thanks a lot. <br />

Doug,

<div>
this is a good insight into the problem.

I have a Rest Based Java application which creates and gets data from SAP Gateway for sales order. The Order in SAP keeps updating with status of order such as dispatch/closed/canceled from messages. <br />
<br />
The application is expected to be slow. Introducing coherence in java to SAP layer is expected to improve the performance but there is a risk that the data in coherence layer will be stale and so order data on UI will be old due to cached data.<br />
<br />
How can we handle coherence cached order detail data which is getting updated from 2 sources?<br />
<br />
Should we upgrade to SAP Hana (which is not popular or yet stabilized) in comparison to Coherence/Giga Spaces/Data Grid. Which is the best caching mechanism and how to handle &nbsp;stale data.

Can Coherence update cache from 2 sources and how it works

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.

Java

An application server is a software framework that provides both facilities to create applications and a server environment to run them. Most application server frameworks contain a comprehensive service layer model, acting as a set of components accessible to the software developer through an API defined by the platform itself. For Web applications, these components are usually performed in the same running environment as their web server(s), and their main job is to support the construction of dynamic pages. However, many application servers target much more than just Web page generation: they implement services like clustering, fail-over, and load-balancing.
