ndd -set /dev/tcp tcp_conn_req_max_q0 1024
ndd -set /dev/tcp tcp_conn_req_max_q 1024
The tcp_keepalive_interval specifies the interval in seconds between
keepalive packets sent by Solaris for each open TCP connection. This can be
used to remove connections to clients that have become disconnected from the
network.
The
tcp_rexmit_interval_initial value should be inspected when
performing server performance testing on a LAN or high speed MAN or WAN.
For operations on the wide area Internet, its value need not be changed.
The
tcp_smallest_anon_port controls the number of simultaneous
connections that can be made to the server. When
rlim_fd_max has been
increased to above 4096, this value should be decreased, by adding a line
similar to the following to the
/etc/init.d/inetinit file:
ndd -set /dev/tcp tcp_smallest_anon_port 8192
The tcp_slow_start_initial parameter should be inspected if clients will
predominately be using the Windows TCP/IP stack.
Sun Solaris 9 Operating System
If you plan to install Directory Server on a machine running the Solaris 9
operating system (OS), follow the recommendations outlined in these sections:
• Verifying Disk Space Requirements
• Verifying Required System Modules
• Installing Patches
• Tuning the System
• Setting File Descriptors
• Tuning TCP Parameters
In addition to these recommendations, be sure to check the OS vendor’s web
site for the latest information pertaining to your OS version. For example, you
should read the Solaris Operating Environment Security Sun Blueprint at
http://www.sun.com/blueprints/0100/security.pdf for advice on
guarding against potential security threats.
