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

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。
<strong>[root@aix203 /]#ioo -a |grep aio</strong> 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:
<strong>[root@aix203 /]#cat /etc/hosts.equiv </strong> 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 <strong>[root@aix203 /]#cat .rhosts</strong> 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 <strong>[oracle@aix203 ~]$cat .rhosts</strong> aix203 root aix204 root aix203-vip root aix204-vip root aix203-priv root aix204-priv root aix203 oracle aix204 oracle aix203-vip oracle aix204-vip oracle aix203-priv oracle aix204-priv oracle
--- 对于另一node(aix204)需要相同的配置 !验证主机信任关系:
[oracle@aix203 ~]$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.)

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

[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<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);"> </span>配置脚本:
[root@aix203 /]#cat chnet.sh
