Changes Between Versions 5.0 and 5.1 of Java DMK

The following are the main changes and additions to Java DMK since the 5.0 release:

• Instrumentation and Agent services compatible with the latest JMX 1.2 Maintenance Release.

• Secure and interoperable remote access compatible with the new JMX Remote API 1.0 Specification, including support for both the RMI-based and JMXMP-based standard connectors (see Chapter 9, Protocol Connectors).

• Flexible authentication and privacy based on the Simple Authentication and Security Layer (SASL) 1.1 Specification and TLS (see Chapter 11, Connector Security).

• SASL mechanisms providing authentication: SASL-PLAIN, DIGEST-MD5, CRAM-MD5, and GSSAPI/Kerberos (see 11.4.2 SASL Provider).

• SASL mechanisms providing connection privacy: DIGEST-MD5 and GSSAPI/Kerberos (see 11.4.1 SASL Privacy).

• Fine-grained access control based on an authenticated client (see 11.3 Fine-Grained Security).

• Wrapping of existing Java DMK 5.0 RMI and HTTP(S) connectors such that applications based on the standard JMX Remote API can interoperate with existing Java DMK-based applications (see 9.5 Wrapping Legacy Connectors).

• Enhanced Cascading service, supporting both the JMX Remote API connectors and the legacy Java DMK connectors (see Chapter 14, Cascading Service).

• Enhanced Discovery service, allowing the discovery of Java DMK based applications using legacy connectors as well as those using the new connectors (see Chapter 15, Discovery Service).
