If enabled, then the
job execution service checks the identity and the job characteristics
to make sure the identity making the request meets the assigned permissions. For more information,
see Job Execution Service Roles.

Jobs are kept in memory
only if persistence is disabled. If persistence is disabled and the
SAS Web Infrastructure Platform Services Web application or the Web
application server is stopped, then there are no records written to
the SAS Web Infrastructure Platform database about any jobs that were
submitted. When persistence is enabled, the job execution services
can restart any jobs that were submitted, queued, or running. For
jobs that are complete, clients can fetch the results after a restart,
when persistence is enabled.

You can associate resources
with servers and then a job can specify that it requires a resource.
For example, you can associate a printer name with SASApp. When a
client submits a job, and specifies that it requires the printer resource,
the job execution service makes sure that the job runs on that server
even when other servers are available.
