Using Oracle Coherence

Oracle Coherence is a distributed data grid solution, keeping data available in memory, and using sophisticated distribution algorithms and protocols to synchronize and transfer information between its nodes. This model gives us amazing access times by having data readily available and improved reliability by distributing the data between several instances and machines, adding redundancy to avoid loss of information.

The most recent version of WebLogic, 12.1.2, comes with the newest Coherence version, also numbered 12.1.2, and tighter integration between the two products; Coherence is now enabled by default at the server's classpath, working as a regular subsystem like JMS, for instance.

Note

If you are familiar with previous versions of WebLogic Server using Coherence, the concept of a Coherence Server has been dropped, and now what we have is a regular WebLogic Managed Server with Coherence enabled in it. This makes management simpler, normalizing the server concept...
