11.2 Update Window Details

One of the nice features introduced in recent oracle releases was automated maintenance jobs. This is a nice feature as oracle tries to automate STATS generation and automating execution of advisors.

Sometimes, however the default schedule for these maintenance jobs is not good enough, so to change these windows.

In a nutshell, you need to disable the window, set attributes, duration time, start time etc.

A sample would be:

BEGIN
DBMS_SCHEDULER.DISABLE(
name=>'"SYS"."SATURDAY_WINDOW"',
force=>TRUE);
END;

BEGIN
DBMS_SCHEDULER.SET_ATTRIBUTE(
name=>'"SYS"."SATURDAY_WINDOW"',
attribute=>'DURATION',
value=>numtodsinterval(1080, 'minute'));
END;

BEGIN
DBMS_SCHEDULER.SET_ATTRIBUTE(
name=>'"SYS"."SATURDAY_WINDOW"',
attribute=>'REPEAT_INTERVAL',
value=>'FREQ=WEEKLY;BYDAY=SAT;BYHOUR=3;BYMINUTE=0;BYSECOND=0');
END;

BEGIN
DBMS_SCHEDULER.ENABLE(
name=>'"SYS"."SATURDAY_WINDOW"');
END;
