3. System Requirements
This section contains information related to installing and upgrading Red Hat Directory Server 9.1, including prerequisites and hardware or platform requirements.
3.1. Required JRE
Red Hat Directory Server 9.1 requires Oracle Java Runtime Environment (JRE) 1.8.0 or OpenJDK 1.8.0 for Red Hat Enterprise Linux 6.
Important
When the new JRE is installed for Directory Server 9.1, it is no longer possible to manage older instances of Directory Server using the Directory Server Console because the required JREs for the different Directory Server versions are different. You must migrate any older instance to Directory Server 9.1 if you need to manage that instance with the Directory Server Console.
3.2. Perl Prerequisites
Directory Server 9.1 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.
