In-Memory Oracle Database Speeds Up Applications
Page 1 of 1
Oracle has been talking about adding in-memory capabilities to its database since OracleWorld in September 2013. At an event this week, the company once again was talking about the impact that in-memory will provide to its database and more importantly, to the applications that run on top of it.
Tim Shetler, Oracle vice president of product management, told Enterprise Apps Today that the in-memory database feature for the Oracle 12c database is set to be generally available in the next 60 days. The in-memory capability will be a licensed feature that users will need to pay for. Shetler noted that Oracle has not yet formally announced pricing for the in-memory feature.
What Oracle has announced is why and how the in-memory features will impact application performance. The key is the fact that with the in-memory feature , the database now stores data in both column and row formats. The bits for the columnar database are stored in memory, which eliminates the need for the on-disk database to store certain classes of index files.
