Executing DBMS_STATS.GATHER_SYSTEM_STATS in interval mode as a user who has been granted the GATHER_SYSTEM_STATISTICS role fails with an ORA-27486 insufficient privileges. Executing the procedure in default mode runs without any errors.
Here is an example illustrating the error:
SQL> create user test1 identified by test1;
SQL> grant create session, gather_system_statistics to test1;
BEGIN DBMS_STATS.GATHER_SYSTEM_STATS(gathering_mode=>'INTERVAL', interval=>1); END;
ERROR at line 1:
ORA-20003: Unable to gather system statistics
ORA-06512: at "SYS.DBMS_STATS", line 14248
ORA-06512: at line
Upgraded the database from 9.2 to 10g.
