Oracle Coherence can be used to solve latency problems by caching data near the application tier. In-memory performance helps to reduce data contention, thus improving application response time. Oracle Coherence does a great job at scaling linearly and can do so dynamically. Oracle Coherence can replicate data so it can be part of a disaster recovery solution. One thing that is often overlooked with elastic caches is their ability to analyze data in memory, leveraging the processing power of the data grid. This is something Oracle Coherence does exceptionally well. Oracle Coherence also provided event handling capabilities to allow applications to respond to events triggered by transactions.
User interface is easy to use, and in some ways better than Toad. The left hand side shows all databases, and you can drill down to instance, storage, schemas, tablespaces, and performance views. The right hand side displays the details of the selected object.
This is the best tool if you want to manage multiple RDBMS platforms in a single tool using the same familiar interface. Other third party tools can do it also, but it's not nearly as integrated as this, and may require additional plug-ins installed. DBArtisan excels at this, and can perform cross-platform data migrations easily.
It has different DB analysts, which can help diagnose issues with performance, optimize storage, detect fragmentation, and plan for capacity growth. For almost any action you want to take, you can generate the DDL for preview, and/or schedule it to run at a specific time.
Oracle Coherence support team is responsive and knowledgeable. We contacted them to ask a couple of design questions about how we were setting up Oracle Coherence based on how we used IBM's Datapower Extreme Scale. They were able to guide us so that we got the design correct the first time and didn't have to go back and re-architect our design later.
DataSynapse GridServer has the same cache functionality connected with a grid distributed application deployment platform. It provides all the necessary tools to configure and manage these applications. On the otherhand Oracle Coherence has more a flexible configuration and better performance. Also the Oracle configuration and monitoring tools are more convenient and informative than the DataSynapse ones.
It has a positive ROI on our organization. It's better than OEM and SQL Developer. Although the license could be expensive, it is perfect for large organizations, especially with multiple RDBMS platforms.
Most features are redundant between DBArtisan and Toad. I would not recommend using both if you already own one of them. Just download the trial for the one you're not using, and see what works best for your organization.
DBArtisan is great for DBAs and would be my personal preference. Toad is good for developers and DBAs alike but I feel like sometimes the interface is too busy and too clumsy to use.
In my current project, it is yet to be decided as we are on the way to make it live for users. But I am sure it will be an added value to obtain timely calculations.
