To set a limit in a job class, review the following code example:

set classDescription "A template for a FOO class"
set classEditable     1
lappend VOV_JOB_DESC(resources) License:FOO
lappend VOV_JOB_DESC(resources) Limit:FOO_@USER@
lappend VOV_JOB_DESC(resources) Limit:FOO_@GROUP@
lappend VOV_JOB_DESC(resources) CPUS/1 percent/1 RAM/20

     # Revoke requested/not-used resources after 2 minutes.
     vtk_jobclass_set_revocation_delay "FOO" 2m
 
     # Warn after 2h, kill after 4h of idleness.
     vtk_jobclass_set_idle_delays    "FOO" 2h 4h
 
     vtk_jobclass_set_max_reschedule "FOO"  2
