About Release 5U1

Release 5U1 is a maintenance release that fixes bugs in Release 5 Directory Proxy Server . Release 5U1 Directory Proxy Server is still an LDAP proxy, but with new, extensible routing capabilities. Release 5 also enables the Virtual Directory feature, the ability to aggregate multiple data views in a single view. These data views can represent LDAP or SQL accessible data stores.

For more information, see the Sun Java System Directory Server Enterprise Edition 6.2 Release Notes.

Java ES Release 5U1 Upgrade Roadmap

Table 4–1 shows the supported Directory Proxy Server upgrade paths to Release 5:

Table 4–1 Upgrade Paths to Java ES 5 Update 1: Directory Proxy Server 6.2

Java ES Release	Directory Proxy Server Release	General Approach	Reconfiguration Required
Release 5	Sun Java System Directory Proxy Server 6.0	Maintenance upgrade. Apply patches.	None
Release 4		Direct upgrade of Directory Proxy Server from Release 4 to Release 5U1 is not supported. This upgrade path is supported by first upgrading Release 4 Directory Proxy Server to Release 5 Directory Proxy Server 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.

Directory Proxy Server Data

Directory Proxy Server no longer uses Directory Server for storing configuration data. Configuration is performed using the new Directory Service Control Center or Directory Server EE command-line utilities.

The following table shows the type of data that could be impacted by an upgrade of Directory Proxy Server software.

Table 4–2 Directory Proxy Server Data Usage

Type of Data	Location	Usage
Directory Proxy Server configuration data	Directory Proxy Server 6.x: Accessed through Directory Service Control Center and Directory Server Enterprise Edition command-line utilities	Configuration of Directory Proxy Server
Security data	Directory Proxy Server 6.x: SSL configured through Directory Service Control Center and Directory Server Enterprise Edition command-line utilities	Server certificates

Directory Proxy Server Compatibility Issues

Release 5U1 Directory Proxy Server does not introduce any interface changes and is therefore backwardly compatible with Java ES Release 5 Directory Proxy Server.

Directory Proxy Server Dependencies

Dependencies on other Java ES components can impact the procedure for upgrading and reconfiguring Directory Proxy Server software. Directory Proxy Server has dependencies on the following Java ES components: specific Java ES shared components, as listed in Table 1–8. Directory Proxy Server provides front-end access to Directory Server but has no dependency on Directory Server beyond this functional relationship.
