When we talk about distributed data grids, elastic caching platforms and in-memory caching technologies, Oracle Coherence is the first option that came in our minds. This happens because Oracle Coherence is the oldest and most mature implementation of data grids, creating successful histories across the world. It is Oracle Coherence the implementation with the bigger number of use cases in the world. Since it's aquisition by Oracle in 2007, the product has been enhanced with powerful enterprise features to remain it's position of the "better of the world" against it's competitors.
This article will help you given your first steps with Oracle Coherence. I have prepared a sequence of three videos that will guide you in the process of creating a data grid cluster, managing data using both Java API and CohQL ("Coherence Query Language") to finally test the reliability and fail over features of the product.
Oracle allows you to download and use any of your products for free, if you are interested in learning or testing the technology. Different of other vendors that put you first in contact with a sales representative or simply not put their software available for download, Oracle encourages you to use the technology so you gain confidence with it. You can download Oracle Coherence at this link. If you don't possess a credential in the OTN ("Oracle Technology Network"), you will be asked to create one.
If you have a powerful computer and a fastest internet bandwidth, change the video quality settings to 1080p HD ("High Definition"). It will improve considerably the quality of your viewing.
