Wanted to share something I learned recently while working on a problem. We needed to add and change some Business Hosts in one of our edge productions.

In the past, we simply added the production class to CCR and then spreading it around. But there was a problem because different developers were working on different things, and we only wanted to include only the relevent production changes onto the CCR.

Here's a little piece of code that can help add new things to an existing production:

It can be obtained using AllFields query of %SYS.ProcessQuery class.

When creating custom Business Hosts, it's often necessary to add properties to the class for additional settings that will be used in the initialization or operation of the host. The property name itself isn't always very descriptive, so it's an advantage to have a custom caption display with the field.

In Caché, it was fairly straightforward:

Now the Classes/Rutines/DeepSee files will be automatically exported to the working directory after saving or compiling and files will be automatically deleted .

Installation

To install isc-dev , you just need to download and import the file isc-dev.xml from last release.
Some ways to import isc-dev .xml file:

• Go to Management Portal -> System Explorer -> Classes -> Import and select the XML file.
• Drag the file over Studio.
• Terminal command:

NS>do $system.OBJ.Load("yourpath/isc-dev.xml","ck")

• Get it from Package Manager Client:

NS>zpm
zpm: NS>install isc-dev

How to enable this feature:

• After importing the class in the target namespace, run the following method to set up the working directory:

NS>do ##class(dev.code).workdir("/path/to/your/working/directory/src/")

• Go to Management Portal -> System Administration -> Configuration -> Additional Settings -> Source Control.
• Select the target namespace and set the dev.FileManExtension class as the main one and save it.
• Try to create a new class in the studio and save/compile it
• Enjoy!

The InterSystems ObjectScript language does not allow you to define methods of the same name with different arguments. It is generally classified as a programming language called a dynamic language.

In ObjectScript, you can freely control which arguments are used when executing a method, so unlike languages ​​such as Java, which are not dynamic programming languages, there is no need to strictly distinguish methods by the number of arguments at the compilation stage.

Countermeasures against SQL injection have been published on various websites, but we believe that it is possible to prevent SQL injection in applications using InterSystems SQL as well as other RDBMS by implementing these countermeasures appropriately. In addition, InterSystems Data Platform (hereinafter referred to as IRIS) incorporates several measures that make SQL injection more difficult than general RDBMS.

This is an article on the InterSystems FAQ site.

1. Export API

a. Use $system.OBJ.Export() to specify individual routines to export. For example:

The format to specify is routine name.extension, and the extension is mac, bas, int, inc, obj.

Errors during export are stored in errors.

Using the Config.Configuration class and SYS.Database class methods, you can create and register a namespace database from the terminal.

Below is a series of execution examples that create database file /CacheDB/AAA/cache.dat and register database AAA and namespace AAA in the configuration file (cache.cpf).
* Execute in the %SYS namespace. *

* Make sure that this script runs as the user that is used for all IRIS processes to ensure that the directory has appropriate ownership and permissions *

Migrating data to another system takes two steps.

1. Migrating class definitions

To migrate the class definition to another system, export it to a file in XML format or UDL format (extension .cls).

The export procedure in Studio is as follows.

Tools > Export

> Select multiple classes you want to migrate with the [Add] button

> Check [Export to local file]

InterSystems Production Monitor is a page in Management Portal to display monitoring information for the current running production. I like the page as it comes, but one size does not fit all.

On May 13, 2022 I read this post on Developer Community:

Introduction

Say you have a receiving system that accepts HL7 and provides error messages in field ERR:3.9 in the ACK it returns. You require a different reply code action depending on the error message, however the Reply Code Actions settings for the operation do not provide this level of granularity. One option could be to create a process that takes the ACK and then completes the action you were expecting, however things can get a bit messy if the action is to retry the message, especially when trying to view a message trace.

1.Background

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 type of 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.

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.
