3.2. Timer Jobs
Timer
jobs are created when service applications, Web applications, and other
SharePoint components are created. When you create these components, a
job is also created to perform a specific task at a specified frequency.
For example, when you create a
new Web application, a disk quota warning job definition will be
created that by default runs once a week. This timer job monitors quota
limits to determine if either the warning or maximum thresholds have
been attained. The job definition will trigger the necessary actions
specified by the job.
3.2.1. Review Job Definitions
The Job
Definitions page displays information about all the current definition
jobs that are created. Each entry contains the following three columns,
as shown in Figure 30.
Title You may see duplicate titles that are associated with different components.
Web Application Displays the name of the specific Web application the definition is running against.
Schedule Shows the frequency of the timer job—how often it is scheduled to run.
You will notice that some job
definitions are listed only once. Normally, these job definitions are
system jobs or farm level jobs, or they belong to a specific service
application and there is only one occurrence of that application. Other
jobs may be listed multiple times because each job is associated with a
specific Web application; an example is the Disk Quota Warning job.
For additional information on a
job definition listed on this page, click the title of the job, which is
a hyperlink. This will display more details about the job, including a
description, the application it is associated with, and the last time it
ran. Additional options that can be configured are also available on
this page and allow you to change the schedule, run the job immediately
instead of waiting for the next scheduled time, or disable the job to
prevent it from running. To select one of the following options, click
the definition title.
Change The Schedule
Run The Job Now
Disable The Job
Note:
After you change the schedule, be sure to click OK to save your changes or the changes will not be applied.
Some job definitions are created
only when a specific operation is being performed. For instance, if you
are performing a backup, a job is created and will appear in this list.
If a job created for a specific operation becomes corrupted, you can
access it by clicking the hyperlink title for the job. Then click Delete
to end the operation and remove the job from the list on the Job
Definitions page.
Note:
You will get the Delete
option only for jobs that were created to run in association with a
specific operation. Jobs that are scheduled to run repeatedly have the
Disable option instead of the Delete option.
3.2.2. Check Job Status
The Timer Job Status page provides job status information in the following three categories.
Scheduled Displays the next 10 jobs scheduled to run.
Running Displays the jobs currently running.
History Displays the history of the jobs that have run.
To see additional jobs within
each category, you can click the hyperlink category title, or you can
click the hyperlink button that displays the current number of items
being displayed, which is located at the bottom of the category list, as
shown in Figure 31.
Alternatively, you can filter
the jobs displayed using the View drop-down menu at the upper right of
the page, which allows you to reduce the number of jobs being displayed
using one of the following five categories.
All
Service Applications
Web Applications
Server
Job Definitions
Also, there are five links at
the upper left of the page that you can use to display only the jobs
that fall within one of the three categories previously introduced, go
to the Job Definitions page, or refresh the current page using the Timer
Job Status link.
