 Report Transformation. BI Publisher transforms the data XML stream and the format

template into a desired output document. This document may be HTML, XML, PDF, RTF, or an

Excel spreadsheet.

 Distribution. For ad-hoc reports, the user may request the report be served directly back to

their browser. Alternatively, they may want the report to an e-mail recipient via SMTP.

Scheduled reports are either sent directly via e-mail or transferred to an Oracle Transportation

Management Contact. This leverages the Notification subsystem to notify interested parties of

the report via e-mail, fax or message center

, attaching or linking to the report contents.

These components typically use significant CPU and memory resources. By default, they are run on an

application server to:

 perform all data queries behind a firewall;

 avoid degradation of web server response;

 manage SMTP backup through the Oracle Transportation Management event queues;

 avoid disk storage of reports on an open web server; and

 scale report generation via application-tier scalability

There may be cases, though, where one or more of these components should run in the web-tier. For

example, very large reports are more efficiently generated on the requesting web server. RMI, the

transport protocol between the web servers and application servers, defaults to a maximum 10 MB

message size. Trying to generate such reports on an application server may require larger RMI buffers

with a subsequent impact on application-tier and web-tier memory to support the data transfer.

The following table lists properties which control report architecture:
