Is there an easy way to open classes in VS Code?

In studio you go open and just type the class name and it opens up the class.

In VS Code need to know the full path, is there a quick way? It is probably the one thing preventing from using VSCode full time (apart from not seeing the .luts or csp files)

These days the vast majority of applications are deployed on public cloud services. There are multiple advantages, including the reduction in human and material resources needed, the ability to grow quickly and cheaply, greater availability, reliability, elastic scalability, and options to improve the protection of digital assets. One of the most favored options is the Google Cloud. It lets us deploy our applications using virtual machines (Compute Engine), Docker containers (Cloud Run), or Kubernetes (Kubernetes Engine). The first one does not use Docker.

Introduction

In the first article in this series, we’ll take a look at the entity–attribute–value (EAV) model in relational databases to see how it’s used and what it’s good for. Then we'll compare the EAV model concepts to globals.

Forwarding Requests in a REST Service

One useful feature of our REST framework is the ability for a dispatch class to identify request prefixes and forward them to another dispatch class. This approach of modularizing your URL map will improve code readability, enable you to easily maintain separate versions of an interface, and provide a means to protect API calls that only certain users will be allowed to access.

Why Atelier? And what about Studio?

I have been meaning to make a post about this topic for a few weeks and the other day an issue came in through the WRC about it so it seems this is a conversation we should be having. I want to begin by taking a few moments to explain "Why Atelier" then we can talk about what this means in the general sense for Studio and Atelier and Caché developers. We have wrestled with what to do with Studio for years. When I moved to Product Management in 2008 this was already a "thing". At the time we could not reach a consensus. Some felt Studio was fine as is.

How the Ensemble Scheduler Works

The Ensemble Scheduler is used for automatically turning on and off business hosts at certain dates and times. You could use it if, for example, you wanted to only run a business host from 9am to 5pm every day. Conversely, if you want do to trigger an event to occurr at a specific time, for example, a job running at 1am to batch up and send off all the previous day's transactions in one file, we recommend other methods such as the Task Manager.

So this may sound trivial, but I'm seeing conflicting information on this topic and hoping to get clarification.

According to Enslib.HL7.Message class definition, the maxlength of RawContent is 10,000 characters. So when using encoding like UTF-8, that is 10KB. When using Unicode, that should then be 20KB.

But then also coming across some forums and documents where 32KB is maximum size before HL7 fields are truncated.

What is the sure way to determine and modify an interface's maximum supported message size?

Hyper-Converged Infrastructure (HCI) solutions have been gaining traction for the last few years with the number of deployments now increasing rapidly. IT decision makers are considering HCI when scoping new deployments or hardware refreshes especially for applications already virtualised on VMware. Reasons for choosing HCI include; dealing with a single vendor, validated interoperability between all hardware and software components, high performance especially IO, simple scalability by addition of hosts, simplified deployment and simplified management.

Hi,

Can anyone point me to an example of a DTL & Class method that can pull a base64 encoded PDF out of a MDMT02 message?

This is really asking for two things;

- how to make a DTL that extracts a specific subfield of an HL7 2.3 message into a message of its own,

and

- how to transform an base64 encoded document into its original binary form for writing to a file.

I'd also love to see an example of an HL7 2.n MDM^T02 ==> HL73.ITK2 non-coded CDA

Hi-

Im curious if there is any specific configuration that has to be done on an IIS web server to serve up RESTful web services.

I have a server that has IIS installed, with the CSP gateway. a second server that has Cache installed on it.

I have configured a web application using the Cache System Management Portal for the web services that has a dispatch class pointing to my dispatch class.

I have created an application mapping in my CSP Gateway Management Portal on the web server such that url's with /webservices prefix are routed to my cache server.

ODBC connection error

Hello,

There is a problem connecting clients through ODBC.

"ERROR [08S01] [Cache ODBC][State : 08S01][Native Code 459]
Connection via cconnect failed:
TCP connect() failed - exception satisfied select().
Reason: (10061, 0x274d) No connection could be made because the target machine actively refused it."

Error sometimes occurs. In cconsole.log there are only messages about high CPU usage.

ODBC and Cache version Cache for Windows (x86-64) 2013.1.4 (Build 801).

Any suggestions?

Hi dev community,

I am currently working on a project to send documents to a RESTful based API that supports bearer
Token Authorization.

When we try to fire a JSON request from our EnsLib.Rest.Operation towards the 3rd party API with a
valid Token we keep receiving Authorization Error codes HTTP 401 back.

If we use the same request and same Token from a test utility such as Postman the request is
successful and we are able to move past the authorization stage.

Hi!

Want to share with you code snippet of try catch block I usually use in methods which should return %Status. 


{ 
 try {
  	$$$TOE(sc,StatusMethod())
 }
 catch e {
 	set sc=e.AsStatus()
 	do e.Log()
 }

Quit sc 
}

Here $$$TOE is a short form of $$$TROWONERROR macro.

Inside macro StatusMethod is any method you call which will return %Status value. This value will be placed into sc variable.

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
  • Why containers?
  • Containers infrastructure
  • GitLab CI/CD using containers

In the first 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.

In the second article, we covered GitLab Workflow - a complete software life cycle process and Continuous Delivery.

In the third article, we covered GitLab installation and configuration and connecting your environments to GitLab

In the fourth article, we wrote a CD configuration.

In the fifth article, we talked about containers and how (and why) they can be used.

In this article let's discuss main components you'll need to run a continuous delivery pipeline with containers and how they all work together.

Two fairly common requests we receive from HL7 customers are (1) how to remove all trailing delimiters for fields and segments in HL7 messages and (2) how to "find and replace" for an entire HL7 message (as opposed to one segment/field at a time). The code sample below shows a custom function that solves for item 1 and by extension item 2 above. In other words the same approach can be used for finding/replacing any sequence of chars in an entire HL7 message, with some tweaks to the custom function.

Greetings,

Is it possible to save Cache code into a file and then run it via command line?

IE: csession [ini] -U [ini] /path/cacheCodeFile.?

What I need to do is run a Cache script from the Linux command line. The script will navigate data to produce a file and then it will exit back to the command line.

Thanks in advance for everyone's time.

In .NET Core you have an option to extend a session using a "sliding expiration". This means that if over half the time has passed and the user actively uses their session then the expiry timer gets reset and the user remains logged in. This can lead to the curious situation where you have an active authenticated user with an expired access token being used in data-access requests.

    Debugging Web

    In this article I'll cover testing and debugging Caché web applications (mainly REST) with external tools. Second part covers Caché tools.

    You wrote server-side code and want to test it from a client or already have a web application and it doesn't work. Here comes debugging. In this article I'll go from the easiest to use tools (browser) to the most comprehensive (packet analyzer), but first let's talk a little about most common errors and how they can be resolved.

    ObjectScript error handling snippets

    ObjectScript has at least three ways of handling errors (status codes, exceptions, SQLCODE, etc.). Most of the system code uses statuses but exceptions are easier to handle for a number of reasons. Working with legacy code you spend some time translating between the different techniques. I use these snippets a lot for reference. Hopefully they're useful to others as well.
