How To Enable Flashcache Compression?

Answers

Beginning with Exadata Storage Server Software 11.2.3.3.0 Oracle introduce a new Feature named Flash cache compression. The goal of Flash cache compression is to dynamical and transparently compressing user data when it is loaded into the flash cache. This increase the logical capacity of the flash cache because much more data is kept in the flash and decrease the I/O on the data disk. The compression and decompression operations are completely transparent to the application and database, and Oracle says that there is no performance overhead, even when running at rates of millions of I/Os per second. Please keep in mind that there are additional licenses needed to use this feature. Please refer to licensing requirements listed in the Exadata Licensing Guide before enabling this feature.
