3. System Requirements

This section contains information related to installing and upgrading Red Hat Directory Server 9.0, including prerequisites and hardware or platform requirements.

3.1. Required JDK

Red Hat Directory Server 9.0 requires Sun JRE 1.6.0 or OpenJDK 1.6.0 for Red Hat Enterprise Linux 6.

Important

When the new JDK is installed for Directory Server 9.0, it is no longer possible to manage older instances of Directory Server using the Directory Server Console because the required JDKs for the different Directory Server versions are different. You must migrate any older instance to Directory Server 9.0 if you need to manage that instance with the Directory Server Console.

3.2. Perl Prerequisites

Directory Server 9.0 does not package nsperl with the product. perldap should work with the version of perl pre-installed on the system.
Use the Perl version that is installed with the Red Hat Enterprise Linux operating system in /usr/bin/perl for both 32-bit and 64-bit versions of Red Hat Directory Server.

3.3. Fonts

A font package must be installed before the Directory Server Console can be launched. Any font package is acceptable.

3.4. Software Conflicts

Directory Server cannot be installed on any system that has a Red Hat Enterprise Linux Identity Management server installed. (The Identity Management server is also called an IPA server.)
Likewise, no Red Hat Enterprise Linux Identity Management server can be installed on a system with a Directory Server instance.
