Oracle Collaboration Suite is an integrated, standards-based collaboration solution. It has a multitier architecture and is built on proven Oracle technology, Oracle9i Database and Oracle9i Application Server.
In the current business scenario, the availability of the collaboration system directly affects business processes, user productivity, and cost. Oracle Collaboration Suite consists of different components deployed on multiple tiers. The availability of each component has a direct impact on the availability of the system.
Besides providing high-availability features, Oracle Collaboration Suite must also be secure. This would ensure that both Internet and intranet users can use the system without compromising availability and security.
This chapter provides an overview of the following components of Oracle Collaboration Suite:
Section 1.1, "Infrastructure Database and Oracle Internet Directory"
Section 1.2, "Oracle9iAS Single Sign-On and Oracle Delegated Administration Services"
Section 1.3, "Oracle Calendar Server and Oracle Files Domain Controller"
Oracle Collaboration Suite Release 2 (9.0.4) Infrastructure is based on Oracle9i Application Server Release 2 (9.0.2). The Infrastructure consists of the Metadata Repository, an HTTP Server, and the OC4J_DAS instance. The Metadata Repository is based on Oracle9i Database release 9.0.1.4, and it stores Oracle Internet Directory information and Oracle9iAS Single Sign-On metadata.
The Infrastructure database and Oracle Internet Directory components are based on Oracle9i Application Server Infrastructure. Typically, these components are deployed behind a firewall on the intranet. In the deployment architecture described in this document, the Infrastructure is deployed on two tiers. The Infrastructure database and Oracle Internet Directory components are deployed on one tier. The Oracle9i Application Server Single Sign-On and Oracle Delegated Administration Services components, which are covered in the next section, are deployed on two or more servers on a single tier in the demilitarized zone (DMZ).
To secure the Infrastructure, the Middle Tier provides Oracle9iAS Single Sign-On and Oracle Delegated Administration Services to the application components. Together, the Oracle9iAS Single Sign-On and Oracle Delegated Administration Services components and the Infrastructure database and Oracle Internet Directory components provide the Oracle Identity Management service.
The Oracle Calendar Server and Oracle Files Domain Controller components are not deployed on the Middle Tier. They are deployed on a separate tier behind a firewall on the intranet. Oracle Calendar Server includes the file system level database that stores all calendar-related data. This database is not the Oracle Database, and it does not provide the same high-availability features.
The Oracle Calendar Server (one server per calendar node ID) and Oracle Files Domain Controller components are placed on a cold failover cluster because they are single processes. Alternatively, the Oracle Files Domain Controller can remain on the Middle Tier with proper monitoring and restart capabilities.
Information Storage is based on Oracle9i Database Release 2 (9.2). It is the data store for Oracle Collaboration Suite components and is deployed behind a firewall on the intranet.
