The current Open Server is based on proprietary light-weight thread architecture and does not scale to symmetric multiprocessor (SMP) platforms. EAServer is based on native or kernel threads supporting SMP architecture. Migrating to EAServer requires minimal work on the server side, no changes to the client, and allows your Open Server applications to take advantage of many EAServer features.
Refer to the Sybase Open Server documentation for information on the Open Server API. This documentation is available on the Sybase Web site.
