You can save sets of connection parameters in a data source. All SQL Anywhere interfaces, except Open Client and jConnect, can use data sources.
Start Sybase Central or Interactive SQL and open the Connect dialog (if it doesn't appear automatically).
On the Identification tab, enter a user ID and password.
On the lower half of the Identification tab, do one of the following:
Select the ODBC Data Source Name option and specify a data source name (equivalent to the DataSourceName (DSN) connection parameter, which references a data source in the Windows registry). You can view a list of data sources by clicking Browse.
Select the ODBC Data Source File option and specify a data source file (equivalent to the FileDataSourceName (FILEDSN) connection parameter, which references a data source held in a file). You can search for a file by clicking Browse.
The SQL Anywhere 10 Demo data source holds a set of connection parameters, including the database file and a StartLine (START) parameter to start the database.
