Use the unixODBC command line tool to configure a datasource for Adaptive Server ODBC Driver.
This is a datasource template:
[sampledsn] Description=Sybase ODBC Data Source UserID=sa Password= Driver=Adaptive Server Enterprise Server=sampleserver Port=4100 Database=pubs2 UseCursor=1
# odbcinst -i -s -f dsn template file
where dsn template file is the complete path to the Adaptive Server ODBC datasource template file. This creates entries for the datasource in the odbc.ini file.
