You can start ASET interactively, or you can use the -p option to request that the ASET tasks run at a scheduled time. You can run ASET periodically, at a time when system demand is light. For example, ASET consults PERIODIC_SCHEDULE to determine how frequently to execute the ASET tasks, and at what time to run the tasks. For detailed instructions about setting up ASET to run periodically, see How to Run ASET Periodically.
The format of PERIODIC_SCHEDULE follows the format of crontab entries. For complete information, see crontab(1).
