Applies to Forms and Reports 11g
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.
