I'm trying to convert a CSV inbound to an HL7 MFN^M16 outbound. I know I'm using book information as the CSV but I don't think that matters. Please let me know if that's incorrect.

My service is reading the file in just fine and when I don't have a DLT transformer the raw message passes through to outbound file folder just fine. However, when I include a basic DLT that simply copies a couple of fields over I get the "Ens.StreamContainer" error. Everything also seems to be good in the Record Mapper.

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

• Git 101
• Git flow (development process)
• GitLab installation
• GitLab Workflow
• Continuous Delivery
• GitLab installation and configuration
• GitLab CI/CD

In the previous article, we covered Git basics, why a high-level understanding of Git concepts is important for modern software development, and how Git can be used to develop software. Still, our focus was on the implementation part of software development, but this part presents:

• GitLab Workflow - a complete software life cycle process - from idea to user feedback
• Continuous Delivery - software engineering approach in which teams produce software in short cycles, ensuring that the software can be reliably released at any time. It aims at building, testing, and releasing software faster and more frequently.

In my previous article, we reviewed possible use-cases for macros, so let’s now proceed to a more comprehensive example of macros usability. In this article we will design and build a logging system.

Logging system

Logging system is a useful tool for monitoring the work of an application that saves a lot of time during debugging and monitoring. Our system would consist of two parts:

• Storage class (for log records)
• Set of macros that automatically add a new record to the log

I was curious if application partners were developing their own task managers for scheduling background tasks, or using the built in task schedule that is part of the Cache platform.

For those that are using the Cache task manager, what has been your method for distributing default tasks that your application needs during initial install as well as upgrades? Are you distributing an export of the %SYS.Task object, or perhaps you are distributing an installation script that adds a task to the task scheduler when it is first run?

I need to download InterSystems Caché ODBC Data Source 2018 and I can't.
I want to know where I can download it.

InterSystems IRIS 2019.1 has been out for a while and I would like to cover some enhancements for handling JSON which might have gone unnoticed. Dealing with JSON as a serialization format is an important part of building modern applications, especially when you interact with REST endpoints.

Hello!

Are there any short ways of serializing COS entity to the string? I am searching for something like .$toJSON() , but I need Caché 2013.* support.

The one way I supposed to work is to use $listbuild:

set str = $LISTTOSTRING($LB(1,2,3,",",5))
set list = $LISTFROMSTRING(str,",")
zw list
list=$lb("1","2","3","","","5")

Hello Caché-Community,

where can I download the current ODBC Drivers for InterSystems Caché.
The links in the following post don't work anymore:

My Ensemble instance is reporting its status through SNMP in Dutch even though my system language is English. Can I change Ensemble's locale somewhere in the Management Portal?

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

GraphQL is a standard for declaring data structures and methods of data access that serves as a middleware layer between the client and the server. If you’ve never heard about GraphQL, here is a couple of useful online resources: here, here and here.

In this article, I will tell you how you can use GraphQL in your projects based on InterSystems technologies.

Checking if Directory or File Exists:

Outlined below is an example of how to check if a directory exists:

Set directoryName="c:\temp\nosuchdir"

/* Check for existence of a directory - Return Value:  0 - directory does not exist;  1 - directory does exist  */

Set directoryExists=##class(%File).DirectoryExists(directoryName)

If ('directoryExists)  // do the processing for when a directory does not exist

Outlined below is an example of how to check if a file exists:
