To configure a PostgreSQL data source in WebSphere, you need to complete a few steps:

1. Install the PostgreSQL JDBC driver library in the appropriate WebSphere directory.
2. Configure JAAS authentication aliases for the data source.
3. Define a JDBC provider for PostgreSQL.
4. Create a JDBC data source that will be used by applications running on the WebSphere server.
5. Set connection parameters, such as the database name, server address, and port number.
6. Configure additional connection pool parameters, such as the connection age limit.
7. Apply the changes and start the WebSphere server.
8. Test the connection to the PostgreSQL database to make sure everything is working properly.

Recently I have become a fan of Docusaurus and I have started using it to create my blog and other websites that I own. In one of the posts I described how to integrate Docusaurus with YouTube, and now it is time for integration with Disqus. Integration with Disqus allows readers of my blog to comment on entries, allows them to share their opinions about them, which is very important to me. Every opinion affects the development of the blog and also my knowledge.

On the first page of Docusaurus there is a frame with a YouTube video. How to do it? In this post I will describe how to integrate Docusaurus with YouTube, because as it turns out, it is not that difficult, but to achieve all the functionalities, such as displaying the video in full screen, we have to follow the rules, which do not seem obvious at all. I spent a few hours on it before I managed to achieve the expected effect, so I decided to share this knowledge with others.

IBM® Business Automation Workflow is a platform that enables you to create workflow applications to increase productivity.

In this article, we will present a step-by-step installation of IBM® BAW version 21.0.3. For the installation, we will use the Rocky Linux 9.5 operating system. It is important that if we use a free distribution of the operating system, it should be from the RedHat family. So far, I have performed the installation on CentOS 8, but after it was withdrawn from the market, I decided to test Rocky Linux.

We have a performance problem with a Java application installed on IBM WebSphere. What should we do? First of all, data collected in so-called dump files is useful in the analysis.

Recently I encountered a problem of excessive user session expiration in IBM BPM version 8.6.1.19003 in Chrome and Edge web browsers. The problem was particularly troublesome when Human Service was launched in an iframe and SSO SPNEGO was configured. Downloading the content (form) of the service ended with an error message: IBM Business Automation Workflow could not download data from the WWW session. It may have expired.

It may happen that after logging in ssh -X we will get the message:

Last login: Thu Mar 24 21:41:30 2016 from 10.99.0.2
/usr/bin/xauth:  timeout in locking authority file /opt/ibpmusers/scichy/.Xauthority

And setting the DISPLAY environment variable correctly doesn't work for us.

To run a desktop application with a graphical interface on a server connected via the SSH console, you need to add the -Y or -X argument to the ssh command (see ssh man).
