Coming to OpenWorld 2018? Be sure to visit the TidalScale booth in Moscone South
and learn how to solve performance problems and lower costs with Software Defined Servers. Before you visit the booth, or if you can't
make it this year, check out TidalScale at www.tidalscale.com. Be
sure to click on the Solutions link and look through the Oracle resources.
This package is deprecated and has been supplanted by DBMS_SCHEDULER. If you have any code using this package it is recommended that you move it to DBMS_SCHEDULER as part of migrating to 12c.
Unique constraint (SYS.I_JOB_JOB) violated
Interval must evaluate to a time in the future
Execute daily 'SYSDATE + 1'
Execute once per week 'SYSDATE + 7'
Execute hourly 'SYSDATE + 1/24'
Execute every 10 min. 'SYSDATE + 10/1440'
Execute every 30 sec. 'SYSDATE + 30/86400'
Do not re-execute NULL
JOB An output parameter, this is the identifier assigned to the job you created. You must use this jobnumber whenever you want to alter or remove the job.
WHAT This is the PL/SQL code you want to have executed. The WHAT parameter must end with a semi-colon.
NEXT_DATE The next date when the job will be run. The default value is SYSDATE.
INTERVAL The date function that calculates the next time to execute the job. The default value is NULL. INTERVAL must evaluate to a future point in time or NULL.
This parameter is a VARCHAR2 and must be enclosed in single quotes.
NO_PARSE This is a flag. If NO_PARSE is set to FALSE (the default), Oracle parses the procedure associated with the job.
If NO_PARSE is set to TRUE, Oracle parses the procedure associated with the job the first time that the job is executed.
If, for example, you want to submit a job before you have created the tables associated with the job, set NO_PARSE to TRUE.
Submit a job with a job number selected from sys.jobseq
