SAP Adaptive Server Enterprise - In-Memory Database Option
SAP ASE offers two fully featured in-memory database options
- In-memory database (IMDB) ‒ a page-oriented, zero-disk footprint in-memory database that uses the SAP ASE buffer cache to provide in-memory storage for the entire database.
- In-memory row storage (IMRS) ‒ an in-memory, row-oriented storage cache that stores frequently accessed data from "hot" tables or partitions. Older, infrequently accessed data are stored in the page-based buffer cache. Distinct from an IMDB, only part of a disk-resident database's data is stored in-memory in an IMRS, while large amounts of the database are stored on disk, accessed through the buffer cache.
The IMDB and IMRS features require these licenses:
ASE_IMDB license to enable fully in-memory IMDB.
ASE_MEMSCALE license to enable an IMRS in a disk-resident database and to configure the features that require an IMRS.
