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 this URL:

Setting File Descriptors
The system-wide maximum file descriptor table size setting will limit the number
of concurrent connections 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 to
/etc/system a line
set rlim_fd_max=4096
and rebooting the system.
You should also set the soft limit for file descriptors:
ulimit -n
in csh limit desc 1024
Use the dsktune utility (see “dsktune Utility” on page 37) to check about the hard
and soft limits for file descriptors.

113993-01: SunOS 5.9: mkfs Patch
114135-01: SunOS 5.9: at utility Patch
CAUTION This parameter should not be raised above 4096 without first
consulting your Sun Solaris support representative as it may affect
the stability of the system.
