NOTICE : The NDD tcp_rexmit_interval_initial is currently set to 3000
milliseconds (3 seconds). This may cause packet loss for clients on
Solaris 2.5.1 due to a bug in that version of Solaris. If the clients are not
using Solaris 2.5.1, no problems should occur.
NOTICE : If the directory service is intended only for LAN or private
high-speed WAN environment, this interval can be reduced by adding to
/etc/init.d/inetinit:
ndd -set /dev/tcp tcp_rexmit_interval_initial 500
NOTICE : The NDD tcp_ip_abort_cinterval is currently set to 180000
milliseconds (180 seconds). This may cause long delays in establishing
outgoing connections if the destination server is down.
NOTICE : If the directory service is intended only for LAN or private
high-speed WAN environment, this interval can be reduced by adding to
/etc/init.d/inetinit:
ndd -set /dev/tcp tcp_ip_abort_cinterval 10000
NOTICE : The NDD tcp_ip_abort_interval is currently set to 180000
milliseconds (180 seconds). This may cause long delays in detecting
connection failure if the destination server is down.
NOTICE : If the directory service is intended only for LAN or private
high-speed WAN environment, this interval can be reduced by adding to
/etc/init.d/inetinit:
ndd -set /dev/tcp tcp_ip_abort_interval 60000
NOTICE : The NDD tcp_smallest_anon_port is currently 32768. This allows a
maximum of 32768 simultaneous connections. More ports can be made available by
adding a line to /etc/init.d/inetinit:
ndd -set /dev/tcp tcp_smallest_anon_port 8192
WARNING: tcp_deferred_ack_interval is currently 100 milliseconds. This will
cause Solaris to insert artificial delays in the LDAP protocol. It should
be reduced during load testing.
This line can be added to the /etc/init.d/inetinit file:
ndd -set /dev/tcp tcp_deferred_ack_interval 5
WARNING: There are only 1024 file descriptors (hard limit) available, which
limit the number of simultaneous connections. Additional file descriptors,
up to 65536, are available by adding to /etc/system a line like
set rlim_fd_max=4096
