Cautionary notes

For the service name of the JP1/AJS3 Database service, the setup identifier specified at installation is displayed. For the service name of the JP1/AJS3 Database ClusterService service that starts when the type of the embedded database is one used for JP1/AJS3 - Manager before version 10-00, the setup identifier specified at installation is also displayed. For details about the setup identifier, see the description of the -id option in ajsembdbsetup in 2. Commands Used during Setup in the manual JP1/Automatic Job Management System 3 Command Reference.
In UNIX, a superuser must start the above services.
The JP1/Base service and JP1/AJS3 service need to be active to define or execute work tasks in JP1/AJS3. Start the JP1/Base service before starting the JP1/AJS3 service. Stop the JP1/Base and JP1/AJS3 services when you finish defining or executing work tasks.
In a manager/agent configuration, you need to start and end the JP1/AJS3 service on both JP1/AJS3 - Manager and JP1/AJS3 - Agent.
Do not change the system date and time after starting the JP1/AJS3 service as this will affect the jobnet execution schedule. For details about this issue, see 7.9.3 Changing the date and time of the system in the JP1/Automatic Job Management System 3 Administration Guide.
When you start JP1/AJS3 - View to perform operations on a jobnet registered for execution from JP1/AJS3 - View, make the time zone of the JP1/AJS3 - View host the same as the time zone of the connected JP1/AJS3 service.

When you perform operations on a jobnet from JP1/AJS3 - View, the time in the time zone in which the JP1/AJS3 service is running is displayed in JP1/AJS3 - View. Therefore, if the time zones are different, the time of actual operations and the time displayed in JP1/AJS3 - View will be out of sync by the difference between the two time zones. For details, see 2.4.1 Time zones.
When using the Windows mail system linkage functionality, you can choose whether to use the JP1/AJS3 Mail service or the desktop mail monitoring process. If you choose the mail monitoring process, the JP1/AJS3 Mail service is not started. For details, see 2.3.4 Setting up the environment for the mail system linkage in the JP1/Automatic Job Management System 3 Linkage Guide.
The JP1/AJS3 Database service is controlled by JP1/AJS3. During ordinary operations, you do not need to use the JP1/AJS3 Database service. When the type of the embedded database is one used for JP1/AJS3 - Manager before version 10-00, the JP1/AJS3 Database ClusterService service also starts. However, during ordinary operations, you do not need to use the JP1/AJS3 Database ClusterService service. Use the JP1/AJS3 Database ClusterService service only when you need to operate the embedded database manually.
