千家信息网最后更新 2024年11月27日Oracle Study之-AIX6.1构建Oracle 10gR2 RAC(2)

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   rootaix204   rootaix203-vip rootaix204-vip rootaix203-priv rootaix204-priv rootaix203   oracleaix204   oracleaix203-vip  oracleaix204-vip  oracleaix203-priv  oracleaix204-priv  oracle[root@aix203 /]#cat .rhostsaix203   rootaix204   rootaix203-vip rootaix204-vip rootaix203-priv rootaix204-priv rootaix203   oracleaix204   oracleaix203-vip  oracleaix204-vip  oracleaix203-priv  oracleaix204-priv  oracle[oracle@aix203 ~]$cat .rhostsaix203   rootaix204   rootaix203-vip rootaix204-vip rootaix203-priv rootaix204-priv rootaix203   oracleaix204   oracleaix203-vip  oracleaix204-vip  oracleaix203-priv  oracleaix204-priv  oracle

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 /]#l***c -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  Debug/Tracing:   DISABLED  Root distance:   0.000000  Root dispersion: 0.000000  Reference ID:    no refid, system is insane  Reference time:  no reftime, system is insane  Broadcast delay: 0.003906 (sec)  Auth delay:      0.000122 (sec)  System flags:    bclient pll monitor filegen   System uptime:   5 (sec)  Clock stability: 0.000000 (sec)  Clock frequency: 0.000000 (sec)  Peer: 127.127.1.0       flags: (configured)(refclock)       stratum:  3, version: 3       our mode: client, his mode: server 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_finwait2 = 1200           tcp_icmpsecure = 0          tcp_init_window = 0    tcp_inpcb_hashtab_siz = 24499              tcp_keepcnt = 8             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_sendspace = 16384            tcp_tcpsecure = 0             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
no -p -o sb_max=1310720
no -p -o tcp_recvspace=65536
no -p -o tcp_sendspace=65536
no -p -o udp_recvspace=655360
no -p -o udp_sendspace=65536

[root@aix203 /]#sh chnet.sh
