A system job folder contains a set of scalars that store information about the system job. System folder scalars have read-only access. Therefore, an application cannot set scalar values for a system job folder.
A system job folder has the following scalars:
"microsoft\SMS\mini-job"
"microsoft\SMS\site_job"
"microsoft\SMS\nad_transfer"
The time specifies the date and time after which the Scheduler activates the job and begins sending the job to the target sites. Note that the Scheduler uses the SQL Server time to evaluate the activation time. Also note that this time is written directly to the site database, that is, no time zone conversion is done.
The priority setting is used to ensure that higher priority jobs are sent before lower priority jobs. A High priority tells the Scheduler to send the job to a target site before any other jobs with lower priority.
For example, if a Sender is sending a Medium or Low priority job and the Sender detects a High priority job in one of its outboxes, the Sender will suspend the sending of the lower priority job and send the High priority job first. After the High priority job has completed, the Sender will resume sending the lower priority job that was suspended.
In addition, an outbox can be set to process all jobs, only higher priority jobs, or no jobs at specified days and times.
High has priority over Medium and Low; Medium has priority over Low.
The intervals range from Daily (every 24 hours after the Activate time) to Monthly. The interval is based on the SMS system time. A repeated job generates a new job each time that interval elapses.
