Announcing Coherence

Guest Author

Oracle Coherence is here!  That's a lot of numbers.  Or three, depending on how you count.  What it really means is that this release is a patch-set and not a large new release.  The release is packed full of goodies for users of the new Federated Caching and Persistence features released in October 2015 as part of Coherence 12.2.1, and also contains many improvements for users of any prior Coherence release.

Here is a summary of the changes.  For a full description of the changes in, check our release notes.  

Federated Caching Improvements 

Coherence Session API

  • The Coherence Session API provides applications with a new and recommended interface to get a reference to a NamedCache instance. 

Proxy Tier Management Information

  • New Proxy Tier Management Information includes the number of connections across each proxy server and the total
    messages that were sent and received. Management attributes are included on the
    ConnectionManagerMBean and are viewable on the Proxy HTTP Report and the
    HTTP Servers tab in the Coherence-JVisualVM Plug-in.
