Object documentation Catalog Cache Locate the document in its SAP Library structure

The catalog cache of a database instance stores the database catalog objects most recently used by a database session and the internal representation (execution plans) of the most recently executed SQL statements.

One catalog cache exists for each database session. You can configure its size using the special database parameter CAT_CACHE_SUPPLY. The hit rate should be above 85 percent.

Data that is displaced from the catalog cache is stored in the data cache.
