Somehow after updating the interval the next data is being increment little by little, is like the next run is the date of execution plus the interval.

I can’t seem to run a job every 3 hours after 16:50, lets say:

16:50, 19:50, 22:50 …

We are submitting stored procedures thru the DBMS_JOB.SUBMIT subprogram. I would like the stored procedure submitted in this to log it’s job number (select job from user_jobs). Is there any way to access the job id from within that process?

thanks

Stephane,

Oracle does provide the ability to apply a trigger after database startup and/or before database shutdown. Care should be used with these triggers as they may slow startup and shutdown but it is possible.

Check out this page for some command reference:

Hi Tim,

I want to know if is possible to run a job after every database startup… I dont see how I can do this. the repeat interval of DBMS_SCHEDULER don’t allow this choice? I use Grid Control to set up my jobs.

Thanks for the help
Stéphane

Hashmi,

I don’t think you can build a non-time based condition into the dbms_job portion, but you could certainly build your condition into a procedure and call the procedure with the scheduler.

I think you’ll be happier with this approach anyway as it will keep the scheduled job as simple as possible.

I have a question about DBMS_JOB.
How can I put a condition inside a DBMS_JOB packge that, if condition gets true, JOB will run otherwise job will not run.

Ashwath,

If you’re looking for when the next execution of a given job will be you can just select the NEXT_DATE column from the user_jobs table. The INTERVAL column is stored as text (a varchar2) so will not evaluate to a date as easily as you want.

Hope this helps.

Is there a way to query user_jobs table and get the ‘interval’ as date type?

Assume that the only row in user_jobs has interval as TRUNC(SYSDATE+1/24,’HH24′).

I thought something like this would do the trick:

select (select interval from user_jobs where rownum=1) from dual;

Ya’ll know it better than me… that won’t work. That will prompty return TRUNC(SYSDATE+1/24,’HH24′).

Although

select TRUNC(SYSDATE+1/24,’HH24′) from dual;

returns what I wanted.

We have the interval specified in bazillion different ways in our database. Some examples:

sysdate + 1/288

sysdate + 1/480

TRUNC(SYSDATE+1,’DD’)+ 1/48

TRUNC(SYSDATE)+1

sysdate + 1/48

TRUNC(SYSDATE+1/24,’HH24′)

sysdate+1/480

TRUNC(SYSDATE+1,’DD’)

sysdate + 72

sysdate+1
