SSH framework is a relatively representative framework of Java, which was popular many years ago. There are Struts+Spring+hibernate and Spring MVC+Spring+hibernate. Of course, I used the second one in college. If I can connect IRIS to Hibernate as a library, does it also mean that IRIS can be developed using SSH framework in theory?
Visual Studio Code (VSCode) is the most popular code editor on the market. It was created by Microsoft and distributed as a free IDE. VSCode supports dozens of programming languages, including ObjectScript, Until 2018, Atelier (based on Eclipse). It was considered as one of the main options to develop InterSystems products.
1.1 I met a few project that their interface servers were crashed. Cutoms wanted resume server as fast as we can. their servers are running at lan,and they can't use git,there are some namesapce in the server running different service,and usualy there is only one server.
1.2 In the message,it has property in typeof characterstream,as you know,the message search page doesn't support filtering with property of characterstream,so it's so hard to find the messge you want.
The task of handling office documents, namely docx documents, xlsx tables and pptx presentations is quite complicated. This article offers a way to parse, create and edit documents using only XSLT and ZIP.
Why? docx is the most popular document format, so the ability to generate and parse this format would always can be useful. The solution in a form of a ready-made library, can be problematic for several reasons:
library may not exist
you do not need another black box in your project
library restrictions : platforms, features, etc.
licensing
processing speed
In this article, I would use only basic tools for work with the docx documents.
The title of the contest subject is not quite precise but addresses the %Library.classes involved. What is meant is officially named Class Query and is dating back to the early days of Caché. CLASS is used because it is embedded in a COS class. Though there is a precise description in the official documentation it remains rather abstract. My tutorial should guide you step-by-step through a simple example in COS to make it tangible to you
While the classic solution followed rather close the concepts and design of the ancestors Caché / IRIS allows a more modern approach to flexible/multidimensional properties
Though the access is quite comfortable (in traditional COS sense) there are 2 main restrictions that hurt:
#1) It is not saved to disk unless your application includes code to save it specifically. #2) It cannot be stored in or exposed through SQL tables there are some more I'll show how to overcome these limits
One of the reasons why I love Cache and Iris is that not only you can do anything you can imagine, also you can do it in a lot of different ways!!.
Imagine that you have an integration running with IRIS connected by ODBC you probably only run SQL queries but you can also create stored procedures and inside write the code to do everything you can imagine.
I'm going to give you some examples but the limit is your imagination!!
I have experienced that my iris server is gone due to upgrading the docker version when I have built IRIS server on docker container.
Based on this experience, I'd like to show you how to make a backup for the IRIS server before upgrading platform or docker, and the procedure for rebuilding the IRIS in a new environment.
IRIS server backup procedure
When you have finished building for the IRIS server, you need to make a backup.
Released with no formal announcement in IRIS preview release 2019.4 is the /api/monitor service exposing IRIS metrics in Prometheus format. Big news for anyone wanting to use IRIS metrics as part of their monitoring and alerting solution. The API is a component of the new IRIS System Alerting and Monitoring (SAM) solution that will be released in an upcoming version of IRIS.
You are experts in IRIS and know all tricks. The functionality of $ZF(-1,-2,-100, ......) is nothing new to you And you know the limits of this functionality. Both give you access to your local server command line environment. And that's it.
This article is intended to be a simple tutorial on how to create ODBC connections and working with them, since I found starting with them a little bit confused, but I had amazing people to take my hand and walk me through it, and I think everyone deserves that kind of help too. I'm going to divide each little part in sections, so feel free to jump to the one you feel the need to, although I recommend reading everything.
During my recent work on Tutorial - Working with %Query #1 I met a Class Property that is quite different from its same-named relatives. It is there since 'ever' but is rarely used, Related doc doesn't help so much.
InterSystems IRIS versions 2022.2 and newer feature a redesigned functionality for JSON web tokens (JWTs). Once housed under the %OAuth2 class package, the JWT class, along with other JSON web classes (JWCs), now live under %Net.JSON. This migration occured in order to modularize the JWCs. Before, they were closely intertwined with the implementation for the OAuth 2.0 framework. Now, they can be maintained and used separately from OAuth2.
This tutorial is a follow on to Working with %Query It was displaying the content of the input stream chopped in fixed-size chunks. But often those streams are structured and have well-defined separators (e.g HL7) So as a side subject of this tutorial, this chapter shows how to break a stream into PIECES.
It is exactly the same idea as the $PIECE() function for strings with some add-ons.
My previous article introduced you to SQL based Basic Class Query where a clever wizard created all the required code for you and your essential contribution was an SQL statement.
Now we enter the real Custom Class Query thatprovides more freedom but requires a deeper understanding of the mechanic behind the scene. The full code example is again on GitHub
My previous article introduced you to the COS based Custom Class Query. There were some features missing like more lines of the stream displayed and numbered.
If one of your packages on OEX receives a review you get notified by OEX only own YOUR package. The rating reflects the experience of the reviewer with the status found at the time of review. It is kind of a snapshot and might have changed meanwhile. Reviews by other members of the community are marked by * in the last column.
I also placed a bunch of Pull Requests on Github when I found a problem I could fix. Some were accepted and merged, and some were just ignored. So if you did a major change and expect a changed review just let me know.
I'm sharing a tool for data ingestion that we have used in some projects.
DataPipe is an interoperability framework for data ingestion in InterSystems IRIS in a flexible way. It allows you to receive data from external sources, normalize and validate the information and finally perform whatever operation you need with your data.
Looking to breathe new life into an old MUMPS application? Follow these steps to map your existing globals to classes and expose all that beautiful data to Objects and SQL.
At least three different ways to process errors (status codes, exceptions, SQLCODE etc is given in ObjectScript. Most systems have status, but for a range of reasons exceptions are more convenient to manage. You spend some time translating between the various techniques dealing with legacy code. For reference, I use several of these excerpts. It is hoped that they will also support others.
Over the years, I have found myself needing to create multiple HL7 messages based on a single inbound message. Usually these take the form of an order or result from a lab. Each time I have approached it, I have tried to start from scratch under the belief that the previous attempt could have been done better.
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.
