Hello list,
I have a strange problem when trying to create a job using the DBMS_SCHEDULER
package:
I verified that the job name does not exists using the following statements:
(All the following statements have been run using the same Oracle user: MY_USER)
select count(*)
from all_scheduler_jobs
where upper(job_name) = 'MY_JOBNAME';
==> returns 0
select count(*)
from all_scheduler_running_jobs
where upper(job_name) = 'MY_JOBNAME';
==> returns 0
select count(*)
from all_jobs
where upper(what) like '%MY_JOBNAME%'
==> returns 0
select count(*)
from all_scheduler_chains
where upper(chain_name) = 'MY_JOBNAME';
==> returns 0
select count(*)
from all_scheduler_groups
where upper(group_name) = 'MY_JOBNAME';
==> returns 0
select count(*)
from all_objects
where upper(object_name) = 'MY_JOBNAME';
==> returns 0
execute DBMS_SCHEDULER.drop_job(job_name => 'MY_JOBNAME', force => true);
==> ORA-27475: "MY_USER.MY_JOBNAME" must be a job
But when I try to create a job with that name using:
execute DBMS_SCHEDULER.create_job(job_name => 'MY_JOBNAME', job_type =>
'PLSQL_BLOCK', job_action => 'begin ... end;', enabled => TRUE);
I get the following error: ORA-27477: "MY_USER.MY_JOBNAME" already exists
If I use a different job name (e.g. MY_JOBNAMEX) I can create and drop the job
without problems.
Does anyone have an idea on where else I could look for an object with that
name that prevents creating the job?
I am using Oracle 11.2.0.3 on CentOS
Thanks in advance
Thomas
