eng Influence of Oracle hints on query execution This paper deals with the influence of the Oracle Optimizer hints (sql hints) usage on the query execution. It is the part of parallel computing for data storage as the result of parallel computing. We test the comparison of the classic SQL queries execution towards SQL queries which use Oracle hints. It also examines how the efficiency is influenced by the presence of indices when using hints, how the hints behave when connecting several tables in a query and how the hints are influenced by the chosen Oracle optimizer mode. The CPU time is the basic criterion for the assessment of the efficiency Oracle; hints; query execution
