#Debugging

Is there a general way to set a variable XYZ equal to the text of the code line being executed now? Debugger or production. For example, for a code below if code is currently assigning a to 1, XYZ would be equal "S a=1". The same question about a variable containing current routine name.

S a=1

When there's a performance issue, whether for all users on the system or a single process, the shortest path to understanding the root cause is usually to understand what the processes in question are spending their time doing. Are they mostly using CPU to dutifully march through their algorithm (for better or worse); or are they mostly reading database blocks from disk; or mostly waiting for something else, like LOCKs, ECP or database block collisions?

Exported contents of a namespace on one server (classes, include files and lookup tables). Importing that code into a newly created namespace on another server. Both servers Ensemble 2018.1, same build. Export was via InterSystems Studio. Export is around 18Mb in total (XML file sizes).

When importing and compiling on the new server, getting errors as below - with #6301: SAX XML Parser error prominent - on a number of the imported files, all containing data transformations or business processes.

Following 2 local Webinars we had focused on VS Code ["Intro" and "Beyond Basics"; in Hebrew], I prepared for the participants some related links of relevant resources which we sent as a follow-up. Sharing them here as well for the benefit of the Community.
You are all of course welcome to add more useful resources.

I recently realized it's been far too long since I talked about the latest features in the InterSystems ObjectScript Extension for Visual Studio Code.

I'm pleased to announce version 2.12.1 of the ObjectScript extension, containing a number of enhancements that make a developer's life easier. Some highlights are described below, including the #1 requested feature from Global Summit -- XML import!

Someone may have asked this before but is there a way to return the TRACE statements that we have placed in the Data transformation within the DTL Editor Testing Tool (EnsPortal.Dialog.TestTransform.cls)? Is this something we can get in an Enhancement request in for?

It would save sometime in troubleshooting where an error might be in the DTL.

Just wondering...

Thanks

Hello,

I have a couple of IOT devices that communicate via WebSockets to our backend.

I successfully managed to create a websocket connection between server and (iot)client using %CSP.WebSocket
However I would like to implement authentication on this using the HTTP headers at the same time of Connection: Upgrade.

I tried to set the headers to globals in order to debug but they are always empty.

Example code:

InterSystems technologies are renowned for their high performing databases, which support the systems and operations of many organisations. However a key ingredient to this success is the quality and maintainability of their code.

The quality of code can impact everything from speed and ease of fixing bugs and making enhancements, to the overall performance of your organization and your ability to get ahead in the marketplace.

By ensuring your code is maintainable, you can reduce approximately 75% of the systems life cycle costs*. This is why, at George James Software, the solutions we build are always straightforward and written in high quality code - because we know that this solid foundation can positively impact the rest of your organization.

With a maintainable system you're able to reduce your overall maintenance as any issues that occur are significantly faster to identify and fix. This means you're free to allocate that time and budget to enhancements, enabling you to get the most value out of your applications and ultimately better support your organization.

Keep an eye out for our next few posts about what a maintainable system looks like and the tools that can help you keep your code maintainable, in order to help you to reduce those maintenance costs.

Can you please provide steps to debug in VS code using serenji and how to put break point in VS code, I have tried using F9 but it is not working.

I want to debug API code using postman.

Hi I am trying to run a debugger in VS Code. I have the settings.json file and the launch.json file. I am trying to debug code using the attach to a process method, however when I run the debugger I get the following error.

Launch.json code

{

// Use IntelliSense to learn about possible attributes.

We have a custom business service that is triggered by a scheduled task. The service queries a table, iterates over the result set and sends a message on to a business process for each result. Happy path functionality is all fine.

However, when there is an error detected in the business service code, neither throwing an exception nor returning an error %Status behaves as we'd expect.

Not everyone knows that InterSystems Caché has a built-in tool for code profiling called Caché Monitor.

Its main purpose (obviously) is the collection of statistics for programs running in Caché. It can provide statistics by program, as well as detailed Line-by-Line statistics for each program.

Using Caché Monitor

Let’s take a look at a potential use case for Caché Monitor and its key features. So, in order to start the profiler, you need to go to the terminal and switch to the namespace that you want to monitor, then launch the %SYS.MONLBL system routine:

Hi everyone,

I have an existing application on HealthShare 2015 and decide to move it to HealthShare 2018 to make use of Atelier support. I am using Eclipse Photon with Atelier Plugin 1.3.

Most of things are working better on Atelier comparing with Built-in studio of HealthShare. However, when I tried debugging CSP file with Atelier I encounter 2 problems:

1.

Every developer has made the mistake of accidentally leaving temporary debug code in place when they meant to remove it after debugging is complete. The great thing about writing in ObjectScript is that there is a way to make temporary code be truly temporary and automatically self-destruct! This can also be done in such a way that the code has no change of making it into your source control stream, which can be helpful as well.
