The job information in CA WA Agent is persistence data (it has database so to speak). The Agent will continue to call Autosys or scheduler till it gets an acknowledgement. Once the scheduler acknowledges that it has received the job information, the Agent will clear the data on its side.
So, if Autosys is down, the WA Agent will keep trying to send the update about job. Same applies to WA Agent, if it is shutdown, all the data is still there. When it comes back up it will re-read and try to send whatever job information it was suppose to.
