? I know it is not available as an aggregate function. Also in SQL Server I could try something like: 

SELECT
(
 (SELECT MAX(Score) FROM
   (SELECT TOP 50 PERCENT Score FROM Posts ORDER BY Score) AS BottomHalf)
 +
 (SELECT MIN(Score) FROM
   (SELECT TOP 50 PERCENT Score FROM Posts ORDER BY Score DESC) AS TopHalf)
) / 2 AS Median

However, there is no PERCENT Keyword in Cache as well. Any suggestions?

Thanks

We have an implementation with a bunch of users, and a bunch of namespaces, both of which are added and removed frequently, and the users have restrictive perms in the namespaces (lets just say, not %All)... and the users are utilizing the VSCODE extension for development.

Per the instructions and the user experience, we need to run:

GRANT EXECUTE ON %Library.RoutineMgr_StudioOpenDialog TO ${user}

For ... each Namespace, and additionally %SYS for Web Apps.

Hi,

I have a PV1 repeating field that can contain multiple or a single value. I'd like to always pull the last value in the field but am not sure how to configure this in my DTL.

The repeating field is in PV1:50().1

Could somebody shed some light on this?

Examples:

|15081942~15081951~15108961~15280550|

|15081947|

|15081939~15081940|

Thanks

Hi,

Business Rules can define a context object, whose properties are exposed and used in the expressions of the rules. For example, my context object is an object with 3 properties. PropA, PropB and PropC.

When constructing my rules, I can call a custom function, and I have one I built myself called 'myFunction' which takes arguments and I pass in properties of my context object. (I can pass in the value of the context object's PropA, B or C).

Hi Developers!

This post describes how you could publish your InterSystems application on Open Exchange.

What is the InterSystems application?

It could be anything, which is built with InterSystems data platforms or to help work with InterSystems data platforms: InterSystems IRIS, InterSystems IRIS for Health, InterSystems HealthShare, InterSystems Ensemble and InterSystems Caché. This could be tools, frameworks, adapters, examples and business solutions.

Why publish on Open Exchange?

InterSystems Open Exchange is an "App Central" for the solutions in InterSystems. It's the first place where the developer goes to look for tools, frameworks, and examples on InterSystems IRIS. And Open Exchange brings the added traffic to your solution which could be converted into leads.

We are having a set of business development tools for published Open Exchange applications. This definitely makes your InterSystems application more noticed.

Submitting an application

Suppose you have a library with open source published on Github which you want to publish on Open Exchange. For the purpose of a demo, I'll fork this remarkable project of @Peter Steiwer ObjectScript-Math which I forked and renamed to object script-super-math.

I want to create a CSP page that returns a pdf.
The pdf is identified by a pdftoken parameter.

My goal is to validate the token and return the pdf (ContentType=”application/pdf”) if the token
is good and return a text error message "Bad Token" (ContentType=”text/plain”) if the token is missing or bad.

My issue seems to be associated with ContentType. I can define one ContentType that works for the pdf or the error message.
I am unable to change the ContentType.

Any assistance is appreciated.
