The SYSTEM_CACHES catalog table stores the definitions of the caches created on remote tables. The data in the SYSTEM_CACHES table provides the name, type (single table or relational), status, and other information for each defined cache. The table name returned for a remote relational cache is the name of the primary table of the relational cache; however, its type is REMOTE RELATIONAL. You can query SYSTEM_CACHES to determine the caches currently defined by the driver. The values in the SYSTEM_CACHES table are read-only. The referenced tables of a relational cache can be determined by querying the SYSTEM_CACHE_REFERENCES catalog table (see SYSTEM_CACHE_REFERENCES Catalog Table).
