PARALLEL_FORCE_LOCAL

Property Description
Parameter type Boolean
Default value false
Modifiable ALTER SESSION, ALTER SYSTEM
Range of values true | false
Basic No

PARALLEL_FORCE_LOCAL controls parallel execution in an Oracle RAC environment. By default, the parallel server processes selected to execute a SQL statement can operate on any or all Oracle RAC nodes in the cluster. By setting PARALLEL_FORCE_LOCAL to true, the parallel server processes are restricted so that they can only operate on the same Oracle RAC node where the query coordinator resides (the node on which the SQL statement was executed on).
