You can use connection properties to customize the driver for your environment. This section organizes connection properties according to functionality. You can use connection properties with either the JDBC DriverManager or a JDBC data source. For a DriverManager connection, a property is expressed as a key value pair and takes the form property=value. For a data source connection, a property is expressed as a JDBC method and takes the form setproperty(value).

Note:
  • In a JDBC data source, string values must be enclosed in double quotation marks, for example, setUser("abc@defcorp.com").
  • The data type listed for each connection property is the Java data type used for the property value in a JDBC data source.
  • Connection property names are case-insensitive. For example, Password is the same as password.
  • For connection properties that support string values, use the following escape sequence to specify values containing leading or trailing spaces and curly brackets: {value}. For example: User={hello } or Password={{hello}}.

The following tables describe the connection properties by functionality:
