Upgrading to Oracle Fusion Middleware 11g (11.1.1) / 11gR2 (11.1.2) Portal, Forms, Reports and Discoverer Services Memory Requirements (Doc ID 1086360.1)

Last updated on JUNE 01, 2023

Applies to:

Portal - Version to [Release FMW11g]
Oracle Fusion Middleware - Version to [Release Oracle11g]
Oracle Discoverer - Version to [Release 11g]
Oracle Reports Developer - Version to [Release 11g]
Oracle Forms - Version to [Release 11g]
Information in this document applies to any platform.


This document discusses the host machine memory requirements if upgrading OracleAS 10g Rel 2 Portal, Forms, Reports and/or Discoverer (PFRD) middle tier to Oracle Fusion Middleware 11g Rel 1 and Oracle Fusion Middleware 11g Rel 2 (11gR2) for Forms and Reports.

It is important to note that, unlike 11g Rel 1 which contains all PFRD components, the release 11g Rel 2 does NOT include Portal and Discoverer, it is an upgrade option only for Forms and Reports.

The advice is targeted at System Administrators / Architects who are intending to follow the Oracle Middleware 11g Upgrade Guide, and therefore use the 11g Upgrade Assistant to upgrade a source OracleAS 10g Rel 2 middle tier, which includes one or more of the PFRD (Portal, Forms, Reports and Discoverer) component set, to a destination Oracle Middleware 11g PFRD system instance and weblogic domain.


This document supplements the advice given in

Oracle Fusion Middleware System Requirements and Specifications 11g Release 1 (11.1.1) and 11g Release 2 (11.1.2) for Forms and Reports

It is not a replacement for these documents.

The Oracle Middleware 11g System Requirements and Specifications document referenced above, lists the memory requirements when Oracle Portal, Forms, Reports and Discoverer are all configured and used. The aim of this document is to highlight the difference in memory requirement between OracleAS 10g Rel 2 and Oracle Middleware 11g. It is important to recognize the difference so machine capacity is taken into account when planning an upgrade to Oracle Middleware 11g / 11g Rel 2. 

The article is intended for system administrators, architects, consultants and support engineers.
