Specifies the percent of prefetch resources designated for sorting objects.
Option can be set at the database (PUBLIC) or user level. When set at the database level, the value becomes the default for any new user, but has no impact on existing users. When set at the user level, overrides the PUBLIC value for that user only. No system privilege is required to set option for self. System privilege is required to set at database level or at user level for any user other than self.
Requires the SET ANY PUBLIC OPTION system privilege to set this option. Can be set temporary for an individual connection or for the PUBLIC role. Takes effect immediately.
PREFETCH_SORT_PERCENT designates a percentage of prefetch resources for use by a single sort object. Increasing this value can improve the single-user performance of inserts and deletes, but may have detrimental effects on multiuser operations.
Do not set this option unless advised to do so by Technical Support.
