The server name is the Adaptive Server to which clients connect.
Server names can be no more than 11 characters long. However, if you installed Adaptive Server on a FAT (file allocation table) partition, limit the server name to 8 characters.
The initial character of a server name must be a letter (a–z, A–Z). The characters that follow can be letters, numbers, the underscore character (_), the pound sign (#), the at sign (@), or the dollar sign ($).
The name cannot contain a period (.), a slash (/), a backslash (\), an accented letter, a character from a Japanese character set, or any other character that is invalid for Windows file names.
Adaptive Server names are not case-sensitive. For example, “PRODUCTION,” “Production,” and “production” are interpreted as the same server name.
