Concepts

JS Task wakes up on demand, either by a job scheduled to be run or by a wake-up event that has occurred, such as the creation of a new job. At regular intervals (configurable by the database administrator), JS Task scans the sybmgmtdb database tables and collects applicable schedule information to maintain its dedicated server tables js_callouts and js_history. The JS Task performs the functions that allows Job Scheduler to perform its internal tasks. It is also what makes Job Scheduler run time programmable within ASE.�
