solaris创建smf实例-用ndd修改tcp/ip协议簇参数

本来修改以下几个tcp/ip内核参数

• tcp_conn_req_max_q
• tcp_keepalive_interval
• tcp_ip_abort_cinterval
• tcp_ip_abort_interval

手工修改的命令示例：

bash-3.00# ndd /dev/ip \? |grep abort
bash-3.00# ndd /dev/tcp \? |grep abort
tcp_ip_abort_cinterval (read and write)
tcp_ip_abort_linterval (read and write)
tcp_ip_abort_interval (read and write)

root@kvamdb1 # ndd -set /dev/tcp tcp_ip_abort_cinterval 60000
root@kvamdb1 # ndd -set /dev/tcp tcp_ip_abort_interval 180000

创建SMF服务的过程如下

Tuning TCP Settings on Solaris 10 Systems

On Solaris 10 systems, the simplest way to tune TCP settings is to create a simple SMF service as follows:

• Create an SMF profile for Directory Server tuning.

• Edit the following xml file according to your environment and save the file as/var/svc/manifest/site/ndd-nettune.xml.

• Before you import the ndd-nettune.xml configuration, verify that the syntax is correct. You can do this by running the following command:

  
  

  $ svccfg validate /var/svc/manifest/site/ndd-nettune.xml
  

• Import the configuration by running the following command:

  
  

  $ svccfg import /var/svc/manifest/site/ndd-nettune.xml
  

  For more information see the svccfg(1M) man page.

• Copy the following shell script into /lib/svc/method/ndd-nettune.

  #!/sbin/sh
  #
  # ident   "@(#)ndd-nettune.xml    1.0     01/08/06 SMI"
  
  . /lib/svc/share/smf_include.sh
  . /lib/svc/share/net_include.sh
  
  # Make sure that the libraries essential to this stage of booting  can be found.
  LD_LIBRARY_PATH=/lib; export LD_LIBRARY_PATH
  echo "Performing Directory Server Tuning..." >> /tmp/smf.out
  /usr/sbin/ndd -set /dev/tcp tcp_conn_req_max_q 1024
  /usr/sbin/ndd -set /dev/tcp tcp_keepalive_interval 600000
  /usr/sbin/ndd -set /dev/tcp tcp_ip_abort_cinterval 10000
  /usr/sbin/ndd -set /dev/tcp tcp_ip_abort_interval 60000
  
  
  # Reset the library path now that we are past the critical stage
  unset LD_LIBRARY_PATH
  

• Run svcadm to enable nettune (for more information, see the svcadm(1M) man page).

• Run svcs -x (for more information see the svcs(1) man page).
