Chapter 2 Computer System Requirements 35
Verifying Required System Modules
Directory Server is certified to work on:
• The Intel Pentium series processors [i686].
•The default
kernel/glibc revisions that comes along with Red Hat Linux
Advanced Server 3 and the other kernel revisions with their corresponding
glibc revisions as mentioned below.
❍ Default kernel - kernel-2.4.21-3.EL
Kernel used for certification - kernel 2.4.21-4.EL
❍ Default glibc - glibc-2.3.2-95.3
glibc used for certification - glibc-2.3.2-95.20
❍ Required Filesytem:
ext3 (
LARGEFILES support enabled) filesystem has been used for the
certification process.
• With certain installed
rpm packages on Red Hat, the server will not start.
Red Hat distributes two RPM packages for
glibc, one for 386 processors and
higher, the other for 486 or Pentium processors and higher. The 386 package
has no NPTL support. If the 386 package is installed on a machine, you will
lose NPTL support. Once this has happened, it's very hard to detect because
rpm -q reports the package name and version without the architecture tag.
To determine which RPM package is installed, run the following command:
getconf GNU_LIBPTHREAD_VERSION
Installing System Patches
Directory Server has been certified on Red Hat Linux Advanced Server 3 with
kernel revisions 2.4.21-4.EL (
kernel-2.4.21-4.EL.i686.rpm) / glibc version
2.3.2-95.20 (
glibc-2.3.2-95.20.i686.rpm). It is recommended that you use these
kernel and glibc versions. If the machine is a single CPU machine, the
corresponding kernel would be of the form
kernel-x.x.x.x. If the machine is a
multi-CPU machine, the corresponding kernel would be of the form
kernel-smp-x.x.x.x.
You can get the list of installed software, including patches, on your system by
running
rpm -qa.
