Job scheduling in oracle 10g

The DBMS_JOB, DBMS_SCHEDULER packages are installed when the Oracle database is installed. The dbmsjob.sql script has source code of DBMS_JOB. In Oracle 10g the DBMS_JOB package functionality is replaced and/or enhanced by the DBMS_SCHEDULER package. The DBMS_JOB package is depricated and provided for backward compatibility only.

'CREATE JOB' privilege is required to create and run jobs.

There are vaious methods to do job scheduling in oracle 10g but the simple method of scheduling a job is as follows. ( I used couple of times hence thought good to post here)..


create or replace package pkg1
as
procedure makeentry;
end pkg1;
/

create or replace package body pkg1
as
procedure makeentry
is
begin
insert into test1 values (to_char(sysdate, 'dd/mm/yyyy hh24:mi:ss') );
commit;
end;
end;


BEGIN
dbms_scheduler.create_job(
job_name => 'makeentry',
job_type => 'STORED_PROCEDURE',
job_action => 'PKG1.MAKEENTRY',
repeat_interval => 'FREQ=DAILY;BYHOUR=13;BYMINUTE=0;BYSECOND=0',
comments => 'cleanup job runs every day at 1 pm',
enabled=>true);
END;

Specifying Intervals

FREQ takes YEARLY, MONTHLY, WEEKLY, DAILY, HOURLY, MINUTELY, and SECONDLY.
FREQ=DAILY; INTERVAL=7 executes a job every 7 days
FREQ=HOURLY; INTERVAL=2 executes a job every other hour
FREQ=WEEKLY; BYDAY=FRI executes a job every Friday.
FREQ=WEEKLY; INTERVAL=2; BYDAY=FRI executes a job every other Friday.
FREQ=MONTHLY; BYMONTHDAY=1 executes a job on the last day of the month
FREQ=YEARLY; BYMONTH=DEC; BYMONTHDAY=31 executes a job on the 31st of December.
FREQ=MONTHLY; BYDAY=2FRI executes a job every second Friday of the month

.. Hope this help you as well.....
