Welcome @stoeps.de, the blog of Christoph Stoettner
I work at Vegard IT GmbH as a senior consultant with a focus on collaboration software, Kubernetes, security and automation. I mainly deal with HCL Connections, WebSphere Application Server, Kubernetes, Ansible, Terraform and Linux.
Sometimes my daily work results in technical talks and blog articles, which you can follow here more or less regularly. You can find the presentations in the main menu under public speaking .
I created a list of tools I use regularly, most of which have been released under an open source license.
In my spare time I read a lot, test all kinds of technical software and gadgets and try to follow about 200 RSS feeds.
Here you can find a collection of them.
This is my private blog, all opinions are my own.

I started reviewing old blog post and replace links, or check if the information is still valid. So here are the last updated articles.

Elasticsearch in HCL Connections Componentpack is secured with Searchguard and needs certificates to work properly. These certificates are generated by bootstrap during the initial container deployment with helm.
These certificates are valid for 10 years (chain_ca.pem) or 2 years (elasticsearch*.pem) and stored in the Kubernetes secrets elasticsearch-secret, elasticsearch-7-secret. So when your HCL Connections deployment is running for 2 years, the certficates stop working.
Last week I played around with the HCL Connections documentation to backup Elasticsearch in the article Backup Elasticsearch Indices in Component Pack .
In the end I found that I couldn’t get the snapshot restored and that I have to run a command outside of my Kubernetes cluster to get a snapshot on a daily basis. That’s not what I want.
During a migration from Cognos Metrics to Elasticsearch Metrics, I had some issues with the index. So I wanted to create a backup of the already migrated data and start over from scratch.
The official documentation has an article on the topic: Backing up and restoring data for Elasticsearch-based components , but I had to slightly adjust the commands to get a successful snapshot.

In the last few years, I have had issues with application servers using a large amount of CPU and even hanging application servers running the Tiny Spellchecking service. It ended with disabled spellchecking in the Tiny Editors’ config.js.

I created a git repository with some smaller CSS files to fix some annoyances within HCL Connections.
I started with this to prevent Orient Me to load fonts from external URLs or Elasticsearch Metrics to break the UI on larger screens. These issues are solved after the last updates I got from support, but Blogs and Tailored Experience Wizard can be improved with some simple rules.
The annual conference of DNUG took place in Constance from 22nd to 23rd of June 2022.
I attended the HCL Connections Roadmap session given by Rene Schimmer and David Strachan. They showed the updates for version 8 and beyond.
