OpenLink's Single-Tier drivers pass a name and a set of database-specific connection parameters. You may name your Data Source Name anything you want, so long as it observes length and special character considerations. However, you should consult your Database Administrator, if you need assistance with the database-specific connection parameters.
The database-specific parameters are parameters that the various database native clients use to connect to the database. OpenLink Product Support Staff is familiar with many database native clients. However, these products change frequently. Moreover, your Database Administrator and Database Vendor will have more intimate knowledge of these products as they instantiate in your environment.
