Accessing the Network Server by using the DB2 Universal Driver
You can use the DB2 Universal Driver instead of the Derby
client driver to connect to the Network Server. Your application needs to
load the driver and connection URL that is specific to the Network Server.
In addition, you specify a user name and password. If you have not set up
authentication, you can use any value for the user name and password. The
driver that you use to access the Network Server is:
must have the following two jar files present in your classpath in order to
use the DB2 Universal Driver:
The syntax of the URL that is required to access the Network Server is:
<databaseName>[;<Derby URL attribute>=<value> [;...]]
[:<Universal Driver attribute>=<value>; [...;]]
After you specify the database name and attributes, you can include attributes
for the DB2 JDBC Driver. You must include a semicolon after the last Universal
- The name of the machine where the server is running. It can be the name
of the machine (for example, buffy) or the IP address, for example, 220.127.116.11.
the Network Server was started with the -h option or the derby.drda.host property
set, this value must be localhost.
- The port that the server is listening to. The default is 1527.
- database name
- The name of the database that you are connecting to. The database name
can be a maximum of 18 characters. You must use quotation marks (") to include
path information in the database name. Alternately, you can specify path information
by setting the property derby.system.home in either the derby.properties file
or in the Java environment when you start the Network Server. See the Derby Developer's Guide for more information
about defining the system home.
- derby URL attribute=value
- Optional database connection URL attributes that are supported by Derby. See the Derby Developer's Guide for more information.
- Universal Driver Attribute=value
Optional database connection URL attributes that are supported by the
DB2 Universal JDBC Driver.
The DB2 JDBC Universal Driver requires that
you set the Universal Driver user and password attributes to non-null values.
following DB2 Universal JDBC Driver attributes are available to you when running
the Network Server:
User name (required by the Universal JDBC Driver).
User password (required by the Universal JDBC Driver).
The TCP/IP port number where the Network Server listens for connection
requests to this data source. The default is 1527.
Displays error messages from the server.
Creates a read-only connection. The default is false.
A character output stream. All logging and tracing messages print to
the logWriter property.
Specifies the granularity of logging messages to the logWriter property.
Provides an explicit file location for the trace output.
Indicates what type of security mechanism is used.
Controls when prepared statements are physically prepared in the database
server. The default value is true.
