Interactive Reporting Web Client users can work with different versions of Reporting and Analysis on the same client machine. To enable this feature, new Interactive Reporting Web Client installations include multiple versions of the application. Users can work with all servers older than Release 8.3 + server through Release 8.5. The feature was added because the Reporting and Analysis installation does not have a backward compatibility mechanism and only supports the 8.5 version of the Interactive Reporting Web Client. The correct version that gets used is determined at run-time when theInteractive Reporting document (BQY) is opened. For example, if a user opens n Interactive Reportingdocument (BQY) in a Release 8.3 server, the 8.3 version of the Interactive Reporting Web Client is launched to serve the request.
Two Interactive Reporting Web Client versions are installed in this release: an 8.3 version and the current 8.5 release. Each Interactive Reporting Web Client plug-in entity is separated on the disk and in the registry. Each version is installed in a separate folder under <IE Install Directory>\PLUGINS\Hyperion\<Insight Series Version> or under <Firefox Install Directory>\Plugins\Hyperion\<Insight Series Version>. A mechanism has been implemented to find and start a particular Interactive Reporting Web Client executable based on its version. The Interactive Reporting Web Client Launcher that provides 6x/8x co-existence has been enhanced for 8.3/8.5 and future co-existence. There is a single launcher in the system associated with the .bqy mime-type and file
If an user installs the 8.x version over theReporting and Analysis installation, then the use needs to installed the Oracle's Hyperion Reporting and Analysis version again in order to have both work correctly.
