The Sybase Server
A Sybase server consists of:
a) Two processes, data server and backup server.
b) Devices which house the databases; one database
(master) contains system and configuration data.
c) A configuration file which contains the server
attributes.
Memory Model
The Sybase memory model consists of:
a) The program area, which is where the dataserver
executable is stored.
b) The data cache, stores recently fetched pages
from the database device.
c) The stored procedure cache, which contains
optimized sql calls.
A database device stores the objects that make up
databases.
The term device does not necessarily refer to a
distinct physical device: it can refer to any piece of a
disk (such as a disk partition) or a file in the file
system that is used to store databases and their objects.
Each database device or file must be prepared and made
known to Adaptive Server before it can be used for database
storage. This process is called initialization.
A segment is a label that points to one or more database
devices. When you first create a database, Adaptive Server
creates three segments in the database,
System: Stores the database?s system tables.
Logsegment: Stores the database?s transaction log.
Default: Stores all other database objects?unless you
create additional segments and store tables or indexes on
the new segments by using create table...on segment_name or
create index...on segment_name
