Oracle Coherence Initial Setup

It is very easy to get started with Oracle Coherence and run your first local cluster. However, the real learning curve is steep, especially configuring and planning your real cluster. Documentation is extensive but doesn't give you a good learning path.

Initial setup is not exactly easy. At first, it is a little complicated. Once you do it, and stabilize the solution, it is good. People who are know these kinds of things can do it.

We use Coherence for a number of applications, each with different requirements. It’s hard to provide a simple answer regarding initial setup but, in general, we find that Coherence is relatively simple to set up and use. However, it quickly becomes very complex as more features are used.

OSB can be tuned a little bit better.

It was complex and hard to understand the hidden capabilities. Documentation requires more crispy detail rather than lengthy.

Very easy. The XML config files were clear how to configure.

Initial setup is somehow complex, as you have to configure the hosts that will hold the Coherence nodes, every cache that you set up and all of the domain classes to be used for serialization.

For development work, I usually run Coherence on the development server which has more memory capacity.

Architecture Manager at a leisure / travel company with 1,001-5,000 employees

Initial setup was complex because we integrated GAR files in EAR files. We were one of the first customers who were building the cluster, along with the business logic, and deploying everything together in a single operation. We got a complete step-by-step to cover our needs from the post-sales engineering team.

Coherence is very easy to get running locally. Standing up, or defining a cluster for that matter is another task entirely. Each cluster has many ‘knobs’ to dial in. While this offers great flexibility, one should exercise caution when getting into areas of the config that are not understood.

The objective of the project and the performance need to be kept in sight. Here are some questions to help drive the configurations files: Is your project read or write heavy? This will dictate if you should have more smaller nodes vs less larger ones. Should they be storage enabled or not? How much data does the app generally use, would a near cache be beneficial? How often is your reference data used, how much is there determines if it should replicated or not. How many members should there be? Do I need to use a prime number somewhere? Why? Do I need eviction policies, what should they be based on? How do I tell if my cluster is too chatty? How will other apps leverage the cluster? Should I use WKA? Will that prevent new members from joining?

It goes on and on and we didn’t touch DR or monitoring.

The initial setup was neither complex nor really easy. It was somewhere in the middle. I didn't really involve myself in that directly. I am one of the heads of the site. I just fed them the data. It was pretty much implemented by mid-level people; so I don’t really know what the challenges were.

Initial setup was complex, until we contracted an expert who helped us to configure everything. After that, life was easier. ;)

While Coherence was already deployed on premises, integrating it into a new application was cumbersome.

The latest version is straightforward, as there is lots of configuration done through the WebLogic console.

The tutorials helped, but I use NetBeans, so there was a learning curve, but nothing complicated.

Installation was rather straightforward and usage was simple. But the complex part was mainly using PofSerializer, which did not work that easily for me and we ended up using a standard Java serialiser in the end.

Initial setup was complex. We wrote a lot of wrapper code around the Coherence libraries in order to make it easier for the developer.

Initial setup is bit complex in WebLogic 12c when compared to WebLogic 10g. Performance is very good in Coherence.

It is very easy to set up a basic topology, but hard to configure and tune to make it really work.

It was complex. There are a multitude of configuration files and shell scripts, most of which could be copy and pasted. No uniformity of approach or tool to allow for proper management of configuration.
