1 Planning Your Oracle Coherence Installation

This guide will help you install Oracle Coherence. Various topics are covered that should be reviewed thoroughly to help ensure that you do not encounter any problems either during or after the Oracle Coherence installation.

To install standalone Oracle Coherence, there is no prerequisite for Oracle Fusion Middleware Infrastructure. If you do have the Infrastructure on your system, then Oracle Coherence can be integrated with it in a number of ways. For the purposes of this guide, only the standalone mode is considered.

Note:

Oracle Coherence can also be installed as part of an Oracle WebLogic Server installation. Installing and configuring Oracle Coherence with WebLogic Server is beyond the scope of this documentation. See Planning the Oracle WebLogic Server Installation in Installing and Configuring Oracle WebLogic Server and Coherence.

This chapter contains the following sections:

1.1 About Oracle Coherence

Oracle Coherence in-memory data grid is a key component of Oracle's Cloud Application Foundation. Oracle Coherence predictably scales applications to meet mobile and cloud demands on shared services and infrastructure.

  • Provides real-time application processing using parallel query, live event processing, map-reduce aggregation, and parallel transaction processing

  • Scales applications linearly and dynamically for predictable cost and reliable delivery of real-time customer experiences

  • Enables continuous data availability and transactional integrity across the most demanding multi-data center deployments

  • Oracle Coherence's GoldenGate HotCache enables businesses to leverage real-time cache updates to provide always-accurate application information

  • Provides operational simplicity through advanced integration with Oracle WebLogic Server, across conventional and cloud environments, and Oracle Exalogic Elastic Cloud

1.2 Introducing the Oracle Coherence Standard Installation Topologies

Using Oracle Coherence software together with other application software, you can create a variety of production topologies to suit the needs of your applications, your organization, and your application users.

As a result, it is difficult to provide exact instructions for every possible Oracle Coherence installation. This documentation provides detailed instructions for installing Oracle Coherence only in standalone mode.

For more information about standard installation topologies, see Understanding the Standard Installation Topology in Planning an Installation of Oracle Fusion Middleware.
