You can use the DB2 Driver for JDBC instead of the network
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: com.ibm.db2.jcc.DB2DriverYou
must have the following two jar files present in your classpath in order to
use the DB2 Driver
for JDBC:
- db2jcc.jar
- db2jcc_license_c.jar
The syntax of the URL that is required to access the Network Server is:
jdbc:derby:net://<server>[:<port>]/
<databaseName>[;< URL attribute>=<value> [;...]]
[:<Universal Driver attribute>=<value>; [...;]]
After you specify the database name and attributes, you can include attributes
for the DB2 Driver
for JDBC. You must include a semicolon after the last DB2 Driver for JDBC attribute.
- server
- 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, 158.58.62.225.Unless
the Network Server was started with the -h option or the derby.drda.host property
set, this value must be localhost.
- port
- 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 for
more information about defining the system home.
- URL attribute=value
- Optional database connection URL attributes that are supported by . See the for more information.
- Universal Driver Attribute=value
Optional database connection URL attributes that are supported by the DB2 Driver
for JDBC.
The DB2 Driver for JDBC requires that you set the user and
password attributes to non-null values.
The following DB2 Driver for
JDBC attributes are available to you when running the Network Server:
- user
User name (required by the DB2 Driver for JDBC).
- password
User password (required by the DB2 Driver for JDBC).
- portNumber
The TCP/IP port number where the Network Server listens for connection
requests to this data source. The default is 1527.
- retrieveMessagesFromServerOnGetMessage
Displays error messages from the server.
- readOnly
Creates a read-only connection. The default is false.
- logWriter
A character output stream. All logging and tracing messages print to
the logWriter property.
- traceLevel
Specifies the granularity of tracing messages to the logWriter property.
- traceFile
Provides an explicit file location for the trace output.
- securityMechanism
Indicates what type of security mechanism is used.
- deferPrepares
Controls when prepared statements are physically prepared in the database
server. The default value is true.
