Background documentation Cache Locate the document in its SAP Library structure

To prevent the hard disks being accessed unnecessarily, read and write operations are buffered by the database system in caches in the main memory.

The database system uses the following caches, among others:

·        Catalog cache

·        I/O buffer cache (contains the data cache and converter)

·        Log queue

You can configure the caches using database parameters.
