Oracle Study之-AIX6.1构建Oracle 10gR2 RAC(2)

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。

<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.)
Sys peer:        no peer, system is insane
Sys stratum:     16
Sys precision:   -17

Root distance:   0.000000
Root dispersion: 0.000000

System flags:    bclient pll monitor filegen
System uptime:   5 (sec)
Clock stability: 0.000000 (sec)

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<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">                </span>

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
