Expression Tracking Feature Cannot Be Turned Off By OPTIMIZER_FEATURES_ENABLE
Last updated on DECEMBER 18, 2017
Applies to:Oracle Database - Enterprise Edition - Version 126.96.36.199 and later
Information in this document applies to any platform.
According to Oracle Reference documentation, Expression Tracking feature is enabled only when OPTIMIZER_FEATURES_ENABLE parameter is set to 188.8.131.52.
However, setting OPTIMIZER_FEATURES_ENABLE=184.108.40.206 or 220.127.116.11 still collects expression tracking information into dba_expression_statistics.
