Custom scheduling of iBots

Question

I posted the following to the siebel-analytics user group so I apologize in advance for the cross posting.
However, I have a fast approaching deadline and I am hoping that someone on this forum can help me understand the background processes behind Delivers. What I would like to do is to call an iBot from a pl/sql package. I see that the S_NQ_SCHED schema contains four files. When I schedule a job to run I noticed that the S_NQ_JOB table is updated with the various timestamps pertaining to the scheduled iBot's job_id that I would like to run. The columns of interest I believe are shown below in the update statement I've written:
update s_nq_sched.s_nq_job set next_runtime_ts = to_date('30-May-2008 16:26:00', 'dd-Mon-yyyy HH24:MI:SS'),
begin_year = 2008,
begin_month = 5,
begin_day = 30,
start_hour = 9,
start_minute = 26,
end_hour = 9,
end_minute = 26
where job_id = 21
where the next_runtime_ts is the GMT.
If I schedule a job to run in Delivers and then change the next_runtime_ts (and the other above mentioned columns) via my update statement then Delivers will run the job at the newly specified time. If I don't schedule a job in Delivers and just update the next_runtime_ts (et. al.) column of the existing record (where job_id = 21 in above example) then the job does not run. Do you know of the background processes Delivers runs that check to see when to run the next scheduled job? And how that process is initiated? I believe the job that I'm scheduling through Delivers is being cached so is there a programmatic way to turn off/refresh the cache?
Any help or direction you can offer would be greatly appreciated.

Joseph

Answer 1

Joseph,
This is what i understand from your post.
1. Need to know the background of delivers
2. How to turn off cache or delete cache.
1. Dashboard delivers is the process by which users can create jobs which they want to occur on a regular basis. Dashboard delivers uses job schedular to schedule and execute the jobs. So every time you create a Ibot in dashboard a job is created in the job schedular but it also created a atr file in the users/ibot user/delivers folder. So job manager uses the entry made in job schedular to execute the specified dashboard job.
2. You can either turn off cache or purge cache. Choice is your depending on your requirement. To turn off you can set the parameter in nqsconfig.ini file. To purge you can create a purge script and schedule it through job manager. There different ways by which you can purge a cache..by user who created or by subject area, or complete or by database it is hitting.
Hope this answers your question.
