Tuning the System
This section contains some basic system tuning information. Keep in mind that
changing any of the following kernel-tuning parameters requires a system reboot.
• NFS Tuning — This tuning is recommended if you are using Directory Server
to write to NFS mounted drives. On Linux, NFS is typically recommended to
be done over TCP and not over UDP. Make the following change to the
/etc/rc.d/init.d/autofs file:
+ localoptions='rsize=8192,wsize=8192,vers=3,tcp'
• TCP Tuning — You can increase number of local system ports available by
running this command:
echo "1024 65000" > /proc/sys/net/ipv4.ip_local_port_range
You can also achive the same by editing this parameter in the
/etc/sysctl.conf file:
[ echo "1024 65000" >> /etc/sysctl.conf ]
• File Tuning — You can increase the file descriptors by running these
commands:
echo "64000" > /proc/sys/fs/file-max
or edit this parameter in the
/etc/sysctl.conf file:
[ echo "fs.file-max = 64000" >> /etc/sysctl.conf ]
echo "* soft nofile 8192" >> /etc/security/limits.conf
echo "* hard nofile 8192" >> /etc/security/limits.conf
echo "ulimit -n 8192" >> /etc/profile
echo "session required /lib/security/pam_limits.so" >>
/etc/security/limits.conf
Installing Third-Party Utilities
You will need the gunzip utility to unpack the Directory Server software. The
GNU
gzip and gunzip programs are described in more detail at
http://www.gnu.org/software/gzip/gzip.html and can be obtained from
many software distribution sites.
You may need Adobe Acrobat Reader to read the documentation. If you do not
have it installed, you can download it from
