**一、查看系统I/O(对于Oracle数据库需启用异步I/O)**

对于AIX6.1，默认异步I/O在有需求时，自动被激活，不需要配置。

[root@aix203 /]#ioo -a |grep aio
 aio_active = 0
 aio_maxreqs = 65536
 aio_maxservers = 30
 aio_minservers = 3
 aio_server_inactivity = 300
 posix_aio_active = 0
 posix_aio_maxreqs = 65536
 posix_aio_maxservers = 30
 posix_aio_minservers = 3
 posix_aio_server_inactivity = 300

**二、配置节点间的主机信任关系：**

[root@aix203 /]#cat /etc/hosts.equiv 
 aix203 root
 aix204 root
 aix203-vip root
 aix204-vip root
 aix203-priv root
 aix204-priv root
 
 aix203 oracle
 aix204 oracle
 aix203-vip oracle
 aix204-vip oracle
 aix203-priv oracle
 aix204-priv oracle
 
 [root@aix203 /]#cat .rhosts
 aix203 root
 aix204 root
 aix203-vip root
 aix204-vip root
 aix203-priv root
 aix204-priv root
 
 aix203 oracle
 aix204 oracle
 aix203-vip oracle
 aix204-vip oracle
 aix203-priv oracle
 aix204-priv oracle
 
 [oracle@aix203 ~]$cat .rhosts
 aix203 root
 aix204 root
 aix203-vip root
 aix204-vip root
 aix203-priv root
 aix204-priv root
 
 aix203 oracle
 aix204 oracle
 aix203-vip oracle
 aix204-vip oracle
 aix203-priv oracle
 aix204-priv oracle

--- 对于另一node（aix204）需要相同的配置 ！

**验证主机信任关系：**  
**\[oracle@aix203 ~\]$rsh aix204 date**  
Tue Mar 15 16:18:47 CDT 2016  
**\[oracle@aix203 ~\]$rsh aix204-priv date**  
Tue Mar 15 16:18:50 CDT 2016  
**\[oracle@aix204 ~\]$rsh aix203 date**  
Tue Mar 15 16:17:12 CDT 2016  
\[oracle@aix204 ~\]$rsh aix203-priv date  
Tue Mar 15 16:18:26 CDT 2016

**三、配置时间同步（NTP)**

**NTP SERVER：  
\[root@aix203 /\]\#cat /etc/ntp.conf **  
\# Default NTP configuration file.  
\#   Broadcast client, no authentication.  
**broadcastclient  
driftfile /etc/ntp.drift  
tracefile /etc/ntp.trace  
server 127.127.1.0  
  
NTP CLIENT:  
\[root@aix204 /\]\#cat /etc/ntp.conf **  
\# Default NTP configuration file.  
\#  
\#   Broadcast client, no authentication.  
\#  
\#broadcastclient  
**driftfile /etc/ntp.drift  
tracefile /etc/ntp.trace  
server 192.168.8.203  
启动ntp services：  
\[root@aix203 /\]\#smit xntpd          ；；启动ntp service  
\[root@aix203 /\]\#lssrc -ls xntpd**

Program name:    /usr/sbin/xntpd 
     Version:         3 
     Leap indicator:  11 (Leap indicator is insane.) 
     Sys peer:        no peer, system is insane 
     Sys stratum:     16 
     Sys precision:   -17

     Root distance:   0.000000 
     Root dispersion: 0.000000

     Clock frequency: 0.000000 (sec) 
     Peer: 127.127.1.0 
          flags: (configured)(refclock)

    Subsystem         Group            PID          Status 
     xntpd            tcpip            3604550      active

**四、配置node间私有网络传输参数  
\[root@aix203 /\]\#lsattr  -El  sys0  -a  pre520tune**  
pre520tune disable Pre-520 tuning compatibility mode True  
**\[root@aix203 /\]\#no -a |grep tcp**

hstcp = 0
           tcp_bad_port_limit = 0
            tcp_cwnd_modified = 0
                      tcp_ecn = 0
           tcp_ephemeral_high = 65535
            tcp_ephemeral_low = 32768
                   tcp_fastlo = 0
         tcp_fastlo_crosswpar = 0

                 tcp_keepidle = 14400
                 tcp_keepinit = 150
                tcp_keepintvl = 150
         tcp_limited_transmit = 1
                  tcp_low_rto = 0
                 tcp_maxburst = 0
                  tcp_mssdflt = 1460
              tcp_nagle_limit = 65535
            tcp_nagleoverride = 0
                   tcp_ndebug = 100
                  tcp_newreno = 1
               tcp_nodelayack = 0
            tcp_pmtu_discover = 1
                tcp_recvspace = 16384

                 tcp_timewait = 1
                      tcp_ttl = 60
               tcprexmtthresh = 3
                 tcptr_enable = 0

**\[root@aix203 /\]\#no -a |grep udp**

udp_bad_port_limit = 0
 udp_ephemeral_high = 65535
 udp_ephemeral_low = 32768
 udp_inpcb_hashtab_siz = 24499
 udp_pmtu_discover = 1
 udp_recvspace = 42080
 udp_sendspace = 9216
 udp_ttl = 30
 udpcksum = 1

**配置脚本：  **            
\[root@aix203 /\]\#cat chnet.sh  
**no -r -o ipqmaxlen=512  
no -p -o rfc1323=1
