Hey Community!

We're happy to share a new video from our InterSystems Developers YouTube:

CCR users can now take advantage of an enhanced syntax for substituting pre-defined tokens with live URL links within phase-related text fields. In addition to the existing <env> token which automatically updates to reflect the Environment of the relevant CCR Record, CCR now introduces three new keywords: <smp> , <smpPrefix> , and <homepage>.

For one of our customers I had to integrate with the AFAS imageconnector endpoint /imageconnector/{imageId}?format={format}.
This endpoint returns in a json message with the image as a base64-encoded string property, in addition to the mimetype for the image:

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:

Introduction

My guess is that most IRIS developers create their applications using its native ObjectScript language or, if using an external language, then most likely using either Java, Python or perhaps C++.

I suspect that only a minority have considered using JavaScript as their language of choice, which, if true, is a great shame, because, In my opinion and experience, JavaScript is the closest equivalent to ObjectScript in terms of its ability to integrate with the IRIS's underlying multi-dimensional database.

Mirror Your Database Across the Galaxy with Seeding

Hello cpf fans! This distraction I used the "seed" capability in IRIS to provision an entire IrisCluster mirror, 4 maps wide with compute starting from an IRIS.DAT in a galaxy far far away. This is pretty powerful if you have had a great deal of success with a solution running on a monolithic implementation and want it to scale to the outer rim with Kubernetes and the InterSystems Kubernetes Operator. Even though my midichlorian count is admittely low, I have seen some hardcore CACHE hackers shovel around DATS, compact and shrink and update their ZROUTINES, so this same approach could also be helpful shrinking and securing your containerized workload too. If you squint and feel all living things around you, you can see a glimpse of in place (logical) mirroring in the future as a function of the operator and a migration path to a fully operational mirrored Death Star as the workload matures.

Motivation

I didn't know about ObjectScript until I started my new job. Objectscript isn't actually a young programming language. Compared to C++, Java and Python, the community isn't as active, but we're keen to make this place more vibrant, aren't we?

I've noticed that some of my colleagues are finding it tricky to get their heads around the class relationships in these huge projects. There aren't any easy-to-use modern class diagram tool for ObjectScript.

I have tried relavant works:

What is the actual valid version with ML ??

When I was younger (a question about exactly how much younger is outside the scope of this article), the word “token” meant fun. You see, just a couple of times a year, I would get to go to an arcade and play some amusing video games with my friends.

For example, I'm creating a customer at front end interface. I want to list down all the routines and child sub routines that are called at backend in mumps/cache. What's the best way to do it?

Yes, that's right, a Cache 2017.1 question. Let's all take a trip in the Wayback Machine.

Hi All,

First I want give a Shout Out to @Theo Stolker and @Rupert Young. Because they helped me with the solution.

Hi Community!

We’re excited to announce a brand-new sweepstakes. This time, the theme is:
