4 SAP ASE Components

SAP ASE is based on a client/server model, communicating with its clients over the network via the Tabular Data

Stream

™

(TDS) protocol. Each client process may execute on one machine and communicate with a database

server on the same or a different machine.

SAP ASE runs as an application on top of an operating system. The hardware that the operating system runs on is

completely transparent to SAP ASE, which sees only the operating system's user interfaces. To enhance

performance on multiprocessor systems, configure multiple processes (engines).

SAP ASE is divided into a DBMS component and a kernel component. The kernel component uses the operating

system services for process creation and manipulation, device and file processing, and interprocess

communication. The DBMS component manages SQL statement processing, accesses data in a database, and

manages different types of server resources.

4.1 SAP ASE Editions

Analyze your system and scalability requirements to determine which edition of SAP ASE is appropriate for your

enterprise.

● Enterprise edition – has no limit on scalability and supports all of the options that can be purchased or

licensed separately.

● Small business edition – has limited scalability, and supports a limited set of the options that are purchased

or licensed separately.

● Developer edition – has limited scalability and includes many of the options that are included in the enterprise

edition.

See the SySAM Users Guide for information about unlocking editions and optional features.

The SAP ASE installer automatically installs a SySAM license server if you choose the full installation option or

enter a served license when prompted for the SySAM license key. You can also install the license server using the

installer's custom installation option. See the SySAM Users Guide to generate licenses.

4.1.1 Determining the Edition You Have
