2.6 Caching
2.6.1 Inserter Caching
Inserter caching is implemented by setting the statement attribute SQL_ATTR_PARAMSET_SIZE on the SQLHSTMT. Inserter caching is fully supported by the DB Access Module for DB2 CLI.
2.6.2 Reader Caching
Reader caching is implemented by setting the statement attribute SQL_ATTR_ROW_ARRAY_SIZE on the SQLHSTMT. Reader caching is fully supported by the DB Access Module for DB2 CLI.
Increasing the cache parameter when producing an RWDBReader increases the number of rows fetched at a time, which can improve performance. By default, the cache size is set at 10.
NOTE -- Increasing the cache size can improve performance.
