Adaptive Server editions
Adaptive Server is available in the following editions:
• Enterprise Edition – has no limit on scalability and can run all available
options that can be purchased separately.
• Small Business Edition – has some limit on scalability, and can run a
limited set of options that can be purchased separately.
• Developer Edition – has a limit on scalability and includes many of the
options.
Sybase also offers a series of options that you must purchase separately. Some
of these options are intended for an enterprise-level site, and are not available
in the Small Business Edition.
Adaptive Server editions and optional features are unlocked by providing
SySAM licenses. For complete details, see the Sybase Software Asset
Management User’s Guide.
