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).
- 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,
Passwordis the same aspassword. - 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 }orPassword={{hello}}.
The following tables describe the connection properties by functionality.
- User ID/password properties
- Proxy server properties
- Data encryption properties
- Bulk load properties
- Failover properties
- Timeout properties
- Client information properties
- Statement pooling properties
- Additional properties
