The complexity of the Oracle Application Server infrastructure depends on the type of product installation. There are three Oracle Application Server installation types:
Each installation type builds on its predecessor's functionality; consequently, each requires a more complex infrastructure. 2.3.1 J2EE and Web CacheThe J2EE and Web Cache installation provides a high-performing and very scalable J2EE application server. In the Enterprise Edition version of the Oracle Application Server product, it consists of the following:
Note, however, that OracleAS Web Cache isn't included in the Java and Standard Editions. This installation requires a DCM repository in which Oracle Application Server configuration data can be stored. The repository for this version can be either file-based or stored in an Oracle database. 2.3.1.1 Portal and WirelessThe Portal and Wireless installation contains all the components of the J2EE and OracleAS Web Cache installation. It also contains:
Although this edition doesn't contain the following components, it uses them at runtime, so the infrastructure has to exist before you install this edition:
Note that OracleAS Portal and OracleAS Wireless store their own application data in the infrastructure's OracleAS Metadata Repository. 2.3.1.2 Business Intelligence and FormsThe Business Intelligence and Forms installation contains all the components available in the OracleAS Portal and OracleAS Wireless installation, as well as the following additional components:
This installation doesn't add any more complexity to the infrastructure because no additional infrastructure components are required, but it does add more metadata. Like the Portal and Wireless edition, the Business Intelligence and Forms edition uses a preexisting infrastructure. However, there is also a standalone installation for the Forms Server and Reports Server that doesn't require an infrastructure. |
