Houston – we have deleted all SYS DBMS_SCHEDULER Jobs !

Bad, bad PL/SQL…. A customer of me has executed a simple script to cleanup DBMS_SCHEDULER jobs and programs for an application. Unfortunately he did as user SYS. The content of the SQL script: BEGIN FOR JOB IN (SELECT * FROM USER_SCHEDULER_JOBS) LOOP DBMS_SCHEDULER.DROP_JOB(JOB_NAME => JOB.JOB_NAME, FORCE => TRUE); END LOOP; FOR PROG in (select * from USER_SCHEDULER_PROGRAMS) LOOP DBMS_SCHEDULER.DROP_PROGRAM(PROGRAM_NAME => PROG.PROGRAM_NAME, FORCE => TRUE); END LOOP; END; / All the Oracle internal maintenance jobs and programs like the AUTO_SPACE_ADVISOR_PROG, GATHER_STATS_PROG,…
