InterSystems ObjectScript is a scripting language to operate with data using any data model of InterSystems Data Platform (Objects, Relational, Key-Value, Document, Globals) and to develop business logic for serverside applications on InterSystems Data Platform.
We are trying to migrate old server to new infrastructure and need to sync all the DTL cls from old one to new one. There are hundreds of DTL in system and we tried to export from production but cannot select all at once which might cause some missing classes. Not able to connect to studio or atelier with that server neither. Is there any way that we are able to do mass export from system which will save some effort? Please let me know your thoughts. Thanks.
Do you know how to create workflow users and roles programmatically? I use Docker for test deploy and I need to set up IRIS Interoperability using the install script.
Maybe do you know how to import/export already existing workflow users and roles?
Last weekend I had been testing the newborn csvgen module and was looking for a CSV file to test - thus I came across an interesting datafile on Data.World with Game of Throne episodes statistics. Death statistics. These folks documented all the murders through all the 8 seasons and noted where, who, from what clan with what weapon had killed another one.
So I imported it and made an IRIS Analytics dashboard.
Don't worry, Jon, with this dashboard we can figure out something ). See the details below.
set reader=##class(%XML.Reader).%New() set statuscode=reader.OpenFile(file) if $$$ISERR(statuscode) {do $System.Status.DisplayError(statuscode) quit $$$NULLOREF}
After all these years of doing basic Ensemble work, I am just beginning to venture into using Cache Tables instead of either Data Lookup tables, or what I know of Outside SQL tables using JDBC. I have several Cache SQL tables that I am building for a project I am working on.
Some time ago I got a WRC case transferred where a customer asks for the availability of a raw DEFLATE compression/decompression function built-in Caché.
When we talk about DEFLATE we need to talk about Zlib as well, since Zlib is the de-facto standard free compression/decompression library developed in the mid-90s.
Zlib works on particular DEFLATE compression/decompression algorithm and the idea of encapsulation within a wrapper (gzip, zlib, etc.). https://en.wikipedia.org/wiki/Zlib
This is a sample to use %JSON.Adaptor class available in IRIS to produce a snapshot of your object.
The sample consists of 2 classes that are variations of what was known in Caché/SAMPLES as Sample.Person. Be aware that the possibilities are limited by %JSON.Adapter and how you make use of it.
Once in place, you create some test data by Populate(). You select an object and take a snapshot. You apply changes to your object and take another snapshot. And see the difference.
I am using the Java Binding to connect a Java Middleware Application to Cache. Originally I was using a CacheListOfDataTypes (JAVATYPE = "java.lang.List") object to bring data back. I was tasked with encrypting the data using AES and I was using the AESCBCEncrypt function on the List elements (up to 20k characters for each element) to bring it back before concatenating it on the middleware. This almost worked. Like 95% of the characters were being decrypted correctly but some text was coming back garbled. I couldn't understand how this was happening.
A unit of ObjectScript code (a ClassMethod, say) may produce a variety of unexpected side effects by interacting with parts of the system outside of its own scope and not properly cleaning up. As a non-exhaustive list, these include:
We are glad to invite every developer who uses ObjectSript and VSCode plugin to the second webinar hold by the VSCode ObjectScript plugin developer on May 26 at 11:00 EDT.
I have a class method that accepts a global parameter but when I attempt to order this global, the global name is listed as undefined. I can execute $DATA(pGlobalName) successfully.
InterSystems ObjectScript is perhaps the best language on the planet to deal with globals - and it is an interpretable language.
Yes, it has a compiler. But even the compiler can compile some lines in ObjectScript which will then fire as bugs during the runtime.
There are some technics on how to avoid that such as unit testing, coding guidelines and your coding experience, of course ;)
Here I want to present to you the yet another approach to how you can reduce the number of errors in your ObjectScript runtime and enforce coding guidelines - it's an ObjectScript Quality tool developed by Lite Solutions, InterSystems solution partner.

Hello all, I have a question about constucting thousands of clones, and scope.
In my code, I'm looping through a database, say 200k+ objects, and creating a clone of each object (we need to evaluate a modified clone of the object, but not account for what's on disk).
In this edition of InterSystems IRIS2020.1 Tech Talks, we put the spotlight on Integrated Development Environments (IDEs). We'll talk about InterSystems latest initiative with the open source ObjectScript extension to Visual Studio Code, discussing what workflows are particularly suited to this IDE, how development, support, and enhancement requests will work in an open source ecosystem, and more.
As discussed in previous parts of Package Manager stories to turn your IRIS application into a deployable package you just need to introduce the module.xml file into the root folder of the repository and describe all the resources.
I’m pleased to introduce you to a new project template on Open Exchange which contains examples of how to make different types of resources of your InterSystems IRIS application a part of the ObjectScript package and so make the deployable ObjectSctipt package.
Let's see how you can describe your application resources using this template project as an example.
Using the IRIS native API for Node.JS was the opportunity to present a MicroService operating in a Docker container. A demo video is now also available to watch the demo in operation.
