In some circumstances you may want to run more than one executable as a service, and these executables may depend on each other. For example, you may want to run a server and a SQL Remote Message Agent to assist in replication.

Services must start in the correct order. If a SQL Remote Message Agent service starts before the server has started, it fails because it cannot find the server.

You can prevent these problems by using service groups, which you manage from Sybase Central.
