Oracle Database In-Memory Now Available in 12.1.0.2 Download

Oracle Database In-Memory transparently accelerates analytic queries by orders of magnitude, enabling real-time business decisions. Using Database In-Memory, businesses can instantaneously run analytics and reports that previously took hours or days.  This is possible due to a unique "dual-format" architecture that enables data to be maintained in both the existing, Oracle row format, for OLTP operations, and a new, purely in-memory column format, optimized for analytical processing

Oracle Database In-Memory accelerates both Data Warehouses and mixed workload OLTP databases, and is easily deployed under any existing application that is compatible with Oracle Database 12c. No application changes are required.

Oracle Database In-Memory capability is included in Oracle Database 12c Release 1 Patchset 1 (12.1.0.2).  (However, it is disabled by default.)  There is no need to select any special component during installation or to perform any special relink operation.  It has been seamlessly integrated into the core of the database as a new component of the Shared Global Area (SGA).  When the Oracle Database is installed, Oracle Database In-Memory is installed.
