We are excited to announce that Coherence 14.1.1 was released overnight!
Coherence 14.1.1 contains the following major new functionality:
- Topics – a messaging implementation with patented scalability;
- Distributed Tracing – cross-process call trees captured using the OpenTracing API;
- GraalVM support – enabling polyglot programming on the grid side; and
- JDK 11 certification throughout the release’s lifecycle.
For full information on the release, please see the official Coherence Blog entry at https://blogs.oracle.com/oraclecoherence/oracle-coherence-1411-released.
You can also view videos explaining the new features on the Coherence YouTube Channel – https://www.youtube.com/playlist?list=PLxqhEJ4CA3Js7xPLXSgrO0nlu4Ab4vNSS
With the release of the Coherence Operator, which allows customers to run Coherence within a Kubernetes environment and the recent Coherence 188.8.131.52 release, you now have the ability to expose Coherence metrics in a Prometheus format and therefore monitor your Coherence cluster via Grafana!
When deploying Coherence using the Coherence Operator, Grafana and Prometheus can be directly provisioned as part of the Coherence Operator helm install, or you can scrape Coherence metrics using your own Prometheus and push to your own Grafana.
The good news for those of you who are running Coherence 184.108.40.206+ but not within a Kubernetes environment, is you can still take advantage of this new integration!
I have created a step by step guide at my GitHub page below of how to achieve this – https://github.com/tmiddlet2666/coherence-grafana-metrics
At a high level, you need the following:
- Docker Desktop for Mac or the equivalent Docker environment for you O/S
- Coherence 220.127.116.11
- JDK8 or 11
- Maven 3.5.4+
If you follow the steps, you will be able to monitor your Coherence cluster via the rich set of Grafana dashboards we have made available.
For more information on the dashboards, please see https://oracle.github.io/coherence-operator/docs/2.1.0/#/metrics/050_dashboards!
Oracle “Coherence Cloud Edition BYOL” (Bring Your Own License) is now available on the Oracle Cloud Marketplace in all regions.
This release contains the options to install either Coherence version 18.104.22.168.1 or 22.214.171.124.5 and allows you to get up a running quickly with the latest Coherence releases. Once provisioned, you can easily change/modify the cluster to suit you needs.

Have a happy and safe festive season and see you next year!

We are excited to announce that version 2.0.0 of the Coherence Operator is now GA!
Version 2.0.0 introduces a Kubernetes Custom Resource Definition (CRD) for Coherence clusters which simplifies the definition, deployment and management of Coherence applications within a Kubernetes environment.
Some useful links:
The Coherence Demo application has now been updated to work with Coherence 188.8.131.52.0 and the new Coherence Operator 2.0.0. This can be found on GitHub.
See the Official Coherence Blog for the announcement.
Over the weekend Coherence 184.108.40.206.0 was released! Below are some of the new features. See the Release Notes for the full list of new features.
Docker and Kubernetes Support
Oracle Coherence is certified to run in Docker containers and can be orchestrated using the Coherence Kubernetes operator. For more information see here.
Coherence supports management operations using REST. This includes exposing the Coherence MBeans over REST, Allowing the JVisualVM Plugin to connect to a Management over REST endpoint and a comprehensive Swagger API listing.
See here for more information.
An endpoint that can be scraped to provide metrics related to the local node. The format of the returned text is compatible with Prometheus. See Using Coherence Metrics for more information.
A replacement to replicated caches that combines ContinuousQueryCaches and distributed caches to provide the same read performance but consistently processed writes. See the View Scheme.
For a full set of new features, please see the Release Notes for 220.127.116.11.
Now that the Coherence Operator 1.0.0 is released, the Coherence Demo has been updated to run on Kubernetes using the Coherence Operator.
