Figure 1-2 Figure 1-2 Oracle Thesaurus Management System Network Topology

Table 1-2 shows how the Oracle Thesaurus Management System components and technology stack are related and provides an example of how the product can be installed. The left side of the Application Tier—APPHOST1—is a standard installation, while the whole—with APPHOST2—shows a multi-node middle tier installation using Oracle Clusterware.

In the client tier, end users' browsers communicate via HTTPS with the Oracle HTTP Server (OHS), which is located inside a firewall. When users log in, OHS detects the product they logged in to and consults formsweb.cfg to connect them to the appropriate application tier service.

The application tier comprises Oracle Application Server and Oracle WebLogic Server. The integrated tier has two domains:

• FRDomain includes the Oracle Forms runtime service and Forms Server, and the Oracle Reports Server and engine, which run Oracle Thesaurus Management System forms and reports. It also includes the WebLogic Server Admin Server and Oracle Enterprise Manager.

  The Oracle Application Server domain must be named FRDomain and it is recommended to use port number 7001.

• OPADomain includes the WebLogic Server Administration Console, WebLogic Server Java, and Managed Server of OPADomain, which are required to run the TMS Lite Browser and TMS reports. It also contains the database connections.

  The TMS Installer automatically creates the OPADomain. It is recommended that OPADomain uses port number 7101.

  You can distribute the application tier over multiple nodes in a network using Oracle Clusterware. The Admin Server is required only on the primary node.

  In TMS, there are two node managers: one for FRDomain and the other for OPADomain. The Installer will configure the OPADomain Node Manager. The FRDomain Node Manager is configured during the technology stack installation.

  The database tier includes Oracle Database with Oracle Thesaurus Management System. The diagram shows a distributed installation integrated with Oracle Clinical using Oracle Real Application Clusters (RAC); this is one example of how it can be installed.
