• A System DSN is a global DSN definition that is available to any user and application on a particular
system. A System DSN can normally only be configured by a systems administrator, or by a user
who has specific permissions that let them create System DSNs.
• A User DSN is specific to an individual user, and can be used to store database connectivity
information that the user regularly uses.
• A File DSN uses a simple file to define the DSN configuration. File DSNs can be shared between
users and machines and are therefore more practical when installing or deploying DSN information
as part of an application across many machines.
DSN information is stored in different locations depending on your platform and environment.
20.1.4.2. Connector/ODBC Connection Parameters
You can specify the parameters in the following tables for Connector/ODBC when configuring a DSN:
• Table 20.3, "Connector/ODBC DSN Configuration Options"
• Table 20.4, "Connector/ODBC Option Flags"
Users on Windows can use the Options and Advanced panels when configuring a DSN to set these
parameters; see the table for information on which options relate to which fields and check boxes.
On Unix and Mac OS X, use the parameter name and value as the keyword/value pair in the DSN
configuration. Alternatively, you can set these parameters within the
in the
