About Adaptive Server

Adaptive Server performs data management and transaction functions, independent of client applications and user interface functions.
Adaptive Server also:

•Manages multiple databases and multiple users
•Keeps track of the data’s location on disks
•Maintains the mapping of logical data description to physical data storage
•Maintains data and procedure caches in memory
Adaptive Server uses these auxiliary programs to perform dedicated tasks:
•Backup Server manages database load, dump, backup, and restoration activities.
•Adaptive Server Enterprise Monitor Historical Server obtains performance data from Monitor Server and saves the data in files for use at a later time.
•XP Server stores the extended stored procedures (ESPs) that allow Adaptive Server to run operating-system level commands.

System-specific issues

Adaptive Server runs on a variety of hardware and operating system platforms. System-specific issues do not affect the basic functionality of Adaptive Server, but there are differences among platform implementations. These differences may include:
•Adaptive Server configuration
•Changes to the operating system that enable or enhance Adaptive Server performance
•Adaptive Server features that are available only on Windows
•The structure of entries in the sql.ini file
•Options for selecting database devices
•Operating system commands or utilities that simplify or automate routine system administration tasks
•Operating system utilities for monitoring Adaptive Server performance
System-specific issues are described in this document. For more information about system-specific issues, see the Installation Guide and release bulletin for your platform.
