With Sybase Central you can specify dependencies for a service. For example:
You can ensure that at least one member of each of a list of service groups has started before the current service.
You can ensure that any number of services start before the current service. For example, you may want to ensure that a particular network server has started before a SQL Remote Message Agent that is to run against that server starts.
From the Context dropdown list, choose the SQL Anywhere 10 plug-in.
In the right pane, click the Services tab.
Select the service, and then choose File > Properties.
The Service property sheet appears.
Click the Dependencies tab.
Click Add Services or Add Service Groups to add a service or group to the list of dependencies.
Select one of the services or groups from the list.
Click OK to add the service or group to the list of dependencies.
