CHAPTER 2 Running Adaptive Server IQ

To create or edit DSNs or File DSNs on UNIX systems, use a text editor. For
DSNs you can edit the .odbc.ini file directly. For File DSNs, create a file with
the name you choose, using the file extension .dsn.

Note

Sybase recommends that, to avoid ambiguity, you be as specific as

possible in creating ODBC and other data sources, whether you create them
using the ODBC Administrator, or by editing odbc.ini, .odbc.ini, or .dsn files
directly. If more than one database is started on a server, for example, you
should specify the database name, and in a network with subnets, specify the

CommLinks

parameter including the host number when editing files; include

the host number in the network protocol options on the Network tab in the
ODBC Administrator.

If connection parameters are incomplete or incorrect, you may see an error
such as

Database name required to start engine

For a complete list of connection parameters, see Chapter 3, “Connection and
Communication Parameters” in Adaptive Server IQ Reference Manual.

Examples of
connection strings
using data sources

The following connection string specifies an ODBC Data Source Name and a
user ID.

DSN=ASIQ sample;uid=DBA

The following connection string specifies a File Data Source Name, with a user
ID and password.

FILEDSN=ASIQ on UNIX;uid=DBA;pwd=SQL

Creating and editing ODBC data sources

You need an ODBC data source on the client computer for each database you
wish to connect to. You probably already have an odbc.ini file on your system.

On Windows NT, the ODBC Administrator provides a central place for
managing ODBC data sources. The following procedure uses the ODBC
Administrator to add a new data source to your existing odbc.ini, or creates a
new file if necessary.

To create ODBC data sources on UNIX systems, see also “Using ODBC data
sources on UNIX”.
