About Java ES 5 Update 1 Service Registry

Release 5U1 Service Registry represents a maintenance release that fixes bugs in Release 5 Service Registry. Release 5 Service Registry was a minor feature release with respect to Release 4 Service Registry. It included some improved functionality, updated interfaces, and selected bug fixes.

Service Registry Upgrade Roadmap

The following table shows the supported Service Registry upgrade paths to Java ES 5.

Table 10–1 Upgrade Paths to Java ES 5 Update 1: Sun Java System Service Registry 3.1u1

Java ES Release	Service Registry Release	General Approach	Reconfiguration
Release 5	Sun Java System Service Registry 3.1	Maintenance upgrade. Apply patches.	None
Release 4		Direct upgrade of Service Registry from Release 4 to Release 5U1 is not supported. This upgrade path is supported by first upgrading Release 4 Service Registry to Release 5 Service Registry and then upgrading Release 5 to Release 5U1. The information about upgrading Release 4 to Release 5 is documented in Sun Java ES 5 Upgrade Guide for Microsoft Windows.

Service Registry Data

The following table shows the type of Service Registry data.

Registry/repository data	RegistryDomainR-base\3.1\data	Database and user certificates
Web interface configuration	RegistryDomainR-base\3.1\jaxr-ebxml	Configuration of web interface

Service Registry Compatibility Issues

Release 5U1 Service Registry is backwardly compatible with Release 5 Service Registry.

Service Registry Dependencies

Service Registry dependencies on other Java ES components can impact the procedure for upgrading and reconfiguring Service Registry software. Changes in Service Registry interfaces or functions, for example, could require upgraded version of components upon which Service Registry depends. The need to upgrade such components depends upon the specific upgrade path.

Service Registry has dependencies on the following Java ES components:

• Shared Components. Service Registry has dependencies on specific Java ES shared components, as listed in Table 1–8.

• Application Server. Service Registry depends on Application Server to provide a container for the Service Registry application and, in Release 5 and 5U1, to manage connections to the networked registry and repository database.

• Java DB. Service Registry has a mandatory dependency on Java DB as the default database for storing services and the meta data describing them.
