On Unix, if you are setting up the driver in an ODBC system information file (typically called .odbc.ini), the section for this driver should appear as follows (with appropriate values entered for each field):

[sample_dsn_using_the_ias_odbc_driver_for_oracle]
Driver=full-path/libdboraodbc12_r.so
UserID=user-id
Password=password
ServiceName=TNS-service-name
ProcResults=[yes|no]
ArraySize=bytes

For an explanation of each field, see the table in SQL Anywhere 16 - Oracle ODBC driver.
