Caché service does not start

Help, after a day of coding, I wanted to backup my files. I found out that alle of my 3 instances of caché refuse to start.

the error says: cstart-exe-fout (112 Service for Caché instance did not start).

Is there a way to solve this? (off course the management portal does not work either.)

I think there has been a power interruption as the battery from my laptop does not work, and the power went off before

shutdown.

Thanks in advance!

I'm trying to set up VS Code for ObjectScript using the instructions found here. I've got both Cache 2018.1.2.309.0 and IRIS 2020.1.0.215.0. When I try to connect to either one of them the connection fails, and I get a notification in the bottom right corner that says "Unexpected token < in JSON at position 0". I've checked the JSON settings file that VS Code uses, and they're fine and formatted properly. All of the settings I've entered are correct.

Hi all,

This might be a stupid question, but I'm going to ask it anyway.

My goal is to write a scss file, pack it as part of a local library (Something like my_library.tgz), npm install that library into a different project and then import that scss file in one of the scss files in the new project.

Simply having the scss file exist in the library before I pack it didn't seem to work; the file wasn't under node modules after the npm install. Am I doing something wrong, or are there extra steps I have to take?

Thanks in advance.

In this article I would like to present the RESTForms project - generic REST API backend for modern web applications.

The idea behind the project is simple -after I wrote several REST APIs I realized that generally, REST API consists of two parts:

  • Work with persistent classes
  • Custom business logic

And, while you'll have to write your own custom business logic, RESTForms provides all things related to working with persistent classes right out of the box.
Use cases

  • You already have a data model in Caché and you want to expose some (or all) of the information in a form of REST API
  • You are developing a new Caché application and you want to provide a REST API

I have 2 instances of Cache, one of 2010 and the other 2016. On both I have created a SSL Configuration with same name.

When I connect to a SOAP Service Client from Cache 2010, I get the above error.

If I connect from Cache 2016, the connection get through.

How can get more details of the error in the Cache 2010 instance to be able to fix this issue.

I have enabled the SOAP Log and it does not give much of details.

Regards

Anil

While this article is about InterSystems IRIS, it also applies to Caché, Ensemble, and HealthShare distributions.

Introduction

Memory is managed in pages. The default page size is 4KB on Linux systems. Red Hat Enterprise Linux 6, SUSE Linux Enterprise Server 11, and Oracle Linux 6 introduced a method to provide an increased page size in 2MB or 1GB sizes depending on system configuration know as HugePages.

At first HugePages required to be assigned at boot time, and if not managed or calculated appropriately could result in wasted resources. As a result various Linux distributions introduced Transparent HugePages with the 2.6.38 kernel as enabled by default. This was meant as a means to automate creating, managing, and using HugePages. Prior kernel versions may have this feature as well however may not be marked as [always] and potentially set to [madvise].

Transparent Huge Pages (THP) is a Linux memory management system that reduces the overhead of Translation Lookaside Buffer (TLB) lookups on machines with large amounts of memory by using larger memory pages. However in current Linux releases THP can only map individual process heap and stack space.

So, one day you're working away at WidgetsDirect, the leading supplier of widget and widget accessories, when your boss asks you to develop the new customer facing portal to allow the client base to access the next generation of Widgets..... and he wants you to use Angular 1.x to read into the department's Caché server.

There's only one problem: You've never used Angular, and don't know how to make it talk to Caché.

This guide is going to walk through the process of setting up a full Angular stack which communicates with a Caché backend using JSON over REST.

Docker-compose default network conflicts

I recently had to diagnose a networking problem I was having when attached to our corporate network. I was seeing an unknown bridge network being defined that shared the same IP address space as the company network thus blocking access to company resources. This bridge network was separate from the Docker0 bridge network which the docker engine sets up. Docker was configured with a bip (bridge ip) address to prevent docker form using an address space that create a conflict.

Hi,

Is it possible to Save a base64 data string, representing a png, as a binary png file, In Cache?

When I search google , in general , not Cache specifically, I see such articles:

https://stackoverflow.com/questions/11511511/how-to-save-a-png-image-ser...

and this answer:

You need to extract the base64 image data from that string, decode it and then you can save it to disk, you don't need GD since it already is a png.

This week I am going to look at CPU, one of the primary hardware food groups :) A customer asked me to advise on the following scenario; Their production servers are approaching end of life and its time for a hardware refresh. They are also thinking of consolidating servers by virtualising and want to right-size capacity either bare-metal or virtualized. Today we will look at CPU, in later posts I will explain the approach for right-sizing other key food groups - memory and IO.

So the questions are:

Hi

I have an Ensemble Application with many classes and relationships between those classes.

I need a tool that can connect to Cache/Ensemble and create a visual ERD from the class definitions within a particular Cache Namespace

MS-Access is one option but it does not automatically create the relationship connectors between classes

Any suggestions

Hello guys,

I've got this piece of code which runs the method "WebMethod", that belongs to %SOAP.WebBase.cls.

It grabs the outcome from an internal webservice we have and after that, it writes into a file.

The thing is, when I browse the file contents, I realize that in the place where a special character should be, I see a question mark.

By querying the same webservice from a special soap tool called "SoapSonar" (I've been using this for years), the outcome shows up this special character (shows it properly).

Anyone using Visual Studio Code?

Is anyone in the fine community of developers who work with ISC technologies looking at Microsoft's Visual Studio Code offering?

One of Bill McCormick's recent posts about Atelier referred to Visual Studio being considered the best IDE. Granted, Code is far less of a tool than VS, and probably always will be. But it claims to be open source and cross-platform, i.e. Linux and OS X as well as Windows.

Developing a Full-Stack JavaScript web app with Caché requires you to bring together the right building blocks. Previously, I outlined the basic steps to install and connect Node.js to Caché and make it's powerful multi-model database capabilites available for use with Node.js. You can use Caché as a NoSQL-, document- (with unique key-level access!), SQL- and object-database with Node.js. When developing JavaScript applications, you'll see how powerful this combination is and makes Caché a perfect fit for Node.js.

In the first part of this article series I will show how to get started with the React framework, one of the most popular frameworks currently taking over front-end development. In the next parts you'll learn how to connect a basic web app to a Caché back-end.

You'll see, it's very easy to get started with this technology - you can even compare the amount of basic knowledge you need to COS because you only need to know a few basic concepts to start!

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)

Configuring an Ensemble production can be a challenging task involving a thorough understanding of the system and production functionality and a detailed understanding towards each configuration item. After successfully configured an Ensemble production, you might need to set up an identical production on the mirror environment, or deploy the production on a development system to a live system, or send a copy for diagnostic/debug purposes. Other times you might have spent some time designing a BPL/DTL and some other productions can use the same logic.
