Oracle Database In-Memory option was released with Oracle
Database 12c (12.1.0.2) and the In-Memory Advisor (IMA) has been much awaited
since then. The Oracle Database In-Memory is designed to achieve the following
goals:
- Speed up analytical queries
- Speed up OLTP transactions
- NO application changes
Without the In-Memory Advisor, a DBA has to manually identify
the tables to be placed in the In-Memory Column Store (IMCS). This manual task
is no more required as the IMA, analyzes the analytical workload of the
database and produces a recommendation report (which includes SQL commands to
place the tables in IMCS).
For more information on IMA please refer to MOS:
