Re: Oracle is Very Late to the Game on this Concept
What you say about IBM's CICS technology may be true, but IBM only recently added in-memory technology to its flagship DB2 database by way of the BLU Acceleration for DB2 feature, introduced in 2013. I'm fairly certain it's an extra-cost option. BLU acceleration applies only to analytic querying, not transactional performance.

Oracle Database In-Memory applies acceleration to selected analytical queries, and if you can eliminate query indexes, you can also accelerate transactional performance by two to four times, according to Oracle. SAP's Hana In-Memory Database runs entirely in memory, not just against selected tables or partitions, and improves transactional and analytical performance. Microsoft's In-Memory OLAP feature for SQL Server 2014 applies only to transactional perfomance.

Reader comments that options shouldn't be treated like features
Reader Dave Schmidt submitted the following comment via email:

Based on the passage below (underlined words my emphasis), Oracle is putting it to customers. What they are describing is a feature disabled for marketing purposes, not an option.

Oracle's Monday blog post, titled "Getting started with Oracle Database In-Memory," explains that the feature is installed automatically with the latest release because it's an intrinsic part of the database, "not a bolt-on technology," writes Maria Colgan, master product manager of the feature. But enabling the option requires a deliberate, two-step process, she explains. All opinions expressed here are personal. -- Dave Schmidt
