The vendor's newly launched, much-hyped in-memory processing database option is turned on by default, according to one expert.

There's no question Oracle wants a large number of its database customers to use the in-memory option, which it's using as a hedge against customer defections to rival in-memory platforms from SAP, Microsoft and IBM.

Oracle's approach creates an in-memory column store, which dramatically speeds up analytic queries, while preserving the database's existing relational row store for OLTP (online-transaction-processing) workloads. The column store mitigates the overhead required to maintain row-based analytic indexes, improving OLTP performance.
