root
.
Table 2.2. Red Hat Enterprise Linux Operating System and Hardware Requirements
2.3.1. Red Hat Enterprise Linux Patches
The default kernel and glibc versions for Red Hat Enterprise Linux 4 and 5 are the only required
versions for the Red Hat Directory Server host machine. If the machine has a single CPU, the kernel
must be presented in the form
kernel-x.x.x.x
. If the machine has multiple CPUs, the kernel
must be presented the form
kernel-smp-x.x.x.x
. To determine the components running on the
machine, run
rpm -qa
.
Run the
dsktune
utility to see if you need to install any other patches.
dsktune
helps verify whether
the appropriate patches are installed on the system and provides useful information for tuning your
kernel parameters for best performance. For information on
dsktune
, see
Section 2.2, “Using
dsktune”
.
Criteria
Requirements
Operating System
Red Hat Enterprise Linux 4 AS and ES (x86 and
x86_64)
Red Hat Enterprise Linux 5 Server (x86 and
x86_64)
Required Filesystem
ext3

2.3.2. Red Hat Enterprise Linux System Configuration
After verifying the system's kernel and glibc configuration and installing any required modules and
patches, fine-tune the Red Hat Enterprise Linux system to work with Directory Server. For the best
performance, configure the host server
before
configuring the Directory Server instance by running the
setup-ds-admin.pl
script.
