Scheduler Job by Node (RAC Database)

Sometimes you want to run something just in one node of the RAC. Here is an example to do it:

create or replace procedure USER_JOB.PRC_SOMETHING is
begin
-- do something
null;
end;
/

begin
sys.dbms_scheduler.create_job(job_name => 'USER_JOB.JOB_SOMETHING',
job_type            => 'PLSQL_BLOCK',
job_action          => 'USER_JOB.PRC_SOMETHING;',
start_date          => sysdate,
repeat_interval     => 'Freq=Minutely;Interval=30',
end_date            => to_date(null),
job_class           => 'DEFAULT_JOB_CLASS',
enabled             => true,
auto_drop           => false,
comments            => 'Something Job.');
end;
/

begin
dbms_scheduler.set_attribute(name => 'USER_JOB.JOB_SOMETHING',
 attribute=>'INSTANCE_ID', value=> 1);
end;
/
