Overview

The methods described in this chapter are used to start Adaptive Server, Backup Server, and Monitor Server after a shutdown for database maintenance, because of an operating system crash, or for other reasons.

XP Server is not started by the installation process. XP Server is started by

Adaptive Server when an XP command is issued through isql.

You can use Sybase Central to start and stop servers manually or automatically. For more information about Sybase Central, see “Chapter 1, Overview of System Administration,” in the System Administration Guide.

Requirements for starting servers

To start a server, your user account must have:

•Anyone with access to the database servers (execute privileges) and database devices (read/write privileges).

•Access to Adaptive Server distribution files
