Preventing Forms 11g Memory Jump after RUN_REPORT_OBJECT by Using a JVMCONTROLLER (JVM Pooling) (Doc ID 1277681.1)

Last updated on SEPTEMBER 12, 2016

Applies to:

Oracle Reports Developer - Version 11.1.1.1.0 and later
Oracle Forms - Version 11.1.1.1.0 and later
Information in this document applies to any platform.
Applies to Forms and Reports 11g


Goal

In 10g, the JVM pooling feature could only be used by the Java Importer. For this reason, methods such as the one mentioned in <NOTE 266073.1> were needed to reduce memory usage when using RUN_REPORT_OBJECT (RRO). However, in 11g, with JVM pooling enabled, Oracle Forms Services uses a shared JVM controller for Oracle Reports requests resulting in less overall memory usage. Here is a method for configuring a jvmcontroller to start when a form using RRO is called via a specific formsweb.cfg configuration section.
