Symptoms

There can be times when design of one or several Portal page(s) is complex and it contains several portlets : web provider portlets, page portlets, database provider portlets, etc.

When this design complexity is extremely high there might be problems associated, ie, the Page Parallel Engine (PPE) may need to be tuned in order to cope with the large number of portlets available on the Portal pages.

In the above situation the following can be noticed:

1. While adding a new portlet to a page which is already complex other portlets in other regions may disappear.

2. While rendering the complex Portal page the following errors can be seen in the application.log file from the Portal OC4J:
