Adaptive Server introduces a Job Scheduler automatic restart feature that is implemented during various states of Job Scheduler Agent (JS Agent) and Job Scheduler Task (JS Task).
This may be as a result of the connection in a pool stopping, or if the target server has stopped while collecting results.
In this situation, both the JS Task and JS Agent are shut down and restarted.
This may be as a result of an inconsistency detected in Job Scheduler tables; alternatively, it may be due to incorrect or missing job callouts.
In this situation, both the JS Task and JS Agent are shut down and restarted.
This may be as a result of JS Agent hitting a fatal signal, JS Agent shutting down due to inconsistency detected in its operation, or an external event, such as the killing of a JS Agent process.
JS Task periodically monitors JS Agent health. If it finds that the JS Agent has stopped, it will restart the JS Agent.
In this situation, you must manually restart Adaptive Server. A new JS Task aborts the existing JS Agent, if any, and starts a new JS Agent.
