Setting Up the Job Scheduler

UnpublishExpiredJob
Expired certificates are not automatically removed from the publishing directory. If
you configure a Certificate Manager or Registration Manager to publish certificates
to an LDAP directory, over time the directory will contain expired certificates.
The job checks for certificates that have expired and are still
UnpublishExpiredJob
marked as published in the internal database at the configured time interval. The job
connects to the publishing directory and deletes those certificates; it then marks
those certificates as unpublished in the internal database. The job also collects a
summary of expired certificates that it deleted and mails the summary to one or
more agents or administrators as specified by the configuration.
Note that the job automates removal of expired certificates from the directory. You
can also remove expired certificates manually following the instructions outlined
in section "Updating Certificates and CRLs in a Directory," on page 660.
You can create additional automated jobs using the CMS SDK.
Setting Up the Job Scheduler
The Certificate Manager and Registration Manager can execute a job only if the Job
Scheduler is turned on (or enabled). As a part of turning the Job Scheduler on, you
also specify the frequency at which the Job Scheduler daemon should check if any
of the configured jobs need to be executed.

Frequency Settings for Automated Jobs

The Job Scheduler uses a variation of the Unix entry format to specify
crontab
dates and times for checking the job queue and executing jobs. As shown in Table
13-1, the time entry format consists of five fields (the sixth field specified for the
Unix is not used by the Job Scheduler). Values are separated by spaces or
crontab
tabs.
Each field can contain either a single integer or a pair of integers separated by a
hyphen ( ) to indicate an inclusive range. To specify all legal values, a field can
-
contain an asterisk rather than an integer. Day fields can contain a
comma-separated list of values. The syntax of this expression is:
(Minute) (Hour) (Day of Month) (Month of Year) (Day of Week)
