Similar to setting
connectionAttribute
to "create=true". Only

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

Network client security

The Derby Network Client allows you to select a security mechanism by specifying a
value for the

securityMechanism

property.

You can set the

securityMechanism

property in one of the following ways:

· When you are using the

DriverManager

interface, set

securityMechanism

in a

java.util.Properties

object before you invoke the form of the

getConnection

method, which includes the

java.util.Properties

parameter.

· When you are using the

DataSource

interface to create and deploy your own

DataSource objects, invoke the

DataSource.setSecurityMechanism

method

after you create a DataSource object.

The following table lists the security mechanisms that the Derby Network Client supports,
and the corresponding property value to specify to obtain this security mechanism. The
default security mechanism is the user id only if no password is set. If the password is
