Distributing FME Server Components
You can physically distribute the components of an FME Server installation to achieve an n-tier architecture. Both 3-tier and 2-tier configurations are supported:
A 3-tier architecture distributes the FME Server Web Services, FME Server application (including the FME Server Core and FME Engines), and the FME Server Database across three physically separate servers. In this scenario, you must provide and manage the following additional components:
- A web application server to run the FME Server Web Services. You can run the FME Server Web Services on your own servlet (Apache Tomcat and Oracle WebLogic are supported), or use an Apache Tomcat servlet provided with the installation.
- A database server to host the FME Server Database (Oracle, PostgreSQL, and SQL Server are supported).
- A remote file system to host the FME Server System Share, which includes Repositories and Resources.
In a 2-tier architecture, an Apache Tomcat servlet is provided to run the FME Server Web Services, and is installed along with the FME Server Core and Engines. Only the FME Server Database is installed separately, on a server you provide, along with a remote file system.
Benefits of Distributing Components
Distribute components if you want to keep them separate so that each can be managed by the appropriate expert team.
Implementing a Distributed Architecture
You can implement a distributed architecture of FME Server in one of two ways:
- At installation time, by choosing:
- After an Express installation, by performing the following reconfigurations, where necessary:
