2.3.4.4. Tuning the System
Basic Solaris tuning guidelines are available from several books, including
Sun Performance and
Tuning: Java and the Internet
(ISBN 0-13-095249-4). Advanced tuning information is available
in the
Solaris Tunable Parameters Reference Manual
(816-7137), which can be obtained from
http://docs.sun.com/db/doc/816-7137.
2.3.4.5. Setting File Descriptors
The system-wide maximum file descriptor table size setting limits the number of concurrent connec-
tions that can be established to Directory Server. The governing parameter,
rlim_fd_max
, is set in
the
/etc/system
file. By default, if this parameter is not present, the maximum is 1024. It can be
raised to 4096 by adding a line such as
set rlim_fd_max=4096
to
/etc/system
and rebooting
the system.
Caution
This parameter should not be raised above 4096 without first consulting your Sun Solaris support
representative since it may affect the stability of the system.
You should also set the soft limit for file descriptors:
ulimit -n in csh limit desc 1024
Use the
dsktune
utility (see Section 2.3.1
dsktune
Utility
) to learn about the hard and soft limits
for file descriptors.
2.3.4.6. Tuning TCP Parameters
By default, the TCP/IP implementation in a Solaris kernel is not correctly tuned for Internet or Intranet
services. The following /dev/tcp tuning parameters should be inspected and, if necessary, changed to
fit the network topology of the installation environment.
The
tcp_time_wait_interval
in Solaris 9 specifies the number of milliseconds that a TCP
connection is held in the kernel’s table after it has been closed. If its value is above 30000 (30 seconds)
and the directory is being used in a LAN, MAN, or under a single network administration, it should
be reduced by adding a line to the
/etc/init.d/inetinit
file similar to the following:
