Tuning The System; Installing Third-Party Utilities - Netscape DIRECTORY SERVER 6.2 Installation Manual

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
+ 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 achieve the same by editing this parameter in the
/etc/sysctl.conf
[ 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
/etc/sysctl.conf
/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
