Faced a strange issue in oracle 12c. In automated maintenance task, sql tuning advisor was enabled. However, it was still not running. Validated dba_autotask_operation, that "sql tuning advisor" is enabled. However, view -dba_scheuler_job_run_details and dba_autotask_task showed that it was NOT running.
This is a bug in 12c.
As per metalink note, either we have to apply a patch"20540751" or as a workaround, run @?/rdbms/admin/execsqlt.sql to create the scheduler program "'AUTO_SQL_TUNING_PROG" that was dropped. This program should then show in in dba_scheduler_programs.
