Scheduled task in Oracle 8i

Dear All,

I have Oracle 8.1.7 installed on Win NT server. Now I have written a procedure in my database called PROC_DEMO. I want to run this procedure on specified date and time.

How can I do this ?

Please explain in detail.

Regards,
Manish.

You can use DBMS_JOB package:

To submit a job:
DBMS_JOB.SUBMIT(ID OUT BINARY_INTEGER,                
                             what IN VARCHAR2,                
                             next_date IN DATE,                
                             interval IN VARCHAR2,                
                             no_parse IN BOOLEAN)

ID                              Unique job number
What                         The PL/SQL code or stored procedure
Next_date                   The date when the job will execute.  Default
                                 is SYSDATE.
Interval                       A function that calculates the next time the
                                 job is to execute.  Default is NULL.
No_parse                    If TRUE, Oracle parses the code the first
                                 time the job is executed.  If FALSE,
                                 the job is parsed when submitted.  Default is
                                 FALSE.

Ex: DBMS_JOB.SUBMIT(1234,<procedure_name>, sysdate,'sysdate+1')

To remeove a job:

DBMS_JOB.REMOVE(ID  IN  BINARY_INTEGER);

To change a job:

DBMS_JOB.CHANGE(ID IN BINARY_INTEGER,                
                                 what IN VARCHAR2,                
                                next_date IN DATE,                
                                interval IN VARCHAR2);

To run a job immediate:

DBMS_JOB.RUN(ID IN BINARY_INTEGER);

You also have DBMS_JOB.WHAT/NEXT_DATE/INTERVAL/BROKEN ...

I tried the following command and got errors :

SQL> BEGIN
  2  DBMS_JOB.SUBMIT(1, PROC_TEST, SYSDATE, SYSDATE+1);
  3  END;
  4  /
DBMS_JOB.SUBMIT(1, PROC_TEST, SYSDATE, SYSDATE+1);
                   *
ERROR at line 2:
ORA-06550: line 2, column 20:
PLS-00222: no function with name 'PROC_TEST' exists in this scope
ORA-06550: line 2, column 1:
PL/SQL: Statement ignored

Here PROC_TEST is a vaild procedure.

Why did this error occur ?

I tried the following and got a new error :

SQL>declare

  3    begin
  4      dbms_job.submit(x,  'proc_test', sysdate, 'sysdate+1');
  5*   end;
declare

This should work:

SQL>declare
2   x number(3);
3   BEGIN
4   dbms_job.submit(x, 'PROC_TEST', sysdate, 'sysdate+1', TRUE);
5   commit;
6   end;

Thanks,

How do I setup a scheduled task on Oracle 8i for 9:30AM, 11:30AM, and 2:30PM to run everyday?
sjensen26Commented:
And dba_jobs view does not work.
sjensen26Commented:
I answered my own question. But I still can't get dba_jobs view to work. How do you do it at a specfic time? You create multiple jobs.

declare
x number(10);
g number(11);
h number(12);

BEGIN

dbms_job.submit( x, 'PROCEDURE_NAME;', TRUNC(SYSDATE)+8/24, 'TRUNC(SYSDATE)+1+8/24', TRUE );
dbms_job.submit( g, 'PROCEDURE_NAME;', TRUNC(SYSDATE)+11/24, 'TRUNC(SYSDATE)+1+11/24', TRUE );
dbms_job.submit( h, 'PROCEDURE_NAME;', TRUNC(SYSDATE)+14/24, 'TRUNC(SYSDATE)+1+14/24', TRUE );

commit;
end;
/
