Chapter 10. Security under the IBM Data Server Driver for
JDBC and SQLJ
When you use the IBM Data Server Driver for JDBC and SQLJ, you choose a
security mechanism by specifying a value for the securityMechanism property.
You can set this property in one of the following ways:
v If you use the DriverManager interface, set securityMechanism in a
java.util.Properties object before you invoke the form of the getConnection
method that includes the java.util.Properties parameter.
v If you use the DataSource interface, and you are creating and deploying your
own DataSource objects, invoke the DataSource.setSecurityMechanism method
after you create a DataSource object.
You can determine the security mechanism that is in effect for a connection by
calling the DB2Connection.getDB2SecurityMechanism method.
The following table lists the security mechanisms that the IBM Data Server Driver
for JDBC and SQLJ supports, and the data sources that support those security
mechanisms.
