Deleting a service removes the service name from the list of services. Deleting a service does not remove any software from your hard disk.
If you want to re-install a service you previously deleting, you need to re-type the options.
From the Context dropdown list, choose the SQL Anywhere 10 plug-in.
In the right pane, click the Services tab.
In the right pane, select the service you want to remove and from the File menu, choose Delete.
Open a command prompt.
Execute the Service utility using the -d option.
For example, to delete the service called myserv, without prompting for confirmation, type the following command:
dbsvc -y -d myserv
