Requirements
2.2.1. 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 2.1, “Using dsktune”.
