I have a SQL job schedule to run daily. There are 8 jobs running with the same schedule. 6 jobs run properly. The remaining two run only once when i start the jobs manually, subsequent recurring runs never happen. There is no information about these two in job history.
It looks like the scheduler does not invoke the mentioned two jobs at all.
Workaround: set the schedule to run once in 24 hours, added start time and end times with 30 minutes of interval.

I am using mysql 5.7 and I scheduled some simple BI calculation using events.
The events are scheduled every 1 hour and I need to know duration of each execution to evaluate if the event can be scheduled every 30 mins.
I can use
SELECT * FROM INFORMATION_SCHEMA.events;
to find events' status, last run time, last altered time, etc. But where to find the execution log of events?
Consider a situation, we've scheduled a job which backups(Full) database at a interval of 2 hrs. Similarly two more jobs are scheduled, one for the differential and another for log backup scheduled at interval 30 mins and 5 mins each . We've started job ,After two hours all the three jobs will be fired(Full,Differential,Log) therefore which will be done first as they all are scheduled to same time.
1) If Full BackUp is performed, then diff(backup) will be of Zero changes?
2) Similarly what will be case of transaction, and how can we know which fired first rather than using LSN (EASY METHOD to know).
I have a sequence container with a sequence of execute package jobs. I want those jobs to execute every 10min. is there a way to insert poller that executes the sequence container every 10min?
A clean solution would be to schedule the task inside of sql server agent to run every 10 minutes.
If you do not have this option, you can add a script task that will poll every x seconds, however this is not ideal
Depending on your scenario, this may be useful make-an-ssis-package-delay-or-wait-for-data
I am trying to use mysql event schedule in my application, I have not use it before so i have some confusions.
I want to know if my computer is off on the schedule date, then schedule will continue on next day, after starting my computer?
Like:
my schduled is for beginning at every month (no predefined time set)
if in the above date my computer/Server is off,
will mysql continue scheduled event in next day after turning on my computer/server?
If no, then please suggest a solution.
Hmmmm, have you looked at something like this?
MySQL: Using the Event Scheduler
... or:
How to create MySQL Events
... or even: [MySQL :: MySQL 5.1 Reference Manual: 19.4.1. Event Scheduler Overview](19.4.1. Event Scheduler Overview)?
Also please keep in mind that SQL DBMS servers are written with the rather strong presumption that they will be kept up and operating 24 hours per day with only brief periods of downtime for maintenance or repairs. There is generally very little consideration for operation on machines which are shutdown at night and while not in use.
If you simply store a table of dates and events then your can simply query that table for events which have passed or are upcoming within any range you like ... and you can run the program(s) containing those queries (and performing any appropriate activities based on the results) whenever you start you computer and periodically while it's up and running.
These links refer to a feature of MySQL which is designed to have the server internally execute certain commands (MySQL internal commands, such as re-indexing, creating/updating views, cleaning tables of data which "expires" and so on. I don't know if a MySQL server would attempt to execute all events which have passed during downtime, though it should only be a little bit of work to follow the tutorial, schedule some event for some time (say 15 minutes after the time you expect to hit [Enter]) ... then shutdown your computer (or even just the MySQL server) and go off to lunch. Then come back, start it up and see what happens.
The scheduled event could be something absurdly simple, like inserting the "current" time into some table you set up.
I'm building a small reminder application in Rails and I want to add the ability for my users to be able to create a cron job. The cron job would run on a given day each week, each month or even one time depending on the users selection and save.
So the user creates the even, selects if its weekly, daily or one time, then it creates the cron job to run a command line in linux.
Any gems for that to be easier?
The common way would be to have database table with maybe:
status | linux_command | execute_at
and to run every 10 mins a cronjob witch checks the database and executes the command.
