If you are linking to the unixODBC Driver Manager, edit the datasource template and reinstall the datasource using the unixODBC command line tool:
# odbcinst -i -s -f dsn template file
where dsn template file is the complete path to the Adaptive Server ODBC datasource template file.
If you are directly linking to the Adaptive Server ODBC Driver or Sybase iAnywhere ODBC Driver Manager, modify the odbc.ini file.
This is an example of the odbc.ini datasource template file:
[sampledsn] Driver=Adaptive Server Enterprise Server=sampleserver Port=4100 UserID=sa Password= Database=pubs2 HASession=1 SecondaryHost=failoverserver SecondaryPort=5000
