| Parameter type | String |
| Syntax | WORKAREA_SIZE_POLICY = { AUTO | MANUAL } |
| Default value | AUTO |
| Modifiable | ALTER SESSION, ALTER SYSTEM |
WORKAREA_SIZE_POLICY specifies the policy for sizing work areas. This parameter controls the mode in which working areas are tuned.
Values:
AUTO
Work areas used by memory-intensive operators are sized automatically, based on the PGA memory used by the system, the target PGA memory set in PGA_AGGREGATE_TARGET, and the requirement of each individual operator.
MANUAL
The sizing of work areas is manual and based on the values of the *_AREA_SIZE parameter corresponding to the operation (for example, a sort uses SORT_AREA_SIZE). Specifying MANUAL may result in sub-optimal performance and poor PGA memory utilization.
