Actually in Execute DBMS_JOB.SUBMIT(:Jobno,'Analyze_object(''TABLE'',''DEPT'');',SYSDATE+1/288) ,its said that this job will be done in 5 minutes from now.So can anyone explain how does 1/288 represent 5 minutes from now? Thanks.

In sysdate + 1, the one represent one day thus 24 hours.
1/288 is a fraction of the day.  So 24 hrs = 1440 minutes
1440 * 1/288 = 5 minutes.

5 (minutes) = 5/(24*60) (days)

1 day = 24*60 (minute)

1440 (1 day) divided by 5 (minutes) equals 288.

therefore

the current point in time + 5 minutes in an SQL Statement gets represented as

sysdate + 1/288

For a different number of minutes you would divide 1440 by the number of minutes you want and add 1/x to sysdate.
