Optimizing EhCache configuration for WebCenter Sites

In this blog article I would like to share my ideas and strategies that I have used on how to configure WebCenter Sites’ page, pagelet and inCache. I will discuss several trade-offs in configuring the cache. I would not go into detail on ticket caching for CAS.
This blog expects that you have a good understanding of WebCenter Sites’ and its caches. It also focussed on Delivery server cache tuning. For Editorial servers the Asset Cache and resultset cache are much more important than pagelet cache.

User Engagement – Why Does it Matter?

The value of any system can be measured by how often you interact with it. The perfect example is Slack, which is now seen as the most successful collaboration app ever and is valued at $1.2bn. The key metric for this is DAU/MAU (the ratio of daily users over monthly users), which scales from 0 (no visits) to 1 (every user visits daily) based on how active your users are.

JEE : Using EJB and Context annotations in a JAX-RS Provider class

A lot of new annotations have been introduced since the JEE6 spec. Before we had EJBs and servlets to cover most of our server-side objects in a JEE application. But in JEE6, CDI and JAX-RS have been added, along with a few other JSRs that are implemented using annotations. This results in a long list of annotations, where – in my opinion – it is not always clear which one to use, nor to understand how they work together.

In this blog, I would like to show you how EJB and CDI work or don’t work together, in combination with a JAX-RS Resource.

EPM workspace integration with OBIEE 11.1.1.9

It wasn't so long ago I wrote a post about integrating EPM 11.1.2.3 workspace with OBIEE 11.1.1.7, now with the recent release of OBIEE 11.1.1.9 I have to keep up the tradition and test out if the integration is still working, if I don’t then I will just get asked the question so I thought I would get there before it gets asked.

Once again I am not going to go into too much detail because I have covered it all before and you can read about it in the following blogs:

5 Minute JavaScript #18: reduce
