When connecting to the Network Server, your application needs to
load a driver and connection URL that is specific to the Network Server. In
addition, you must specify a user name and password if you are using authentication.
The driver that you need to access the Network Server is:
org.apache.derby.jdbc.ClientDriver
The syntax of the URL that is required to access the Network Server is:
jdbc:derby://<server>[:<port>]/
<databaseName>[;<URL attribute>=<value> [;...]]
where the
<URL attribute> is either a
Derby embedded or network
client attribute.
Table 1. Standard JDBC DataSource properties

This property is also available using EmbeddedDataSource. |
| dataSourceName |
String |
The data source name. |
|
This property is also available using EmbeddedDataSource. |
| description |
String |
A description of the data source. |
|
This property is also available using EmbeddedDataSource. |
| user |

Table 2. Client-specific DataSource properties
| Property |
Type |
Description |
URL attribute |
Notes |
| traceFile |
String |
The filename for tracing output. Setting this property
turns on tracing. See Network client tracing. |
traceFile |
|
| traceDirectory |
String |
The directory for the tracing output. Each connection
will send output to a separate file. Setting this property turns on tracing.
See Network client tracing. |
traceDirectory |
|
| traceLevel |
Integer |
The level of client tracing if traceFile or traceDirectory are
set. |
traceLevel |
The default is TRACE_ALL. |
| traceFileAppend |
Boolean |
Value is true if tracing output should append to the
existing trace file. |
traceFileAppend |
The default is false. |
| securityMechanism |
Integer |
The security mechanism. See Network client security. |
securityMechanism |
The default is USER_ONLY _SECURITY. |
| retrieveMessageText |
Boolean |
Retrieve message text from the server. A stored procedure
is called to retrieve the message text with each SQLException and might
start a new unit of work. Set this property to false if you do not want the
performance impact or when starting new units of work. |
retrieveMessageText |
The default is true. |
| ssl |
String |
The SSL mode for the client connection. See Network encryption and authentication with SSL/TLS |
ssl |
The default is off. |
Table 3. Server-Specific DataSource properties

URL attributes |
Notes |
| connectionAttributes |
String |
Set to the list of Derby embedded
connection attributes separated by semicolons. |
Various |
This property is also available using EmbeddedDataSource.
See the Java DB Reference Manual for more information
about the various connection attributes. |
| createDatabase |
String |
If set to "create", create the database specified with databaseName property. |
create |
This property is also available using EmbeddedDataSource.
See the Java DB Reference Manual for more information.
Similar to setting connectionAttribute to "create=true". Only "create" is allowed, other values equate to null. The result of conflicting settings of createDatabase, shutdownDatabase and connectionAttributes is undefined. |
| shutdownDatabase |
String |
If set to "shutdown", shutdown the database specified with databaseName property. |
shutdown |
This property is also available using EmbeddedDataSource.
See the Java DB Reference Manual for more information.
Similar to setting connectionAttribute to "shutdown=true". Only "shutdown" is allowed, other values equate to null. The result of conflicting settings of createDatabase, shutdownDatabase and connectionAttributes is undefined.
If authentication and sqlAuthorization are both enabled, database shutdown is restricted to the database owner.

Note that setAttributesAsPassword , which is available for the embedded
DataSource, is not available for the client DataSource.
