This graphic shows an Oracle BI Publisher single instance architecture. A silver cloud represents the Network. Requests from the network crosses a firewall to WEBHOST1, which contains a box labeled CHS. Data passes through another firewall into a box labeled APPHOST1 in the application tier.

The APPHOST1 box contains two boxes, WLS_BIPI and WebLogic Server/Admin Server. WLS_BIPI contains BI Publisher. An arrow from BI Publisher points to a disc labeled Scheduled Jobs Information among a cluster of discs called the Oracle RAC Database in the Data Tier.

Two arrows point out of WLS_BIPI. One passes through a box labeled Data Sources before crossing the firewall into the Data Tier and ending at a cluster of discs designated Oracle RAC Database. The other arrow points at a Repository box in the Data Tier.

The Repository Box in the Data Tier contains a box for BI Publisher Configuration Folder and another box for BI Publisher Reports, Definitions, and Layouts.
