Examples of commands that do not stop a server cleanly include:
•
Stopping the process in the Windows NT Task Manager Processes
window.
•
Using a UNIX
command.
kill
You can start databases when you start the server, or after the server is running.
To start a database when you start the server, see "Starting the database server"
on page 21 for details.
A database server can have more than one database in use at a time. However,
it is more common to run one database per server, especially in a production
environment.
There are several ways to start a database on a running server.
•
To start a database from DBISQL or Embedded SQL, use the
statement. For a description, see the chapter "SQL
DATABASE
Statements" in the Adaptive Server IQ Reference Manual.
•
To start and connect to a database from DBISQL or Sybase Central, use a
data source that specifies the database file. See "Working with ODBC data
sources".
•
To start and connect to a database when you start DBISQL from a system
command prompt, include the parameter
parameters. See "Connecting to a database from DBISQL".
•
To start a database from Sybase Central, see Chapter 4, "Managing
Databases with Sybase Central" in Introduction to Adaptive Server IQ
•
To start an embedded database, while connected to a server, connect to a
database using a DBF parameter. This parameter specifies a database file
for a new connection. The database file is loaded onto the current server.
The server holds database information in memory using pages of a fixed size.
Once a server has been started, you cannot load a database that has a larger
Catalog page size or IQ page size than the server. For this reason, you should
always set the Catalog page size to its maximum value, 4096 bytes, with the
switch.
