Collecting material for the next edition of my WebLogic 12c book I began writing a primer about Oracle Coherence from a WebLogic perspective. Coherence is part of the WebLogic Suite and you can start using it right away.

Many WebLogic professionals still consider Coherence as something complicated and challenging to get started with, so I made a number of hands-on Coherence primer screencasts available – also more blog postings with best practices will follow.
