Oracle : Ошибка ORA-04032

"pga_aggregate_target must be set before switching to auto mode"
*Cause: attempt to set workarea_size_policy to AUTO while
pga_aggregate_target is not specified
*Action: before setting workarea_size_policy, set pga_aggregate_target
to a value representing the total private memory available to
the instance. This total is generally the total physical memory
available in the system minus what is needed for the SGA minus
what is needed for the operating system (e.g. 500MB)
