check your job_queue_processes parameter and make sure it is a non zero value

 

by: geotigerPosted on 2007-10-23 at 16:22:01ID: 20135350

It is 10:

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
job_queue_processes                  integer     10

 

by: konektorPosted on 2007-10-24 at 01:46:20ID: 20137167

after starting database there are operating system processes created, which serves jobs.
if jour job_queue_processes is 10, tha processes j001 - j010 are created.
this backround proocesses is used to serve actual jobs, so if you have planned let's say 100 jobs in dba_jobs at the same time, only 10 of them are executed and next are executed only after some job finishes.
if someone kills the process in operating system - this is probably reason when oracle detects that job process "died". i think new process is created to serve jobs after you kill one of job process, but i'm not sure. anyway after restart of database there will by 10 processes for jobs.

 

by: LindaCPosted on 2007-11-03 at 11:15:27ID: 20207693

Cause
JOB_QUEUE_PROCESSES parameter was set to 10 which is a small value.

JOB_QUEUE_PROCESSES specifies the maximum number of processes that can be created for the
execution of jobs. It specifies the number of job queue processes per instance (J000, ... J999).

That is why a lot of jobs died as in the alert log file when the parameter is set to such a small
value.

.
Solution
Make sure you are using SPFILE and then issue the following :

SQL>alter system set JOB_QUEUE_PROCESSES=500 scope=both;

Make sure that the value of the parameter has changed and then check if the error is still
generated in the alert log.
